scalariform 中文意思是什麼
scalariform
解釋
adj. 形容詞 【動物；動物學】梯狀的；【植物；植物學】階紋的。a scalariform vessel 梯紋導管。
-
Vessels solitary with angular outline ; perforation plates scalariform ; intervessel pits and vessel - ray pitting alternate to scalariform ; helical thickenings only in vessel elements tails
導管橫切面為多角形，單管孔，散生。螺紋加厚僅出現導管分子尾端。梯狀穿孔為主。 -
Wood semi - ring - porous ; vessels solitary with angular outline ; perforation plates reticulate and scalariform ; intervessel pits and vessel - ray pitting alternate ; helical thickenings throughout body of vessel elements
單管孔，散生；整個導管分子上具螺紋加厚。網狀和梯狀穿孔。 -
Wood semi - ring - porous ; vessels solitary with angular outline ; perforation plates scalariform ; intervessel pits and vessel - ray pitting opposite or opposite to scalarifonn ; helical thickenings in vessel elements present
梯狀穿孔板；管間紋孔式為互列；射線導管間紋孔式多對列，類似導管面間紋孔式。 -
It was shown that vessel elements in secondary xylem of p. emblica have many different forms and most of them have tails and their perforation plates divide into two types : ( 1 ) there is one simple perforation plate at each end of the vessel elements and ( 2 ) there is one simple perforation plate at one end of the vessel elements and two simple perforation plate at the other end ; ( 3 ) a few vessel elements have special inclusions ; ( 4 ) the intervascular pits are alternate pits ; ( 5 ) the pits between the vessels and rays are mixed pits, pits with transverse gashes and scalariform pits
結果發現，余甘子次生木質部導管分子中存在著許多不同的樣式，導管分子大多數具尾；其穿孔板存在著兩種類型： （ 1 ）兩端均為1個單穿孔板； （ 2 ）一端為1個單穿孔板;另一端為2個單穿孔板； （ 3 ）極少數的導管分子具有特殊的內含物； （ 4 ）管間紋孔式為互列紋孔式； （ 5 ）導管射線間紋孔式為混合型紋孔與橫列刻痕狀紋孔以及梯狀穿孔。
