Ammodendron persicum (Bunge & Boiss.)is a desert shrub specie which grows on some sand dunes and sandy areas of South Khorasan and Sistan-va-Baluchestan provinces in east of Iran. Low distribution and narrow ecological range have put this species under threat. In order to evaluate the possibility of long-term preservation of A. persicum seeds in cryogenic conditions (-196°C), the seeds of speci...

Rare earth elements (REEs) enriched fertilizers have been commonly used in China since the 1980s, thus inducing a growing concern about their environmental impact in agriculture. In this work, the effect of some light REEs nitrate mixture and La(3+) nitrate on seed germination, seedling growth and antioxidant metabolism in Triticum durum was investigated with the aim of clarifying the potential...

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 ...

Roegneria kamoji Ohwi (Poaceae), a wild relative plant of wheat which is widely distributed across China, has become dominant and problematic weed in fields some regions. We have previously confirmed that R. highly tolerant to foliar-applied acetyl-CoA carboxylase (ACCase) acetolactate synthase (ALS) inhibitors (Triticum aestivum L.). The sensitivity pre-emergence (PRE) herbicides the basis fen...

This study aims to determine the effect of pre-emergence application herbicide metsulfuron methyl on soil mixed with rice husk biochar germination weeds. used a factorial completely randomized design (CRD) two levels (0 gr/ha and 300 gr/ha) four (0%, 5%, 10%, 15% total weight planting medium). The parameters observed were number weeds, wet dry results showed that interaction had no significant ...

Aim. To investigate the variability of alpha-amylase isoenzymes in soft wheat varieties Ukrainian selection, created by breeding institutions located different climatic zones (Forest Steppe and Steppe). Methods. Isoenzymes were detected electrophoretic protein separation a polyacrylamide gel. The fall number on «Falling Number 1700» was determined. Results. For representative assessment distrib...

Germination experiments with specific germination mutants of Bacillus subtilis, including a newly isolated mutant affected in pressure-induced germination, suggest that a pressure of 100 MPa triggers the germination cascades that are induced by the nutrient germinant alanine (Ala) and by a mixture of asparagine, glucose, fructose, and potassium ions (AGFK), by activating the receptors for alani...
