Formerly trunk rot of apple(Botryosphaeria ribis Gross,et Dugger)was reported onlyoccuring on young trees.Since 1957 it was noted to be one of the serious diseases on matureapple trees in the southern part of Liao-ning province,where the disease developed from themiddle of May to the end of October.There were two peaks of development in a year(i.e.June and August),during which the cankers extended most rapidity.Wounds and lenticelswere found to be the principal entrances of the fungus.The rate of infection reached 62.7%at the points where the bark was injured.Topography was also an influencing factor.Lim-sulfur spray proved to be fairly effective among the nine fungicides tested.Four applica-tions of lime-sulfur in the growing season reduced the trunk rot to less than 50%.Cuttingoff infected tissue or banks was considered as a less effective operation.

根据1960—1961年的研究,苹果干腐病在辽宁省,每年从5月中旬到10月均能发生为害,6月分为发生发展的第一次高峯;8月下旬至9月上旬为第二次高峯。苹果干腐病的发生与气候条件有密切关系。干旱与积水均能诱发病害的发生,而干旱的影响最大。地势与发病亦有影响,低洼地发病较重。树势强弱与本病的发生有密切关系。栽培管理条件好,树势旺壮者,病势一般较轻。喷药保护树干有一定作用,彻底刮治病斑,再涂抹石灰硫磺合剂,效果很好。

在干旱的影响下,较年轻的上端器官,如穗、上茎、旗叶鞘、旗叶能够较久地保持稍好的水分供应,以维持其生理功能。干旱通过水分胁迫的直接影响和促进早衰而减低植物的光合能力,并因同化产物供应不足,使粒重降低导致减产。灌浆前半期经受于旱的处理,因光合产物损失多、减产较多。但在同化产物供应不足的情况下,被利用于充实籽粒的贮存物质的数量则有所增多。中度到近于严重的水分胁迫并不妨碍筛管中物质运输。相反,却因为促进早衰而使叶、茎中所含的氮、磷和糖加速运出。运入每穗籽粒中的氮素和对照近似,磷则明显减少。 讨论了小麦对花后土壤干旱的保护性适应。

This paper chiefly gives account of the fluctuation modes of transpiration intensity, water metabolism rate, water deficiency and foliar water content, etc., for different clones under the influence of low temperature and drought during wintering. The adaptabilities of the clones studied are varied though they have been planted in the northern part of South China for some years. The difference among the fluctuation modes is also suggested.
