Abstract—

In the long-term explosion of mass reproduction of the larch casebearer (Coleophora sibiricella Falkovitsh) in a pure larch stand, the stem phloem responses of larch trees (Larix sibirica Ledeb.) to wounding damage or inoculation of the trunk with the fungal inductor were studied. The mycelium of the ophiostomatoid fungus Ceratocystis laricicola Redfern & Minter and its extractive and the protein fraction obtained from the extractive were used as a fungal inductor. The content of lignin, starch, and condensed tannins (proanthocyanidins) in the phloem was determined at the beginning of the experiment (zero days), and after seven and 14 days. Using ANOVA analysis, it was shown that the response parameters of the phloem did not depend on the kind of the fungal inoculum (P ≥ 0.918), but depended on other factors (P ≤ 0.005), such as damage to the crown by the moth, time from the start of the experiment, and the presence of the inoculum in the wound.

病菌承载者对落叶松的慢性部分脱叶对茎生理参数的影响

摘要—

在纯落叶松林中落叶松arch持者（Coleophora sibiricella Falkovitsh）的大量繁殖的长期爆炸中，落叶松树（larix sibirica Ledeb。）的茎韧皮部对伤口伤害或用真菌诱导剂接种树干的反应是研究。在ophiostomatoid真菌菌丝长喙laricicolaRedfern＆Minter及其提取物和从提取物中获得的蛋白质级分用作真菌诱导剂。在实验开始时（零天）以及在7天和14天后确定韧皮部中木质素，淀粉和缩合单宁（原花色素）的含量。使用ANOVA分析，结果表明，韧皮部的响应参数不依赖于种类的真菌接种物（的P ≥0.918），但取决于其它因素（P ≤0.005），诸如由蛾损坏冠，从实验开始的时间以及伤口中接种物的存在。
