Chin Southern University Agricultural Research and Extension Center, Baton Rouge, LA 70813, USA Journal Article 2016 08 08 <span>UV-B radiation affects crop plants. Growing interest has been shown in studying the effects<br /><span>of UV-B radiation exclusion on crops since 1993. This article summarized the general<br /><span>consequences of UV-B radiation exclusion on crop plants from the aspacts of plant morphology,<br /><span>growth and development. UV-B exlusion has promoting effects on plant height, internode<br /><span>and leaf size. UV-B exclusion increases root biomass and stimulates nodulation of legume<br /><span>crops with increased number and size of nodules and enhances the leghemoglobin. Higher<br /><span>levels of α-tocopherol is found in UV-B plants, which plays an important role in translocating<br /><span>photoassimilates from the leaves to the roots. UV-B exclusion could be a useful tool for<br /><span>physiologists and molecular biologists to further address mechanisms involved in UV-B<br /><span>radiation damage in crop plants.</span></span></span></span></span></span></span></span></span><br /><br class="Apple-interchange-newline" /></span> https://ijpp.gau.ac.ir/article_3048_145bc812df0f4a7d9fcf29676c17f798.pdf
