Physiol. & Biochem., 16(1) : 52-56, 1989.—The rate of How of phloem sup from the inflorescences of coconut depends on the nature of the palms. While healthy palms yielded sap for longer duration in large quantities, root (wilt) diseased palms had less sap flow for restricted period. There were differences between healthy and diseased palms in the day and night collection of sap and its chemical composition. Sap flow varied between successive inflorescences of the same palm.enCocos nucifera LInflorescencePholem sapRoot (wilt) diseaseArticle
