It was evaluated the damage caused by Bruchus pisorum on the germination ability of pea forage cultivars. Result of damage in seeds with parasitized larva was a significant decrease of the germination by 16.4% percentage points, the length and weight of primary radicle by 16.8 and 24.5%, the length and weight of plumule by 12.3 and 14.1%, the vigor index of primary radicle and plumule by 32.5 a...

If the hard seed (seed that is viable but has an impervious coat) content of legumes greater than 20%, scarification should be considered. Scarification nicking coat to allow moisture penetrate [1]. This type treatment before sowing great importance, as it increases yield fodder plants by reducing rate rare and expensive seeds, cost sowing, accelerating germination, increasing percentage germin...

abstract seed deterioration of seed is one of the most important limiting or even hindering factors in germination. the main purpose of this study was to determine the effects of salicylic acid and gibberellic acid hormonal on improvement and prevailing seed deterioration in two sesame cultivars. this studywere carried out at the department of agronomy and plant breeding seed laboratories of co...

Denrostellera lessertii (Thymelaceae) is a native plant of Iran, which grows in limited area of Iran. So far, different groups have reported the anticancer products of many species of this family. The antitumor and anti-metastatic properties of D.lessertii have also been well worked out in our group and the most active component, 3-Hydrogenkwadaphnin has been purified and its chemical structure...

Arsenic (As) contamination is an important environmental consequence in some parts of salinity-affected South (S) and South-East (SE) Asia. In this study, we investigated the individual and combined phytotoxicity of arsenic (As) [arsenate; As(V)] and salinity (NaCl) on early seedling growth (ESG) of saline-tolerant and non-tolerant rice varieties. Germination percentage (GP), germination speed ...
