我们籍汁液注射植物在当年就获得很大变異,现将方法及结果介绍如下,以供参考。一、材料与方法试验材料是選用菸草的两个品种:(一)土耳其(司美娜Smyrna)该品种的特性是较耐旱,早熟,黑胫病及白粉病在潮湿地常易发生,产量低,一般只在100市斤左右,但品质良好;(二)巴黎包皮(Paris wrapper)该品种也稍具有抗旱性,产量高达401市斤,品质好,抗黑胫病力达87.5％,对叶斑病也稍有抗病性。用後者(巴黎包皮)的汁液注射到前者(土耳其)的植株中,以观察它的变異性,处理项目有:
Our membership of juice plants in the year to obtain a great deal of variation, the methods and results are introduced below, for reference. MATERIALS AND METHODS The test materials were selected from two varieties of tobacco: (i) Turkey (Smyrna) This variety is characterized by drought tolerance, precociousness, black shank and powdery mildew in humid areas, where yield Low, generally only about 100 catties, but of good quality; (b) Paris wrapper (Paris wrapper) This variety is also slightly drought-resistant, yield up to 401 jin, good quality, resistance to black shank disease 87.5% Leaf spot is also slightly disease resistant. The latter (Paris foreskin) juice was injected into the former (Turkey) plants to observe its variability, dealing with the following items:
