Drought-induced Changes in Chlorophyll Stability Index, Relative Water Content and Yield of Cotton Genotypes

Effect of Biochar, Mulch and Ppfm Spray on Leaf Relative Water Content, Leaf Proline, Chlorophyll Stability Index and Yield of Cotton under Moisture Stress Condition

“…The observed significant decrease in RLWC under moisture stressed condition was due to reduced absorption of water from the soil and inability to control water loss through the stomata. Our results are in assenting with the findings of Kumar et al, (2012) and Ananthi et al, (2013).…”

“…Leaf relative water content (RWC) is an important indicator of water status in plants; it reflects the balance between water supply to the leaf tissue and transpiration rate (Lugojan and Ciulca, 2011). The chlorophyll stability index is an indicative of the maintenance of photosynthetic pigments under moisture stress condition (Ananthi et al, 2013). The results with respect to RLWC and CSI differed significantly with differing moisture regimes and moisture management with biochar application regimes to conserve moisture at different stages of crop growth.…”

Physiological and Biochemical Evaluations for Identification of Drought Tolerance Potential in Doum Palms (Hyphaene Compressa) under Water Deficit Treatment

“…Due to decreased soil water absorption and the inability to manage water loss under water deficit conditions, RLWC decreased significantly. Our findings align with those of other researchers who have used chickpeas and cotton in their studies [25], [26].…”

Influence of Biochar, Mulch and PPFM on Stress Physiological Parameters of Cotton under Moisture Stressed Condition

“…The observed significant decrease in RLWC under moisture stressed condition (12 and 10% decrease at 105 DAS during summer and winter) was due to reduced absorption of water from the soil and inability to control water loss through the stomata. Similar results were reported by Kumar et al (2012); Ananthi et al (2013). Among the moisture stress management practices, application of Prosopis biochar+crop residue mulch at 5 t ha -1 +foliar application of PPFM at 500 ml ha -1 at 75 and 90 DAS (B 6 ) recorded higher RLWC (74.7 and 77.3% at 105 DAS) during summer and winter seasons.…”

“…The chlorophyll stability index is an indicative of the maintenance of photosynthetic pigments under moisture stress condition (Ananthi et al, 2013). The higher CSI indicates the moisture availability in leaves and it leads to increase in photosynthetic rate, dry matter production and high productivity.…”
