日光温室番茄果实鲜重与横纵径数学关系研究

Study on Relationship between Weight of Tomato Fruit and Transverse Diameter and Vertical Diameter in Greenhouse

在日光温室内对长季节栽培的番茄进行破坏性取样及活体定株观测,确定番茄果实鲜重与横纵径间的关系及果实干物质含量。结果表明:番茄果实鲜重与横径、纵径的三次方均呈线性关系,未成熟果果实鲜重与横径、纵径的关系分别为M=0.441×w3和M=0.735×h3;成熟果果实鲜重与横径、纵径的关系分别为M=0.446×w3和M=0.662×h3;夏季和冬季果实横径膨大生长速率分别为0.191cm/d、0.138cm/d;夏、冬季果实纵径膨大生长速率分别为0.131cm/d、0.114cm/d,夏季果实膨大速率高于冬季;温度变化对果实干物质含量形成无明显影响,未成熟果实的干物质含量比成熟果实的稍偏高。

This article is about the relationship between the fresh tomato＇s transverse and vertical diameter and the tomato＇s pure weight. We got sample by broken one kind of long term tomato from greenhouse. We observed the same kind of tomato. Results showed that a linear relationship between the fruit fresh weight and the transverse and vertical diameter cubic. When the tomato is immature, the relationship between the fruit fresh weight and the transverse diameter and the vertical diameter is M=0.441×w^3 , M=0. 735×h^3 respectively, and When the tomato is mature, the relationship is M=0. 446×w^3 ,M= 0. 662×h^3 respectively, the velocity of fruit transverse expanding growth in summer and winter respectively is 0. 191cm/d ,0. 138cm/d and the velocity of fruit vertical expanding growth in summer and winter respectively is 0. 131cm/d,0.114cm/d. The velocity of fruit expanding growth in summer is bigger than in winter. Temperature change can＇t affect fruit dry matter nature content formation obviously, and dry material content of immature fruit is slightly higher than mature fruit.
