seed dormancy is a genetically inherited trait whose intensity is modified by the environment during seed development and maturation. in order to study the effect of harvest time on the seed quality and optimum time of sowing to obtain good quality seeds, freshly threshed seeds of ten diverse rice genotypes harvested from six environments were evaluated for seed dormancy and seedling vigour ind...

in order to evaluation the effect of drought stress on germination indices and early seedling growth of medicinal herb dill (anethum graveolens l), an experiment was conducted in the agricultural laboratory of urmia payam noor university in 2015 as a randomized complete block design with four replications. treatments were five levels of drought stress (0, -1, -2, -3 and -4 bar induced by polyet...

Information on desiccation sensitivity of Euterpe edulis seeds under two drying rates is presented. The sensitivity was studied during the course of germination and normal germination. The water content was evaluated for both seeds and embryos. Results showed the following: (a) For both drying treatments and for both germination and normal germination, desiccation sensitivity values were higher...

Among the promising medicinal plants, Nigella sativa, also known as Black seeds and Black cumin, has been called the “Blessed Seed” for its miraculous curing ability. Present study has been carried out to evaluate anti-oxidant properties at different germination stages of seeds of Nigella sativa. The level of antioxidant enzymes, SOD and CAT decreased gradually in the samples from first day to ...

Wheat (Triticum aestivum L.) is one of the oldest cultivated crops and the second most important food crop in the world. Seed germination is the key developmental process in plant growth and development, and poor germination directly affects plant growth and subsequent grain yield. In this study, we performed the first dynamic proteome analysis of wheat seed germination using a two-dimensional ...

Long non-coding RNAs(lncRNAs) are longer than 200 nucleotides in length, which largely exist in organism and have various biological functions. AtR8 RNA is a lncRNA transcribed by RNA polymerase III in Arabidopsis. Northern blot analysis indicates that AtR8 RNA is abundant during seed germination. AtR8 RNA partial deletion reduces seed germination under normal culture condition. SA treatment in...

-1,3-Glucanase ( Glu) expression in seeds plays important roles in the regulation of seed germination, dormancy and in the defence against seed pathogens. A thick -1,3-glucan layer is typical for the seed envelope of cucurbitaceous species, confers seed semipermeability and is degraded during germination. In many species with coat-imposed dormancy, the seed envelope confers a physical constrain...
