In the present report, we described the effects of indole-3-acetic acid (IAA), zeatin (ZT), gibberellin (GA3), and abscisic acid (ABA) on in vitro pollen germination and pollen tube growth in Torenia fournieri L. The results showed that IAA and GA3 stimulated in vitro pollen tube growth, ABA inhibited pollen tube growth, and ZT had no significant effect on the process. The stimulating effect of exogenous IAA was particularly distinct, and led to synchronous growth of straighter and more slender… CONTINUE READING
