摘要：柚木（Tectona grandis L.f.）是世界名贵的用材树种,天然分布于印度、缅甸、泰国和老挝,具有生长快、用途广、纹理美观和价格昂贵的特点,已在热带、南亚热带地区广为引种,是世界上人工林种植面积最大的4个树种之一,也是单位面积产值最高的一个造林树种。
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.
