摘要: 利用草莓(Fragaria×ananassa Duch.)生长期内的气温和日照时数观测资料,采用偏最小二乘回归分析、线性回归分析等方法,分析了草莓果实鲜重、果形指数、果实硬度和可溶性固形物含量与日平均气温、日平均最高气温、平均昼夜温差、日平均最低气温及日照时数相关性。结果表明,日平均气温、日平均最高气温、平均昼夜温差和日照时数是影响草莓果实鲜重、果形指数、果实硬度和可溶性固形物含量的重要因素,日平均最低气温是非重要因素。日平均气温、日平均最高气温、平均昼夜温差与草莓果实鲜重、果形指数、果实硬度以及可溶性固形物含量呈负相关;日照时数与果实鲜重及硬度均呈多项式关系。较高的气温和较长的日照时数使草莓横径增长速度加快,较早达到最大值。利用偏最小二乘回归模型进行草莓果实鲜重、果形指数、果实硬度和可溶性固形物含量的模拟效果较好,其中果形指数的模拟结果最好,NRMSE仅为0.03%。

关键词: 草莓(Fragaria×ananassa Duch.), 果实特征, 气温, 日照时数

Abstract: Based on the observation data of temperature and sunshine hours during the growth period of the strawberry, the correlation between fresh weight, fruit shape index, fruit hardness and soluble solids content of strawberry and daily average temperature, daily average maximum temperature, average temperature difference between day and night, average daily minimum temperature, and sunshine hours was analyzed by partial least square regression analysis and linear regression analysis was carried out. The results showed that daily average temperature, daily average maximum temperature, average temperature difference between day and night, accumulated temperature and sunshine hours were important factors affecting strawberry fruit fresh weight, fruit shape index, fruit hardness and soluble solids content, and daily average minimum temperature was not an important factor. The daily average temperature, daily average maximum temperature and daily average temperature difference between day and night were negatively correlated with strawberry fruit fresh weight, fruit shape index, fruit hardness and soluble solids content. The relationship between sunshine hours and fruit fresh weight and fruit hardness was polynomial. Higher temperature and longer sunshine hours accelerated the growth rate of strawberry transverse meridians and reached the maximum earlier. The simulation effect was good when the partial least squares regression model was used to simulate the fresh weight, fruit shape index, fruit hardness and soluble solids content of strawberry fruit. The simulation result of fruit shape index was the best, and NRMSE was only 0.03%.

Key words: strawberry(Fragaria×ananassaDuch.), fruit characteristics, air temperature, sunshine hours
