分枝水稻的来源和类型 1953年夏季,在上海的北郊发现了大量的分枝大麦,接着在秋收時又发现了大量的分枝水稻。作者把從国营上海新市農場採集來的分枝水稻作了分析(水稻的品種是木樨球),發現分枝的類型有下列4种: 1.單枝型:一般從莖稈下部第二或第三葉腋间分出(以根颈处为第一節)。這種類型最多,分枝上所抽的穗子较大,穀粒也很充實,故這種類型很有價值。 2.双枝型:從第二第三,或第三第四,或第二第四节葉腋间分出。分枝所抽的穗子也較長大,穀粒也很充實,故以此種類型为最好,但較第一種为少。 Sources and Types of Branched Rice In the summer of 1953, a large number of branching barley was found in the northern suburbs of Shanghai, followed by a large number of additional branching rice at the fall harvest. The authors analyzed the branching rice collected from the state-run Shanghai Xinshi Farm (the variety of rice is the clogs) and found the following four types of branching: 1. Monaxial branches: usually from the second or The third leaf axillary separation (root neck section for the first quarter). This type is the most abundant on the branches pumping the ears, grain is also very substantial, so this type is very valuable. 2. Twig type: from the second third, or third fourth, or second fourth leaf axillary separation. Branches pumping the ears are also more grown, grain is also very substantial, so this type is the best, but less than the first.
