this study evaluated direct drilling planters used for wheat cultivation in khorasan-e razavi province. a randomized complete block design with three replications was used. the treatments were direct drilling of wheat plants into wheat residue using the following direct planters: (1) sfoggia (13-25), (2) baldan (spd3000), (3) tondar (spd 2500), (4) semeato (shm 11/13). the parameters measured w...

Efficient seed germination and rapid and uniform seedling emergence are important in commercial agriculture. Therefore, the use of strategies to improve germination and seedling establishment is necessary for increasing productivity. Hydropriming has been suggested as a simple pre-germination strategy to improve seed performance. In this study, the effects of different durations of hydropriming...

to better understand seed priming that improve seed germination and seedling uniformity, we examined the physiological role of osmopriming in germination of bread wheat (triticum aestivum l.) seed embryos by a proteomic approach. for this purpose, we used two systems. the first system consisted of osmo-primed seeds by peg 6000 at -0.8 mpa at 15?c for 24 hours, followed by air drying at 15?c, an...

(How and why to measure the germination process?). In the last two centuries, papers have been published including measurements of the germination process. High diversity of mathematical expressions has made comparisons between papers and some times the interpretation of results difficult. Thus, in this paper is included a review about measurements of the germination process, with an analysis o...

The use of seeds with high physiological quality allows rapid growth and establishment seedlings in the field to be obtained. Therefore, accuracy information obtained during determination is great importance. objective was generalized linear models, investigating which link function (Probit, Logit Complementary log-log) suitable predict T50 uniformity germination soybean corn seeds. To perform ...

Abstract: Two experiments were conducted to study the impact of salt stress and salicylic acid (SA) on seed germination and plant growth of maize (SC704) under field conditions in the city of Kerman in 2010. For germination experiment, SA seed pretreatments included control, water soaked, SA soaked in 0.1 and 0.2 mM for 24 hours and salt treatment included control, 40 and 80 mM NaCl. All see...
