[Development and structure defense strategies on the fruit of Chaenomeles speciosa].

OBJECTIVE
To study the development rule and structure defense strategies on the fruit of Chaenomeles speciosa.


METHODS
Anatomical and histochemical methods were used to investigate the structure and localization of tannin of the fruit of Chaenomeles speciosa.


RESULTS
The development of the fruit of Chaenomeles speciosa were divided into two periods: cells reproduced rapidly from fluorescence to 40 - 50 days after fluorescence, and cells augmented after this. The pericarp and seeds were protected by beceptacle which was formed by cuticle, epidermis, taniniferous cells layer, parenchyma cells which contained tannin and stone cells zones. Tannin was distributed in parenchyma cells of beceptacle mostly and in pericarp barely.


CONCLUSION
The development and structure of fruit of were related with its defense strategies.
