The diseased leaf rate and the disease index were related closely to temperature, humidity and illumination etc. The study also showed that the conidium germinating of Pestalotiopsis versicolor started after inoculated for four hours and germinated well at pH5 to pH7. In addition, there was great appetency between the pathogen and the tea trees because the conidia germinated well on tea leaves rather than other habitats obviously.

在茶树叶面上，病原菌分生孢子萌发明显比非叶面条件下好，病原菌菌丝生长较快，说明此病原菌与茶树叶片有高度的亲和力和较强的适应茶树叶面微环境的能力；茶树轮斑病病原菌分生孢子在pH5~7范围内萌发及芽管伸长较好，pH过小或过大均不利于病原菌的分生孢子萌发和菌丝生长。

Experimental results indicated tobacco seedlings became more vigorous while leaves exceeding 5cm were cut by 1/3, showing more obvious overcompensation responses, and these seedlings grew quickly after transplanted, there quality and production value were increased.

试验表明，剪叶时剪去5cm以上叶片的1/3有利烟苗产生超越补偿效应，可明显提高烟苗的成苗素质，促进烟株的早生快发，提高烟叶的烤后产值和质量；剪叶程度增加，明显降低烟苗成苗素质，抑制烟株的生长；不剪叶则导致烟株严重早花。

The length,width,thickness and weight of the current year and more than one-year-old needles of both bi-needle-cluster and tri-needle-cluster of slash pine were measured to expose the differences in terms of leaf shape and specific leaf area,and leaf area index was estimate based on measurement of the plantation in Qianyanzhou Ecological Station.

对湿地松当年生和多年生两针一束、三针一束叶片的长度、宽度、厚度和重量分别进行量测，据此探讨不同类型叶片的叶形和比叶面积差异，并结合样地调查数据对中科院千烟洲试验站湿地松人工林的叶面积指数进行计算。

Leaves apparently alternate, distichous; nanophylls present or absent, opposite to normal leaves; stipules 2; leaf blade 3-veined, one major lateral vein sometimes inserted above the base, or pinnately veined, base asymmetric, margin entire or serrate; cystoliths mostly present, linear or fusiform.

叶表面上互生，2列；微形叶宿存或无，对生于正常的叶；托叶2；叶片3脉，主要的一侧脉高于那些基部，或成羽状脉，基部不对称，边缘全缘或有锯齿；乳状体多数宿存，线或者纺锤形。

Leaves opposite, mostly simple and palmately lobed, sometimes leaves pinnately veined and entire or pinnately (7-)11-21-foliolate, usually estipulate.

叶对生，多数为掌状分裂的单叶，有时全缘的羽状脉单叶，或者羽状复叶具(7-)11-21小叶(金钱枫属Dipteronia)，通常无托叶。

Bioassaying of squash silverleaf assigned the whitefly from Beijing (host: cotton and sweetpotato) and Xinjiang to B biotype. However, populations from Fujian and Guangxi without silverleaf symptom were considered as non-B biotype.

银叶生测实验表明：北京甘薯、棉花和新疆茄子上的烟粉虱为害西葫芦后可引起寄主的银叶，表明属B型烟粉虱；福建甘薯和广西南瓜上的烟粉虱种群在西葫芦上为害不呈银叶属非B型。

Leaves alternate, opposite, or verticillate, base often spurred, margin normally entire 4-8-dentate in Sedum rosthornianum and remotely dentate in S.

轮生的叶互生，对生，或，基部通常距，通常全缘的边缘具牙齿在Sedum rosthornianum 和S。

Leaves opposite or whorled except basal ones alternate; petiole very short or indistinct; leaf blade abaxially glaucous, ovate- or oblong-elliptic, 3.8--6 × 1.4--3.2 cm, glabrous, apex acuminate.

叶对生或轮生的除基部的互生之外；叶柄非常短或不清楚；叶片背面有白霜，卵形或长圆状椭圆形， 3.8-6 * 1.4-3.2 厘米，无毛，先端渐尖。

Leaves simple; stipules subulate; leaf blade ovate-triangular or palmately 3-5-lobed or -parted. Flowers axillary, solitary or fascicled, sometimes grouped into terminal racemes.

单叶 托叶钻形叶片卵状三角形的或掌状的3-5浅裂或深裂花腋生的，单生或簇生，有时组合成顶生的总状花序的。

Compared with progenies of inter-tree-pollinated E.urophyllaagain,progenies of self-pollinated E.urophylla showsignificant inbreeding depression in height,DBH and volume;theyshow no significant inbreeding depression in water content ofgreen wood,basic density and bark thickness;their content of1%NaOH extractives increases significantly,and their maturefiber length decreases significantly.

与尾叶桉株间杂交子代比较，尾叶桉自交子代的树高、胸径和材积具有显著至极显著的近交退化，生材含水率、木材基本密度和树皮厚度无近交退化现象，1％NaOH抽提物含量呈略显著性提高，成熟材纤维长度呈显著性减短；尾叶桉自由授粉子代的近交退化规律大致与自交子代相同，但其退化程度远不及自交子代。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
