“…It is reported that water stress acts by decreasing percentage and rate of germination (Delachiave and Pinho, 2003). The present results also indicate that C. nitidissima seeds cannot tolerate short-termed drought-stress, which is the important reason why this plant only grows in forests of wet shady valleys or along streamside on mountains or hills.…”

“…in maize (Martinielio & Lorenzoni, 1985;Lorens et al, 1987;Grzesiak, 1990;Grzesiak et al, 2012), wheat (Winter et al, 1988;Reynolds et al, 1998;Paknejad et al, 2007), rape seed (Richards & Thurling, 1978), oat (Larsson & Go'rny, 1988), coconut (Gomez et al, 2008) and triticale (Royo et al, 2000;Grzesiak et al, 2012). Unusual dry weather conditions adversely affect germination and seedling growth rates thus enhancing cell elongation sensitivity to damages induced under stressed conditions (Taylor et al, 1982;Delachiave & Pinho, 2003;Hamayun et al, 2010a). Deleterious effects of water stress have been reported in different crops such as tomato (Ragab et al, 2007), soybean (Sakthivelu et al, 2008;Hamayun et al, 2010b), corn (Khodarahmpour, 2011) and citrus (Ben-Hayyim, 1987).…”

Maize is susceptible to drought stress, especially during germination. The experiment of seed germination and seedling growth of two maize varieties under different concentration of mannitol solution was carried out. Four mannitol concentrations were set: 0, 200, 400 and 600 mM, and the corresponding solution osmotic potential was: 0, -0.49, -0.99, and -1.49 Mpa. Results indicated that Zhengdan958 germinated more quickly and in greater numbers than Liansheng15. The germination rate, germination potential, shoot and root fresh weight, shoot and root length of two maize varieties both decreased under drought stress, but they decreased more in Liansheng15 than in Zhengdan958. However, the germination and vigor index of Zhengdan958 were obviously higher than that of Liansheng15 under the stress of 200, 400 and 600 mM mannitol. These results showed that the drought resistances of Zhengdan958 was higher than that of Liansheng15 by having more powerful root system and higher osmotic adjustment ability.

A pot experiment was carried out in completely randomized design (CRD) having three replications to screen out six maize (Zea mays L.) hybrids viz; FH-810, 32-F-10, FH-782, 32-B-33, YH-1898, Monsanto-6525, R-2315 and R-3304 for drought tolerance. The study was carried out with objective to screen hybrids, when exposed to drought on the early phase of their vegetative growth. The moisture treatments comprised of 100% field capacity (FC), 75% FC and 50% FC. The results exhibited that all these hybrids varied substantially in their stability against drought tolerance. However, the results pertaining to interaction of maize hybrids with three moisture levels of 100% FC, 75% FC and 50% FC revealed that 32-F-10 performed comparatively better in contrast to other maize hybrids in plant height (79.74 cm, 47.02 cm and 41.65 cm), leaf area per plant (865.10 cm 2 , 405.7 cm 2 and 178.60 cm 2 ), relative water contents (81.23%, 69.79% and 65.98%), at 100%, 75% and 50% FC, respectively, while YH-1898 hybrid produced lowest values of these attributes in almost all water levels. However, a better stomatal conductance (gs), photosynthetic rate (A) and transpiration rate (E) were exhibited by 32-F-10 while YH-1898 revealed least gas-exchange values among all hybrids. The experimental results revealed that under drought conditions 32-F-10 performed best than all other maize hybrids and could be used for further investigation to screen out other drought tolerant-maize hybrids for maximum production.
