“…Sugarcane is a commercial crop majorly for production of sugar and ethanol in the world. Although sugarcane has been blessed with certain natural abilities to tolerate such water deficit conditions yet sugarcane growth and development has been effected by drought condition (Shrivastava et al, 2017, Shrivastava et al, 2015). Studies had illustrated that stomatal closure, stalk inhibition, leaf senescence, leaf area reduction and leaf growth inhibition are few physiological responses which are widespread seen in water stress condition in sugarcane (Inman-Bamber and Smith, 2005, Inman-Bamber et al, 2012).…”

Sugarcane is a significant crop for production of sugar and ethanol in the world. In present perspective, drought is one of the frequently occurring abiotic stresses hampering the productivity of sugarcane causing heavy losses in sugar recovery. Post-harvest sugarcane deterioration attains more importance. Measures have been recommended in harvested canes to prevent these losses in general and under drought conditions but application of chemical formulation has not yet been tested over drought effected ones. Thus, we tried to investigate the efficacy of chemical formulation [Benzalkonium chloride (BKC) + Sodium metasilicate (SMS)] on sucrose losses occurring in harvested canes grown under drought and normal conditions. Results showed that application of chemical formulation had higher effect on drought canes in comparison to normal grown canes. Loss in cane weight was reduced to 8.25% and 11% in drought treated and normal treated grown canes, respectively, after 240 h of harvest in comparison to their respective control. In sucrose content and Commercial cane sugars %, drought treated canes showed an effect of BKC + SMS by reducing the losses to 1.26 units and 1.42 units, respectively, whereas in normal ones, reduction was of 0.38 units and 0.10 units, respectively. Biochemical analysis revealed that in reducing sugars, reduction in increase were of 44.51% and 25.50% in drought and normal grown canes, respectively, after 240 h of harvest. Dextran and soluble acid invertase estimations revealed that after application of BKC + SMS, reduction of dextran and invertase activity were of 49.74%, 66.84%, respectively, and 33.92%, 42.75%, respectively, in drought and normal grown canes, respectively. Total microbial load, showed effectiveness of 25.01% in drought grown canes while 14.41% in normal grown ones after 240 h of harvest. Our study was planned to use the anti-bacterial efficiency of both the chemicals over harvested canes so that the major sucrose losses occurring due to microbial deterioration could be inhibited. The use of this chemical formulation proves to be an effective one over post-harvest sucrose losses, particularly in drought grown canes.

“…These stressors directly or indirectly impact sugarcane by altering its growth, metabolism, and development. Moreover, they can affect soil health, crop chemistry, sugar accumulation, and seed cane availability, exacerbating the effects of other abiotic or biotic stresses and resulting in increased losses . Among the abiotic stressors, water stress holds the utmost significance in affecting sugarcane production.…”

As highlighted by Zingaraetti et al, 5 water stress occurs when plants receive inadequate water or experience an increase in transpiration rates.…”

Exogenous hormones play a crucial role in regulating plant growth, development, and stress tolerance. However, the effects of exogenous abscisic acid (ABA) on sugarcane seedlings under water stress remain poorly understood. Here, in this study, a pot experiment was conducted on sugarcane seedlings 4 weeks after transplanting, employing three treatments: control (normal growth), drought (water stress), and drought + ABA (foliar application of 100 μM ABA before water stress). The main objectives of this research are to understand the effects of exogenous ABA on sugarcane seedlings under water stress conditions and to assess the changes in antioxidant enzyme activity and phytohormone levels in response to exogenous ABA. Water stress was induced in the solution culture by adding 25% (w/v) polyethylene glycol (PEG) 6000 to the Hoagland solution. Leaf samples were collected at 3, 6, and 9 days after treatment, and the photosynthetic and biochemical responses of ABAtreated plants to drought stress were investigated. The indole acetic acid (IAA) activity of the ABA-treated drought plants is compared to that of drought plants. Moreover, the endogenous ABA levels of the ABAtreated drought plants were significantly enhanced by 42.2, 39.9, and 42.3% at 3, 6, and 9 days, respectively, compared to those of drought plants. Additionally, the proline content of the ABA-treated drought plants significantly increased by 45 and 80% at 6 and 9 days, respectively, compared to that of drought plants. The expression of the catalase 1 (CAT1) gene was increased in the ABAtreated drought plants by 2.1-fold, 0.7-fold, and 1.37-fold at 3, 6, and 9 days, respectively, compared to that in drought plants. Similarly, the expression of superoxide dismutase, peroxidase, and ascorbate peroxidase genes of the ABA-treated drought plants also increased compared to those of the drought plants. In conclusion, foliar application of ABA mitigated the negative effects of water shortage of sugarcane plants under water stress. Applying ABA improved the antioxidant defense system of sugarcane plants under drought stress, thereby enhancing their photosynthetic activities and productivity.
