Opis:
A field experiment was carried out during 2017–2018 in the Horticulture Research Station farm in El Kanater El Khayreia, El Kalubeia Governorate, Egypt, to find out the response of foliar application of melatonin, GA3 and NAA on vegetative and fruit attributes of ‘Canino’ apricot. Different plant growth regulators influenced all variable parameters related to vegetative growth and fruit. Results revealed that between all growth regulators, the foliar application of melatonin following by GA3 there was the highest vegetative growth as compared to other treatments, while GA3 gave the highest yield following by melatonin as compared to other treatments. Treatment with NAA improved vegetative growth, yield and fruit quality to a lesser extent as compared to the control.

Opis:
One of the ways to reduce the water consumption by plants while maintaining their proper quality is to use substances that limit excessive transpiration. Three preparations at following concentrations: Moisturin (10%), Root-Zone (4.5%) and Vapor Gard (1%), were used in the experiment. Moisturin and Vapor Gard were applied in the form of a single spray, and Root-Zone as a single irrigation in mid July.The aim of the research was to assess the effect of several anti-transpirants on some biometric features of the ‘Tardiva’ panicled hydrangea depending on the frequency of irrigation. The following parameters were measured: area, perimeter, width and length of leaf blade, length and width of inflorescences, and the diameter of shoots. Treatment of H. paniculata cv. ‘Tardiva’ with Root-Zone and Moisturin anti-transpirants with a single irrigation every other day allows to reduce the water consumption and obtain shrubs of a quality comparable with plants irrigated twice a day. The use of Moisturin with a twice daily irrigation positively affected the length and width of inflorescences.

Opis:
Effects of prohexadione-calcium (ProCa, 125 and 250 mgL–1) and ProCa + ammonium sulfate (AMS, 500 mgL–1) treatments on vegetative characteristics (shoot growth, branch diameter, trunk cross-sectional area (TCSA), canopy volume, number of flower per cm2, number of fruits per cm2) and quality parameters (fruit size, flesh firmness, color, titratable acidity and soluble solids content (SSC)) of ‘0900 Ziraat’ sweet cherry were investigated in this study. Solutions were sprayed when the shoots were just 10 cm long in 2014 and 2015. As compared to control, in 2015, TCSA decreased only with ProCa treatments (125 and 250 mgL–1) and canopy volume and shoot length decreased with all treatments. On the other hand, number of flower and fruit per cm2 significantly increased with all treatments. While there were not significant differences in fruit size, flesh firmness, color, SSC and titratable acidity values were significantly lower in 250 mgL–1 ProCa and 250 mgL–1 ProCa + AMS treatments. It was concluded that ProCa treatments could be used as an efficient tool for suppression of shoot growth and to increase the number of flower and fruits per cm2 in ‘0900 Ziraat’ sweet cherry cultivar.

Opis:
Water shortage is a major problem that limits growth and productivity of plants in arid and semi-arid regions. Protecting plants from adverse environmental conditions by using simple methods could be of great value under these conditions. In the present study, we examined water status and drought tolerance of snap bean, a drought-sensitive plant, and Jerusalem artichoke, a relatively drought tolerant plant in response to the application of salicylic acid (SA). Different levels of SA were applied and several physiological, growth, productivity and quality parameters were recorded together with the relative water content. Foliar application of SA improved growth, productivity, quality as well as some physiological parameters of snap bean and Jerusalem artichoke plants exposed to drought stress. Total chlorophyll content and relative water content were higher in plants treated with SA compared to control plants when subjected to drought stress. The specific responses of snap bean and Jerusalem artichoke to SA under drought stress as well as the possible explanations of the effects of SA are discussed.

Opis:
Methyl jasmonate (MJ) is a widely occurring molecule. Since it is synthesized constitutively, its presence is substantial to plant normal growth and development. Moreover, its elevated concentration detected under abiotic and biotic stress conditions seems to be crucial to plant in reacting to adverse events and its ability to survive. Because of the sophisticated biochemical machinery inside the plant body, MJ, among other molecules, helps the plant to adopt to the surrounding environmental changes and is involved in its defense system.

