Tree strategies of sprouting new shoots : why do trees have different ability of sprouting?

树木发芽的策略:为什么树木的发芽能力不同?

基本信息

项目摘要

To examine the site and age dependency in the ability of sprouting new shoots for tee seedlings, naturally growing Quercus crispula seedlings were experimentally cut and monitored. Total non-structural carbohydrates(INC), as the resource for sprouting, were also measured. Although this species can establish considerably under wide range of light condition, sprouting ability differed among microhabitats : Q.crispula easily sprouted at open sites, coinciding with large amount of TNC in its root.To investigate seasonal dynamics after a disturbance was investigated for Quercus serrata, the most common oak tree in temperate regions, Japan, that has high sprouting ability. Cutting experiments were carried out in May, June, Jury and August for three-year old Q.serrata seedlings and shoot recovery process was investigated with dynamics of TNC in roots. For intact seedlings, above ground biomass strongly correlated with structural part of roots rather than whole root biomass, suggesting TNC had a function that was not directly related to the ordinal growth. After the cutting, almost seedlings sprouted new shoots during the first month, and its dry mass could be explained with the root TNC at the time of cutting, indicating the high content of TNC is for shoot recovery after disturbance. Although recovery rate in biomass depended on the cutting time and light condition, all seedlings tended to complete recovering root shoot ratio to the intact level at the end of the season, and TNC restoration was also finished for the seedlings cut in May or June.
为了研究自然生长的栎苗新芽萌发能力的位置依赖性和年龄依赖性,对自然生长的栎苗进行了扦插和监测。总非结构性碳水化合物(INC)作为发芽的资源,也被测量。虽然该物种可以在较宽的光照条件下生根,但其发芽能力在不同的微生境中存在差异:在开阔的地点容易发芽,其根部含有大量的TNC。摘要以日本温带地区最常见、发芽能力强的栎为研究对象,对干扰后的季节动态进行了研究。在5月、6月、7月和8月分别对3年生塞拉塔幼苗进行了扦插试验,利用根系TNC的动态变化研究了幼苗的恢复过程。对于完整幼苗,地上部生物量与根系结构部分而非全根生物量密切相关,表明TNC具有与有序生长不直接相关的功能。扦插后的第一个月,几乎幼苗都长出了新芽,其干质量可以用扦插时根系的TNC来解释,说明TNC含量高是为了干扰后的新梢恢复。虽然生物量的恢复速率与刈割时间和光照条件有关,但所有幼苗在刈割季节结束时都倾向于完成根冠比恢复到原状水平,5月或6月刈割的幼苗也完成TNC恢复。
