摘要:
为了解刨花楠(Machilus Pauhoi)叶片在生长过程中对资源的分配利用及对环境变化的响应特征,探究刨花楠叶功能性状变异的主要影响机制,本研究以江西南昌与福建顺昌两地同质园的1.5年生刨花楠苗木为研究对象,分析种源与同质园环境对其叶面积(LA)、叶干重(LDW)、比叶重(LMA)、叶形态指数(LMI)以及叶组织密度(LTD)等主要叶功能性状变化的影响。结果表明:刨花楠苗木的LA、LDW、LMA、LMI及LTD 等叶功能性状指标受种源及同质园土壤环境的共同影响,且同质园土壤环境对苗木叶功能性状影响的贡献高于种源(LA性状除外);种源地气温是影响刨花楠种源间苗木叶功能性状变异的主要因素,其中LA主要受种源地7月气温影响(P < 0.01),LDW和LMI主要受种源地年均温影响(P < 0.01),LMA和LTD则分别受种源地纬度和1月气温影响(P < 0.01);土壤养分是影响同质园间苗木叶功能性状差异的主要因素,除LA性状在两同质园间无明显差异外,3种源苗木的叶功能性状指标值均以江西南昌同质园为大;苗木LA主要受种源地环境或遗传基因影响,LDW、LMA、LMI及LTD等叶功能性状指标则主要受同质园土壤养分高低影响;苗木LA、LDW、LMA、LMI及LTD 等叶功能性状指标的表型可塑性指数以LTD最大(0.96),LA最小(0.53),表明苗木不同叶功能性状对种源和同质园环境的响应并不一致。研究结果可为刨花楠优良种源选择、苗木高效培育等提供指导。(图2 表3 参38)
Abstract:
In order to understand the resources allocation and utilization and the response to environmental changes during the growth of Machilus Pauhoi leaves, and explore the main influencing mechanism of the variation of functional traits of Machilus Pauhoi, 1.5-year-old of Machilus Pauhoi seedlings were studied. We compared the differences of leaf area (LA), leaf dry weight (LDW), leaf mass per area (LMA), leaf morphology index (LMI) and leaf tissue density (LTD) between two common gardens in Nanchang, Jiangxi province and Shunchang, Fujian province, and analyzed the effects of provenance and common garden environment on the functional traits of Machilus Pauhoi leaves. The results showed that provenance and the soil environment of the common garden jointly affected the leaf functional traits such as LA, LDW, LMA, LMI and LTD of Machilus Pauhoi seedlings, and the contribution of the soil environment of the common garden to the functional traits of seedlings was higher than that of the provenance (except for LA). The temperature of provenance was the main factor affecting the variation of functional traits of Machilus Pauhoi seedlings among different provenances. LA was mainly affected by the provenance temperature in July (P < 0.01), and LDW and LMI were mainly affected by the annual average temperature of the provenance (P < 0.01). LMA and LTD were affected by the latitude and the provenance temperature in January (P < 0.01). Soil fertility and nutrients were the main factors affecting the differences of functional traits between two common gardens, except that there was no significant difference in LA between the two common gardens. The leaf functional traits of seedlings in Nanchang common garden were the largest among three provenances. LA was mainly affected by the provenance environment or genetics. Leaf functional traits such as LDW, LMA, LMI and LTD were mainly affected by soil fertility and nutrients in common gardens. The phenotypic plasticity index of leaf functional traits was the largest in LTD (0.96) and the smallest in LA (0.53), indicating that the different leaf functional traits of seedlings responded differently to the provenance and common garden environment. The results can provide guidance for the excellent provenance selection and efficient breeding of Machilus pauhoi seedlings.? ? ? ? ? ? ? ? ? ? ? ? ? ?
