Effects of late-terminal drought stress on seed germination and vigor of barley (Hordeum vulgareL.)

Abstract: Late-terminal drought stress during grain filling has recently become more common in the semi-arid Mediterranean region, where barley (Hordeum vulgare L.) is grown as an important winter cereal crop. Little information is available in the literature about the effect of late-terminal drought stress on seed germination and vigor of barley. The objective of this experiment was to study the effect of late-terminal drought stress on seed germination and vigor of barley as estimated by the germination after accelera… Show more

“…Similarly, a role of ABA in seed filling under terminal drought was also shown by Seiler et al (2011) and Govind et al (2011). But terminal drought stress had no effect on the germination of barley seeds, but reduced germination was noticed after the accelerated aging test (Samarah and Alqudah 2011). Worch et al (2011) monitored and mapped the expression patterns of drought stress-regulated genes in barley during plant ontogeny, and the location of these genes was incorporated into barley SNP linkage map.…”

“…Higher air temperatures during period April -July (anomaly + 1.0 °C in average) increased the vigour significantly (r = 0.741*). Samarah and Alqudah (2011) studied the influence of late-terminal drought stress during grain filling on the germination and vigour of barley. Stress during the grain-filling stage had no effect on the standard germination test, but it decreased the seed vigour, results that are similar to our results, indicating a positive influence of a high temperature during ripening and a negative influence of high precipitation on the vigour.…”

“…Withholding irrigation at eight-leaf and flowering stages did not reduce germination of sorghum. Also seedling growth rate was not significantly affected by irrigation levels (Younesi and Moradi, 2009). The reduction in seedling growth under water stress was expected because the growth rate of plant cells and the efficiency of their physiological processes are highest when the cells are at maximum turgor (Achakzai, 2009, Achakzai andBazai, 2007).…”

Other researchers reported that drought stress during seed development reduced seed vigor but had no effect on seed germination (Fougereux et al, 1997, Samarah andAlqudah 2009). The yield of viable and vigorous seed is an important goal for sorghum seed producers and farmers.…”
