stomata number 中文意思是什麼
stomata number
解釋
氣孔數-
The results indicated that ( 1 ) " longxianhuosuan " presented more regular and more densely - arranged epidermal cells in its scapes than " gailiangsuan " ; ( 2 ) " longxianhuosuan " showed a lower stomata number but a larger stomatal aperture in its scape surface than " gailiangsuan " ; its scapes had a great number of secretory cells, which had a larger size and appeared earlier ; its scapes presented a smaller number of vascular bundles with smaller diameters ( 3 ) " longxianhuosuan " had polygonal cells in its scape pith with their intercellular space occupying a small proportion while " gailiangsuan " showed elliptical cells in its scape pith with their intercellular space occupying a high proportion
結果表明： （ 1 ） 「隴縣火蒜」比「改良蒜」蒜薹的表皮細胞形狀規則，排列緻密；角質層較薄； （ 2 ） 「隴縣火蒜」比「改良蒜」蒜薹表面的氣孔數量少，但開張度大；分泌細胞出現早、體積大、數量多；維管束數量少、直徑小； （ 3 ） 「隴縣火蒜」蒜薹髓細胞衛多邊形，髓細胞間隙率小，而「改良蒜」蒜薹的髓細胞呈橢圓形，髓細胞間隙率大。 -
The plasma membrane h + - atpase is involved in many important physiological functions, including cell elongation, stomata movement, stress responses and cellular responses to a number of factors such as plant regulators, light and fungal toxins
因此，質膜h ~ + - atpase活力受激素、光、植物毒素、環境脅迫等外部和內部因子的影響。有人認為h ~ + - atpase可能是激素直接作用的靶分子。 -
2 leaflets from plants grown in the increasing salt concentrations ( up to 200mm ) became smaller and thicker, leading to the smaller ratio between superficial area and mesophyll tissue volume. in the same process, the cuticle became thickness significantly increased while stomata became less in number and smaller in area
（ 2 ）隨鹽濃度增加，葉片整體逐漸變得小而厚，葉表面積與體積的比值小，從而減少蒸騰面積，同時角質層變厚，單位面積上的氣孔數目減少，氣孔器面積減小，都可以使植物盡量降低蒸騰速率，減少體內水分散失。 -
Subsidiary cell ( accessory cell ) one of a number of specialized epidermal cells of a plant that are found adjacent to the guard cells, and may help in opening and closing the stomata
副衛細胞：是特化了的植物表皮細胞的一種，緊鄰保衛細胞，在植物氣孔的開閉過程中起一定作用。
