To evaluate deterioration of oat seeds during storage, we analyzed oxygen radicals, antioxidant enzyme activity, proline content, and gene transcript levels in oat seeds with different moisture contents (MCs; 4, 16, and 28% w/w) during storage for 0, 6, and 12 months (CK, LT-6, and LT-12 treatments, respectively) at 4°C. The germination percentage decreased significantly with higher seed MCs an...

Differences in seed storage tolerance between soybean cultivars have been frequently observed. Thus, identifying compounds found them that may be related to these differences is necessary support the selection of with seeds better potential. Therefore, this study aimed evaluate changes viability and vigor during two environments, relating antioxidant activity, production reactive oxygen species...

Drought stress as an abiotic stress causes different biochemical and physiological responses in plants. To study changes in chlorophyll, total soluble protein and antioxidant activity due to drought stress, we conducted an experiment on five durum wheat varieties (selected from the Seed and Plant Improvement Institute in Karaj) at research greenhouse of Imam Khomeini International University in...

Drought stress is a serious threat to the germination of plant seeds and growth seedlings. Melatonin has been proven play an important role in alleviating stress. However, its effect on seed under drought conditions still poorly understood. Therefore, we studied effects melatonin rice physiological characteristics Rice were treated with different concentrations (i.e., 0, 20, 100, 500 μM) was si...

Changes in catalase (CAT) activity and in CAT isoform pattern and expression were investigated in developing sunflower (Helianthus annuus L.) seeds during desiccation on the mother plant and after artificial drying on the flowerheads. Seeds regularly desiccated during their development on the mother plant and reached mass maturity at c. 42 d after flowering (DAF). Freshly harvested seeds did no...
