Item Alterations in the leaf protein content of coconut affected by root (wilt) disease(2007-02-08) Padmaja, G.; Sumathy Kutty Amma, B.; Chacko Mathew; Nambiar, P.T.N.; Snehi Dwivedi, R.Changes in the protein content of leaves from healthy and root wilt affected coconut palms have been studied. Alkali—extractable, water—extractable and ethanol—extractable protein fractions were found to be higher in the healthy palms when compared to the diseased palms. A preferential extraction of proteins at low pH values could be obtained in the middle and outer leaves from apparently healthy and diseased palms. An increase of 53.7% and 24.9% over the protein values in the healthy palms was noticed in the middle and outer leaves respectively of the apparently healthy palms while the increase was 42.8% and 14% in the respective leaves of diseased palms. The implications of the protein changes in root (wilt) disease have been discussed.Item Alterations in the leaf protein content of coconut affected by root (wilt) disease(1980-02) Padmaja, G.; Sumathy Kutty Amma, B.; Chacko Mathew; Nambiar, P.T.N.; Snehi Dwivedi, R.Changes in the protein content of leaves from healthy and root wilt affected coconut palms have been studied.

Higher activity was obtained in the diseased palms when compared to the healthy ones. The results of the study indicate that cellulase might be one of the factors responsible for the vast decay of roots observed in the diseased palms.Item Cellulase activity in the roots of coconut palms affected by root (wilt) disease(1979-12) Padmaja, G.; Sumathy Kutty Amma, B.Cellulase activity was determined in the roots of healthy and root (wilt) diseased coconut palms. Higher activity was obtained in the diseased palms when compared to the healthy ones. The results of the study indicate that cellulase might be one of the factors responsible for the vast decay of roots observed in the diseased palms.
