Advances in Research of Relationship between Morphological Structure and Yield of Castor.

Castor is a cash crop with very wide adaptability in China, and its yield is closely related with its morphological structure. With reference to the research on the relationship between the morphological structure and yield of main cash crops such as rice, wheat and maize, this paper made a review of advances in the research of the relationship between castor variety characteristics, habitat conditions, dry matter distribution, cultivation measures. Finally, it present the research direction, content and route of the relationship between the morphological structure and yield of the castor in the future. [ABSTRACT FROM AUTHOR]
