从越冬芽发育而来的第一轮新梢上茶饼病的发生部位与其它季节新梢茶饼病的发生部位是显著不同的。第一轮新梢上47.5%的茶饼病发生在最先发育的叶面上,第二片叶上88.5%的茶饼病在中脉上发生。而秋季第二轮新梢上第一片叶和第二片叶发生茶饼病的仅为18.5%和26.6%。秋梢茶饼病发生在中脉上的,第一片叶占16.2%,第二片叶的占5.2%。对越冬芽进行形态学观察,发现由芽发育而来的第一片叶和第二片叶中脉部位是真菌感染的唯一部位。
From the wintering buds developed the first round of shoots on the first part of the occurrence of cakes disease and other seasonal new cakes disease occurs significantly different parts. In the first round of shoots, 47.5% of the cakes occurred on the first developing foliage, and 88.5% of the cakes on the second leaf occurred on the midrib. In the second round of autumn shoots, only 18.5% and 26.6% of the cakes occurred on the first leaf and the second leaf. Autumn tip tea cake disease occurred in the midrib, the first leaf accounted for 16.2%, the second leaf accounted for 5.2%. Morphological observation of the overwintering buds revealed that the first leaf and the second leaf midrib that developed from the bud were the only sites of fungal infection.
