以中国柽柳和管花肉苁蓉为材料,研究了多效唑对柽柳生长和柽柳-管花肉苁蓉物质分配的调控作用。多效唑喷施试验结果:1)降低了柽柳株高,降低范围为7.9%~12.2%。2)提高了柽柳叶片的总叶绿素含量和净光合速率,升高幅度分别为19.4%~70.4%和19.0%~69.4%。3)增加了柽柳干物质向管花肉苁蓉的分配比例,管花肉苁蓉单株生物量增加8.2%~35.9%。4)当多效唑浓度为1.0~2.0g/L时,管花肉苁蓉中非结构性碳水化合物的含量和累积量均高于对照。5)多效唑适宜喷施浓度为:1.5~2.0g/L。结果表明,多效唑具有通过抑制柽柳徒长、提高柽柳光合速率和增加柽柳同化物向管花肉苁蓉的分配而提高管花肉苁蓉生物量的作用。
Chinese tamarisk and Cistanche tubulosa were used as materials to study the effects of paclobutrazol on the growth of Tamarix and the regulation of Tamarix spp. Paclobutrazol spray test results: 1) reduce tamarisk plant height, reducing the range of 7.9% to 12.2%. 2) The total chlorophyll content and net photosynthetic rate of Tamarix chinensis increased by 19.4% -70.4% and 19.0% -69.4%, respectively. 3) increased the proportion of dry matter of Tamarix asarum to the proportion of Cistanche tubulosa, and the biomass per plant of Cistanche tubulosa increased by 8.2% -35.9%. 4) When the concentration of paclobutrazol was 1.0-2.0 g / L, the content and accumulation of non-structural carbohydrates in C. sinensis were higher than those in the control. 5) Paclobutrazol spray suitable concentration: 1.5 ~ 2.0g / L. The results showed that paclobutrazol could increase the biomass of C. fortunei by restraining the growth of Tamarix elongatus, increasing the photosynthetic rate of Tamarix sibirica and increasing the distribution of Tamarix invagination.