Opis:
Stevia rebaudiana Bertoni is a perennial plant belonging to Asteraceae family and its leaves contain steviol glycosides (SGs) that are 150 to 300 times sweeter than sucrose. The sweeteners obtained from S. rebaudiana can be safely used by diabetics as insulin secretion is not required during digestion of this sweetener. As it has zero calories, it is also used in diet products. Adaptation studies for Stevia conducted in Antalya, Turkey have shown that the stevia plant could easily be cultivated as a perennial. However, the lack of a sustainable vegetative propagation method creates a significant problem for stevia production. In the generatively populations, homogeneity and therefore quality are decreased because of cross-pollination. Stevia, as a self-incompatible and cross-pollinated species, has been shown to have very high genetic diversity. Therefore, development of a sustainable in vitro propagation method to prevent genetic heterogeneity of selected varieties is crucial for stevia cultivation. The aim of this study was to evaluate 2 different gelling agents (plant agar and Gelrite) and 20 different growth regulators combinations. The results demonstrated an approximately 200-fold multiplication rate obtained within 13 weeks using MS medium supplemented with 0.5 mg·dm–3 BAP and 0.25 mg·dm–3 kinetin and solidified with Gelrite. Average stevioside and rebaudioside A contents in in vitro propagated plant samples were found to be 8.1% and 8.6%, respectively.

Opis:
Studies were conducted at the Felin Experimental Station of the Agricultural University in Lublin in the years 2001–2003 and their aim was to estimate the effect of preparations Arbolin 036SL and Promalin 3,6 SL in the form of lanolin paste on the quality of two-year-old trees ‘Šampion’ and ‘Jonica’ cvs. grafted on rootstock M.26. It was shown that the greatest influence on the number of lateral shoots, sum of shoot length and their mean length was exerted by the cultivar and atmospheric conditions in a given year. It was observed that in the majority of trees more lateral shoots were formed by the trees after the application of growth regulators as compared to the control. A singular use of preparations stimulating the branching in the form of lanolin paste in the years with unfavourable weather conditions (2003) was not sufficient to obtain satisfactory effect. The genetic features of a cultivar and the weather conditions in the period of young shoots’ growth had a significant effect on the growth of the studied trees. Preparations Arbolin and Promalin in the form of lanolin paste had no significant effect on the diameter of the rootstock trunks.
W latach 2001–2003 w Gospodarstwie Doświadczalnym Felin Akademii Rolniczej w Lublinie, przeprowadzono badania mające na celu ocenę wpływu preparatów: Arbolin 036SL i Promalin 3,6 SL w postaci pasty lanolinowej na jakość drzewek dwuletnich jabłoni odmiany ‘Szampion’ i ‘Jonica’ okulizowanych na podkładce M.26. Wykazano, że największy wpływ na liczbę pędów bocznych, sum długości i średnią ich długość miała odmiana oraz warunki atmosferyczne w danym roku. Zaobserwowano, że u większości badanych drzewek więcej pędów bocznych wytworzyły drzewka po zastosowaniu regulatorów wzrostu niż w kontroli. Jednorazowe zastosowanie preparatów stymulujących rozgałęzianie w postaci pasty lanolinowej w lata o niekorzystnych warunkach atmosferycznych (rok 2003) było niewystarczające do uzyskania zadawalających efektów. Cechy genetyczne odmiany oraz warunki pogodowe w okresie wyrastania młodych pędów miały istotny wpływ na wzrost badanych drzewek. Preparaty Arbolin i Promalin w postaci pasty lanolinowej nie miały istotnego wpływu na średnicę pni podkładek.

Opis:
In vitro flowering and micropropagation are useful for plant breeding programs and commercial production of important ornamental plants. In vitro conditions including media components, kind, concentration and ratio of plant growth regulators and culture conditions significantly affect in vitro flowering and micropropagation. There is no any report dealing with the in vitro flowering of Lisianthus (Eustoma grandiflorum). Here, a protocol was developed for flowering and high frequency in vitro micropropagation of E. grandiflorum, an ornamental plant. Micropropagation is an effective tools for propagation of ornamental plants in large scale. The aim of the present study was to evaluate the effect of different concentrations of NAA and BA on micropropagation and flowering of Lisianthus, in vitro. Used culture medium was MS enriched with 0, 0.1, 0.2 and 2 mg L-1 of NAA and BA. In establishment process of explants, the most shoot length (2.07 cm per plant) was obtained on medium supplemented with 0.1 mg L-1 BA (without NAA). Maximum shoot number (5.80 per plant) was produced in medium containing 0.1 mg L-1 BA along with 0.2 mg L-1 NAA. Bud explants in culture media containing 0.2 mg L-1 NAA (without BA) and 0.1 mg L-1 NAA along with 2 mg L-1 BA produced maximum node number (3.20 per plant). The largest number of root (14.53 per plant) and root length (3.87 cm per plant) were produced on 0.2 mg L-1 NAA without BA, also 0.2 mg L-1 BA plus 0.2 mg L-1 NAA and 0.2 mg L-1 BA without NAA. Explants produced flower on medium containing 0.1 mg L-1 BA along with 0.1 mg L-1 NAA without transition of callus formation. Flower was produced from callus in medium containing 0.1 mg L-1 BA along with 2 mg L-1 NAA. Regenerated plants showed 98% survival in greenhouse during acclimatization. Acclimatized plants were morphologically similar to the mother plants.
Kwitnienie i mikropropagacja in vitro są użyteczne w programach hodowli roślin oraz produkcji komercyjnej ważnych roślin ozdobnych. Warunki in vitro, łącznie ze składnikami pożywek, rodzajem, stężeniem oraz proporcją regulatorów wzrostu roślin, a także warunkami hodowli, w sposób istotny wpływają na kwitnienie i mikropropagację in vitro. Nie istnieje żadne badanie dotyczące kwitnienia in vitro lisanthiusa (Eustoma grandiflorum). W niniejszym badaniu opracowano kwitnienie i wysoką częstotliwość mikropropagacji in vitro dla E. grandiflorum, który jest rośliną ozdobną. Mikropropagacja jest skutecznym narzędziem rozmnażania roślin ozdobnych na dużą skalę. Celem niniejszego badania była ocena wpływu różnych stężeĔ NAA i BA na mikropropagację i kwitnienie lisianthiusa in vitro. Używana pożywka hodowlana została wzbogacona za pomocą 0; 0,1; 0,2 i 2 mg L-1 NAA i BA. Przy powstawaniu eksplantów największa długość łodygi (2,07 cm na roślinę) była uzyskana na pożywce uzupełnionej o 0,1 mg L-1 BA (bez NAA). Maksymalna liczba łodyg (5,80 na roślinę) została wytworzona na pożywce zawierającej 0,1 mg L-1 BA wraz z 0,2 mg L-1 NAA. Eksplanty pączków na pożywce hodowlanej zawierającej 0,2 mg L-1 NAA (bez BA) oraz 0,1 mg L-1 NAA wraz z 2 mg L-1 BA wytworzyły maksymalną liczbę węzłów (3,20 na roślinę). Największą liczbę korzeni (14,53 na roślinę) oraz największą długość korzenia (3,87 na roślinę) zaobserwowano na 0,2 mg L-1 NAA bez BA jak również 0,2 mg L-1 BA plus 0,2 mg L-1 NAA oraz 0,2 mg L-1 BA bez NAA. Eksplanty tworzyły kwiat na pożywce zawierającej 0,1 mg L-1 BA wraz z 0,1 mg L-1 NAA bez przeniesienia kalusa. Kwiat był tworzony z kalusa na pożywce zawierającej 0,1 mg L-1 BA wraz z 2 mg L-1 NAA. Zregenerowane rośliny wykazały 98% przeżycie w szklarni podczas aklimatyzacji. Zaaklimatyzowane rośliny były morfologicznie podobne to swych roślin macierzystych.

