酸梅属于核果类果树,但与杏(Arme-niaca Vulgaris Lam)、李(Prunus Sali-cina lindl)和杏李(Prunuos Simonii Carr)均有显著不同,由此我们对酸梅的亲缘关系及究竟属于何种植物的问题发生了质疑。进而对酸梅的植物学形态特征、生物学特性、果实经济性状和叶片过氧化物同工酶等做了调查、分析研究。认为酸梅是杏与李的自然杂交种(Armeniaca Xpranas)。
Sour plum belongs to the stone fruit tree but differs significantly from Arme-niaca Vulgaris Lam, Prunus Sali-cina lindl and Prunuos Simonii Carr, and therefore, our genetic relationship with Sour plum The question of what kind of plant has been questioned. Furthermore, the morphological characteristics, biological characteristics, fruit economic traits and the peroxidase isoenzymes of P. plum were investigated, analyzed and studied. Sour plum is considered to be a natural hybrid of apricot and plum (Armeniaca Xpranas).
