摘  要:
用3年生未结果火棘作为实验材料,探讨赤霉素(GA3 )、多效唑(PP333 )、6 -苄基腺嘌呤( 6 -BA)、比久(B9 )对火棘盆景春梢的生长调控。结果表明,以上生长调节剂不同的质量浓度PP333 300mg/L、PP333 500mg/L、6-BA200mg/L、B9 800mg/L对火棘春梢生长量、冠幅、叶面积都有不同程度的抑制作用,经PP333 300mg/L、PP333 500mg/L、B9 800mg/L处理过的叶厚度、叶绿素含量都高于或接近于对照。以上处理都改善了火棘的株型,提高了火棘盆景的观赏价值,应用灰色系统理论综合评价证实这些处理是比较理想的。

摘  要:
The optimal concentrations of GA_3、PP_(333)、6-BA and B_9 for the regulation of the growth of spring shoots and their effects on comprehensive quality were investigated with 3-year-old no-fruit Pyracantha fortuneana(Maxim.) Li. The results showed that PP_(333) 300 mg/L,PP_(333) 500 mg/L,6-BA 200 mg/L and B_9 800 mg/L were effective in controlling the biomass, crown and leaf area of the spring shoots. The leaf thickness and content of chlorophyll of the spring shoots treated with PP_(333) 300 mg/L,PP_(333) 500 mg/L and B_9 800 mg/L were closed to and higher than those of the control. They all improved the shape and ornamental value of Pyracantha fortuneana(Maxim.) Li. Data analysis using the gray system theory indicated that the treatments above were relatively ideal.
