在高产品种选育中人们十分注意理想株型问题,但这一概念通常限定在植株的地上部分。由于阴阳离子交换量是植株根部的特性(Huffarker 等,1959),故在培育高产品种时也应考虑根系的理想型。这应以根系的功能和形态来描述。为此进行本试验,以了解高粱不同基因型根系能力的遗传基础。
In the breeding of high-yield varieties, people pay great attention to the ideal plant type, but the concept is usually limited to the aerial part of the plant. Since the amount of anion and cation exchanges is characteristic of plant roots (Huffarker et al., 1959), the ideal root system should also be considered when breeding high-yielding varieties. This should be described by the function and morphology of the root system. To do this experiment, to understand the genetic basis of sorghum root capacity of different genotypes.

“最近老是睡不好,真烦人。”现代社会,不少人都为失眠所困。科学家们也一直在孜孜不倦寻找扰乱我们睡眠的“罪魁祸首”。最新的研究结果是:我们的身体里,有一种和睡眠相关的基因,如果这种基因缺失,就会产生睡眠障碍。 这则消息让人没法淡定了:“失眠居然是因为基因出了问题,那还能治吗?”“既然是基因的问题,那会不会遗传啊?我的老爸老妈经常失眠,那我以后是不是也会失眠啊?” 先别急,来听听研究者是怎么说的。
