Evaluation of the most adequate organ of reference for sap analysis in the tomato plant

Abstract

The most adequate organ of reference for sap analysis is studied during the phenological stage corresponding to the fructification of the second flower bud in the tomato plant grown in hydroponic culture with normal nutrient solution. Thus, the composition of the sap extracted from petioles of leaves in different stages of growth is studied. The results obtained indicate that the sap extracted from the petioles of fully grown young leaves is the best for achieving a nutritional study of the tomato plant. © 1991 Academia.
