加工番茄果实发育动态研究初报

研究了加工番茄果实生长发育规律,为生产栽培中采取合理措施来提高果实产量和品质提供科学依据。试验选用里格尔87-5、新引98-1为试材,研究了果实的纵、横径增长和果实鲜重的变化规律。结果表明,两个品种的果实生长发育动态呈“快—慢—快”的“S”型曲线,整个发育期大致可分为3个时期,即果实第一次快速生长期、果实缓慢生长期和果实第二次快速生长期。其中第二次生长量比较明显,两个品种均达到了总量的50%以上。

Preliminary Research on Growth Dynamic of the Processing Tomato

This article has studied fruit growth rhythm of the processing tomato, and offered the scientific basis for developing the yield and quality of the fruit in the practical production. Taking Legel87-5 and Xinyin98-1 as the material, the changes rule of the fruit vertical, the transverse diameter and fresh weight were studied. The results showed that two varieties'' growth dynamic assumes "quick - slow - quick" "S" curve, and the entire development period may be divided into 3 stages approximately--first fast growth period, slow growth period and second fast growth period. Among of the above, second fast growth stage showed obvious growth, two varieties have achieved above 50% of growth in the stage.
