马铃薯品质好坏主要决定于其淀粉含量的多少。就目前资料所知,国内马铃薯淀粉含量一般为12-20%,国外先进水平达22-44%。本文就马铃薯某些植物学性状与淀粉含量的关系予以探讨。一、材料和方法供试材料为“华741”和“777-96”两个自选品种。于8月30日播种,每小区按初选的不同发芽数(1、2、3、4、5根)分别播种,每小区播5行,共75株,行株距为2.0×0.5尺。出苗后,再选长势比较一致的植株,作为初选的测定对象(每小区30-
Potato quality is mainly determined by how much its starch content. As far as the current information is concerned, the domestic potato starch content is generally 12-20% and the foreign advanced level reaches 22-44%. In this paper, some of the botany characteristics of potato and starch content to be discussed. First, materials and methods The test materials for the “Chinese 741” and “777-96” two optional varieties. Sowed on August 30, each district according to the primary election of different germination number (1,2,3,4,5 root) were sown, each cell sowing 5 lines, a total of 75 lines spacing of 2.0 × 0.5 feet. Emergence, re-election more consistent growth of plants, as the primaries of the measured object (30-
