寄生植物

Mainly belonged to Loranthaceae. Plants of Phacellaria Benth. and their hosts were mainly distributed in tropical and subtropical area. Plants of Phacellaria Benth. maybe originated in tropical area in the south of China before Tertiary. Their ancestors were parasitic on ancestors of some plants of Loranthaceae by chance during Tertiary. It took them millions of years to form a sturdy relationship between parasites and hosts. Ph. rigidula was a hemi-parasitic subshrub. In area observed, its host was mainly Taxillus caloreas var. fargesii.

的硬序重寄生(Ph.rigidula)及其寄主植物做为研究植物与植物间协同进化的材料，对重寄生属植物的起源、与其寄主的分布、硬序重寄生的形态学特性、解剖学以及化学成分进行了研究，结果表明：重寄生属植物主要寄生在桑寄生科植物上，分布区与其寄主的基本一致，均主要分布在东南亚和中国南部的热带与亚热带地区；重寄生属植物可能起源于第三纪之前某一时期的华南热带地区，随后向周边地区扩散。

Domestic and foreign has conducted extensive research to the phytoparisite process, quininones, the hydroxyl acids and flavonoids are identified as haustorial inducing factors in the perception of the host plants.

国内外对植物寄生过程进行了广泛的研究，普遍认为醌类、类黄酮类、酚类3大类化学物质为植物寄生过程中的化学信号物质。

The species belonging to this genus are obligate holoparasites on the plants of Loranthaceae and Dendrotrophe.

重寄生属植物的寄主仅局限于桑寄生科和檀香科寄生藤属的植物。

The species belonging to this genus are obligate holoparasites on the plants of Loranthaceae and Dendrotrophe.

重寄生属植物的寄主仅局限於桑寄生科和檀香科寄生藤属的植物。

The feature adaptation of P.rigidula and the evolution of the parasitic shrubs had been discussed. Some of the characteristics based on the superparasitic chains elucidate the evolutionary processi...

讨论认为，重寄生链上的一些渐变特征展现林木上寄生灌木具有 2个演化阶段，即以自养树木为寄主的半寄生灌木演化阶段，和以树木上半寄生灌木为直接寄主的重寄生灌木演化阶段；重寄生属植物特殊的生活习性和形态结构特征，是与其在寄主桑寄生科半寄生灌木上生活的特殊环境相适应的，是与其寄主、传播花粉蚂蚁类昆虫和传播种子鸟类协同演化的结果。

Due to plant-parasitic nematodes parasitizing on plant tissues,uptaking nourishment from host cell through stylet,the crystal protein is difficult to enter into nematode through stylet.

由于植物寄生线虫大多专性寄生，主要依靠其刺吸式口器—口针从植物细胞内吸取细胞内含物的方式来取食，晶体蛋白很难通过其口针直接进入体内。

In Hubei. After screening, two strains of fungal parasites were gottenwhich had stronger. ability to parasite Meloidogyne eggs. Their parasitic ratio tothe root knot eggs was 78.04% and 70.02% in concave slides and water agar plates,72.37% and 65.65% in pots. The effective hatchings in experimental containers wereonly 5.02% and 8.32%, and there were 100% in controls.

危害的根和根围土壤64份样品，采用3种方法分离，经过筛选测定，获寄生能力较强的真菌2株，室内凹玻片和琼脂平板法测定结果表明，对卵的校正寄生率分别为78.04%和70.02%；室外盆栽测定的寄生率分别为72.37%和65.65%，供试卵有效孵化率为5.02%和8.32%，对照卵为100%。4%土重的棉籽壳真菌制剂能有效控制根结线虫第一代卵量，有效用量的10倍菌剂盆栽测定对植物均没有不良影响。

The grapevines are parasitic yet high-aspiring.

葡萄藤虽是寄生植物却心存高远，力争上游俯视整个尘世。

Plant parasitic nematodes were one of important pathogens. They were dangerous to crops in all over the world.

植物寄生线虫是植物病害的重要病原物之一，其寄生范围广，对全世界农作物生产构成了严重威胁。

It lives only on hemi-parasitic plants. Its main host is Taxillus caloreas var.

该种植物专营重寄生生活，主要寄生在桑寄生科的显脉松寄生上。

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。
