Abstract

To investigate the ecological, yield, physiological, and biochemical index of cultivated pinellia under different shade conditions and to analyze the influence of light intensity on Pinellia ternata’s ecological and physiological characteristics, our experiment employed four varieties of pinellia, Changde pinellia, Yuanling pinellia, Ziyang pinellia, and Bijie pinellia, as experiment materials, planted them under equivalent growing conditions, and placed them under different shade conditions (shade net settings of 0%, 25%, 50%, and 75% shade). The present study sought to determine the index changes of pinellia, including their morphology, photosynthesis, antioxidant enzyme activity, and yield, over a 100-day growth period. The results under 25% shade, compared with full light, revealed the following: pinellia plants reached heights of up to 20.04 cm, an increase of 43.35%; the maximum leaf area was 16.15 cm2, an increase of 34.78%; and the fresh weight of pinellia tubers decreased to varying degrees. Under shade treatment, the content of chlorophyll in pinellia leaves increased, the content of soluble protein and malondialdehyde decreased, and the activities of three antioxidant enzymes increased; these changes were overall consistent with the typical characteristics of shade plants, and the adaptability of pinellia to different shade conditions varied considerably. Moderate shade (25%–50% shade) could improve the physiological and ecological indicators of pinellia and reduce the threat of intense light exposure, but it would also reduce the tuber yield to varying extents
不同遮荫条件下半夏的生态生理特性
并将它们放置在不同的遮荫条件下(遮荫净设置为0%,25%,50%和75%)。本研究旨在确定半夏在100天的生长过程中,其形态、光合作用、抗氧化酶活性和产量等指标的变化。在25%遮荫条件下,与全光照条件下相比,半夏植株最高可达20.04 cm,长高43.35%;最大叶面积为16.15 cm2,增加34.78%;半夏块茎鲜重有不同程度下降。遮荫处理下,半夏叶片叶绿素含量升高,可溶性蛋白和丙二醛含量降低,3种抗氧化酶活性升高;这些变化总体上符合遮荫植物的典型特征,半夏对不同遮荫条件的适应性差异较大。适度遮荫(25% ~ 50%遮荫)可以改善半夏的生理生态指标,降低强光照射的威胁,但也会不同程度地降低块茎产量
