Ultrastructural changes in secondary wall formation of phyllostachys pubescens Mazel fiber were investigated with transmission electron microscopy. Fiber developed initially with the elongation of cells containing ribosomes, mitochondria and Golgi bodies in the dense cytoplasm. During the wall thickening, the number of rough endoplasmic reticulum and Golgi bodies increased apparently. There were two kinds of Golgi vesicles, together with the ones from endoplasmic reticulum formed transport vesicles. Many microtubules were arranged parallel to the long axis of the cell adjacent to the plasmalemma. Along with the further development of fiber, polylamellate structure of the secondary wall appeared, with concurrent agglutination of chromatin in the nucleus, swelling and disintegration of organelles, while cortical microtubules were still arranged neatly against the inner side of plasmalemma. Lomasomes could be observed between the wall and plasmalemma. The results indicated that the organelles, such as Golgi bodies together with small vesicles, rough endoplasmic reticulum and lomasomes, played the key role in the thickening and lignification of the secondary wall of bamboo fiber, though cortical microtubules were correlative with the process as well.

Ⅰ、引言 1979年7月24日生长在京都大学Kamigamo实验林站的24株毛竹全都开花。同时,生长在Yokohama500m~2上的200株毛竹也发生了。这二块竹林由MAEDA1912年采收的种子萌发而培育出同一无性系构成的。两块竹林同时开花,对论述毛竹开花周期提供了一个很有趣而又有价值的记载。从毛竹种子培育到开花记载在日本确实是第一次被承认,即使其他竹种也很少记载。

毛竹笋体的生长极其迅速,在快速生长阶段,日平均生长量为35—50厘米,在高峰时可达1米(熊文愈,1962)。但出土的毛竹笋不是全部都能生长成竹,不成竹的笋称为退笋(退败),约占出笋的50％,除部分为虫害所致外,生理退笋占很大比例。本文从生... 详细信息

毛竹笋体的生长极其迅速,在快速生长阶段,日平均生长量为35—50厘米,在高峰时可达1米(熊文愈,1962)。但出土的毛竹笋不是全部都能生长成竹,不成竹的笋称为退笋(退败),约占出笋的50％,除部分为虫害所致外,生理退笋占很大比例。本文从生理角度来研究毛竹笋体的生长和退败与内源生长调节物质的关系,为减少或克服生理退笋提供参考。

The height growth of bamboo in 2008 and 2009 as well as the water contents of bamboo stump,leaves,straw,and rhizome in 2009 were measured at the Tianmu Mountain Nature *** results revealed that the relationship between the height growth（Pn）and growth time（t）showed S-shaped curve in the two years;the water contents of bamboo stump,leaf,straw,rhizome and bamboo shoot were 0.50-2.31,0.46-1.8,0.50-1.38,0.56-1.58 and 0.89-8.96,*** them,the water content of bamboo shoot was the highest and noticeable changed,followed by bamboo stump,leaves,rhizome and straw in *** water contents of the underground and aboveground parts respectively were 0.34-0.62 and 0.33-0.57.

Winter bamboo shoots are widely used in Asian cuisine. We surveyed growth depth （tail depth and root depth）, harvest speed, and harvest processes to provide information for developing new harvest technology. The tail depth of most winter bamboo shoots was 100 350 mm below the soil surface, and the root depth was 200 500 mm below the soil surface. Most winter bamboo shoots were difficult to locate with only the naked eye. The digging depth was 200 500 mm to cut winter bamboo shoots from the root. The highest harvest rate was 7.75 times faster than the slowest one and the average harvest speed ratio of men： women was about 1.71：1. The harvest process of winter bamboo shoots was divisible into three steps： searching, digging a hole （around the shoot） and cutting the root. The ratio of searching time to the sum of digging and cutting time was about 8：1, showing that searching required more time than digging and cutting together.