Opis:
A protocol was developed for high frequency and low cost of in vitro shoot proliferation and ex vitro rooting of Eustoma grandiflorum (Gentianaceae) on solid medium. Shoot tips as explants were cultured on Murashige and Skoog (MS) medium enriched with different concentrations of 2,4-dichlorophenoxyacetic acid (2,4-D) (0.00, 0.01, 0.10 and 1.00 mg l–1) and 6-benzylaminopurine (BAP) (0.00, 0.50, 2.00 and 5.00 mg l–1). Three culture media systems (solid, liquid and double-phase) were applied. None of the explants cultured on liquid and double-phase media resulted in live plant production. Maximum axillary shoot number (54.45) was recorded in the plantlets treated with 0.10 mg l–1 2,4-D in combination with 5.00 mg l–1 BAP. Treatment of 0.01 mg l–1 2,4-D along with 0.50 mg l–1 BAP produced maximum node number and internode length. Some shoots produced on medium containing plant growth regulators (PGRs) were rooted in soil. The largest number (5.50/plantlet) and longest length of root (7.75 cm/plantlet) were obtained in ex vitro condition on the base of shoots produced in culture medium enriched with 0.10 mg l–1 2,4-D along with 0.50 mg l–1 BAP. The combination of 1.00 mg l–1 2,4-D and 0.50 mg l–1 BAP was found to be the most suitable PGRs for obtaining the highest callus weight. The most fresh weight was calculated from plantlets grown on the medium containing 0.10 mg l–1 2,4-D along with 5.00 mg l–1 BAP. Maximum dry weight was obtained in free-PGRs medium. About 90% of the rooted plantlets were established successfully in cultivation beds. Acclimatized plants were morphologically similar to the mother plants.

Opis:
In four-year-lasting field experiment yielding and chemical composition of goldenrod (Solidago virgaurea L. ssp. virgaurea) herb depending on different methods of plantation establishment and natural growth regulator Atonik application were analysed. In the experiment different methods of goldenrod plantation establishment were compared: A. direct spring diaspores sowing, B. spring planting of seedlings, C. direct autumn diaspores sowing, D. autumn planting of seedlings as well as spraying with 0.1% solution of Atonik twice a year. Diaspores were sown directly onto the field in rows 40 cm apart, whereas seedlings were produced in multicell trays in plastic tunnel throughout 5 weeks and then transplanted onto the field in 40 cm × 15 cm raw spacing. Raw material was harvested every year at the beginning of blooming stage and after that chemical analyses comprised leiocarposide content (by HPLC method) were done. The highest yields of raw material were obtained in the second and third years of cultivation, while in the fourth year a considerable yields decrease was observed, indicating that goldenrod plantation should last two or three years. Higher raw material yields characterized by higher leiocarposide content were collected from the plots with spring seedlings transplanting or autumn diasporas sowing, thus these methods of plantation establishment should be recommended on commercial plantations of goldenrod. Additionally, plants should be sprayed with 0.1% Atonik in order to increase raw material yields.
W czteroletnim doświadczeniu polowym badano wpływ różnych metod zakładania plantacji oraz stosowania naturalnego regulatora wzrostu Atoniku na plonowanie i skład chemiczny ziela nawłoci pospolitej (Solidago virgaurea L. ssp. virgaurea). W eksperymencie porównywano następujące metody zakładania plantacji nawłoci: A.  wiosenny siew bezpośredni nasion, B. wiosenne sadzenie rozsady, C. jesienny siew bezpośredni nasion, D. jesienne sadzenie rozsady oraz efekty wykonywanego dwukrotnie w okresie wegetacji oprysku 0,1% roztworem Atoniku. Nasiona wysiewano wprost go gruntu w rzędy co 40 cm, natomiast rozsadę produkowano w tunelu w paletach wielokomórkowych przez okres 5 tygodni, a potem wysadzano na pole w rozstawie 40×15 cm. Surowiec nawłoci zbierano każdego roku na początku kwitnienia roślin, następnie oznaczono w nim zawartość lejokarpozydu (metodą HPLC). Najwyższe plony surowca otrzymywano w drugim i trzecim roku uprawy, podczas gdy w czwartym roku obserwowano znaczną obniżkę plonowania roślin, wskazującą, że plantacja produkcyjna tej rośliny winna trwać przez dwa lub trzy lata. Wyższe plony ziela charakteryzujące się większą zawartością lejokarpozydu zebrano z poletek z wiosennym wysadzaniem uprzednio wyprodukowanej rozsady lub jesiennym wysiewem nasion wprost do gruntu, zatem te dwie metody zakładania plantacji mogą być polecane w polowej uprawie nawłoci. Dodatkowo, w celu zwiększenia plonów surowca rośliny powinny być opryskiwane 0,1% Atonikiem.

