Table 4. Morphological and physiological adaptations to stress in millets.

Crop	Morpho-physiological parameters	Effect on plants	References
Little millet	Root length and shoot length	Root length increased gradually in all drought condition while shoot length decreased	[28]
Foxtail	Root hair density and length	Results showed that under water stressed condition root hair density and length increased.	[29]
Foxtail	Root length and shoot length	A significant reduction in shoot length while root length increased	[30]
Finger millet	Plant height, leaf area total dry matter (TDM), root/shoot ratio by weight and length, grain yield and harvest index	Plant height, leaf area, total dry matter,root/shoot ratio by weigh, grain yield and harvest index decreased while root/shoot ratio by length increased	[18]
Finger millet and barnyard millet	Relative water content and chlorophyll content	Moderate rate of decline of RWC and chlorophyll	[24, 25]
Proso millet, Foxtail millet and Pearl millet	Seed number per ear and ear number per plant number of tiller, harvest index ear, peduncle and ear length and plant height	Water stress caused reduction in the number of tiller and ear, peduncle and ear length, seed no., harvest index and plant height.Their results showed that foxtail millet showed the greatest yield in both stress and non-stress conditions among other crops.	[31]
Finger millet	Leaf area, dry matter, seed weight and yield	Significant reduction in leaf area, dry matter accumulation, seed weight, radiation use efficiency and yield	[21]
Pearl millet	Plant height, biomass, panicle, stalk length, no. of leaves, total grain no. and weight	They observed a significant redcution in plant height, biomass, panicle, stalk length, no. of leaves, total grain number and weight	[23]
