Seed dormancy-breaking and germination requirements of
Dormancy breaking and germination requirements were investigated in seeds of Ferula ovina and Ferula gummosa. Seeds of rather species were collected from north and eastern-north rangelands of Iran. Seeds of each of the species were subjected to different treatments including various levels of GA3, chilling and combination of GA3 and chilling (GA-chilling). In contrast to treated seeds, non-trea...
متن کاملMaturating, Enlarging and Breaking Dormancy of In Vitro Lilium Bulblets
One of the most effective ways to propagate Lilium is by using tissue culture techniques, preferably through bulblet production. In addition to the surviving percentage of Lilium bulbs after transplantation, the small size of in vitro bulblets compared to commercial bulbs and bulblets‟ dormancy are the most important constraints to commercializing Lilium micropropagation. Different concentratio...
متن کاملa study of seed dormancy and dormancy breaking factors during after-ripening period of barley genotypes (hordeum vulgare l.)
to study seed dormancy and the after-ripening period in barley genotypes (57 dutch genotypes and two iranian cultivars (gorgan and valfair)), an experiment of randomized complete block design (two replications) was conducted at the research farm of collage of agriculture and natural resources, university of tehran in 2004-2005. in the growing stage of zgs92, panicle was collected. the percentag...
متن کاملA STUDY ON SEED GERMINATION OF AVENA LUDOVICIANA AND THE EFFECTIVE FACTORS IN SEED DORMANCY BREAKING
Wild oat has two seeds in a spikelet that they have different physiological behavior in regard of seed germiantion. The upper seed of spikelet is smaller and has deeper dormancy than the lower seed. The range of temperature for germination is 5˚C to 25 ˚C and optimal temperature is 15˚C. Both kinds of seeds showed the more germination rate in low temperatures so that 5 and 10˚C are better...
