Opis:
The influence of an Uncaria tomentosa extract on the development of Capsicum plants grown in green-house conditions was examined. The effect of the treatment was investigated with microscopic techniques (light and electron microscope) in leaves from three levels of control plants and plants after treatment with the extract added to the soil in doses of 0.4 and 16 mg/ml (200 ml per pot/plant). In control leaves, changes typical of the subsequent phases of normal development were observed: nuclear chromatin became slightly condensed, plastoglobuli of chloroplasts increased in number and size, intragranal thylakoids were somewhat dilatated. In addition to such commonly occurring changes, some symptoms typical of pepper were observed in the ontogenesis of the examined plant: an increased number of spherical electron-dense deposits in vacuoles, an increased number of peroxisomes, the occurrence of numerous paracrystalline structures in chloroplasts of mature leaves, and, starting in mature leaves, expulsion of plastoglobuli from chloroplasts. After the treatment, most of those changes, leading to ageing, occurred much earlier and were more distinct. Chloroplasts, already in the youngest examined leaves, showed dilatation of intergranal thylakoids, which intensified with aging of the leaves and degradation of grana in the oldest leaves. Starch grains decreased in size and number and plastoglobuli became large. Vesiculation of ground cytoplasm in all leaves was stronger than in the control. No paracrystalline structures in chloroplasts or expulsion of plastoglobuli were observed. Another unusual phenomenon was the disappearance of spherical electron-dense deposits in the central vacuoles of cells. Those observations suggested that U. tomentosa extract enhanced the natural ontogenesis of Capsicum annuum leaves, by accelerating and enhancing the typical characteristics of ageing, and, additionally, it changed the structure and physiology of cells.

Opis:
In this study, an attempt was made to investigate in vitro morphogenetic competence of three shrub species from the Thymelaeaceae family. The studied plant material originated from Russia, Greece and China, and the effectiveness of in vitro shoot formation and rhizogenesis of Daphne caucasica, D. jasminea, and D. tangutica was verified. The multiplication coefficient was compared for different propagation media. Medium composed of WPM mineral salts, MS microelements and a set of vitamins, supplemented with 1.0 mg dm-3 2iP, 0.1 mg dm-3 NAA, and 0.65 g dm-3 calcium gluconate, was appropriate for micropropagation of the tested genotypes. Shoot propagation in medium containing B5 vitamins and microelements was not as effective as on WPM/MS medium. The rooting phase, especially in D. tangutica, needs further optimization in order to reduce the costs associated with acclimatization of microplantlets obtained to in vivo conditions. After stabilization, the plants were successfully cultivated under greenhouse conditions.
Badano kompetencję morfogenetyczną trzech gatunków roślin krzewiastych z rodziny wawrzynkowatych. Materiał roślinny pochodził z Rosji, Grecji i Chin. Regenerowano in vitro pędy i korzenie przybyszowe u wawrzynka kaukaskiego (Daphne caucasica), wawrzynka jaśminowego (D. jasminea) oraz wawrzynka tanguckiego (D. tangutica). Pożywka składająca się z zestawu soli mineralnych dla roślin drzewiastych (WPM), mikroelementów i witamin według Murashige i Skooga (MS), wzbogacona o 1.0 mg×dm-3 2iP, 0.1 mg×dm-3 NAA i 0.65 g×dm-3 glukonianu wapnia okazała się odpowiednia do mikrorozmnażania badanych genotypów. Namnażanie pędów na pożywce zawierającej zestaw witamin według Gamborga i współpracowników (B5) było mniej efektywne niż na pożywce WPM/MS. Etap ukorzeniania, szczególnie dla wawrzynka tanguckiego, wymaga dalszej optymalizacji w celu zmniejszenia kosztów ponoszonych w trakcie uzyskiwania materiału przydatnego do uprawy. Otrzymane drogą rozmnażania in vitro rośliny przystosowano do uprawy w warunkach szklarniowych.

