detopping in some plants reduces vegetative growth and increases transporting of photosynthate materials to specific sinks such as seeds. to study the effects of detopping removal and plant density on yield and yield components of faba bean (vicia faba l.), an experiment was carried out as a factorial arrangement based on a randomized complete block design with three replications at farm resear...
abstract. seeds or plant organs are usually used as the materials for the long-term cryopreservation. the aim of this study is to investigate the possibility of seed cryopreservation of lilium ledebourii (baker) boiss. as an endemic and endangered species because of genetic erosion. to evaluate seed potentials for the cryopreservation, four treatments including vitrification, 30% glycerol, desi...
domestication of animals has had some important effects on physiology, morphology, behavior and well-being of domesticated animals. conscious or goal directed selections on animals for increasing their productions has accelerated the rate of the changes, leading to some well-being defections. this paper notes some aspects of animal domestication in context of genetic science. then explains how ...
Background: Given the role educational system, it is necessary to most desirable design and implements activities. Internal evaluation is process in which members of the department said the group's objectives and their performance are judged and then reviewed their role and for better performance, essential steps to take.The purpose of this study was the internal evaluation of Physiology Depart...
This research was carried out with the aim of dormancy breakage and seed germination improvement in mature and immature seeds of T. rubra subsp. caucasica form angulata. The seeds were collected from middle altitude (500 a.s.l.) forests of Chamestan, north of Iran. Mature and immature seeds with pericarp were treated as 1) cold stratification (without pretreatment), 2) imbibed with NaOH (30%)+c...
Seed’s dormancy is considered as one of the effective factors in seeds germination and consequently in the growth of seeds of many plant species. Shortening the dormancy period and enhancing the germination percentage in fruit types could be a valuable strategy for the seed researchers and plant nurseries. In this research the seeds of mature fruits of different almond cultivars including late-...
to answer this question that if osmopriming improve germination indices in salinity-affected seeds of pinus eldarica medw., a factorial experiment in randomized completely design was carried out with three replications. osmotic treatments were applied in 5 levels (-2, -4, -6 and -8 bar for 72 hours and non-primed) by polyethylene glycol (peg) and salinity treatments in 8 levels (0, 40, 80, 120,...
Background and objectives: Sesame (Sesamum indicum L.) seeds have been a well-known oil crop in the world for many centuries. Lignans are functionally important compartments of sesame. Sesamin and sesamol are the main sesame lignans, which have recently shown various activities with health benefits, like anti-oxidative, anti-proliferative, anti-atherosclerotic, anti-in...
Germination of strawberry seeds from self- and cross pollination of 4 commercial cultivars were evaluated under mist and in vitro cultures. The study was conducted in McGill University in Quebec, Canada, during 1994 and 1995. Self-pollination of Chambly and Redcoat cvs., and cross pollination of Oka × Chambly as well as Redcoat × Veestar and their reciprocals were used. At maturity, fruits were...
