—It is important to identify rapid and accurate methods for assessing hardwood seedling quality and physiological status. Evaluation of electrolyte leakage (EL) from plant tissues is promising for this purpose. It has successfully predicted the physiological status of conifer seedlings and has been used experimentally on European hardwood species. Three species of hardwoods, northern red oak (Q...

to study the effects of chilling on dormancy breaking and the increased germination characteristics of nepeta (germination percent and speed, seedling length, vigor index, wet and dry weight), a factorial experiment in a completely randomized design with 4 replications was implemented in a laboratory in 2014. factor a was the chilling treatment in three levels (control, one-month and two-month ...

In order to investigating the effect of different tobacco cultivars residue on germination and seeding growth of soybean an experiment was conducted at laboratory and glasshouse in college of Sari Agricultural Sciences and Natural Resources University during 2007 as a factorial based on completely randomized design with four replications. Extracts of root and shoot from two different types of t...

Germination characteristics, early seedling growth and seed metabolic efficiency of four wheat genotypes (BARI Gom 28, BARI 29, BAW 1177 ESWYT 29) were evaluated under 15% polyethylene glycol (PEG-6000) induced osmotic stress (-3 bar). characteristics (germination rate, co-efficient germination vigor index), shoot root length, dry weight, decreased by PEG than control treatment. But the degree ...

Peanut (Arachis hypogaea L.) seeds were germinated to investigate the effect of fermentation period oak tree sawdust on germination viability and seedling characteristics. Its rate, weight, length, total vigor index assessed. The sown in fermented for 0, 30, 45, 60 days. rates significantly different. 45-day produced heaviest biomass weight (4.6 g) with longest true leaf (1.7 cm) hypocotyl (3.4...

In plants, source-sink communication plays a pivotal role in crop productivity, yet the underlying regulatory mechanisms are largely unknown. The SnRK1A protein kinase and transcription factor MYBS1 regulate the sugar starvation signaling pathway during seedling growth in cereals. Here, we identified plant-specific SnRK1A-interacting negative regulators (SKINs). SKINs antagonize the function of...
