The results showed that use of KT,6-BA or CPPU on harvested broccoli delayed floret yellowing and chlorophyll degradation,decreased respiration and ethylene production rate,postponed climacteric time,and retarded membrane permeability loss.

结果表明:3种细胞分裂素类生长调节剂处理均在不同程度上延缓了青花菜花蕾黄化和叶绿素分解,推迟了呼吸和乙烯跃变峰出现的时间,降低了峰值,并维持了细胞膜稳定性。

Then it is dried at 80C, which overcomes the yellowing of common one in the case of heat and long time storage.

它是用有机酸的乙醇-水溶液进行处理，然后在80℃、一定压力下干燥而制得的，能够克服普通水溶性纸受热或长时间存放会返黄的缺点。

The level of lipid peroxidation was the lowest and the peroxidase activity was the highest when the comparative moisture of yellowing period was 80-85%.3.

不同变黄湿度调控下,以变黄期相对湿度80-85%的各装烟密度处理膜脂过氧化水平最低,过氧化物酶活性最高。

But the 2D resin exists two big disadvantage : yellowing and big formaldehyde releasing.

但2D树脂存在泛黄和甲醛释放量大的缺点。
