小麦根系生长发育的研究日益受到研究者的重视,例如许多研究者用树脂玻璃管栽培法,同位素示踪法等研究不同品种类型根系生长发育对产量的影响,并试图将根系的生育特征作为改良产量的一个参数。本试验是使用遮光的方法降低光照强度,以研究小麦苗 Researches have been paid more and more attention on the growth and development of wheat root system. For example, many researchers studied the effects of root growth and development on the yield of different varieties by resin-glass tube cultivation and isotope tracing methods. A parameter of production. This experiment is the use of shading methods to reduce light intensity to study wheat seedlings
