turfgrass that support the popular hypothesis that dehydrin accumulation is positively correlated with dehydration tolerance. Hu et al. (2010) reported that accumulation of 31- and 40-kDa dehydrins may contribute to drought tolerance in bermudagrass
). Rootstocks have since been developed for other traits that include nematode resistance, lime tolerance, salt tolerance, tolerance of saturated soil, and influence on scion vigor and fruit maturity ( Galet, 1998 ; Pongrácz, 1983 ). Drought tolerance can also

( Tardieu and Simonneau, 1998 ). Although E. spectabilis is a native plant, its higher tolerance to moderate water stress than M. sinensis does not necessarily imply that native grasses outperform nonnatives in drought situations. Water use and drought
watermelon germplasm with drought tolerance properties is needed for the development of drought-tolerant watermelon varieties. The National Engineering Research Center for Vegetables (NERCV) and the beijing academy of Agriculture and Forestry Science
during drought stress. Several studies have indicated that proline content increases during drought stress, and proline accumulation is associated with improvement in drought tolerance in tall fescue and other plants ( Seki et al., 2007 ; Zhang et al
). Evidence of drought conditions has been reported in these areas ( Escalante et al., 2016 ), which could limit cowpea production; however, little has been done toward advancing breeding programs for drought tolerance in cowpea compared with other legumes
times less than the average yield in the United States, where water is abundant ( Agbicodo et al., 2009 ). Research has shown that there is a considerable difference among cowpea varieties in drought tolerance ( Mai-Kodomi et al., 1999 ). Many cowpea
Drought stress damage in plants is characterized of leaf dehydration, and therefore, increasing the capacity of water retention in leaves or improving leaf tolerance to dehydration to maintain cell turgor is critically important for plant survival
availability is limited and extensive irrigation is not practical. Therefore, improvement of drought tolerance of turf and forage grasses is becoming increasingly important to minimize effects of drought on the plants and to enhance water conservation
