The plant of Dendrobium nobile Lindl. is a perennial herbaceous epiphytic orchids. Its specialized pseudobulb used as nutrient storage organ and can be realized in the clonal growth, of which plays an important role in the vegetative propagation. This research studied the wild plant, compared to the difference of sympodial growth and high lateral bud on different levels of pseudobulb, and analyzed the engraftment way. Meanwhile, the adaptive strategy of its growth and vegetative propagation were discussed. Mainly results showed as following: (1) the seedlings grow and expand via vegetative propagation of sympodial. With 2-3 bud in reserve of pseudobulb, it sprouts 1-2 new bud and forms different seedlings as time goes on. (2) The seedlings have typical high lateral reproductive characteristics and mainly form from dense pseudobulb and roots. (3) The stems of high seedlings attach to the tree trunks, shorten the distance and complete engraftment way by stem intenerate and gravity. The results show that the pseudobulb of Dendrobium via sympodial vegetative propagation to enhance and extend lifetime. The adversity such as crowding of pseudobulb respond by frequent high bud germinating, and it is an ecological adaptive strategy of epiphytic environment like engraftment way of high seedlings depending on stem.