Opis:
The aim of the work was to evaluate the influence of cytokinins on in vitro propagated dahlia and their consequent effect on acclimatization. Plant material consisted of shoot tips and nodes. Among the three cytokinins, benzyladenine, kinetin and 2-isopentenyl-adenine, only BA effectively stimulated the shoot multiplication from axiliary buds. The highest multiplication rate was obtained from nodes in the presence of 0.25– 0.5 mg·dm–3 BA. Higher concentrations shortened the internodes and decreased the leaf blades and growth of callus. 1 mg·dm–3 of KIN and 2iP positively influenced the shoot growth and size of leaves. Gibberellic acid (GA3) used with BA increased the number of auxillary shoots. The best quality shoots and the highest multiplication rate were obtained when 2 mg·dm–3 BA was used with 5 mg·dm–3 GA3. Cytokinins affected the rooting and acclimatization ex vitro. Dahlia shoots multiplicated in the presence of 1 mg·dm–3 KIN or 2iP rooted faster in the soil and 100% survived in field, while those from 1 mg·dm–3 BA media rooted slowly, had shorter shoots and only 60% of them survived. Plants bloomed after 11–12 weeks in the field. Dahlia plants that had been multiplicated in the presence of KIN had larger diameter and fresh weight in the field. BA and 2iP positively influenced the flower diameter, length of flower stalk and a number of the first-order shoots.

Opis:
Autumn daffodil (Sternbergia lutea) is a rare and endangered bulbous plant with yellow flowers grown naturally in Iran and unfortunately for different reasons this plant is at the risk of eradication. Natural multiplication rate of S. lutea is low, thus propagation by chipping method is one inexpensive and simple way to overcome this problem. This research was therefore performed to investigate the propagation method in two experiments. In the first experiment, the effects of some plant growth regulators (PGRs) on induction and regeneration of bulblets from bulb chips (propagules) were evaluated. The propagules were prepared by chipping method and treated with indole butyric acid (IBA), gibberellic acid (GA3), benzyl adenine (BA), kinetin (Kin) and cycocel (CCC) at 100 and 200 mg L–1 concentrations for 2 h and then incubated for two months at 20 ±1°C. At the end of incubation, the results showed the highest percentage of concurrent bulblet + root regeneration (CBRR), number and fresh weight of bulblets related to 100 mg L–1 GA3. The highest percentage of only bulblet regeneration (OBR), only root regeneration (ORR) and non-regeneration were obtained at 200 mg L–1 IBA, 100 mg L–1 Kin and control (distillated water: DW) treatments, respectively. In the second experiment, the bulblets that had rooted from each treatment of the first experiment were planted and the produced bulbs were compared. The results indicated that the highest percentage of bulblet sprouting, bulb number and diameter were found at 100 mg L–1 GA3. Therefore, the application of GA3 with mentioned concentration is appropriate for vegetative propagation of this plant by bulb chipping.

