The results showed S curve for effects of NaCl stress on germination of watermelon seed, the middle point between two inflexions of the curve was at 120mmol/L and could be used as referenced screening concentration to study 'ZQK0395' salt tolerance genetics, the second curve inflexion was at 180mmol/L and could be used as referenced concentration for 'ZQK0395' salt-tolerant germplasm selection.

结果表明，NaCl胁迫对种子发芽的影响呈S型变化曲线，120mmol/L为S型曲线两个拐点中间值，可作为该种质资源耐盐性遗传研究的参考鉴定浓度，180mmol/L为S型曲线的第二个拐点，可作为该种质资源耐盐性参考筛选浓度。

In addition, Ca〓 ionophore A〓 impeded pollen germination and tube growth.

此外，Ca〓载离子体A〓亦抑制花粉萌发和花粉管生长，但与Verapamil和Co〓的效应不同，花粉管生长过程对A〓比花粉萌发敏感得多，表明花粉管中Ca〓极性分布对花粉管生长的重要性。

By studying preliminarily the biological characteristics of Neovossia horrida,screening experiment of controlling fungicides on rice kernel smut and surfactant, theresults are as fallows. 1. Studies on biological characteristics of Neovossia horrida indicate that thegermination of the chlamydospores is not at the same pace, the germination of thechlamydospores lasts more than 60 days, and some chlamydospores can germinatewithout dormancy.

本文通过对稻粒黑粉病病原生物学特性、防治药剂筛选和水面扩散剂的初步研究，得出如下结论： 1、病原生物学特性研究表明：病菌冬孢子的萌发相当不整齐，持续期长达60d以上；并发现极少数孢子不需要休眠即可萌发。

The green, filamentous growth that arises from spore germination in liverworts and mosses and eventually gives rise to a mature gametophyte.

原丝体由叶苔或苔藓的孢子萌芽发展而成的绿色丝状生长物，最终发展成配子体

The green,filamentous growth that arises from spore germination in liverworts and moss es and eventually gives rise to a mature gametophyte.

原丝体由叶苔或苔藓的孢子萌芽发展而成的绿色丝状生长物，最终发展成配子体

The purpose of this study was to determine the relationship between abscisic acid and the development and germination of the seed of Pachira macrocarpa.

结果表明：马拉巴栗种子发育过程中，种皮、子叶和胚轴的ABA含量先升高，后下降，最高值出现在花后50 d，最高值分别为791.45、352.68和567.85 ng/g，种皮中ABA具有向内扩散的趋势，含量始终高于子叶和胚轴。

The study was done to understand the first protected wild and critically endangered aquatic fern in China-Isoetes sinensis and to provide more detailed proof about its artificial propagation and emigrate protection. The germination rate of megaspores were statisticed through aseptic culture of spores for rapid propagation in I.

为进一步了解中国一类保护的水生极危野生植物中华水韭以及在大量人工繁殖和迁地保护等方面提供更为详实的证据，运用无菌培养、快速繁殖的方法对中华水韭的大孢子萌发率作了统计，探讨了不同温度对其大孢子萌发的影响。

The results showed that mild alkali stress (pH 6.0~6.5) promoted plant growth, while severe high pH inhibited both seed germination, photosynthesis and root elongation.

结果表明：pH值过高会抑制种子萌发；随着pH值的逐渐增加，根的相对生长量和幼苗叶绿素含量均呈现先增加后减少的趋势；同时，根尖生长素含量随着pH值升高呈现先增加后减少的趋势，表明生长素含量变化可能在植物对碱胁迫的响应中，尤其是在根伸长过程中起着重要作用。

Boehmeriae were studied, and the results indicated that the zoospores of P. boehmeriae could be inactivated obviously by irradiating with 30W ultraviolet light 50cm away from the culture dishes tested and that 95% germination of zoospores could be restrained by 30W ultraviolet light treatment for 40sec.The mycelium growth from mycelium discs of P. boehmeriae were inhibited mostly by 30W ultraviolet light treatment for 20min. Afterwards, the inhibitive rates were decreased with the rise of the treatment time, which showed that the mycelium discs of P. boehmeriae had produced flexibility to ultraviolet rays after being irradiated by certain dosage of ultraviolet light.

研究了紫外光对苎麻疫霉生物学特性的影响，结果表明，30W的紫外灯管距培养皿50cm照射处理对苎麻疫霉的游动孢子具有明显杀灭作用，紫外光照射40sec可以抑制95%的游动孢子萌发；紫外光照射20min对菌丝块的菌丝生长的抑制率达最大，以后随着处理时间增加，抑制率却有降低的趋势，说明苎麻疫霉的菌丝块，经一定剂量紫外光照射后对紫外线产生了适应性。
