| This study was designed to investigate the relationships of cations to the polar regeneration of adventitious buds on midvein segments of poplar leaves. Basal regeneration was disturbed by adding $Ca^{2+}$. When higher concentration of exogeneous $Ca^{2+}$ was added to the WPM (Woody Plant Medium), the more adventitious buds were formed on midvein segments, and polar regeneration was inhibited. Added $Ca^{2+}$ from 0 to 9.70 mM with 0.5 mM of EGT A to WPM decreased the calcium effect. The treatment of $La^{3+$ with 7.05 mM of $Ca^{2+}$ ovecame the effect of $Ca^{2+}$. The cations $Mg^{2+};and;K^{+}$ also caused regeneration on both basal and distal site. However, polar regeneration was maintained in the medium containing $Ca^{2+}$ without $Mg^{2+}$. The above result suggests that exogenous $Ca^{2+}$ or cations inhibit polar regeneration of poplar.poplar. |