Opis:
The experiment was carried out to determine the effects of different irrigation water levels on yield and some quality parameters of lettuce (Lactuca sativa L. Var. Longifolia cv.) under greenhouse conditions. Irrigation water was applied through drip irrigation method with 7 days interval during the total growing season. Irrigation treatments consisted of six different water levels (I1: non-irrigation, I2: 25 %, I3: 50 %, I4: 75 %, I5: 100 % and I6: 125 % of cumulative evaporation measured from Class A pan). The amount of irrigation water ranged between 0 and 106.3 mm among the treatments. Evapotranspiration (ET) values varied from 69.1 to 158.5 mm for the treatments. The highest yield was obtained from the I5 followed by I4. A significant polynomial relation (R2=0.77) was obtained between the yield and irrigation water, and linear relation (R2=0.99) was obtained between the yield and ET. This indicated that when irrigation water increased, yield also increased to a certain point. However, when the amount of irrigation water exceeded the plant water requirement, lettuce yield decreased. Yield response factor (Ky) was determined as 1.97. Since Ky ˃ 1, lettuce was very sensitive to water deficiency. In addition, the highest water use efficiency (WUE) and irrigation water use efficiency (IWUE) values were calculated in the I5 with 0.60 t ha.mm-1 and 0.96 t ha.mm-1 respectively. The best plant quality parameters which were plant weight (239.11 g), plant height (26.30 cm), plant diameter (44.82 cm), root weight (17.31 g), root length (9.02 cm), root diameter (10.04 cm) and leaf number (49) were also obtained in I5. As a result, it was suggested that I5 can be the most appropriate irrigation water level for lettuce with higher WUE, IWUE, yield and quality under greenhouse conditions.

Opis:
Rhizomania is one of the most important diseases of sugar beet around the world – including in Iran. The disease causes a severe decrease in sugar yield and is a limiting factor in sugar beet cultivation. Control of the disease is very difficult due to the long-term survival of its fungal vector (Polymyxa betae) in the soil. In this study, we investigated the effects of antagonistic fungal isolates on the population of the resting structure (cystosorus) of P. betae, under greenhouse conditions. Antagonistic fungi, including Trichoderma harzianum and Talaromyces flavus, were isolated from soil samples collected from sugar beet infested fields in the Semnan Province of Iran. In the next step, their inocula were prepared through reproduction on rice bran. For evaluation of the efficacy of antagonists in greenhouse conditions, a split plot trial was conducted and performed. The main factor was three different methods of application of T. flavus as the soil treatment, seed treatment, and a combination of both methods. The sub-factor was the use of different fungal isolates. To determine the cystosorus population of the fungal vector, seedling roots in all treatments were stained with lactic acid and fuchsine (lactofushine), 60 days after sowing. The number of cystosorus in one gram of root was counted using a light microscope and hemocytometer. At the end of the study, average root weight in different treatments was also measured to select and introduce the best treatments in regard to their effects on root weight. According to the results, the number of cystosorus in 1 g of root was different in various treatments and those treatments containing TF-Su-M-1, TF-Su-M-2, TH-Su-M-1, and TH-Su-M-2 used as a soil application method were more effective in the reduction of the cystosorus population and root weight increase. Among the above-mentioned treatments, maximum reduction of cystosori population and the increase in root weight were observed in TH-Su-M-1 and TF-Su-M-2 through the soil application method.

Opis:
A detailed, species-specific comprehension of plant water behavior can be a central tool to improve water management in nursery production and irrigated landscapes. Potted plants of Nerium oleander, Pittosporum tobira, and Ligustrum japonicum ‘Texanum’ were exposed to controlled increasing drought conditions in greenhouse. Water use, gas exchange, and foliar thermoregulation were monitored along the trial. N. oleander showed the most efficient response to increasing water stress, maintaining high levels of gas exchange and evapotranspiration rate during the whole trial, whereas L. japonicum emerged as the most sensitive species, with a significant drop in physiological performances already from the second day. The more aggressive water behavior of N. oleander can be compared to the one of anisohydric plants, whereas L. japonicum displays an isohydric strategy. P. tobira showed intermediate characteristics between the two other species. This work comes to provide useful tools for the management of irrigation in plant nursery and for decision making in the use of ornamental shrubs for landscape applications.
