准确测定玉米种子的发芽率对玉米生产、销售非常重要。通过对玉米种子发芽率鉴测技术的研究,探索出了一套成熟的玉米种子发芽率鉴测技术程序。本研究采用对山东省莱州市55个玉米品种进行发芽率测定试验的方法,总结出了玉米种子发芽率鉴测方法和程序:①分析了玉米种子发芽率鉴测的材料选用和方法,介绍发芽箱、沙等材料的选择,分析了发芽方法;②对研究的结果与分析进行了阐述,对幼苗鉴定方法、发芽试验检测结果内容填写、种子数据处理和差距表使用、重新试验等进行了具体分析,介绍了具体的操作方法。通过这种鉴测方法对莱州市55个玉米品种种子发芽率进行鉴测,种子发芽率98%达到了国家标准,经鉴测的品种在全国得到了大面积推广。主要按GB/T3543、1-3543、7-1999中华人民共和国国家标准,测定发芽率,现将1个指标,即发芽率的鉴测程序论述如下:随机取出4个品种,通过对莱州登海种业、金海种业、金来种业及鲁单981的测试,测试结果登海3号为99%;金海5号为99%;金来玉5号为93;鲁单981为91%。都通过了国家标准。
Accurate determination of the germination rate of corn seed production and sales of corn is very important. Through the research on the germination rate of corn seed, we have explored a set of mature germination rate detection technology program of corn seed. In this study, 55 maize varieties in Shandong Laizhou City, the determination of germination rate test methods, summed up the corn seed germination rate detection methods and procedures: ① analysis of corn seed germination rate of the material selection and methods to introduce germination Box, sand and other materials, and analyzed the germination methods; ② The results and analysis of the study were described, the seedling identification method, germination test results fill out the contents of the seed data processing and the use of gap table, re-test carried out a specific Analysis, introduced the specific method of operation. The germination rate of 55 maize seeds in Laizhou was tested by this method. The germination rate of seeds reached 98% and reached the national standard. The tested varieties have been widely popularized throughout the country. Mainly according to GB / T3543,1-3543,7-1999 People’s Republic of China national standards, determination of germination rate, now an indicator, that the germination rate of the testing procedures are as follows: Four randomly selected varieties, through the Laizhou Denghai Seed industry, the Gimhae industry, gold to seed industry and Lu Shan 981 test, test results Denghai 3 99%; Jinhai 5 99%; Jinlaoyu 5 93; Ludan 981 91%. Have passed the national standard.
