Abstract

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.

Key words: Armeniaca vulgaris, pulpy seeds, no pulp seeds, buried depth, seed germination, seedling growth
