anastrepha bezzii (diptera: tephritidae) larvae are common inside fruits of sterculia chicha (malvaceae) in minas gerais state, brazil. the seed dormancy and attack by a. bezzii of the native species s.chicha can be detrimental to seed germination and thus the natural spread of this plant. the objectives of the current study were to compare ecological observations of a. bezzii and s. chicha in ...
Micronutrients play a great role in the production of high quality seeds, especially in terms of germination. Therefore, providing seeds with sufficient amounts of these is an important consideration in seed production. The present study was conducted as two separate experiments in the Seed Laboratory of Yasouj University in 2015. In the first experiment, the sesame seeds (cv. Darab 1) obtained...
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-...
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...
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...
Seed deterioration is loss of seed quality, viability and vigor due to effect of adverse environmental factors. Many of our crops are reproduced through seeds, and throughout the world large quantities are produced, stored and transported. Seed ageing during storage may cause retardation of field establishment, and may eventually result in seedling abnormalities or even failure of emergence. Du...
dormancy of eastern dodder and african rocket seeds makes the controlof them very difficult in orchards and farms. in order to study the effective factors in dormancy breaking of these two weeds species, a factorialexperiment based on crd with three replications was conducted at the research laboratory of birjand faculty of agriculture in 2008 and 2009. treatments were: control, soaking in sulf...
This study was conducted to evaluate the effect of hydropriming and seed aging on germination and enzymatic properties of pinto bean under salinity stress as factorial based on a completely randomized design with four replications. Two groups of seeds (i.e., non-aged and aged seeds), two hydropriming treatments (i.e., hydro primed and unprimed seeds) and six salinity treatments (i.e., 0, 2, 4, ...
This study was conducted to study the effects of different priming methods on germination rate and percentage under salinity stress and to determine the stability of primed seeds. In order to accomplish this, three different experiments were conducted separately, including the experiment of water uptake, the experiment of salinity stress, and the experiment of storability of primed seeds. Primi...
in order to study of hydropriming and halopriming on germination and early growth stage of wheat (triticum aestivum l.) an experiment was carried out in laboratory of the department of agronomy and plant breeding, shahrood university of technology. seed treatments consisted of t1: control (untreated seeds), t2: soaking in distilled water for 18 h (hydropriming). t3: soaking in -1.2 mpa solution...
