在相同条件下，从稻田直接收集的病粒中的稻粒黑粉病菌厚垣孢子不能萌发，而取之于仓库中的孢子能萌发。为探明其制约因素，对该病菌进行了光照和浸水时间试验。研究结果表明：稻粒黑粉病菌冬孢子形成后，必须经光照射后，方可进入休眠期；度过5～6个月休眠期的冬孢子，必须浸水48h以上才开始复苏；复苏后的冬孢子必须在光照条件下才能萌发。未完成后熟作用的冬孢子和完成后熟但尚未复苏的冬孢子即使在光照条件下也不能萌发。即稻粒黑粉病菌冬孢子必须经历后熟、休眠、复苏三个阶段后，在适宜的光照与温湿条件下，方可萌发。光照对其冬孢子具有双重作用，促使后熟进入休眠和刺激萌发。 相似文献

Experiments consisted of three phases: spore production, spore storage and spore germination. Throughout the experiments temperature was near-optimal. In each phase various light and humidity treatments were given. The time at which a spore germinated was considered to be a stochastic variable. 3,000 lux inhibits germ tube elongation measurably; 7,600 lux inhibits germination measurably. Spores produced in darkness are more sensitive to light than spores produced in light, independent of the age of the pustules. Hydration of spores during storage increases light-sensitivity during germination. Samples of spores formed in darkness at low humidity are considered to consist of three sub-populations: a light-insensitive one presumably having profited from the foregoing light period, a light-sensitive sub-population and a group of spores which is inert or dead. The light-inhibited spores germinate rapidly after being placed in darkness with a germination rate little affected by the duration of light exposure. After four hours of light-exposure a gradually increasing proportion of the light-inhibited spores is killed, which means that the reversibility of the light-inhibition is limited. 相似文献

Inhibitory and promotive allelopathy in rice (Oryza sativa L.) 总被引：2，自引：1，他引：2
Studies on allelopathic rice, which inhibits the germination and development of weeds such as barnyardgrass ( Echinochloa spp.) and ducksalad [ Heteranthera limosa (Sw.) Wild.], have been strongly conducted in the USA, the Philippines, Japan, Korea, and other countries since the 1980s. Weed-suppressing rice plants can compete with weeds for light and mineral nutrients by their rapid and thick growth characteristics, and probably also by their allelopathic effects. It was suggested that allelopathic properties were inherited from parents. Different screening methods for finding allelopathic rice simply and rapidly have been proposed. In contrast, stimulative allelopathy in rice, which promotes germination of the dormant and dormancy-awakened seeds of Monochoria vaginalis (Burm. f.) Kunth var. vaginalis , has been investigated by the authors since the 1990s. Rice seeds promoted the germination in the dark and in light under submerged conditions. Our experiments suggested that rice seeds, hulls, plants and straw contain stimulative substance(s) that promote seed germination of M. vaginalis . 相似文献

ZJUF0986活性代谢产物对稻瘟病菌致病性的影响 总被引：2，自引：1，他引：1
通过菌丝生长速率法和悬滴法测定ZJUF0986活性代谢产物对稻瘟病菌菌丝生长、孢子萌发和附着胞形成的影响。结果表明,ZJUF0986活性代谢产物对稻瘟病菌菌丝生长的有效中浓度EC50为18.55mg/L,与对照药剂三环唑的EC50(17.30mg/L)相比无显著性差异。活性代谢产物不仅影响孢子萌发,也显著降低附着胞的形成。浓度为10mg/L的活性代谢物可完全抑制孢子萌发及附着胞的形成;浓度为1.25mg/L时则明显延缓孢子萌发及附着胞的形成,处理48h后的孢子萌发率和附着胞形成率分别为62.17%和38.46%。以浓度为1.25mg/L活性代谢产物处理的稻瘟病菌孢子悬浮液接种离体大麦叶片,病原菌孢子在大麦叶片表面能部分萌发形成附着胞,但侵染栓形成延迟,致病性明显降低。 相似文献

When detached broad bean leaves were preinoculated with virulent strain B304 of Botrytis cinerea 24 h before a challenge inoculation with strain B304, lesion formation by B304 was significantly inhibited in red light but not in the dark. In leaves that were preinoculated with avirulent strain 021 and then challenged by B304, however, lesion formation was not inhibited even under red light. Such differences in lesion formation after the challenge inoculation with an avirulent strain were also observed with lesions caused by Alternaria alternata, a nonpathogen of broad bean and by avirulent strain 021R in the presence of germination fluid from spores of strains B304 and 021R. These results suggest the possibility that virulent B. cinerea produced a suppressor involved in induced susceptibility and an elicitor involved in resistance induced by red light during spore germination. 相似文献

