  叶色
    Several types of leaf color mutants were obtained by using 60 Co γ gamma rays treatment on dry seeds of maintainer long te fu B. In M 2 generation, the mutation frequencies of albino, yellowing and striping mutation lines at seedling stage were 0.347%, 0.041% and 0.031%, respectively.

Several types of leaf color mutants were obtained by using 60 Co γ gamma rays treatment on dry seeds of maintainer long te fu B. In M 2 generation, the mutation frequencies of albino, yellowing and striping mutation lines at seedling stage were 0.347%, 0.041% and 0.031%, respectively. Investigations on their growth dynamics revealed that the average leaves and tillers of the whole yellowing and striping mutation lines were different from the original parent, but some mutants could recover to normal green at three leaf stage, and their leaves and tillers were similar to that of the control. In M 4BC 1 populations, there were two types of leaf phenotype segregation: normal green plants and the plants with leaf color marker, and their segregation were all about 1∶1. According to the characteristics of leaf color expression at seedling stage and later growth stage, these mutant lines in M 4 generation were classified into 6 types. Observations on the plant height, No. of panicles per plant, No. of total grains per panicle, seeds set per panicle and pollen fertility of M 4 mutant lines and plant height and No. of panicles of corresponding M 4BC 1 plants were conducted, the results showed that the agrinomical traits of those lines, which could recover to normal green, and corresponding M 4BC 1 plants with leaf color marker were similar to that of the corresponding control.

用60Co-γ射线直接辐照龙特甫B干种子,诱发获得了多种类型叶色突变体。M2 代按苗计,白化、黄化和条纹三种叶色突变体的频率依次为0.347% ,0.041% 和0.031% 。对M2 代黄化和条纹两类突变群体的生长发育动态研究发现,其平均叶片数和分蘖数与对照有较大的差异。但有一些黄化和条纹突变体在三叶期后即可转为绿色,其叶片数和分蘖数与对照相近。在用这些叶色突变体与龙特甫A 杂交、回交后的M 4BC1 群体中,分离出正常绿色和带有叶色标记的两类不育株,二者之比接近1∶1。根据苗期和成株期的叶色特征,这些突变系分为 6 种类型。对M 4 突变系的株高、单株穗数、每穗总粒数、每穗实粒数和结实率及相应的 M4BC1 植株的株高和单株穗数进行了考察,发现转绿型突变系及其相应的M4BC1 带叶色标记植株的农艺性状与相应的对照相仿。

The precision of digital measurement of plane is higher, degree of accuracy is different acconding to the measure project.The beeline and angle, degree of accuracy at the time of measurement are higher, the errors that are produced relate to length of measurement、 distance and sensitization mode.

The precision of digital measurement of plane is higher, degree of accuracy is different acconding to the measure project.The beeline and angle, degree of accuracy at the time of measurement are higher, the errors that are produced relate to length of measurement、 distance and sensitization mode. The longer the length of beeline measurement is,the less the error is. The sensitization mode is suitable for more than 2048*1530 at the time of angle measurement.For measurements of curve and area, the error is greater at the time of measurement. The error was related with the performance and controlling of mouse with.But the degree of accuracy of area measurement can reach very high level. Color measurement has nothing to do with mode of sensitization, The degree of accuracy is influenced by the distance of digital measurement, The distance should keep 150 cm at least. Digital measurement can reflect accurately the daily cnanges of crops in aspects of beeline、angle and color.The leaf color can be recorded digital.

平面数字测量的精确度较高,准确度因测量项目的不同而不同。直线、角度测量时的准确度较高,所产生的误差与测量长度、距离和感光模式有关。直线测量的长度越长误差越小。角度测量时感光模式以2048×1530以上为宜。曲线、面积测量时误差较大,误差与鼠标的操控和性能有关,但面积测量的准确度可以达到很高的水平。颜色测量与感光模式无关,但受测量距离的远近影响,数据采集时最少应保持150cm以上的距离。数字测量可以准确地反映农作物在直线、角度和颜色方面的日变化,对叶色可以以数字方式进行记录。
