Abstract :

 The feeding of the silkworms on the leaves of mulberry is one of the significant components of sericulture. Thus, the leaf quality has an obvious impact on the performance of silkworms. Leaf senescence marks one of the critical phase in the life of leaves which is a genetically programmed and environmentally modulated event. Hence an attempt has been made to study the changes in levels of enzyme dehydrogenase in young, mature and senescent leaves of all the three mulberry cultivars Viz. M5 (K2), V1 and S36. It is evident from the figure, that the young leaves of three cultivars have the highest dehydrogenase activity as compared to mature and senescent leaves. The young leaves of cultivar V1 have shows the highest enzyme activity followed by significant decrease in the enzyme activity in mature and senescent leaves as compared to cultivars S36 and M5 (K2).
