Abstract

Abstract: This study was aimed to explore the response of alpine plants to hydrothermal changes and its underlying mechanism. In central Tibet,Nam Tso region between 2016 and 2019,the responses of Astragalus strictus to asymmetric warming (annual warming—ANW and growing season warming—GRW) that simulated by open top chambers (OTCs) were studied. The green-up,senescence,and growing season duration of Astragalus strictus in response to asymmetric warming were analyzed. We found that the mean green-up phenology of Astragalus strictus significantly differed between years. The green-up date in 2019 was significantly advanced compared with other years under all treatment conditions,while the green-up date in 2017 and 2018 was delayed compared to that in 2016 and 2019. On four years’ average,both the ANW and GRW did not significantly affect the green-up,nor did interact with “year” and each other. Based on the data in 2019,the ANW and GRW did not significantly affect senescence or growing season duration of Astragalus strictus,but the average onset time of senescence was delayed 7.7 days on average compared to control. Under the GRW,the onset time of senescence in 2019 was delayed 1.9 days on average compared to control. The average growing season duration of Astragalus strictus was 153 days under the ANW,which was 1.7 days shorter than the control. The average growing season duration under GRW was 140.5 days,which was 14 days shorter than the control one. However,the trend of changes in green-up and senescence under the warming treatments in different years might be related to variation in water availability in natural conditions over the years,where warming caused advancement in green-up,delay in senescence,and lengthened in growing season duration under the warming treatments when water was abundant,while the delayed green-up,advanced senescence,and shortened growing season duration under the warming treatments were caused by the drier soil condition due to warming in the draught years. In conclusion,water availability is one of the most important conditions for plant growth in this region.

摘要： 植物物候是植物为适应其生长环境而呈现的节律性变化,是气候变化的最敏感指示器之一。为了探讨高寒植物对其生长环境水热变化的响应特征和机制,本研究利用开顶式模拟增温装置进行增温,以茎直黄芪(Astragalus strictus Grah. Ex Bunge)为研究对象,探讨其返青、枯黄物候和生长期长度对2016—2019年季节性不对称性增温(全年、生长季增温)的响应特征和机理。研究发现:茎直黄芪的平均返青物候在年际间差异极显著;2019年与其它年份比较显著提前了茎直黄芪的返青物候;增温未影响茎直黄芪返青物候;与对照比较,全年和生长季增温分别延迟了茎直黄芪枯黄期7.7和1.9 d,缩短了其平均生长期长度1.7和14.5 d;在水分充足条件下增温提前植物的返青物候,延长其枯黄物候,导致生长期延长,自然水分条件相对较低时则相反。综上分析,水分条件是该区域植物生长的主要限制因素之一。
