Abstract

The growth vigor of rubber mini-seedling budding was observed by suspension and near-ground culture with different specifications of root-controlled containers. The results showed that suspension culture had a significant effect on the longitudinal elongation (such as plant height and main root length) of rubber grafted seedlings. When the height of seedling containers was the same, the larger volume of seedling containers, the more extension space of root system and better growth of the seedling’s above-ground part. When the volume was the same, the higher height of seedling containers, the longer length of seedling’s main roots. But there were little influence on the above-ground part of seedlings and the diameter of main roots.
