人们对不同作物的株内变异几乎没有什么了解。在大多需要有若干植株的果实或种子样本的研究中,往往假定株内变异是随机的,因而其效应可相互抵消。可是有报道指出,株内系统变异是存在的,应予重视。Collins和Cartter(1965)从大豆中观察到植株下半部的种
People have little knowledge of intra-plant variation in different crops. In studies of fruit or seed samples that mostly require several plants, it is often assumed that the intraspecific variation is random and therefore their effects can be offset. However, it has been reported that intra-plant system variation exists and should be taken seriously. Collins and Cartter (1965) observed the lower plant species from soybean
