Seed Priming Enhances the Performance of Late Sown Wheat (Triticum aestivum L.) by Improving Chilling Tolerance

Abstract

In rice–wheat systems, late sowing of wheat is the major reason of low yield. This yield reduction is principally due to lower and erratic germination, and poor crop establishment because of low temperature prevailing. The present study was conducted to explore the possibility of improving late sown wheat performance by seed priming techniques. Seed priming strategies were: on‐farm seed priming, hydropriming for 24 h, seed hardening for 12 h and osmohardening with KCl or CaCl2 for 12 h. Seed priming improved emergence, stand establishment, tiller numbers, allometry, grain and straw yield, and harvest index. However, seed priming techniques did not affect plant height, number of spikelets, number of grains and 1000 grain weight. Osmohardening with CaCl2 gave more grain and straw yield and harvest index compared with control and other priming treatments, followed by osmohardening with KCl and on‐farm seed priming. Improved yield was attributed principally to better stand establishment and improved number of fertile tillers. Seed priming techniques can be effectively used to improve the performance of late sown wheat.

Evaluation of seed priming and coating on emergence, yield and yield components of bread wheat (<i>Triticum aestivum</i> L.) in Northwest Ethiopia

“…One of the most common adaptive measures that have been adopted by many countries is pre-farming seed treatments such as seed priming and coating (Hoseini et al, 2013). Seed priming is a technique by which seeds are partially hydrated to a point where germination-related metabolic processes begin but just prior to germination where radical emergence does not occur (Farooq et al, 2008). Several investigations confirmed that seed priming has many benefits including early emergence, good stand establishment, deeper roots, uniformity in emergence, initiation of reproductive organs, better competition with weed, early flowering and maturity, resistance to environmental stresses (Amin et al, 2012).…”

Seed Priming Improves the Performance of Late Sown Spring Maize (Zea mays) Through Better Crop Stand and Physiological Attributes

“…Seed priming is used to lessen emergence time, harmonize germination, enhanced germination rate and crop establishment in a lot of horticultural (Bradford, 1986) and field crops like wheat, rice and maize Farooq et al, 2008;Rehman et al, 2011). Harris et al (1999) demonstrated that on-farm seed priming clearly enhanced early vigor and seedling establishment of maize, upland rice and chickpea, resulted in accelerated development, earlier flowering and maturity and high yields of these crops.…”
