In Vitro Pollen Germination of Teak (Tectona grandis)

Different concentrations of sucrose and boracic acid were designed for In vitro germination of teak pollen at room temperature, and the effects were studied, and the germination process was also analyzed. The results showed that boracic acid could facilitate the germination of teak pollen significantly, and a satisfactory medium for pollen germination of teak was achieved in a liquid medium supplemented 200 g·L^-1 of sucrose and 200 mg·L^-1 of boracic acid. The pollen germinated after incubating for 1.5 hours, and the pollen germination rate and pollen tube length became stabilized after 5 hours and 10 hours, respectively.
