Over the course of 2 days, top researchers in the fields of bacterial spore biology and computational biology discussed approaches to determine the cause of spore germination heterogeneity. Biological and mathematical data gaps were identified, and experimental approaches and computational strategies for modeling spore germination were presented and evaluated. As a result of these interactions,...

This study was carried out to determine effects of different durations (20, 40, 60 days and control) of cold stratification treatments on seed germination and to overcome dormancy in seeds of twelve different drought tolerant plants. The species used in this study were Arbutus andrachne L., Cistus creticus L., Colutea armena Bois. Huet., Cotinus coggygria Scop., Cotoneaster numullaria Fisch. an...

A method is described to determine germination by blue-light excited red fluorescence in the positively photoblastic spores of Dryopteris paleacea Sw. This fluorescence is due to chlorophyll as evidenced from 1) a fluorescence-emission spectrum in vivo, where a bright fluorescence around 675 nm is obtained only in red light (R)-irradiated spores and 2) in vitro measurements with acetone extrac...

Patterns of accumulation and ontogenetic relationships among proteins of cotton (Gossypium hirsutum L.) seeds were examined between 10 days postanthesis and maturity (56 days). Total and extractable nitrogen contents were determined; alkali- and water-soluble proteins were assayed quantitatively and electrophoretically. Two alkali-soluble proteins present in the electrophoretogram of mature emb...

abstract- this experiment was carried out during the growing seasons of 2010 and 2011 at the agricultural research farm of bu-ali sina university, to study the effect of weed competition on subsequent germination and seed vigour of chickpea. 12 weed interference durations were evaluated in a randomized complete block design with three replications. experiments consisted of two sets of treatment...

Vetiver grass (Vetiveria zizanioides L.) is widely used for soil and water conservation, land management. In practice, all vetiver seedlings are propagated via ramets or tillers, which cannot meet the market demand would also destroy original habitat. Most genotypes flower but do not produce seeds. A wild ecotype of originated in southern China fertile, rate seed germination very low. This stud...

Paeonia ostii ‘Feng Dan’ is an economically important, multipurpose woody plant in terms of its medical, ornamental, and oil values; however, there a noticeable contradiction between the increasing demands lack excellent germplasm resources because traditional breeding propagation approaches. In vitro embryo culture attractive option for this issue. This study presents protocol immature P. Dan’...

Fruit maturity for seed production can occur at various times because of the continual flowering pepper plants. Accordingly, seeds with different are acquired as fruits collected in a single harvest. Immature obtained this harvest may lead to decrease quality lots. Therefore, research aimed evaluate influence four endophytic bacteria strains (Pseudomonas fluorescens strain L5b, Pseudomonas gess...
