TLDR
The results proved that Chlorophyll content, MSI, RWC and Fv/Fm are good physiological indices of drought tolerance and can be used for improvement drought tolerance in wheat.Abstract:
Tolerant and susceptible durum wheat varieties were grown in the 1 st and 2 nd settlement zone under rainfed conditions inDaraa province-Syria, In order to expose plants to different level of water regime, since the two zones differ in total amount of rainfall during the growing season. Plants were suffered from terminal drought stress in both zones, however, the drought was more sever in the 2 nd settlement zone. All measured parameters: chlorophyll content, MSI, RWC, Fv/Fm decreased significantly in the 2 nd compared to the 1 st zone at all growth stages, however more reduction was recorded in drought susceptible varieties. Yield all yield components also affected negatively and drought tolerant varieties have maintained good performance in the 2 nd zone. Our results proved that Chlorophyll content, MSI, RWC and Fv/Fm are good physiological indices of drought tolerance and can be used for improvement drought tolerance in wheat.read more

TL;DR: Drought stress had a greater effect than heat stress on yield and the biochemical seed-filling mechanisms, and drought- and heat-tolerant genotypes showed partial cross-tolerance.

TL;DR: Drought stress inhibited the biochemical processes of seed filling more than heat stress, and the combined stress had a highly detrimental effect; a partial cross tolerance was noticed in drought and heat-tolerant lentil genotypes against the two stresses.

TL;DR: Physiological trait-based breeding, molecular breeding, marker-assisted backcrossing, aerial phenotyping, water budgeting, and resource allocation are modern approaches used to develop drought tolerant wheat cultivars and Wheat genotypes produced as a result of a combination of all these methodologies will increase food security regarding the currently changing climate.
