영문 초록

In order to study the hybridity and origin of Populus glandulosa, the pollen tree of Populus alba×P. glondulosa, the variation of morphological characteristics and rooting abillity of Populus glandulosa were compared with those of P. tomentosa, P. davidiana and P. albs. The morphological characteristics, such as leaf length and width, petiole, leaf pubescence, gland of leaf base and stomata were investigated and global morphological comparison among these species was carried out by canonical discriminent analysis. Based on the morphological characteristics, P. tomentasa appeared to be intermediated of P. alba and P. davidiana, and P. glandulosa appeared to be the intermediate of and P. tomentosa and P. davidiana while P. dawidiana originated from Buchum and Suwon appeared to be the intermediate of P. glandulosa and P. davidiana. While P. davidiana had no rooting abillity as expected, P. tomentosa showed about 40% of rooting, which was about one half of the rooting ability of P. alba. P. glandulosa and Buchun & Suwon-originated P. davidiana showed 4~7% of poor rooting. This fact indicated rooting factor from P. alba was flowed into these species. P. tomentosa was reported already as a natural hybrid between P. alba var. Bolleana and P. davidiana in China. We can conclude from above results that P. glandulosa and P. davidiana originated from Buchun and Suwon is supposed to be an individual from hybrid between P. alba and P. davidiana.
