主 题：Seed biology the ability of plants permit germination
摘 要：Seed biology is an intensive area of study,a reflection of the significance of seeds for several scientific areas.From an evolutionary perspective,the ability of plants to make seeds has conf erred major selective advantages,accounting,in part,for the success of seed plants as the largest and most species-rich group of land plants.The seed habit facilitates fertilization in non-aqueous environments,provides a level of physical and biological protect!on for the female gametophyte and embryo,allows for the massive accumulation of storage proteins,lipids,and/or carbohydrates in the embryo and/or endosperm to serve as a nutrient reserve for the germinating seed and developing seedling,and permits the embryo to remain in a developmentally arrested and metabolically quiescent state until environ mental conditions permit germination to occur(Steeves 1983).
