补充资料:月季 玫瑰 蔷薇“三姊妹”的区别(图)
玫瑰 |
蔷薇 |
月季 |
月季和玫瑰的枝条较为直立(也有少数月季是蔓生的)。月季茎干低矮、玫瑰轻干粗壮。蔷薇植株较高,但茎干轻长,枝条蔓生或攀缘。
月季和蔷薇的茎刺较大且一般有钩,每节大致有3~4个;月季的新枝是紫红色;玫瑰的茎密布着绒毛和如针状的细硬刺且茎呈黑色。月季的小叶一般为3~5片,叶片平展光滑;蔷薇的小叶为5~9片,叶缘有齿,叶片平展但有柔毛;玫瑰小叶也为5~9片,但叶片下面发皱,叶背发白有小刺,整个叶片也较厚且叶脉凹陷。
月季一般为单花顶生,也有数朵簇生的,一般为1~3朵,花径约5厘米以上,花柄长且月月季季开花不败,故称月月红、月季花、长春花。蔷薇花常是6~7朵族生,为圆锥状伞房花序生于枝条顶部,花径约3厘米,每年只开一次。玫瑰花单生或1~3朵簇生,花柄短,花茎与蔷薇花大致相同,也只在夏季开一次花,但玫瑰花的香气要比月季、蔷薇浓郁很多。
另外,月季与玫瑰在花谢后萼片均不脱落,而蔷薇的萼片就会脱落;月季与蔷薇的果实为圆球体,玫瑰是扁圆形的果实。
通过以上对月季、玫瑰和蔷薇从枝条、茎、叶片到花、萼片及至果实的区别与比较,大家已经能分出这蔷薇科大家族中的“三姊妹”了吧!
