| 摘 要： | The growth characterlstlcs, different physlological parameters, photosynthetic activity （^14CO2 fixation）, and the translocatlon rate of photoassimllates In different taro （Colocasia esculenta L. Schott） genotypes was studled In order to determlne the posslble use of these parameters as selectlon crlterla for dlfferent wldely used genotypes of taro （Delta No. 9, 15, 20, 21, and balady）. The results obtalned suggest that Delta No. 21 shows the most slgnlflcant increase In all parameters tested compared wlth the control （balady）, followed by Delta No. 9, 15, and 20, respectively. The results show a positive correlation between photosynthetlc actlvlty, translocatlon efflclency, and total yield. The selected clone Delta No. 21 Is recommended for cultlvatlon In the delta reglon of Egypt.

| Abstract: | The growth characteristics, different physiological parameters, photosynthetic activity (14CO2 fixation), and the translocation rate of photoassimilates in different taro (Colocasia esculenta L. Schott) genotypes was studied in order to determine the possible use of these parameters as selection criteria for different widely used genotypes of taro (Delta No. 9, 15, 20, 21, and balady). The results obtained suggest that Delta No. 21 shows the most significant increase in all parameters tested compared with the control (balady),followed by Delta No. 9, 15, and 20, respectively. The results show a positive correlation between photosynthetic activity, translocation efficiency, and total yield. The selected clone Delta No. 21 is recommended for cultivation in the delta region of Egypt. |
