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:
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 order to develop an efficient micropropagation system, it is essential to establish the appropriate concentration of growth regulators for seed germination, shoot formation and rooting. Nodal segments from in vitro obtained seedlings of Gentiana lutea L. were cultured in vitro in Murashige and Skoog’s medium supplemented with BAP, Thidiazuron and Zeatin (0.5, 1.0 and 2.0 mg L−1). A maximum number of shoots with the highest height was recorded at 2.0 mg L−1 BAP. For further optimization of the process, we used nutrient media containing BAP and Zeatin with a combination of low concentration of Indoleacetic acid. MS medium containing 2.0 mg L−1 Zeatin and 0.2 mg L−1 IAA resulted in maximum numbers of shoots 94.3) with shoot height 2.5 cm. The multiple plants were successfully ex vitro acclimatized with 65% survival. The presence of growth regulators (2.0 mg L−1 Zeatin and 0.2 mg L−1 IAA) in the nutrient media resulted in an effective antioxidant activity in G. Lutea determined by the low molecular antioxidant metabolites such as phenols and flavonoids and activities of antioxidant enzymes – catalase, ascorbate peroxidase, guaiacol peroxidase, and superoxide dismutase. The described protocol allows the establishment of numerous micropropaged plants of rare and endangered G. lutea.

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:
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.

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:
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:
Asahi SL stimulates plant’s vital processes like growth and development, affects physiology and biochemistry, what often leads to increased biomass accumulation and yield. However, common is opinion that application of this preparation could be beneficial only, when treated plants are grown under unfavorable conditions. Therefore the aim of this work was the assessment of the stimulatory effect of Asahi SL on Arabidopsis thaliana L. and ornamental amaranth plants grown under optimal conditions. Plants treated with Asahi SL were higher and more advanced in development, particularly generative. Biomass accumulation was greater after biostimulator application mainly due to better photosynthetic apparatus efficiency, which was manifested by (i) greater leaf area, (ii) higher total chlorophyll content and (iii) increased intensity of photosynthesis. Effect of Asahi SL on chlorophyll a fluorescence was marginal. Despite of higher transpiration and lowered stomatal resistance the RWC was almost unchanged in biostimulator treated plants what was attributed to increased water uptake. Obtained results clearly showed that Asahi SL applied on plants can also be effective and beneficial when they are grown under optimal conditions.
Asahi SL stymuluje procesy życiowe roślin, jak również wzrost i rozwój oraz wpływa ma procesy fizjologiczne i biochemiczne, co często prowadzi do zwiększenia wytwarzanej biomasy i plonowania. Powszechną jest jednak opinia, że pozytywny wpływ preparatu ma miejsce, tylko wtedy, gdy rośliny rosną w niekorzystnych warunkach. Celem pracy były ocena stymulującego wpływu Asahi SL na rośliny rzodkiewnika pospolitego oraz szarłatu ozdobnego rosnące w warunkach optymalnych. Rośliny traktowane Asahi SL były, wyższe oraz bardziej zaawansowane w rozwoju, szczególnie generatywnym. Preparat podwyższał akumulację biomasy głównie poprzez poprawę sprawności aparatu fotosyntetycznego, która przejawiała się zwiększeniem (i) powierzchni liści, (ii) zawartości chlorofilu oraz (iii) intensywności fotosyntezy. Preparat miał niewielki wpływ na mierzone parametry fluorescencji chlorofilu a. Mimo wyższej transpiracji i obniżonych oporów dyfuzyjnych, u roślin traktowanych preparatem, ich RWC się nie zmieniło, co tłumaczyć można zwiększonym pobieraniem wody z podłoża. Uzyskane w tych badaniach wyniki dowodzą, że Asahi SL działa pozytywnie także na rośliny rosnące w warunkach optymalnych.
