Cultivation Experiment of Elaeocarpus Braceanus Container Seedlings in Yunnan and Tibet
To address the production challenges of long cultivation cycles and high seedling costs for Elaeocarpus braceanus seedlings,four experimental groups were set up:room temperature seed storage and germination(A),cold treatment seed storage and germination(B),room temperature seed storage with kernel extraction and germination(C),and cold treatment seed storage with kernel extraction and germination(D).The effects of kernel extraction and cold treatment germination on germination rate,seedling transplant survival rate,and seedling growth were investigated.The results showed that cold treatment at 3 ℃ for 30 days significantly improved the germination rate in the same year of sowing,with the cold-treated seed kernel germination rate(82.3％)being 27.4 times that of the room temperature seed kernel(3.0％),and the cold-treated seed kernel germination rate(91.3％)was 37.3 percentage points higher than that of the room temperature seed kernel(54.0％);kernel sowing also significantly increased the germination rate in the same year of sowing,with the room temperature seed kernel germination rate(54.0％)being 18 times that of the room temperature seed kernel(3.0％),and the cold-treated seed kernel germination rate(91.3％)was 9 percentage points higher than that of the cold-treated seed kernel(82.3％);there were no significant differences in seedling transplant survival rate and growth among the treatments,all of which met the specifications required for production or afforestation seedlings and rootstocks.The research results provide scientific basis and technical support for the industrial cultivation of Elaeocarpus braceanus seedlings.
