Carbohydrate Distribution as Affected by Calcium Deficiency in Cotton.

Abstract

In cotton an inverse relation was found to exist between leaf carbohydrates (sucrose, reducing sugars and starch) and substrate Ca, while carbohydrates of the stems and roots tended to be directly dependent on substrate Ca. A comparison was made between Ca and N deficiency and it was noted that Ca deficiency limited carbohydrate translocation. Both Ca and B deficiencies were noted to exert similar influences on the distribution of carbohydrates. Growth and fruiting of cotton were found to be directly related to substrate Ca.
