    Abstract: Plants continuously struggle for survival under various environmental abiotic stress conditions, specifically high temperature. Fourteen-day-old seedlings of Cassia tora and Cassia auriculata were subjected to differential temperature stress treatments at 30ºC, 37ºC, 42°C and 44°C for 16 h each. Various biochemical parameters viz reducing sugars, t... Show More

    Abstract: Plants, in contrast with vertebrates, have no immune system. So they are affected by pathogens easily leading to remarkable yield loss altogether. Fungal phytopathogens pose serious problems worldwide in the agriculture sector, and harmful and costly chemical fungicides are nowhere a match to them. A detailed study was performed to screen the coop... Show More
