果实的发育成熟涉及一系列复杂的生理生化变化,包括叶绿素的降解、类胡萝卜素的合成、淀粉向糖的转化、芳香性化合物的合成、细胞壁溶解和果实软化等。

Researches to the gold-bearing quality of sedimentary and magmatic rocks show that most of these rocks have more gold content than the average of the upper crust. Further evidences are quoted to support the view that fluids exist in shallow crust have the ability resolve some gold. Moreover, in the convergent compression, deep melting of the lower lithosphere can bring some Au and mineralization materials and move up to upper crust. Regional faults, which formed in geosynclinal and diwa periods, controlled the partial distribution of intrusions and gold mineralization belts, i.e.
