The effects of magnetic treatments on germination and the initial growth stages of triticale seeds have been studied. Germination and growth tests were carried out under laboratory conditions by exposing triticale seeds to 125 mT for different times (1, 10 and 20 min, 1 and 24 hour). The rate of germination was assessed by determining the mean germination time (MGT) and time required to germina...

Extend abstract Introduction: Guava (Psidium guajava L.) is one of the most important fruit crops of tropical and subtropical regions. Guava (Psidium guajava L.) can be propagated by seed, layering, grafting, cutting or tissue culture. Propagation by seed is used for the production of seedlings usable in breeding programs or rootstock production for grafting. Guava seeds germinate poorly and u...

In addition to seed quantity, study of seed quality of crop in conditions of competition could be profitable for seed procurement from field. For this purpose, produced seeds of four wheat cultivars (Sayson, Alvand, Chamran and Sepahan) in interference with deferent densities of feral rye (0, 20, 40, 60 and 80 plants m-2) were harvested. In laboratory, of each field unit, 50 number of wheat see...
