introduction: b. campestris is an old plant that commonly grows in arid and semi-arid areas. it has mucilage in the epidermal cells of canola seeds, a considerable variation in growth form and characteristics across the many cultivars. these species have in general, a flat root without an elongated crown, with stems that typically grow 30 to 120 cm tall. the leaves are large, soft, smooth or so...

CRISPR-Cas (clustered regularly interspaced short palindromic repeats-CRISPR associated) systems allow bacteria to adapt to infection by acquiring 'spacer' sequences from invader DNA into genomic CRISPR loci. Cas proteins use RNAs derived from these loci to target cognate sequences for destruction through CRISPR interference. Mutations in the protospacer adjacent motif (PAM) and seed regions bl...

Priming of seed is intended to reduce the time germination through activation pre-germinative processes. Seed priming controlled hydration followed by a drying (dehydration) process. The physiological processes during (imbibition) were studied in detail tomato. In contrast, gibberellic acid changes dehydration phase not detail. We hypothesize that there would be change GA concentration process,...

Hydrogen peroxide was initially recognized as a toxic molecule that causes damage at different levels of cell organization and thus losses in cell viability. From the 1990s, the role of hydrogen peroxide as a signaling molecule in plants has also been discussed. The beneficial role of H2O2 as a central hub integrating signaling network in response to biotic and abiotic stress and during develop...

Seed priming is a technique which is potentially able to promote rapid and more uniform seed germination and plant growth as well. In this regards, the presowing effects of seed priming treatments were investigated on some physiological viz. seed germination, germination rate, radicle elongation, shoot elongation, radicle dry weight, shoot dry weight and vigor index. Seeds were subjected to two...

background and purpose: according to fao's report, lentil yield in iran is much lower than average yield in the world. this is due to low quality seedling production, low germination and emergence capacity, biotic and abiotic stresses and poor seedling establishment which was forced to looking for a way to enhance these components. seed priming is one of the strategy for increasing the rat...

Welsh onion (Allium fistulosum L.) is one of the important vegetable crops in China. However, the seeds of this crop are short-lived and their vitality tends to be easily lost in the course of storage. The present study was conducted to elucidate the effects of welsh onion seed priming with potassium nitrate (KNO3) on seed vigor and on other such related mechanisms during twelve months of stora...

Objective: To evaluate the effect of chemical stimuli on germination and seedling growth of Caper (Capparis Spinosa) under drought stress. Methods: Factorial experiment in a completely randomized design with four replicates per treatment were performed. First factor of priming include three levels of acetylsalicylic acid (300, 200 and 100 mg/L), gibberellic acid levels (500, 250 and 12...

Seed priming is a commercially successful practice, but reduced longevity of primed seeds during storage may limit its application. We established a series of experiments on rice to test: (1) whether prolonged storage of primed and non-primed rice seeds for 210 days at 25°C or -4°C would alter their viability, (2) how long primed rice seed would potentially remain viable at 25°C storage, and (3...
