| 【目的】探究光照强度对粗肋草生长、叶色及叶片花色素苷、叶绿素相对含量的调控作用，分析其对光胁迫的生理响应，为粗肋草的栽培与应用提供理论依据。【方法】以‘吉利红’‘中国红’‘东方红’‘如意’‘红颜’5个粗肋草品种的一年生幼苗为试验对象，设置低（600-900 lx）、中（1 000-2 500 lx）和高（2 500-7 700 lx）3种光照环境，分别测定幼苗生长指标（株高、单株生物量等）和生理指标（叶色、花色素苷含量、抗氧化酶活性等）。【结果】①在高光照 环境下，所有粗肋草品种的株高、生物量等生长指标均最佳，植株最健壮。②光照越强，粗肋草叶色越深，斑纹越艳丽； 多数品种的花色素苷含量随光照增加而升高；不同品种的相对叶绿素含量（SPAD值）对光照强度的响应不尽相同， ‘吉利红’和‘如意’SPAD值随光照增强先升后降，‘东方红’‘中国红’‘红颜’SPAD值随光照增强持续上升。③各品种适应光强的能力不同。‘吉利红’‘东方红’MDA含量随光照增强而升高，‘中国红’和‘红颜’随光照增强先升后降， ‘如意’则随光照增强而降低。‘吉利红’在高光照环境下的抗氧化酶（POD、SOD）活性最高且抗性强，其他多数品种则 在中等或低光照环境下抗氧化酶活性更高，能适应弱光环境。【结论】粗肋草生长及观赏性在高光照强度（2 500-7 700 lx）下最佳，推荐在光照充足的环境下种植，但应避免强光灼伤或过度遮阴，以实现生长与观赏效益最大化。 |

| Abstract: |
| 【Objective】This research aims to investigate the regulatory effects of light illuminance on the growth，leaf color，leaf anthocyanins，and relative chlorophyll content of Aglaonema modestu，and analyze its physiological responses to light stress，to provide a theoretical basis for the cultivation and application of A.modestum.【Method】Using one-year-old seedlings of five A.modestum varieties，including‘ Jilihong’，‘Zhong-guohong’，‘Dongfanghong’，‘Ruyi’ and‘ Hongyan’ as the experimental subjects，three lighting conditions （low：600-900 lx，medium：1 000-2 500 lx，and high：2 500-7 700 lx） were set.And growth indicators （plant height，biomass，etc.） and physiological indicators（leaf color，anthocyanins，enzyme activity，etc.） of seedlings were measured.【Result】① Under high light conditions，all varieties showed the best growth indicators，including plant height and biomass per plant，and the plants were the strongest. ②The stronger the light，the darker the color of the leaves，and the more vibrant the patterns. The content of anthocyanins in most varieties increased with increasing light exposure. Different varieties exhibited varying responses in their relative chlo‐
rophyll content（SPAD value） to light illuminance.The SPAD values of‘ Jilihong’ and‘ Ruyi’ first increased and then decreased with increasing light illuminance，while those of‘ Dongfanghong’，‘Zhongguohong’ and ‘Hongyan’ continuously increased with increasing light illuminance. ③ Different varieties exhibited varying adapting capacities to light illuminance. The MDA levels of‘ Jilihong’ and‘ Dongfanghong’ increased with increasing light illuminance，whereas those of‘ Zhongguohong’ and‘ Hongyan’ first increased and then decreased with increasing light illuminance，and those of‘ Ruyi’ decreased with increasing light illuminance. Three varieties，including‘ Jilihong’，experienced the most severe cell membrane damage under low light conditions，whereas all varieties exhibited the least damage under high light conditions.‘Jilihong’ showed the highest antioxidant enzyme（POD，SOD） activity and strong resistance under high light conditions. Other varieties mostly showed higher enzyme activity under moderate or low light conditions，with adapting ability to low light condition.【Conclusion】The growth condition and ornamental value of A. modestum are optimal under high light illuminance（2 500-7 700 lx）.It is recommended to cultivate A.modestum in environments with sufficient light，while avoiding strong light scorching or excessive shading，so as to maximize growth and ornamental benefits. |
