Studies on the Influence of Fruit Development on Seasonal Elemental Ooncentrations and Distributrion in Fruit and Leaves of Pecan and the Influence of Foliar K Applications on Pecan Seedlings

Abstract

This study was conducted to determine the seasonal influence of fruiting on elemental concentrations in pecan leaves, major periods of mineral movement into the fruit, and distribution of elemtents within the maturing fruit. Particular reference was made to theK nutrition of pecan and and alternative method of supplying K by way of foliar applications. Chapter II, The Influence of Fruit devleopnent on Seasonal Elemental Concentrations and Distribution in Fruit and Leaves of Pecan, was submitted for publication in Ccmnunications in Soil Science and Plant Analysis. Chapter III, Influence of Foliar Applications of K2 so 4 and. KN0 3 , plus Urea and NH 4No 3 Spray Adjuvants, and Surfactants on K Concentration of Pecan Seedlings, was revised and submitted for publication in HortScience.
