Abstract
The patterns of allocation of structural and nonstructural carbon were followed in the co-occurring desert ephemerals Plantago insularis and Camissonia boothii. Patterns of biomass distribution were determined from material harvested at biweekly intervals as were levels of nonstructural sugar and starch. Seasonal patterns of growth and reproduction differed markedly with Plantago allocating significantly more structural and nonstructural carbon to reproduction early in the season. Plantago completed its life cycle in less than 60 days but Camissonia continued both vegetative and reproductive growth to over 100 days. The longer growing season of Camissonia was possible because more energy was allocated to vegetative tissues and storage presumably as investment toward longer life and higher levels of reproduction.This publication has 25 references indexed in Scilit:
