Quality of seeds of three cultivars (IPSA Seem-2, BU Seem-3 and IPSA Seem5) of lablab bean (Lablab purpureus L. Sweet) collected from crops planted in three different dates (15 May, 15 July, and 15 September 2003) was assessed in respect of different parameters. The maximum percentage of seeds of cv. IPSA Seem-2 was germinated (95.67) whereas, BU Seem-3 had the maximum electrical conductivity (...

Soil salinity is an increasing environmental stress on crops in most areas of Iran since farmers use underground saline water for irrigation. In order to investigate the effects of salt stress on germination and seedling growth of safflower (Carthamus tinctorius L.), an experiment was conducted at two stages (germination seedling growth), using four levels of NaCl salinity (0, 5, 10, 15 ds/m), ...

Soil and water salinity substantially constrain crop and biomass production. To investigate the changes in morphological parameters of lisianthus (Eustoma grandiflorum) cultivars under CaCl2 salinity conditions a greenhouse experiment was conducted. Cultivars namely, ‘Champagne’ (C1), ‘Lime Green’ (C2), ‘Blue Picotee’ (C3) and ‘Pure White’ (C4), were subjected to salt stress (0–30 mM CaCl2) in ...

Root traits influence the amount of water and nutrient absorption, and are important for maintaining crop yield under drought conditions. The objectives of this research were to characterize variability of root traits among spring wheat genotypes and determine whether root traits are related to shoot traits (plant height, tiller number per plant, shoot dry weight, and coleoptile length), region...

in the present study, effect of five isolates of trichoderma harzianum on growth parameters of tomato was carried out as cr design with six replications under greenhouse conditions. the concentrations 0.5%, 1% and 1.5% inoculums per pot were used. plant length, shoot and root fresh/dry weight, number of leaves and stem diameter as growth parameters were measured. the results showed that isolate...

     Mutations induced by gamma irradiation are part of improving some important agronomic traits in crops.  Identifying the optimal mutagenic dose is considered to be the most crucial step in trials and generating mutated genetic materials. The goal of this study was to evaluate the effect of different doses of gamma ray (0, 150, 200, 250 and 300 Gy) on some plant early stages traits and bioch...

In this research the effect of four concentrations of nickel and copper (25, 50, 100, and 200 µM) on root and shoot length, fresh and dry weight, leaf surface, and photosynthetic pigments (Chlorophyll a, b and carotenoids), sugar, malondialdehyde, hydrogen peroxide content and antioxidant enzyme activity (CAT and APX) in Okra plants were evaluated. The results showed that in those plants which ...
