3年测定不同雄性育性桃花器官营养元素 ,结果表明 :随着花粉母细胞发育期进展 ,不同育性花器官中元素含量变化为 :Ca呈从高 -低下降趋势 ;而Zn呈上升趋势 ;Cu、B从低 -高 -稍高 -低 ;N、P、Mg、Mn、K呈低 -渐高 -高 -稍低趋势。成熟可育雄蕊中有低的Ca、Mg、Cu、B等含量和高的N、P、Mn等含量。Ca、B可能与花粉管向化性物质有关 ;钾与促进蛋白质和核酸形成 ,保持原生质的水合程度有关 ;N与可育花粉中游离脯氨酸 ,水解酶类等有关 ;P与核酸含量有关 ;Mn与花粉能量代谢有关 The results showed that with the development of pollen mother cells, the content of elements in different fertile floral organs changed from high to low and from Zn to Zn; Cu, B from low - high - slightly high - low; N, P, Mg, Mn, K was low - high - high - slightly lower trend. Mature fertile stamens have low Ca, Mg, Cu, B and other content and high N, P, Mn and other content. Ca and B may be related to the pollen tube to the chemical substances; potassium and to promote the formation of proteins and nucleic acids to maintain the degree of protoplast hydration related; N fertile pollen free proline, hydrolytic enzymes, etc .; P and nucleic acid content Mn is related to energy metabolism of pollen
