| Referencing to literatures, this paper summarized approaches in identifying drought-resistance traints of wheat and external morphological characteristics of drought-resisting wheat. Additionally, this paper summarized the research progress on coleoptile length, chlorophyll content and chlorophyll fluorescence dynamics, osmotic adjustment, water use efficiency, stable carbon isotopes, drought resistance identification evaluation index by carbon stable isotope and evaluation on yield of drought resistance, such as specific protein metabolism and QTL of drought-resisting traits. Futhermore, current problems and speculations in wheat drought tolerance were also addressed. As a conclusion, drought resistance would still be a hotspot in agricultural research. However, the focus may vary in different ecological zones. Meanwhile, indexes shown high correlation with yield should primarily be selected for further investigation. Invesgigations on mophorlogical structures and metabolism of root tissue under drought stress needed enhanced more. With the continuous development of molecular biology, research on drought resistance may also need to be conducted through a molecular angel to clarify the causes for physiological and biochemical changes of crops under drought stress. Genetic engineering may additionally need to be eompolyed to recombinate genes related with drought resistance, promoting the initiative and comprehesive cultivatation of superior wheat varieties. |
