摘要
以WPM+ZT2.0mg/L为基本培养基,添加不同种类和浓度的PP333、B9、CCC,比较其对越橘试管苗生长的影响,结果表明:PP333、B9、CCC3种生长延缓剂中,10～40mg/L的B9和10～80mg/L的CCC对越橘试管苗具有延缓生长的作用,由此长成的小苗健壮,茎粗叶茂,生根率高。而越橘试管苗对PP333极为敏感,在极低浓度下(0.05mg/L)仍对越桔试管苗的生长产生强烈抑制,并使试管苗生长畸形。
To test effects of PP333, B9 and CCC on tube-plantlets growth of cowberry, we added them at different concentrations respectively to the base medium （WPM＋ZT 2. 0mg/L）. The results showed that B9 （10-40mg/L） or CCC（10- 80mg/L） could slowdown the growth rate of tube-plantlets. After treating with B9 or CCC, the plantlets grew strong, the stem became thickset, and the rooting rate became higher. The tube-plantlets of cowberry were very sensitive to PP333. The growth of tube-plantlets was sorely restrained at very low concentrations of PP333 （0. 05mg/L）, and the tube -plantlets grew abnormally.
