摘要:

以牡丹江地区的白牛槭(Acer mandshuricum)、茶条槭(Acer tataricum subsp. ginnala.)、糖槭(Acer saccharum)、五角槭(Acer pictum subsp. mono)4种槭树为研究对象,分别于春季、夏季和秋季进行取样,测定叶片性状指标(叶厚度、气孔长度、气孔宽度、气孔密度、叶脉密度、比叶面积及色素质量分数),分析叶片各性状的季节变化趋势,并探讨色素与叶性状间在不同季节下的关系。结果如下:(1)4种槭树均表现为在夏季具有较高的叶厚度、较低的比叶面积和气孔密度,在秋季具较高的比叶面积和叶脉密度、较低的叶厚度。(2)4种槭树均为在夏季有较高的叶绿素a、b,在秋季色素质量分数均降低,季节变化区间分别为叶绿素a 77.40%~98.80%,叶绿素b 85.60%~99.53%,类胡萝卜素4.29%~78.52%。(3)色素与叶性状关系密切,季节动态下色素与比叶面积、气孔密度、叶脉密度正相关,与叶厚度、气孔长度、气孔宽度负相关(P<0.05),但不同季节相关性略有差异。4种彩叶植物的叶片在应对不同季节的气候条件时形成了不同的构建策略,其叶片功能性状的变异体现了彩叶植物适应季节变化的权衡机制。

Abstract:

Four species of AcerA. mandshuricumA. tataricum subsp. ginnala., A. saccharumA. pictum subsp. mono)on Mudanjang were selected as materials in spring, summer and autumn, respectively, and the seasonal variation trend of leaf traits(e.g. leaf thickness(TL), stomata length(LS), stomata width(WS), stomata density(DS), leaf vein density(DV), specific leaf area(ASL) and pigment content) were analyzed, and the relationship between pigments and leaf morphological traits in different seasons were explored respectively. The result showed that: (1)Four kinds of Acer species showed higher TL, lower ASL and DS in summer, higher ASL and DV, lower TL in autumn. (2)The chlorophyll a and b of four Acer species were higher in summer, and the pigment content decreased in autumn. Their seasonal variation ranges were chlorophyll a 77.40%-98.80%, chlorophyll b 85.60%-99.53%, and carotenoids 4.29%-78.52%. (3)Pigment was closely related to leaf morphological traits. Under seasonal dynamics, pigments were positively correlated with ASLDS and DV, and negatively correlated with TLLS and WSP<0.05), but the correlations were slightly different in different seasons. The leaf was formed different construction strategies in response to climatic conditions in different seasons in four color species. The variation of leaf functional traits reflected the trade-off mechanism of colored-leaf plants adapting to seasonal changes.

Key words: seasonal dynamics, morphological traits, pigment, colored-leaf plant, correlation
