The results showed that: (1) Moderate shading (25%\u201350% light) significantly promoted morphological growth, photosynthetic efficiency, and corm yield in most varieties, while both full light and 7% extreme low light inhibited growth and development, with significant differences in optimal light intensity among varieties. (2) Cluster analysis classified the eight varieties into three functional groups: HMY01 (high photosystem II (PSII) stability), morphology-dominant type (YunRe1701, XD09, GY02, emphasizing plant height and leaf area expansion), and photosynthesis-dominant type (YunRe1707, YunRe1709, YunRe1710, YunRe1726, emphasizing light energy use efficiency). (3) Principal component analysis (PCA) extracted four principal components with a cumulative contribution rate of 81.23%, effectively distinguishing two synergistic dimensions: \u2018light energy utilization and carbon assimilation\u2019 and \u2018morphological construction and pigment adjustment\u2019. This study provides a scientific basis for variety selection and light management in konjac understory intercropping systems.\n                  <\/jats:p>","DOI":"10.3389\/fpls.2026.1931411","type":"journal-article","created":{"date-parts":[[2026,8,24]],"date-time":"2026-08-24T04:24:21Z","timestamp":1787545461000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Effects of shading on morphology, photosynthetic characteristics, and yield of different Amorphophallus varieties"],"prefix":"10.3389","volume":"17","author":[{"given":"Jinwei","family":"Li","sequence":"first","affiliation":[{"name":"Yunnan Institute of Tropical Crops","place":["Jinghong, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenxian","family":"Xu","sequence":"additional","affiliation":[{"name":"Yunnan Institute of Tropical Crops","place":["Jinghong, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Minghui","family":"Chen","sequence":"additional","affiliation":[{"name":"Yunnan Institute of Tropical Crops","place":["Jinghong, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanxiong","family":"Gong","sequence":"additional","affiliation":[{"name":"Yunnan Institute of Tropical Crops","place":["Jinghong, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanwei","family":"Ruan","sequence":"additional","affiliation":[{"name":"Yunnan Institute of Tropical Crops","place":["Jinghong, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zesen","family":"Lai","sequence":"additional","affiliation":[{"name":"Yunnan Institute of Tropical Crops","place":["Jinghong, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruyue","family":"Xu","sequence":"additional","affiliation":[{"name":"Yunnan Institute of Tropical Crops","place":["Jinghong, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huifang","family":"Yuan","sequence":"additional","affiliation":[{"name":"Yunnan Institute of Tropical Crops","place":["Jinghong, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiangshuai","family":"Yan","sequence":"additional","affiliation":[{"name":"Yunnan Institute of Tropical Crops","place":["Jinghong, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,8,24]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"777","DOI":"10.2307\/2259531","article-title":"Light requirements of neotropical tree seedlings: a comparative study of growth and survival","volume":"72","author":"Augspurger","year":"1984","journal-title":"J.
