Although Azospirillum spp. are considered to be important plant growth promoting bacteria, their possible effects on germination and vigor of aged lettuce seeds has not been previously evaluated. In fact, there is a paucity of published data about inoculation effects on seed germination. The aim of this work was to evaluate seed quality of oneyear aged lettuce (Lactuca sativa L. cv. Crimor INTA...

During seed maturation and germination, major changes in physiological status, gene expression, and metabolic events take place. Using chlorophyll sorting, osmopriming, and different drying regimes, Brassica oleracea seed lots of different maturity, stress tolerance, and germination behavior were created. Through careful physiological analysis of these seed lots combined with gene expression an...

Osmopriming with PEG has potential to improve seed germination, seedling emergence, and establishment, especially under stress conditions. This research investigated germination performance, seedling establishment, and effects of osmopriming with PEG on physiology in sorghum seedlings and their association with post-priming stress tolerance under various soil moisture stress conditions. Results...

Priming is one of the most common methods of improving seed quality. The aim of this experiment was to study the effects of hydroand osmopriming on the germination, vigour and hydrolytic enzymes (α-amylase, β-glucosidase, exopeptidase and lipases) activity of zinnia (Zinnia elegans Jacq.) seeds. Seeds of three cultivars: Jowita, Kirke and Orys, and Z. elegans fl.pl., a mixture of cultivars (Mix...


 setacea seeds without aril, were submitted to pre-germination treatments: T1(control); T2 (pre-soaking in Promalin® solution [gibberellin (GA4+7) + N-(phenylmethyl)-1H-purine 6-amine (6-benzyladenine) both at a concentration of 18.8 g.L-1] bainMarie, 45 °C/20 min.; T3 (osmopriming with KNO3 2.6g.L-1 H2O, 25 °C/1 day, aeration); T4 2.6g.L- 1 °C/2 days, T5 (T3 followed by T2) and T6 (T4 T2...

Seed priming has been suggested to improve germination performance under temperature or water stress. The objective of this study was to develop an optimal osmopriming protocol for spinach (Spinacia oleracea L. cv. Bloomsdale) seeds and examine its effect on the germination performance at suboptimal and supraoptimal temperatures, and under water stress. Standard germination tests at optimal ger...

Tohum kalitesi ve gücü (vigor) sebze üretiminde verim kaliteyi etkileyen en önemli faktördür. Çabuk bozulma özelliği gösteren pırasa tohumlarının (Allium porrum L. cv. İnegöl) çıkış gücünü iyileştirmek için tohumlar -1.0 MPa osmotik potansiyele sahip PEG6000 and KNO3 çözeltilerinde (osmopriming) suda (hidropriming) farklı sürelerde (6, 12 24 saat) tutulmuştur. Daha sonra oda koşulları sabit 30°...
