Two phenomena related to temperature effects have been observed during the induction of betacyanin synthesis by a cytokinin (benzyladenine) in Amaranthus tricolor seedlings. One is a total inhibition of betacyanin accumulation at a temperature (39 C) at which seedling growth is unimpaired, and where there is still adequate uptake of benzyladenine. The other is the apparent induction of a higher potential for subsequent betacyanin synthesis following pretreatment of the seedlings at an elevated temperature.
在用细胞分裂素(苄基腺嘌呤)诱导三色苋幼苗中甜菜色素合成的过程中,观察到了两种与温度效应相关的现象。一种是在某个温度(39℃)下甜菜色素积累完全受到抑制,此时幼苗生长未受影响,且苄基腺嘌呤的吸收仍充足。另一种是在较高温度下对幼苗进行预处理后,后续甜菜色素合成的潜力明显增加。
