Research Abstract

Effects of the mature leaves on leaf development were studied with Arabidopsis. Partial shading experiments revealed the strong influence of mature leaf photosynthesis and/or light environment.
Seedlings of Polygonum cuspidatum were grown under various light and nitrogen availabilities. We exogenously sprayed solutions of gibberellin (GA3), benzyl adenine (BA), uniconazole (an inhibitor of GAs synthesis) or their mixtures on the aboveground parts. The morphological traits were markedly changed by the spraying. Biomass allocation to leaves was increased by GA3 and BA, whereas it decreased by uniconazole. GA3 decreased the leaf mass per area, while uniconazole increased it. We found close relationships among the morphological traits, physiological traits such as photosynthetic rate and net assimilation rate, and relative growth rate under all the growth conditions.These phytohormones may be involved in regulation of biomass allocation in various light and/or nitrogen availabilities.
