采用琼脂床法种子萌发试验研究了五氟磺草胺对不同品种水稻种子萌发及幼苗生长的影响。

Respiration was the most important limiting factor of fresh seed dormancy. Seeds without seed coat and aleurone layer germinated, but could not grow to normal seedling until finishing some metabolism. Drying could break fresh seed dormancy, but the effect of treatment with GA3 and H2O2 was not very significant.

呼吸是限制玉米鲜种子萌发的主要因素，去除种皮可以促使鲜种子萌发，但若要成长为正常幼苗还需体内代谢完成与幼苗生长有关的物质的合成，干燥可以使种子解除休眠，赤霉素、过氧化氢处理可一定程度解除鲜种子休眠，低温处理对解除玉米鲜种子休眠不起作用。

分析经透析后的浸出液表明，马铃薯浸出液中仅高分子物质对游动孢子萌发和附着胞形成具有促进作用，而洋葱浸出液中高分子和低分子物质均抑制游动孢子萌发和附着胞形成。

The hyphae of root rot pathogen for Rhodiola sachalinensis can grow well from 20℃ to 30℃, pH 5. The conidiophore can burgeon very well from 25℃ to 35℃, pH 5 of the culture mediums in which include juice of Rhodila schalinensis, barm, glucose and cream of beef.

The bacteriostatic effects, action mechanisms and antimicrobial spectrum of the strains were tested. After 5 days of culture, a bacteriostatic belt of 6.9-9.67 mm in width was observed on the culture plate, and the inhibitory activity maintained for 10 d. Prefiltration fermentation of the strains P1 and P5 could significantly inhibit conidial germination of the pathogen, with inhibitive rate ranging from 97.51% to 98.12%. The action might be realized by inducing hyphal deformity, bioplasm concentration, conidial germination inhibition and distorting germ tubes of conidia.

通过对其抑菌效果、机制和抗真菌谱进行测定，结果表明，P1、P5和葡萄灰霉病菌对峙培养5 d后，均产生明显的抑菌带，抑菌带宽度为6.90～9.67 mm，培养10 d后，仍然保持稳定的抑菌效果；P1、P5的发酵原液对葡萄灰霉病菌孢子萌发具有显著的抑制作用，抑制率为97.51%～98.12%；P1、P5对病菌的作用机制表现为使病菌菌丝畸形、原生质浓缩、菌丝断裂、抑制病菌分生孢子的萌发、导致孢子芽管扭曲。

The results showed that the suitable temperature for spore germination was 25℃, 2% glucose and Bonar's culture solution obviously increased the germination rate of spores.

对大秃马勃Calvatia gigantea和脱皮马勃Lasiosphaera fenzlii的孢子萌发进行了不同温度、不同营养物及浓度和光照等条件对其孢子萌发影响的研究。

Sinensis, Effects of temperature on the megaspores' germination rate were compared and discussed. Result shows the highest germination rate is about 47%, after megaspores were cultured for 8~10 weeks under 4℃ for 5 days beforehand and then grows under 20℃ with light.

结果显示：中华水韭大孢子的萌发率在培养后第8~10周达到高峰，最高萌发率为47%，最佳萌发条件为低温4℃预处理5d后20℃恒温光照培养。

The survival rate was from 19.7% to 26.0%.(2) Selecting oospores which were produced by 22 isolates crosses, some isolates crosses with higher oospores germination rate were found.

2对22对菌株组合产生的卵孢子进行了萌发试验，通过筛选找到了具有一定萌发率的菌株组合，发现了不同菌株组合产生的卵孢子的萌发率不同。

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。
