The treatment of GL significantly stimulated rooting number and range, which was more effective than that of ABT, so was the combined treatment of GL and IBA. However, compared with GL, ABT and ABT + IBA could increase root fresh weight and root length. The rooting number and range of adventitious roots in cutting of some woody plants(eg. Carmona microphylla and Glyptostrobus pensllis) were markedly increasing by the treament of GL (250 mg/L) in comparison with ABT treatment. On the contrary, ABT(250 mg/L) caused a remarkable increase in percentage of rooting for adventitious roots by comparison with GL reagent.展开更多

The nutrient solution with three pH levels, Le., 5.0, 7.0 and 8.5 were applied to culture five combination seedlings, including A （RB85-5156 × YR05-407）, B （YR06-3501 ×Tolodo）, C （YT94-128 × GZ75-65）, D （ROC6 × YR05-733） and E （VMC87-95 ×YR05-171）. The result indicated that root length, root surface, root volume and root diameter were all in the largest in B combination with solution pH= 7.0, and the root length, root surface, root volume were in the largest in combination A, C, D and E with solution pH=8.5. Root activity in combination C, D and E were in the highest with solution pH=5.0, while it was in the highest for combination B when pH=7.0. In general, the root growth and morphology in all five combinations were better in the solutions with pH of 7.0 and 8.5.展开更多
