Arrow Bamboo (Bashania fangiana) only distrbutes in the western mountains of the Sichuan Province, growing in the mixed forests of coniferous and broadleaf trees and under subalpine needl forest at about 2100—3600 metres above sea level. This kind of bamboo in Qionglai mountains is Giant Panda's staple food. In 1983, Arrow Bamboo was flowering, seeding and dying-off, and the flowered area was about 65 to 95 percent of the total area in which Arrow Bamboo distributed. Aecording to the history, Arrow Bamboo flowers every 50 to 60 years. It will take over 10 years for the seed to become adult bamboo. As a result, the Giant Pandas in this area have a periodic food crisis. Therefore, studying the seed charaeteristics and the regeneration of the seedlings and using some methods to improve their regeneration and rehabilitation are not only the need of the study on its characteristics of bio-ecology, but also strategic measures. for the research, conservation and population development of Giant Pandas. This article describes the characteristics of the seeds of Arrow Bamboos: net percent, water containing, weight of 1000 seeds, living ability, rate of sprout, resting period and life span of the seeds. It also describes the growth of the bamboo seedlings: seed quantity on the ground during the natural regeneration; lasting time of the sprouts; growth of the seedlings; seedling amount trends in the early period of the regeneration; the rate of the living seedlings; and the growth and changes of the seedlings. So the general principles of the life activity of the seeds and the growth of Arrow Bamboo seedlings have been found, providing the Scientific basis for artificial improving Arrow Bamboo's natural regeneration in high mountains.