Leptochloa chinensis is a new weed that has been found with increasing frequency in Italian rice paddies. The germination ecology of L. chinensis seeds was studied in order to investigate the development mechanisms and survival strategy of this weed in rice paddies of northern Italy. Leptochloa chinensis seeds showed no dormancy and exhibited germination even in anoxic conditions. Germination was strongly influenced by temperature (minimum around 15°C; optimal 25–35°C) and light (phytochrome dependent). Temperature fluctuation caused an increase of seed germination in the dark. Seed burial also strongly inhibited germination and emergence of this species. At 5 cm seed burial only 5% of seedlings emerged in flooded conditions, while at the same depth, but with no flooding, no seedling emergence was observed. This phenomenon was not due to oxygen depletion, as germination was not inhibited by complete anoxia, as demonstrated by the fact that some seedlings did emerge in flooding conditions when water was no deeper than 6 cm. Seed burial and concomitant flooding induced an unusual germination: first coleoptile emergence and subsequently emergence of the radicle was observed. The possible exploitation of this knowledge for weed management is discussed. 相似文献

The germination of race 1 spores of Fusarium oxysporum f. sp. ciceri was significantly inhibited by the root exudate of the wilt-resistant chickpea cvs CPS1 and WR315 compared to untreated spores and spores treated with root exudates from susceptible cultivars. The effect was concentration dependent, such that the exudate from 1 g of root in 2 ml of water almost completely inhibited spore germination, whereas the exudate from 1 g of root in 20 ml water did not do so. The inhibitory effects of the active exudates were negated when the apolar components of the exudates were removed by extraction with ethyl acetate. The root exudates of the susceptible cv. JG62 and the late wilting cv. H208 did not inhibit germination. The hyphal growth of germinated spores was also strongly inhibited by the concentrated exudates of CPS1 and WR315, and diluted exudates were less potent. The highest concentration of the exudate of the susceptible cv. JG62 showed some inhibition of hyphal growth, whereas none of the exudates of H208 were found to contain any antifungal activity. The effect of the exudates on the spores of race 2 was similar to that reported for race 1, except that the water-soluble components of the crude root exudate of WR315 after ethyl acetate extraction were also found to inhibit germination significantly. Overall, the spores of race 2 appeared to be more susceptible to the effects of the exudates. The ethyl acetate fractions of the root exudates of CPS1 and WR315 strongly inhibited germination and hyphal growth of both race 1 and race 2, the effect being concentration dependent. The results suggest that the resistance of chickpeas to vascular wilt depends, at least in part, upon the antifungal activity of the root exudates. Differences in the expression of resistance in the field could depend upon the concentration or rate of production of constitutive antifungal components by the root. 相似文献

球形赖氨酸芽胞杆菌Lysinibacillus sphaericus（Ls）是应用广泛的蚊虫生物防治制剂，在实际应用时可能会遇到不利的环境因子或杀菌剂。本研究通过单细胞分析方法监测ClO2处理后的单个Ls芽胞及其萌发过程，探究ClO2对Ls芽胞结构和成分的影响及与芽胞萌发相关蛋白的影响，以及ClO2的杀胞机制。经0.05%～0.3% ClO2处理5 min后，36%～86%的芽胞不能形成单菌落。吡啶二羧酸钙（CaDPA）特征峰（1017 cm-1）强度随处理程度增大有所降低，而蛋白质α-螺旋峰（1652 cm-1）强度没有明显变化。ClO2处理显著改变Ls芽胞的萌发动态，芽胞启动CaDPA快速释放的时间、完全释放的时间以及皮层水解完成的时间显著延长；而外源CaDPA仅能触发低浓度ClO2（0.05%）处理的芽胞，且显著迟缓。表明ClO2处理没有直接破坏芽胞内膜但严重损伤了与萌发相关蛋白的功能，特别是皮层水解酶容易失活。这可能就是被处理的芽胞可以启动芽胞萌发的最初步骤，而不能进一步发展为营养细胞的原因。 相似文献

Inoculation of celery plants with viruses CV036 (celery mosaic) and CV506 (parsnip yellow fleck) decreased blight on leaves inoculated later with Septoria apiicola by 17–39% and 54–91%, respectively. There was a significant negative correlation between the amount of blight and the furanocoumarin content of the celery petioles. The antifungal activity of these furanocoumarins was demonstrated by their in vitro inhibition of the germination of spores of S. apiicola and Botrytis cinerea . Scanning electron microscopy of virus-infected leaves sprayed with spores of S. apiicola also showed slight but significant reductions in percentage germination and in germ-tube length, and considerable reductions in the proportion of germ-tubes which produced an appressorium, compared with spores on virus-free leaves. 相似文献

The seeds of Monochoria vaginalis require light to germinate. However, they are able to germinate in darkness in the presence of rice hulls. The mechanism of this phenomenon was investigated in this study, in which only the unsterilized seeds of Monochoria were induced to germinate by the presence of a rice hull extract. The rice hull extract was able to be replaced by either a mixture of amino acids and phosphate or a yeast extract. The culture media in which germination was observed always showed turbidity, indicating the propagation of bacteria, which were identified as Bacillus sp., Pedobacter sp., Pantoea sp. and Sphingomonas sp. Treatment with the individual bacterial species or combinations of these bacteria induced Monochoria seed germination when added to the media containing the rice hull extract. It was concluded that the rice hull extract accelerates the propagation of bacteria, which in turn digest the seed coat of Monochoria, facilitating its germination. 相似文献
