From the point of view of structure,bamboo cell wall ratio,amount of bundle per unit area,fraction of bundle sheath,fraction of vessel increase from the root to the top of the bamboo,while fractionof parenchyma.Single bundle sheath area decreases with the increase of height.Fiber length,fiber width and vessel length increase from the root to the top andget theirs maximum value at the length of 17th node to 23rd node and thendecrease.Fiber length and width ratio slightly decreases while vessel widthincreases with the increase of height.

从构造角度来说，竹材胞壁率、单位面积维管束个数、纤维束比量、输导组织比量从基部到到梢部随着高度增加而增加，而薄壁组织比量、单个维管束纤维束面积随着高度增加而减小；纤维长度、纤维宽度、导管长度从基部到梢部随着高度的增加而增加，在第17竹节到第23竹节达到最大值，而后下降，纤维长宽比随着高度的增加而缓慢下降，导管宽度随着高度增加而一直增加。

From the point of microstruction,bamboo volume fraction of bundlesheath,single bundle sheath area,fiber width,cell wall thickness increase withthe growth of age,fraction of cell wall changes like density,increases with thegrowth of age,the 2 age-degree bamboo is the biggest.The reason why 2 age-degree fraction of cell wall more than 3 age-degree bamboo is the former has thegreater fraction of parenchyma;1 age-degree bamboo has the greatest fiberlength,fiber length and width ratio and vessel length.The difference in bamboofiber length,vessel length and width among other age-degrees is not distinct.

从构造角度来说，竹材的纤维束比量、单个维管束纤维束面积、纤维宽度、胞壁厚度随着年龄的增大而增大，胞壁率随年龄变化规律与密度相似，随年龄增大而增大，以2度竹最大，2度竹胞壁率比3度竹大主要由于薄壁组织比量较大所致；纤维长度、纤维长宽比、导管长度以1度竹最大，其它年龄纤维长度、导管形态变化不明显。

Using image processing technology, we analyze the size and shape of cell wall crystal region of bamboo's cross section during entire growth from bamboo shoot to the mature bamboo. Using region segmentation, we study the forming and distributing characteristic of crystal regions of the fiber cap、 proto-sieve 、 thin-walled cell of vascular bundle of bamboo's cross section.

It is found that some tissues of Asparagus whose sense quality and thin cell wall tissues around gas cavity have been influenced under the various processing condition through the experiments.And all these changes are related with the heating time,temperature and being frozen.

通过实验可知在各种加工及冷藏条件下，芦笋的感官质量与组织结构中的表皮、薄壁组织、导管等均会受到影响，而且与加热时间的长短、温度的高低及是否受冻有密切的关系。
