Reproductive tendency of clonal plants in various habitats

Abstract

Abstract: This paper summed up the reproductive strategies and the ecological adaptability of clonal plants in six different habitats such as forest understory,steppe,desert,farmlands and water area,and discussed the trade-off relations or relative importance of sexual vs.asexual reproduction which regularly change with water status,light and temperature.Such regularity was clarified as:the harsher the environment is,the more asexual reproduction would contribute to the regeneration and survival of the populations.In addition,we compared the ecological and functional properties of sexual vs.asexual reproduction modes,reviewed recent researches on the trade-off relations between the two reproductive modes,and mentioned some factors influencing such tradeoff relations.Finally,we made a prospect about future research of reproductive strategy of clonal plants especially in terms of approaches.

Key words: Oryza sativa, Enzyme activity, Grain-filling, Photooxidation
