Total soluble sugars and starch in curly Mitchell grass (Astrebla lappacea) as related to vegetative growth stage

Abstract

Growth of A. lappacea from seed, as shown by starch and soluble-sugar contents of the above-ground parts, was studied in pots for 100 days under non-limiting conditions of moisture, radiation and nutrient supply. Plants established a reserve of starch and sugars particularly between 50 and 80 days. Regrowth was poor when plants were defoliated before this storage period.-F.A.S.
