The stomatal density and stomatal index had little taxonomical significance among the six genera.However, the two characters might be useful for species identification. 氣孔密度和氣孔指數在屬間的分類(lèi)意義不明顯,但在屬內種間的分類(lèi)上具有一定價(jià)值。
The results showed that the ploidy level had a significantly positive correlation with the stoma diameter, but a negtive correlation with the stoma density. 結果表明,紅掌倍性與氣孔長(cháng)度呈顯著(zhù)正相關(guān),而與氣孔密度呈顯著(zhù)負相關(guān)。
