| Abstract: |
| At Hongling Seed Orchard, Taishan, Guangdong Province, the 12-year-old trees of three clones
from slash pine genetically superior seed orchards “Elite” were as interstocks, and the shoot tips of 17 clones
from three Pinus caribaea varieties were as scions. The effects of different interstock clones and different scion
clones on the survival rate of grafted scions, diameter of live scions, length of living scions, and the amount of
male and female strobili were studied. The results showed that the clone B118 was the interstock clone with the
highest graft affinity, while the clones of B2, B6, C4, C5, H10 and H17 were the scions with a higher graft affinity.
The result of variance analysis showed that different interstock clones had a significant effect on the growth of
diameter and length of the living scions, and scions that grafted to interstock clone A05 had the largest growth.
In terms of flowering traits, among all the living scions, 18.07% of them produced female inflorescences, 6.02%of them produced male inflorescences, and the average numbers of female and male inflorescences were 0.67 and
1.37, respectively. Of the 17 tested scion clones, the living scions of seven clones produced a total of 56 female
and 114 male inflorescences. The effect of promoting flowering on the live scions was different among the three
interstock clones, and the clone B118 had the best effect on promoting flowering. |
