现代化温室番茄植株各器官鲜物质和干物质分配规律的研究

A Study on the Growth and Development Pattern of Tomato in Modern Greenhouse Long-season Cultivation

试验结果表明 :在本试验条件下 ,番茄植株鲜物质分配到根、茎、叶片和果实中的比例分别约为 1 %、2 0 %、5 0 %和 3 0 % ,干物质分配到根、茎、叶片和果实中的比例分别约为 2 %、2 5 %、47%和 2 6%。果实干重占植株总干重的比例为 2 6% ,果实干重与营养器官干重的比率为 3 4%。植株的平均干物质含量为 1 0 .2 % ,其中果实的干物质含量为 5 .0 % ,叶片、茎和根的干物质含量分别为 1 1 .6%、1 1 .3 %和 1 4.9%。

The experiment showed: the ratios distributed to root, stem, leaf and fruit from fresh matter were approximately 1%, 20%, 50% and 30%, respectively. The ratios distributed to root, stem, leaf and fruit from dry matter were approximately 2%, 25%,47% and 26%, respectively. The ratio of fruit dry matter weight to the total plant dry matter weight is 26%. The ratio of the fruit dry matter weight to vegetative organ dry matter weight was 34%. In the experiment, the average dry matter content of the whole plant was 9.9%, the dry matter content of the fruit is 6.1%, the dry matter contents of the leaf, stem and root were 12.1%, 11.7% and 16.0%, respectively.
