摘要
采用种皮透水性测定、种胚和种皮提取液生物测定、层积处理和赤霉素溶液浸种等方法,研究三角槭种子的休眠和萌发特性,结果表明:引起种子休眠的主要原因是三角槭种子本身含有发芽抑制性物质,赤霉素浸种处理有助于缩短低温层积的时间而使种子发芽时间提前,低温层积42 d后可逐步解除其休眠.
The seed dormancy and germination properties of Acer buergerianum were studied by means of applying determination of water permeability of pericarp, the bioassays of embryo and periearp extracts, the stratification treatment and soaking with GA solution. It was showed by the results that the germination inhibitor within the seed was the main eause for seed dormancy, soaking with GA solution could reduce the duration of low temperature stratification and promote the seed germination. It was showed that the seed dormaney could be gradually overcome by low temperature stratification after six weeks.
