不同生长期和光照条件下红果参果实的生长动态

Study on Dynamic Changes of Cyclocodon lancifolius Fruit Under Different Growth Periods and Light Conditions

通过考察不同生长期和光照条件的红果参果实动态变化,为红果参合理采收期的确定和人工栽培光照条件的选择提供科学依据。对不同生长期和光照条件下红果参鲜果的外在品质及内在品质指标进行测定,并进行相关性分析。结果表明,红果参果实在无遮阴光照条件下品质最佳。总体上看,从10月开始,随着采收时间后延,果实大小、单果重、可溶性固形物、可溶性糖、总酸、维生素C均有不同程度的增加,果实硬度逐步降低,其中多数指标在1月上旬达到最佳,故确定1月上旬为最佳成熟采收期。本研究基本探明了红果参的栽培光照条件及果实最佳成熟采收期,可为红果参规范化种植提供理论参考。

By investigating the dynamic changes of Cyclocodon lancifolius fruit in different growth periods under light conditions,it provides a scientific basis for the determination of the reasonable harvest period of C.lancifolius and the selection of artificial cultivation light conditions.The external quality and internal quality indexes of C.lancifolius fresh fruit under different growth periods and light conditions were measured and the correlation analysis was carried out.The fruit quality of C.lancifolius was the best under the condition of no shading light.In general,from October,with the delay of harvest time,fruit size,single fruit weight,soluble solids,soluble sugar,total acid and Vc all increased to varying degrees,and fruit hardness gradually decreased.Most of the indicators reached the best in early January,so early January was determined as the best mature harvest period.This study basically proved the cultivation light conditions and the best harvest time of C.lancifolius,which laid a theoretical foundation for the standardized planting of C.lancifolius.
