摘要:

为探明新疆野杏(Armeniaca vulgaris)种子萌发与幼苗生长对果肉和埋土深度的响应,以期为新疆野杏的天然更新与实生苗培育提供理论参考。通过2种果皮结构(有果肉和无果肉)的种子在不同埋土深度(地表至18.0 cm的14个梯度)对新疆野杏种子萌发和幼苗生长进行研究,旨在揭示果皮结构和埋土深度对新疆野杏种子萌发与成苗能力的影响。结果表明:果肉和埋土深度显著影响野杏种子的萌发、幼苗生长与质量(P<0.05)。埋土深度<3.0 cm不利于成苗,埋土深度>6.0 cm时,萌发能力与幼苗生长量随埋土深度的增加而降低,3.0~6.0 cm为适宜埋土深度。无果肉种子萌发优于有果肉种子,萌发率、萌发指数、成苗率、活力指数分别增长了37.18%、3.88%、37.18%、26.59%,幼苗高、基径、叶片数量、根冠比、幼苗质量指数分别增长了36.99%、7.48%、68.69%、20.61%、14.29%,其萌发能力与幼苗生长量显著高于有果肉种子(P<0.05)。有无果肉种子的萌发和幼苗生长指标与埋土深度呈显著负相关(P<0.05)。研究结果表明,无果肉处理对新疆野杏种子萌发和幼苗生长具有一定的促进作用,在埋土深度为3.0~6.0 cm时,新疆野杏种子萌发整齐性高。

Abstract:

In order to explore the response of seed germination and seedling growth of Armeniaca vulgaris to pulp and buried depth, and provide theoretical reference for natural regeneration and seedling cultivation of A. vulgaris, the seed germination and seedling growth of A. vulgaris were studied by seeds of two kinds of pericarp structure(pulp and no pulp) at different buried depths(14 gradients from surface to 18.0 cm). The results showed that pulp and buried depth significantly affected seed germination, seedling growth and quality(P<0.05). The buried depth <3.0 cm was not conducive to seedling, and the germination ability and seedling growth decreased with the increase of buried depth when buried depth >6.0 cm, 3.0-6.0 cm was the optimal buried depth, and the germination of seeds with no pulp was better than that of seeds with pulp, the germination rate, germination index, seedling rate and vigor index increased by 37.18 %, 3.88 %, 37.18 % and 26.59% respectively, seedling height, basal diameter, leaf number, root-shoot ratio and seedling quality index increased by 36.99%, 7.48%, 68.69%, 20.61% and 14.29%, respectively. The germination ability and seedling growth were significantly higher than those of pulpy seeds(P<0.05). The seed germination and seedling growth indexes of pulp and no pulp seeds were significantly negatively correlated with buried depth(P<0.05). The results showed that the no pulp seed had a certain promotion effect on seed germination and seedling growth of A. vulgaris, and the germination of seeds of A. vulgaris was optimal at the buried depth of 3.0-6.0 cm.
