Ecophysiological aspects of seed germination were investigated in four Mediterranean geophytes of the genus Muscari (Liliaceae): M. comosum (tassel hyacinth), M. neglectum (common grape hyacinth), M. commutatum and M. weissii. Experiments were performed at constant temperatures in the dark and under temperature and light conditions simulating those prevailing in nature during November–January, ...
This study was conducted to determine the effects of Artemisia sieberi extract (0.2%, 0.4%, and control) on germination, some morphological characteristics, photosynthesis pigments, and nutrients uptake of Peganum harmala. Results showed that the extract of A. sieberi had a significant effect on seed germination and morphological characteristics of P. harmala. The highest seed germination was c...
this research was conducted to evaluate the role of drought stress and planting dates on seeds vigour and seedling growth of produced seeds. the experiment was performed in the research field and seed technology laboratory of the department of agronomy and plant breeding, college of aboureyhan in pakdasht in spring 2008. five canola cultivars including licord, opera, modena, elite, sarigol (in ...
Seed germination plays an important role in determining the composition and regeneration of plant populations (Stipa breviflora). However, the influencing factors and strategies employed for seed germination in desert grasslands under grazing remain unknown. Therefore, in this study, the reproductive allocation, seed density, seed properties, and corresponding seed germination rates of S. brevi...
Germination is a biological process important to plant development and agricultural production. Barley and rice diverged 50 million years ago, but share a similar germination process. To gain insight into the conservation of their underlying gene regulatory programs, we compared transcriptomes of barley and rice at start, middle and end points of germination, and revealed that germination regul...
the dormancy characteristics and optimum conditions for seed germination of alstroemeria ligtu had not been explained. in vitro and in vivo alstroemeria (a. ligtu hybrid) seed germination tests were conducted in a randomized completely design at two different treatments (gibberellic acid (ga3) 0, 100, 200 and 400 mg/l with and without stratification in 5±1oc) in four replications. seeds were pl...
