项目摘要
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.
以拟南芥为材料,研究了成熟叶片对叶片发育的影响。部分遮光试验表明,成熟叶片的光合作用和/或光环境的强烈影响。用赤霉素(GA_3)、苄基腺嘌呤(BA)、烯效唑(GA_3合成抑制剂)或它们的混合物溶液喷施植株地上部。喷施后植株形态发生明显变化。GA 3和BA提高了生物量在叶片中的分配,而烯效唑降低了生物量在叶片中的分配。GA 3降低了单位面积叶重,烯效唑提高了单位面积叶重,这些植物激素与叶片的形态、光合速率、净同化速率等生理指标以及相对生长速率之间存在密切的关系,可能参与了不同光氮条件下生物量分配的调节。
