Abstract In order to evaluation of seed (pod) priming and seed size (pod) effects on growth and anti oxidant enzymes activity of sainfoin (onobrychis viciifolia Scop.) seedling in normal and drought condition, this experiment was carried in green house condition in 2010. Treatments (16) included: two masses (Borojen and Ghazvin), two seed sizes (large, >4.5 mm and small, 4.5>…>3.5 mm) and four ...
This research was carried on in order to investigate the response of wheat cultivars to salinity tension as factorial experiment and in complete randomized block design in four replications in Islamic Azad University Shoushtar Branch. In this experiment the response of nine wheat cultivars including Chamran, Karchia66, Mahoti, Roshan, Alvand, Kavir, Ghods, Atrak and Tjan at vegetative growth st...
Loblolly pine seedlings were grown in 1 x 5 inch biodegradable plastic tubes for 10, 12, and 14 weeks at densities of 42, 84, 126, and 168 per square foot. Seedling density and age significantly affected seedling development at time of outplant ing, and densi ty became more important as greenhouse growing t imes increased. Al l morphological characteristics measured when seedlings were planted-...
In Iran, Acacia victoriae is not native to tree in Iran but it is used for important goals such as stabilize hills and the beautify landscape in the southern regions of the Iran, especially in the Khuzestan and Ilam provinces. Researches that include the development of native and non-native trees, which are compatible with the conditions of dusting areas in the western provinces of Iran, are ve...
Stressful parental environments can influence offspring size and development either adaptively or maladaptively, yet little is known about species' differences in this complex aspect of phenotypic plasticity. We performed a reciprocal split-brood experiment to compare transgenerational plasticity in response to drought stress in two closely related annual plant species. We raised inbred replica...
the study was carried out to evaluate the effects of soil application of humic acid and calciumon morpho-physiological traits and na+, mg2+, ca2+ uptake of pistachio seedling (akbari) grown under salt stress. a completely randomized design was used with four replications in greenhouse conditions. the experimental treatment consisted of four levels of humic acid (bis humic) (0, 4, 8 and 12 gr k...
In order to evaluate effect of salinity on the germination and vegetative growth of grassland different salad burent Poterium sanguisorba two different experiments were conducted under laboratory and glasshouse conditions in summer 2010. In the first experiment six ecotypes (Semirom, Fereidonshahr, Tehran, Karsang, Damavand and farokhshahr) and four levels of salinity (0, 4, 8 and 12 dS m-1 of ...
Effects of storage duration and temperature of hydro-primed wheat seeds on seed and seedling quality
Quality of seed as a propagating organ and the most valuable input to produce crops is highly important in agriculture. Thus, the objective of this study was to compare the effects of storage temperature (15, 20 and 25 °C) and storage duration (0, 2, 4, 6 and 8 days) of hydro-primed wheat seeds of Koohdasht dry land cultivar on germination and seedling characteristics. The seeds were hydro-prim...
Background: Plant growth regulators (PGRs) have important roles in many processes such as germination, seedling growth, nutrition uptake, morphogenesis, ripening, etc. Objective: This study aimed to evaluate the effect of gibberellic acid, indole butyric acid, and methanol as plant growth regulators on morpho-physiological and phytochemical features in Thymus vulgaris L. Methods: The farm...
