Investigating the Effects of Natural and Artificial Seed Deterioration on Reactive Oxygen Species, Antioxidant Enzymes, and Seed Germination Characteristics in Local and Improved Rice (Oryza sativa) Cultivars Derived from the Farms in Guilan Province
Extended abstract Introduction: Seed deterioration is associated with oxidative stress and uncontrolled accumulation of reactive oxygen species. Seeds have a group of enzymatic and non-enzymatic antioxidants that protect them against reactive oxygen species and help maintain seed vigor and support seed germination processes. The response of different cultivars to seed deterioration is differen...
متن کاملاثر پیش‌تیمارهای مختلف بر صفات جوانه‌زنی و رشد بذرهای برنج (Oryza sativa) در مقایسه با نانوذرات نقره در طی تنش خشکی
The present study sought to compare the effect of seed priming by hydropriming, ascorbate and calcium chloride (CaCl2) versus different concentrations of silver nanoparticles on two Iranian rice cultivars (Hashemi and Shiroodi) under drought stress. The experimental design, which was factorial, was completely randomized. The first factor was control (without priming), hydro-priming, 20 mg.L-1 c...

In order to evaluate the response of rice genotypes to salinity stress at germination stage an experiment was conducted as a factorial experiment in a completely randomized design with three replications in Biotechnology La of Sari Agricultural Sciences and Natural Resources University (SANRU). Sixteen rice genotypes were evaluated at four salinity levels (0, 40, 80 and 120 mM). The results of ...
متن کاملبررسی تحمل به شوری بوته‌های نسل F2 حاصل از تلاقی سه رقم برنج (Oryza sativa) در مرحله جوانه‌زنی
Salinity is one of the environmental stresses limiting rice cultivation. Evaluation of the tolerance and sensitivity of offsprings of segregated generations under salinity condition is one way of finding tolerant cultivars. In order to study the effects of salinity (80 mM NaCl) stress on the second generation offspring of crosses of three rice varieties (Dollars and Gharib with 304) and to comp...
متن کاملThe Effect of Climate Change on the Yield of Rice in the Rasht County
Given the climatic changes and threats to food security in recent years, they have have become a major issue in agricultural climatology. The present study aimed to investigate the status of agricultural climate suitable for the cultivation of rice in the light of the influential climatic conditions in the past. Given the effect of temperature and the amount of precipitations on rice growth and...
