| 要旨本文 | To examine the effectiveness of long rooted seedlings (LRSs) for the dryland plantation, we raised seedlings of three indigenous dry forest species in Kenya (Vachellia tortilis, Dalbergia melanoxylon, Melia volkensii) in M-StAR containers with different depths (15, 30 and 60 cm depth) and compared the growth traits and field performance. Seedlings in deeper containers showed statistically greater growth both in shoot and root biomass at the end of nursery stage for all species. Seedlings of D. melanoxylon and M. volkensii raised in the deepest containers maintained the highest survival rate (>70 %) until the end of first drought season, even though they were planted at the beginning of drought season and were watered only once at outplanting. These results suggest that the LRSs could be a useful technique for dryland restoration. |
