Papaya leaf curl samples collected from Guangxi province and 1 from Guangdong province, and 5 ageratum yellow vein samples from Guangxi province were tested with triple antibody sandwich ELISA and PCR, Results showed all the virus samples were infected by whitefly-transmitted geminiviruses.

利用三抗体夹心ELISA及PCR检测的方法对采自广西的7个番木瓜曲叶病样品和广东1个番木瓜曲叶病样品，及采自广西胜红蓟的5个黄脉样品进行了检测，表明均为粉虱传双生病毒。

"Bloodroot:a perennial wildflower, native to forests in eastern North america and having a fleshy rootstock exuding a poisonous red sap, a single lobed leaf, and a solitary white flower in early spring."

血根草：一种多年生的野生植物，原产于北美洲东部的森林，根茎鲜艳，叶汁红色且有毒，叶单生，早春开白色单花。

The results showed that the overexpression of CBF1 could obviously improve cold tolerance of plant.Compared with non-transformed control plants,the transformed plants had a shorter and stronger stem,more leaves that were bottle-green and thicker,and a longer growth period.

结果表明：CBF1的组成型表达增强了冷敏感植物的抗寒性；在表型上使植株矮壮，叶片着生密集，叶色深绿，叶厚度增加；促进侧枝生长，延长营养生长期，推迟花期；对植株的结实性无明显影响。

There are differences between sexes and among different ages in the caudate lobe of liver in normal adults.

结论成年人肝尾状叶在不同性别、不同年龄段之间存在差异，肝尾状叶超声测量及诊断时应注意到这种生理性差异。

Flowers solitary or arranged in small cymes or fascicles, axillary, opposite to leaves, bisexual; peduncle very short.

Leaves opposite or alternate, rarely whorled, simple, 3-foliolate, or odd-pinnate; petiole usually articulated.

叶对生或互生，很少轮生，单，具3小叶，或奇数羽状复叶；通常的叶柄有节。

Leaves mostly odd-pinnate; inflorescences terminal or terminal and axillary; plants dioecious

叶多数奇数羽状复叶；花序顶生或顶生和腋生；植株雌雄异株 3

Biological characteristics of the pathogen and the resistance of 13 cultivars of tea plant to tea brown blight were studied by means of natural infection in the field and artificial inoculation in vitro. Resistant cultivars and susceptible cultivars of tea plant were divided. And the resistance mechanism was researched tentatively. The findings are as follows: 1 Some biological characteristics of the pathogenic fungus The experiment result showed: the optimum temperature for the growth of fungus mycelium was from 24 to 27℃, the optimum temperature for sporulation ranged 22 to 30℃. Treated at 54℃ in 10 minutes, the spores didn't germinate. The optimum pH for the growth of the mycelium was 5.1～5.9, the optimum pH for sporulation ranged 5.0～6.0. Light had no much effect on the growth of fungus mycelium, but had much effect on the reproduction of the spore.

首先，研究了茶云纹叶枯病病菌的生物学特性；其次，通过田间抗性调查和室内人工接种鉴定，对 13 个茶树品种进行了抗病性鉴定；第三，在前人研究的基础上，对茶树抗病机理作了更深入的研究，结果发现： 1 病原菌的生物学特性病原菌的分生孢子萌发的最适温度范围为 24～27℃，菌丝生长的最适温度范围为 22～30℃；致死温度为 55℃；菌丝生长的最适 pH 范围为 5.1～5.9，孢子萌发的最适 pH 范围是 5.0～6.0；光照对病菌生长速度及分生孢子萌发影响不大，但对其产孢的影响很大，特别是有光照与无光照处理之间差异显著，光照有利于分生孢子的形成。

Leaves grow in clusters; stipe chestnut brown, shiny ; blade pentagonal, Zhang Kuange about 5-7 cm, there are three separate base, or connected to cleft pinna feather, apical pinna nearly diamond-shaped, triangular lateral pinna, feather shaft under the lateral side of the sliver compared with the previous long, the base of one the longest; vein plume bifurcation; leaves dark green above, here are milky white or milk yellow powder.

叶簇生；叶柄栗棕色，有光泽；叶片五角形，长宽各约5—7厘米，有3片基部相连的或分离的羽裂的羽片，顶生羽片近菱形，侧生羽片三角形，羽轴下侧的裂片较上侧的长，基部1片最长；叶脉羽状分叉；叶片上面暗绿色，下面有乳白色或乳黄色粉末。

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。
