This paper describes an experiment specially designed to test in Chinese fir(Cunninghamia Lanceolata(Lamb. ) Hook) the relation between harvesting season and vigor of sprouting. The investigation included the first budding time, the amount of budding, the dynamics of sprouting and the growth of sprouts. Through statistical analyses of these indexes, the effects of harvest season on sprouting characteristics of the specie were studied.

This paper describes an experiment specially designed to test in Chinese fir(Cunninghamia Lanceolata(Lamb. ) Hook) the relation between harvesting season and vigor of sprouting. The investigation included the first budding time, the amount of budding, the dynamics of sprouting and the growth of sprouts. Through statistical analyses of these indexes, the effects of harvest season on sprouting characteristics of the specie were studied. The research also determined the optimal harvest season for a Chinese fir stand, and the time to be reproduced by sprouts.

通过不同季节采伐试验,获得杉木伐桩休眠芽始萌发期、萌发量、萌发动态及越冬萌条生长状况的数据。经统计分析,揭示了采伐季节对杉木休眠芽萌发特性的影响,并进一步确定了杉木林萌芽更新的适宜采伐季节和最佳采伐季节。

Structural and organizational changes of the vegetative cell in Amaryllis vittata Ait. during such dynamic processes of pollen as hydration, activation and germination have been examined with electron microscopy. The mature pollen grain is composed of such organelles as plastids, mitochondria,endoplasmic reticulum, dictyosomes and lipid bodies which are in their resting state.

Structural and organizational changes of the vegetative cell in Amaryllis vittata Ait. during such dynamic processes of pollen as hydration, activation and germination have been examined with electron microscopy. The mature pollen grain is composed of such organelles as plastids, mitochondria,endoplasmic reticulum, dictyosomes and lipid bodies which are in their resting state. Microfilaments appear as aggregates. After pollen activation, however,the organelles undergo great changes in number and shape: the lamellae of plastids and the cristae of mitochondria increase conspicuously in number, the cisternae of the endoplasmic reticulum become narrower; the dictyosomes produce vesicles actively the lipid bodies become degraded and the microfilament aggregates disperse. Cortical microtubules and spiny vesicles appear in the cytoplasm after germination of the pollen tube. No apparent structural changes of the organelles were noticed any longer during this period and microfilaments are distributed throughout the entire pollen tube as a three-dimensional network.

本文应用透射电镜对朱顶红成熟花粉水合、活化和萌发的动态过程中营养细胞质的结构和组成变化进行了观察。成熟花粉具质体、线粒体、内质网、高尔基体。微丝束以聚集体的形式存在。花粉活化后,细胞器的数目和结构发生显著变化:质体和线粒体的片层明显增加,内质网片层狭窄,高尔基体活跃产生小泡,脂体降解及微丝聚集体散开。花粉萌发后,细胞质中出现周质微管和被刺小泡,此期细胞器的变化不明显。微丝以纤丝状遍布整个花粉管中。

Objective To study dynamics and affecting factors of bulbil germination in Pinellia ternata for directing application and elucidating developmental biology of bulbil. Methods The dynamics of bulbil germination and effects of bulbil size, planting deep, soil humidity, and different sources on bulbil germination and seedling growth were studied using completely randomized experimental design. Results(When bulbil) of P. ternata from Nanchong County, Sichuan Province started to germinate for about 14 d after planting, germination rate was up to 60% at 23 d after planting and it ended to germinate at after planting. Germination rate of bulbil in diameter ≥8 mm was higher than that in diameter 5—8 mm. Effects of two kinds of planting deep (10 and 20 mm) on bulbil germination and seedling growth were not significant. However, the germination rate of bulbil in humidity-kept soil was higher than that in drought-threatened one. From the planting through 23 d, the bulbil germination rate of P. ternata from Nanchong County, Sichuan Province was significantly higher than that from Xinjiang County, Shanxi Province. Subsequently, the difference of their bulbil germination rate was not significant. In addition, it was discovered that the shape of leaves varied when bulbils of P. ternata from different sources germinated. Conclusion It is very important for propagation and production of P. ternate to develop the larger bulbil and to keep soil humidity. Furthermore, bulbil of P. ternata from different sources possesses different characters of germination and growth, so research and choice on the source and lines of P. ternata should be regarded in their production.

目的研究半夏P inellia terna ta珠芽的萌发动态及其影响因子,为阐明半夏珠芽的生产应用和珠芽发育生物学提供依据。方法利用完全随机实验设计研究半夏珠芽的萌发动态以及珠芽大小、不同覆土深度、土壤干湿度和不同来源对半夏珠芽萌发和半夏生长的影响。结果四川南充半夏珠芽播种约14 d开始萌发,23 d萌发率达60%以上,29 d完成萌发。直径≥8 mm的珠芽的萌发率显著高于5 mm≤直径<8 mm的珠芽;两种覆土深度10和20 mm对半夏珠芽的萌发和半夏幼苗的生长没有显著性影响;保持土壤湿润的珠芽萌发率显著高于土壤见干见湿的珠芽;从播种到23 d时,四川南充半夏的珠芽萌发率极显著高于山西新绛半夏的珠芽,随后二者的萌发率没有显著性差异。另外发现不同来源的半夏珠芽在萌发时叶形会发生变化。结论培育大的珠芽对半夏繁育有重要意义,保持土壤湿度对提高萌发率和促进半夏幼苗生长有重要作用,不同来源的半夏珠芽具有不同的萌发特点和生长特性,应重视半夏不同品系的筛选。
