| dc.description.abstract | The four cotton genotypes viz., Bio-100 BG II, GCH 3, KDCHH-9810 BG II and HS 6 were evaluated under field conditions to compare their tolarance levels against the sucking insect-pests. The effect of sucking insect-pests on morpho-physiological biochemical constituents viz., the relative water content, specific leaf weight, total chlorophyll content, electrolyte leakage, leaf area, photosynthetic rate, total phenolic content, total soluble sugar, tannin content, total soluble protein, gossypol content, H2O2 content and activity of enzymes- peroxidase and polyphenol oxidase that could explain some of the varietal tolerance levels were tested. Morpho-physiological and biochemical analysis indicated that the highest relative water content, total chlorophyll content, leaf area and photosynthetic rate was observed in Bio 100 BG-II, highest specific leaf weight was observed in GCH-3 and highest electrolyte leakage was observed in HS-6 genotypes. The lowest relative water content, total chlorophyll content, leaf area and photosynthetic rate was observed in HS-6, lowest electrolyte leakage was observed in Bio 100 BG-II and lowest specific leaf weight was observed in KDCHH 9810 BG-II genotypes. The highest total phenolic content, tannin content and POX activity observed in Bio-100 BG II. Gossypol content, total soluble protein and PPO activity were highest in GCH 3. Total soluble sugar and H2O2 content was highest in KDCHH- 9810 BG II. Total phenolic content, gossypol content and tannin content were lowest in HS 6. Total soluble protein and PPO and POX activity were lowest in KDCHH-9810 BG II. Total soluble sugar was lowest in GCH 3. H2O2 content was lowest in Bio-100 BG II. Sucking pest infestation reduced the total soluble sugar and total soluble protein of all genotypes, while other biochemical constituents increased with sucking insect-pests infestation. These results indicated that Bio-100 BG II is highly tolerant as compare to other genotypes. | en_US |
