The average values of the stomatal index in the non - leaf organs in ca cereals were smaller than those of leaves . blanke put forward a new physiological process in fruit , ' fruit photosynthesis ' , and featured with lower stomatal frequency ( blanke , 1989 ) . the results here also showed that the significant lower stomatal frequency on non - leaf organs , indicating that the new physiological process might exist in these organs of cereals as well 其中小麦芒和颖片有发育较好的叶绿体结构，其基粒数可达普通叶的水平，但比旗叶少；外稃和穗轴都有完整的基粒跺叠，只是跺叠的数量较少；而内稃基粒少，基粒内囊体跺叠不整齐。

Bud is produced in both rhizome and tiller - node , rhizome can produce more buds than tiller - node on hordeum brevisubulatum , arundinella hirta , calamagrostis epigeios , c . rigidula and hierochloe glabra populations . both 1st age rhizome and tiller - node of 1st age tiller are mainly two contributors in importing of bud bank 根茎和分蘖节是芽的主要产生部位，牛鞭草、野古草、拂子茅、硬拂子茅和光稃茅香种群根茎的营养繁殖力比分蘖节强， 1龄根茎和1龄分蘖株分蘖节是芽库输入的主要贡献者。
