Mechanization and simplification are inevitable trends in agriculture production to decrease input demands and simultaneously improve resource use efficiency. Dry direct-seeded rice is a resource-saving cropping system and has been considered as a replacement for traditional transplanted rice. However, the poor establishment of dry direct-seeded early rice, primarily induced by chilling stress,...

ABSTRACT- Seed germination and early seedling growth are critical stages for plants establishment and production, particularly under salinity conditions. Exogenous application of silicon (Si) can enhance germination as well as seedling growth. In this experiment, the effect of priming with Si (0, 0.75, 1.5 and 2.25 mM sodium silicate) on seed germination and seedling growth under NaCl (0, 100 a...

this research evaluated the effects of gibberellin (ga3) and abscisic acid (aba) on emergence capability, rate of emergence, vigor index and some physiological characters of chickpea seedling (cicer arietinum l.) in a field experiment (as split) under dry and irrigated conditions. seeds were primed with 0, 50, 100 and 150 ppm of each phytohormones. examined chickpea cultivar was azad. the resul...

Rice belongs to tropical and subtropical environments and is extremely sensitive to chilling stress particularly during emergence and early stages of seedling development. Seed priming can be a good approach to enhance rice germination and stand establishment under chilling stress. The present study examined the role of different seed priming techniques viz., hydropriming, osmopriming, redox pr...

Sweet pepper (Capsicum annuum L. CV. Keystone Resistant Giant #3) seeds were imbibed (primed) in salt solutions to determine a) what concentrations would inhibit radicle emergence and b) the influence this delay in radicle emergence would have on subsequent germination. Seeds were primed for 17 days at 23C in petri dishes with KNO3, KCl, NaCl, K2SO4, Na2SO4, 1 NaCl: 1 CaCl2 (mol/mol), Ca(NO3)2,...

The species of Taverniera cuneifolia belonging to the family of legominoseae is a perennial species usually growing in the south of Iran. The objective of this study was to evaluate the effects of the drought stress and seed priming using acid ascorbic (AsA) on seed germination of Taverniera cuneifolia in laboratory and seedling morphological traits in greenhouse conditions. This study was cond...

A series of seed priming experiments were conducted to test the effects of different pretreatment methods to seed germination, seedling growth, and seed yield traits in maize (Zea mays L.). Results indicated that the seeds primed by gibberellins (GA), NaCl, and polyethylene glycol (PEG) reagents showed a higher imbibitions rate compared to those primed with water. The final germination percenta...
