| Abstract: | Having studied the law of inheritance and variation of the quantities of ash, K, N, p, Na and Fe in the fir-heedles and the growth trait from 76 different georaPhic seed origins of china fir,this PaPer make a Principal component analysis of the two significant factors K and growth in the light of the ecological factors of seed origin. Based on the ordering, the 76 origins are divided into six districts and a basis is provided for allocating, transgerring and dividing.the seed origins. |
