摘要/Abstract

摘要：

分析了胡杨(Populus euphratica)叶片幼叶期、发育期、成熟期的阔卵圆形叶、卵圆形叶、披针形叶生物量、面积、体积与叶柄生物量的异速生长关系,基于叶片水平探讨胡杨不同叶形叶片对资源分配随发育阶段变化。结果表明:(1)幼叶期3种叶形叶片生物量、叶片面积、叶片体积与叶柄生物量间相关性不显著。(2)发育期阔卵圆形叶片生物量与叶柄生物量存在异速生长关系,卵圆形叶片生物量、叶片面积及叶片体积与叶柄生物量间存在异速生长关系。(3)成熟期3种叶形叶片生物量、叶片面积、叶片体积与叶柄生物量间均存在异速生长关系。(4)发育期,阔卵圆形叶与卵圆形叶片与叶柄共同斜率均显著大于1,表明发育期叶片增长高于叶柄,植株对叶片投资高于叶柄;成熟期2种叶形叶片与叶柄共同斜率均显著小于1,表明成熟期增加了对叶柄的生物量投资。(5)阔卵圆形叶片与卵圆形叶片与叶柄共同斜率高于披针形叶,说明阔卵圆形叶与卵圆形叶较披针形叶分配更多资源于叶片。

Abstract:

Our objectives are to determine allometric relationships between lamina mass, area, volume and petiole mass in different leaf developing processes of three types leaf of Populus euphratica, namely broad ovate leaf, lanceolate leaf and ovate leaf, to explore leaf level resource utilization strategy of P. euphratica across ontogenetic stages. The lamina mass, area, volume and petiole mass were measured in early stage, intermediate stage, late stage of development of P. euphratica leaf. The standazed major axis estimation method was used to examine the scaling relationship among leaf traits of P. euphratica. The results showed that:(1) there was no significant relationship between lamina mass, area, volume and petiole mass at the early stage of development; (2) there were significant allometric relationships between lamina mass of broad ovate leaf and its petiole mass, petiole mass of ovate leaf and its lamina mass, lamina area and lamina volume at the intermediate stage; (3) there were significant allometric relationships between lamina mass, lamina area, lamina volume and petiole mass of three types of leaf; (4) common slopes of broad ovate leaf and ovate leaf were >1.0 significantly at the intermediate stage of development and <1.0 significantly at the late stage, which meant that lamina growth rate higher than the petiole, resources investment on lamina was higher than petiole at the intermediate stage, but resources investment of petiole increased at the late stage of development; (5) broad ovate leaf and ovate leaf common slopes significantly higher than lanceolate leaf, which meant broad ovate leaf and ovate leaf invested more resources on lamina than lanceolate leaf.

Key words: allometry, leaf traits, Populus euphratica, lamina, petiole, resource utilization strategy
