Abstract:
【Objective】 To study the seedling emergence and seedling characteristics of three kinds of wild fruit tree seeds planted artificially in the original habitat and explore the seedling regeneration characteristics of wild fruit trees.
【Methods】 After storage in cold stratification, wild apple, wild apricot and wild cherry plum seeds were planted on the flat, shady and sunny slopes of Xinyuan wild fruit forest to observe their emergence and seedling characteristics under natural conditions.
【Results】 The emergence period of wild apricot and wild cherry plum were 19 to 33 days after sowing, and the emergence of wild apple began 13 days after sowing.The seedling rate of wild apricot was 38%-72%, the preservation rate was 93%-100%, and the sunny slope was the best; the seedling rate of wild cherry plum was 22.1%-41.8%, the preservation rate was 46.3%-95%, and the shady slope was the best; the seedling rate of wild apple was 1.5%-6.8%, the shady slope was the best, the preservation rate was 57.4%-83.3%, and the sunny slope was the best.The annual seedlings of wild apricot and wild cherry plum grew the fastest in the flat land, and the annual seedlings of wild apple grew faster in the flat land.The seedlings of three kinds of wild fruit trees were suitable to grow in the flat land.
【Conclusion】 Both wild apricot and wild cherry plum have higher seedling rate and preservation rate after sowing in spring.They are suitable for live propagation in the original habitat, but it is difficult to sow wild apple.The sunny slope is suitable for the survival of wild apricot seedlings, while the shady slope is suitable for the survival of wild cherry plum seedlings.
