摘　　要：为了探索‘圣心芒’果实在百色的生长发育规律,测定其生长周期果实体积的变化,并结合果实生长节点的生长情况和营养需求,做到科学用药、用肥,通过构建果实体积线性回归估算公式,利用估算公式进行果实非离体体积矫正,以Logistic生长模型为基础,应用数学方法建立‘圣心芒’果实生长发育回归方程。结果表明,构建的体积估算公式线性回归关系极显著,能够估算出‘圣心芒’的体积;‘圣心芒’果实纵径、横径和果实体积的回归方程均为Logistic的单“S”曲线,其中横径、纵径和果实体积分别在第30天、第26天和第47天取得最大生长速率,整体上纵径的生长发育周期比横径短6d,果实体积到达最大生长速率比横径和纵径晚20d,对应的速生期起始点t1和终止点t2都延后,表现为生长速率函数图象收缩后移。相关结果适用于对‘圣心芒’果实生长发育动态变化规律的描述,为‘圣心芒’在百色芒果产区高产优质栽培技术体系研究提供数据依据。In order to explore the fruit growth and development pattern of'Sensation'mango in Baise,the changes of fruit volume during its growth cycle were determined,which was to achieve the goals of proper use of fertilizers and pesticides combining with the growth status and nutritional requirements of fruit growth nodes.By constructing a linear regression estimation formula for fruit volume and using the estimation formula to correct non-in-vitro fruit volume,a regression equation for the growth and development of the'Sensation'mango fruit was established using mathematical methods based on the Logistic growth model.The results showed that the constructed volume estimation formula had a significant linear regression relationship and could estimate the volume of'Sensation'mango.The regression equations for the longitudinal diameter,transverse diameter and fruit volume of'Sensation'mango were all logistic single"S"curves.The maximum growth rates for transverse diameter,longitudinal diameter,and fruit volume were obtained on the 30th,26th and 47th days,respectively.Overall,the growth and development cycle of longitudinal diameter was 6 days shorter than that of transverse diameter,and the maximum growth rate of fruit volume was 20 days later than that of transverse diameter and longitudinal diameter.The corresponding starting point t1 and ending point t2 of the rapid growth period were delayed with a contraction and backward shift in the production rate function graph.The relevant results were applicable to the description of the dynamic changes in the growth of'Sensation'mango,and provided data basis for the research on high-yield and high-quality cultivation technology system of'Sensation'mango in Baise.
