stomatal frequency 中文意思是什麼
stomatal frequency
解釋
氣孔頻度-
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
其中小麥芒和穎片有發育較好的葉綠體結構，其基粒數可達普通葉的水平，但比旗葉少；外稃和穗軸都有完整的基粒跺疊，只是跺疊的數量較少；而內稃基粒少，基粒內囊體跺疊不整齊。 -
Characterization of stomatal frequency, stomatal index and guard cell length stomatal characteristics appear to be related to variations in net photosynthetic rate and water - use efficiency ( sellers et al, 1996 ). here, the stomatal frequency, the guard - cell length and the stomatal index of non - leaf organs were investigated comparatively between the ear and the leaf of wheat. the results showed that stomatal frequency of non - leaf organs is significantly lower than that of leaves, whereas the guard - cell length and stomatal index showed different variation patterns in both leaves and non - leaf organs
另外，本文還著重討論了非葉器官氣孔頻度對作物光合作用的影響，並提出了在非葉器官中可能存在與此相適應的未知的光合類型葉綠體是作物進行光合作用的場所，通過對小麥、水稻非葉器官及功能葉葉綠體超微結構的比較研究，發現非葉器官單個光合細胞中葉綠體的數量較少，體積也較小。
