作者对葡萄原始材料圃几种品种排列方法作了较详细的论述和评价。作者认为按材料起源排列是最理想的排列方法。在农业生物学和经济学性状方面,作者结合我国实际情况,提出了葡萄成熟期的划分方法和产量高低的分级标准。在植物学性状研究方面,作者认为仅按纵径来衡量果穗、果粒大小的方法是不恰当的,而计量果穗、果粒大小,应同时记载纵径、横径和重量;并提出了按重量的分级方法。无核葡萄由于种子败育或无种子,果粒小,另列了一个分级标准。在记载果实颜色、果皮厚度、肉质、甜酸度等方面,作者也提出一些补充和修改意见。
The author of the grape raw material nursery several species arrangement method made a more detailed discussion and evaluation. The author believes that the arrangement of the origin of the material is the best arrangement. In agricultural biology and economic traits, the author put forward the grading methods of grapes ripening stage and the grading standards of the output level according to the actual situation in our country. In botany study, the author thinks that it is not proper to measure the size of fruit and ear only by the vertical length, but measure the length and diameter of the fruit and the size of the fruit at the same time. Weight grading method. Seedless grapes due to seed abortion or seedless, fruit small, another set a grading criteria. In the records of fruit color, pericarp thickness, meat quality, sweetness and acidity, the author also made some additions and amendments.
