作者利用“日本晴等21个水稻栽培品种研究了水稻再生能力与抗倒伏性之间的关系。试验于1980年在香川大学农场进行,5月14日播种,6月17日移栽,密度3×9寸,插单本。微随机区组设计,二次重复种植,每次重复栽插150株。从抽穗期开始,每隔10天,连续5次记载与倒伏有关的4个性状,即节间重、茎基部重、茎秆折断力和倒伏指数。节间重,茎基部重和茎秆折断力在抽穗后头10天增加,抽穗后10-20天或20-30天表现下降;但在抽穗后40天又达到或超过抽穗期的水平。倒伏指数在抽穗后30天以前增加,然后下降。还分5个不同生育时期,即抽穗期,抽穗后10、20、30和40天于地面以上5厘米处割掉
The authors studied the relationship between rice regenerative ability and lodging resistance using 21 rice cultivars such as Nipponbare etc. The experiment was carried out on the farm of Kagawa University in 1980, sown on May 14, transplanted on June 17, and the density was 3 × 9-inch, insert the single. Micro-random block design, the second repeated planting, planting 150 plants each repeat from the beginning of heading, every 10 days, recorded in 5 consecutive lodging-related four traits, The weight of stems, the breaking force of stems and the lodging index.The internode weight, stem base weight and stem breakage force increased in the first 10 days after heading and decreased 10-20 days or 20-30 days after heading, 40 days after heading reached or exceeded the level of heading stage.The lodging index increased 30 days before heading and then decreased.They also divided into 5 different growth stages ie heading stage and 10, 20, 30 and 40 days after heading Cut off more than 5 cm
