effect of high temperature stress on plant pigment depended on type of genotype. however high temperature stress decrease amount of plant pigment due to its destructive.
the chlorophyll a, b content decreased under high temperature stress due to competition in increasing in active of enzyme of proline catalysis and limitation in activity of enzyme of chlorophyll biosynthesis.
