Abstract

Comparing with spectral signature and preexisting indices, maximum R values was observed in RWC and pigment analysis than other biochemical parameters. According to the spectral signature, the Sugarcane variety MS-10001 showed maximum drought stress tolerance compared to Co-86032. In citrus plants, fully irrigated treatments clearly differentiated with deficit water treatments. • Haematoxylin-eosin staining of white muscle morphology exhibited hypertrophic growth at higher diurnal temperature. Enhanced thermal tolerance was observed at higher diurnal temperature regime, CTMax of 43.26°C and CTMin of 11.3°C in comparison to lower diurnal temperature regime, CTMax of 42.62°C and CTMin of 10.2°C. • It was observed that fish Oreochromis mossambicus exposed to higher diurnal temperatures grew 11.2% more than fish exposed to lower diurnal temperatures. Increase in metabolic rates with increase in diurnal fluctuating temperatures is also observed. This study suggests that the diurnal fluctuating temperatures increase the ability of O. mossambicus to adapt to increasing temperature regime.
