影响插穗生根的主要小气候因子是:湿度、空气和基质的温度、光照度、基质的通气性、空气和土壤的气体组成、基质的物理和化学组成,以及水的化学组成等。小气候条件对绿枝插穗生根的作用,首先是它决定插穗基部分生组织形成中生理过程的活性、同化作用的强度,以及叶子中激素的生产率,而这种激素直接与生根过程有关。湿度:生根环境中基质和空气的湿度影响插穗在生根时的水分状况。绿枝扦插的研究者指出,维持插穗的膨压,保持其高的起始水分贮量,对生根起着重要作用。插穗和叶子组织中的充足的水分含量,对分生组织的活性,特别对于形成层的活性是必须的条件。截取插穗后立即扦插,由于插穗保持有大量的水分,生根率达100%,经过一昼夜仅为18%,经过两
The main microclimate factors affecting rooting are: humidity, temperature of air and matrix, illumination, aeration of matrix, gas composition of air and soil, physical and chemical composition of matrix, and chemical composition of water. The effect of microclimate on the rooting of green shoots is firstly that it determines the activity of physiological processes, the intensity of assimilation and the productivity of the leaves in the root part of the cuttings, which is directly related to the rooting process. Humidity: The moisture content of the substrate and air in the rooting environment affects the water status of the cuttings at rooting. Researchers of green shoot cutting pointed out that maintaining turgor cuttage and maintaining its high initial water storage capacity play an important role in rooting. Adequate moisture content in cuttings and leaf tissue is essential for meristem activity, especially for cambial-forming activity. Cuttings cut immediately after cuttings, cuttings to maintain a lot of water, rooting rate of 100%, after only a day and night only 18%, after two
