Abstract
Taking cultivated Pinus tabulaeformis Carr in Changchun as a case study and the pollen dealed in two conditions as test ma-terials, the effects of sucrose and boric acid with different concentrations in medium on pollen vitality are observed, the results show that on the medium containing agar only, the vitalities of storage 2a ( -18℃) and fresh pollen are respectively 52. 6% and 89. 2%;When sucrose concentration is 10%, the vitalities are respectively 60. 9% and 94. 3%, higher than other concentrations; When the concentration of boric acid is 0. 01%, the vitalities are respectively 78. 9% and 95. 9%, higher than other concentrations; On the combination medium of 10% of sucrose concentration and 0. 01% of boric acid concentration, the vitalities are the highest, respectively reach 81. 2% and 98. 6%, the effect of the combination of the two is better. The reaction trend of stored pollen and fresh pollen on the culture medium with different compositions and concentrations is the same, but the vitality of fresh pollen is higher than that of stored pollen, being sensitive to sucrose and boric acid content.关键词