Opis:
The published results on plant propagation m vitro culture show the importance of maternal plant age in a successful regeneration process. It is known that initiation effectiveness is low when primary explants are taken from old trees. The aim of this study was an attempt to regenerate Syringa vulgaris from an old specimen of Dendrological Garden in in vitro culture. April turned out to be the optimal month for collecting explants. The highest percentage of initiated shoots were obtained on MS medium containing 7.5 mg⋅dm⁻³ BAP and 0.02 mg⋅dm⁻³ NAA. The highest propagation efficiency was received on MS medium with a double amount of MgSO₄ supplemented with 1.0 mg⋅dm⁻³ BAP. Insignificant effects were observed on the media with cytokinin BAP. The plants with the best-developed root system were obtained on MS medium with reduced to ¼ amount of macro- and micronutrients supplemented with 5.0 mg·dm⁻³ IBA.
W badaniach nad rozmnażaniem roślin w kulturach in vitro podkreśla się wpływ wieku rośliny matecznej na powodzenie procesu regeneracji. Efektywność inicjacji kultur ze starych okazów drzew jest niska. Celem badań była próba regeneracji w kulturach in vitro lilaka zwyczajnego Syringa vulgaris z okazu mającego 80 lat. Optymalnym terminem pozyskiwania eksplantatów z kolekcji był kwiecień. Najlepsze wyniki na etapie inicjacji otrzymano na pożywce MS uzupełnionej 7,5 mg·dm⁻³ BAP i 0,02 mg·dm⁻³ NAA. Najwyższy współczynnik rozmnożenia roślin otrzymano na pożywce MS z podwojoną ilością MgSO₄ i uzupełnionej 1,0 mg·dm⁻³ BAP. Nieistotnie niższe wyniki otrzymano na pozostałych pożywkach zawierających BAP w swoim składzie. Najlepiej rozwinięty system korzeniowy obserwowano u roślin ukorzenianych na pożywce zawierającej ¼ makro- i mikroelementów pożywki MS, uzupełnionej 5,0 mg·dm⁻³ IBA.

Opis:
Initiation of tissue culture of many plant species is a very difficult stage due to appearance of many contaminations. The other problem might be a choice of media for regeneration. Initiation of grass species tissue cultures are thought to be very difficult. Therefore, a research was undertaken to evaluate the use of nano-silver particles for plant material disinfection and to estimate a medium Pennisetum alopecuroides. The plant material were buds and nodal explants that were disinfected in 2% NaOCl for 30 min or 0.1% HgCl2 for 1 min. Half of the explants disinfected with NaOCl were soaked in 50, 100 or 250 mg·dm–3 Ag NPs for 1 hour. Explants not soaked in nano-silver were placed on media with Ag NPs at concentrations of 4, 8 or 16 mg·dm–3. An influence of growth regulators on Pennisetum alopecuroides was evaluated in vitro. Regenerated shoots were placed on MS media with: 3 mg·dm–3 BA + 0.3 mg·dm–3 IBA, 3 mg·dm–3 KIN + + 0.3 mg·dm–3 IAA, 1 mg·dm–3 BA + 0.1 mg·dm–3 IBA. It was observed that the use of nano-silver particles lowered the level of contamination. The best results were obtained when Ag NPs was used at concentration of 100–250 mg·dm–3 alone or as a supplementation of the media, at concentration of 4 mg·dm–3 for nodes and 16 mg·dm–3 for adventitious buds. The use of nodal explants allowed to obtain less contamination. Regeneration depended on a media content. The most regenerated shoots were obtained on the MS media supplemented with 1 mg·dm–3 BA and 0.1 mg·dm–3 IBA.
