However, the interrelationships and potential influencing networks between rubber latex yield and these factors are rarely quantitatively assessed. Our study was conducted on a state-managed farm in Xishuangbanna; a tropical region of southwestern China. Rubber latex is important to the local economy, yet Xishuangbanna\u2019s climate is considered suboptimal for rubber cultivation, and the powdery mildew disease has become prevalent. Understanding impacts on rubber phenology and latex yield could inform better management practices. Using observational data on daily rubber latex yield combined with detailed phenology, powdery mildew, and climatic data from 2004-2010, we investigated the effects of climate, phenology, and powdery mildew disease on rubber latex yield in March. We found critical influencing periods of daily temperature difference on rubber latex yield occurring in March. Partial Least Square regression analysis and Variance Partitioning analysis were conducted using 35 phenological variables, eight powdery mildew related variables, and two climatic variables. The most influential variables affecting rubber latex yield in March included the following: the duration of leaf flushing phenology (duration of both leaf flushing and leaves turning light green), the mean and maximum percentage of leaves infected by powdery mildew, and the daily temperature differences during Jan-Mar. Subsequent Canonical Correlation Analysis and linear regression found that raised daily temperature differences from Jan-Mar had the greatest impact, causing higher rubber latex yield. This study comprises the first time that a network of intercorrelations consisting of phenology, powdery mildew disease, and climate has been shown to determine rubber latex yield. Our comprehensive quantitative assessment revealed the relative importance of antecedent daily temperature differences, phenology, and powdery mildew disease as well as their complex interconnections in influencing rubber latex yield.<\/p>\n\n\n\n<hr class=\"wp-block-separator is-style-wide\"\/>\n\n\n<p><strong>Speaker: <\/strong>Dr. Zhai Deli<\/p>\n<p><strong>Affiliation: <\/strong>Kunming Institute of Botany, CAS<\/p>\n<p><strong>Time:<\/strong> March<span lang=\"EN-US\"> 29, 2022<\/span><\/p>\n<p><strong>Venue: <\/strong>\u77a9\u76ee\u4f1a\u8bae\u5e73\u53f0 \u4f1a\u8bae ID\uff1a135 871 8714 \u00a0\u4f1a\u8bae\u5bc6\u7801 PWD\uff1a666666\u00a0<\/p>\n<p>\u89c6\u9891\u4e0b\u8f7dDownload Link\u94fe\u63a5: https:\/\/pan.baidu.com\/s\/1xRgE0XeIp4qGBtYKLU5xmA\u00a0 Pwd\u63d0\u53d6\u7801: fx54<\/p>\n<p>\u77a9\u76eeZHUMU <br \/>\u4f1a\u8bae ID\uff1a135 871 8714 <br \/>\u4f1a\u8bae\u5bc6\u7801 PWD\uff1a666666<br \/>\u56fd\u5185\u7528\u6237\u4e0b\u8f7d\u5730\u5740Download address for domestic users\uff1ahttps:\/\/zhumu.com\/download<br \/>\u56fd\u9645\u7528\u6237\u4e0b\u8f7d\u5730\u5740Download address for international users\uff1ahttps:\/\/zhumu.com\/download-intl<\/p>\n\n\n<hr class=\"wp-block-separator is-style-wide\"\/>\n\n\n\n<div class=\"wp-container-1 wp-block-group\"><div class=\"wp-block-group__inner-container\">\n<div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<\/div><\/div>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Speaker: Dr. Zhai Deli<br \/>\nAffiliation: Kunming Institute of Botany, CAS<br \/>\nTime: March 29, 2022<\/p>\n","protected":false},"author":2,"featured_media":2908,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[3],"tags":[],"_links":{"self":[{"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=\/wp\/v2\/posts\/2907"}],"collection":[{"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=2907"}],"version-history":[{"count":1,"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=\/wp\/v2\/posts\/2907\/revisions"}],"predecessor-version":[{"id":2909,"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=\/wp\/v2\/posts\/2907\/revisions\/2909"}],"wp:featuredmedia":[{"embeddable":true,"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=\/wp\/v2\/media\/2908"}],"wp:attachment":[{"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=2907"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=2907"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=2907"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
