Morphological and Yield Response of Pulses Against Drought Stress: A Review

Abstract

Pulses in Pakistan is used in combination with cereals to balance the diet. Its area and production is decreasing for last many years. In the barren and partly arid regions, water shortage is the major component that restricts yield. Using of drought resistance plant is one of the best ways for good cultivation under drought condition. As the pulses have great nutritional and economical values and drought stress affect their morphological features. The legume yield is mostly cultured in rain fed region of the Punjab where they bear a slighter quantity of water situation resulting in low yield of bean. To overcome these problems it is necessary to get knowledge about the performance of different lines of different pulses crops under water stress conditions. That’s why in this paper the information about the previous literature has been discussed.

Alpha lipoic acid mitigates adverse impacts of drought stress on growth and yield of mungbean: photosynthetic pigments, and antioxidative defense mechanism

“…In plants, photosynthetic pigments such as chlorophylls are indispensable to maintain optimum photosynthetic efficiency by harvesting sunlight ( Tabassum et al, 2016 ). Under water stress conditions, leaf chlorophylls contents disturb seriously but plant species-specific ( Zargar et al, 2017 ; Shin et al, 2021 ) and water stress intensity specific ( Zargar et al, 2017 ; Wang et al, 2016 ; Hussain et al, 2018 ; Tahir et al, 2019 ; Ma et al, 2022 ) as well as in mungbean cultivars ( Uddin, Ullah & Nafees, 2021 ) that corresponds well to present findings. Its results in stomatal closure lead to perturbation in gas exchange attributes associated with reduced leaf area ( Zargar et al, 2017 ; Liang et al, 2020 ).…”

Identification of Sorghum (Sorghum bicolor (L.) Moench) Genotypes with Potential for Hydric and Heat Stress Tolerance in Northeastern Mexico

“…Both plant height and panicle length decrease pre-anthesis under hydric stress mainly as these plant characters define their expression during this phenological stage, which likely induced a decrease in cell turgidity, obstructing water flux from the xylem to adjacent phloem cells, inhibiting their development, and ultimately stopping their growth [67]. Although, in the present study, the magnitude of shortening panicle lengths when hydric stress was applied pre-anthesis was very clear, with a 92% difference (26.7 and 13.9 cm, from Table 4), these results are in agreement with other similar research.…”

Comparative Study of Five Legume Species under Drought Conditions

“…A similar trend for low production of faba bean goes also with chickpea crop (Table 2), however the remaining legume crops (common vetch, lentil and bitter vetch), presented a great production in terms of total yield, grain and hay production except for lentil which revealed high fresh and hay weight allied with the lowest grains (only 5.56 kg/dunum). Nevertheless, lentil is highly subjected to drought that delayed its phenology (Erskine and Saxena, 1993), reduced the root shoot ratio (Dabbagh and Nasab, 2011), affected blossoming and harvesting period (Naroui et al, 2010), reduced branching/sprouting fraction (Tahir et al, 2019) and produced poor seed yields (Shrestha et al, 2005). Based on these finding, we may confidently assume that the yield component variations are genetically controlled rather than environmentally, however some genotypes behaved differently under the tested climatic condition.…”
