Grain Sorghum Caryopsis Development: II. Changes in Chemical Composition¹

Abstract

Synopsis Changes in amounts of nitrogen, total sugars, starch, and acid hydrolyzable carbohydrates followed closely changes in dry weight of Combine Kafir‐60 sorghum caryopses harvested at 3‐day intervals after pollination. Diastatic activity was closely associated with percentage germination.

Leaf Removal in Grain Sorghum. II. Trends in Dry Matter, Carbohydrates, and Nitrogen Following Defoliation1

“…Percentages of nitrogen, total sugars, and acid hydrolyzable carbohydrates were determined as outlined by Kersting et al ( 2). Dry matter-Increases in dry matter were obtained in all treatments following defoliation, except complete defoliation during anthesis.…”
