ABSTRACT
<p><b>OBJECTIVE</b>To study the characteristics of pollen viability and stigma receptivity of C. deserticola and provide theory basis for seed production and breeding of C. deserticola.</p><p><b>METHOD</b>Different physiological measurement methods were applied to evaluate pollen viability and stigma receptivity. The results of different methods were compared with the seed setting percentage of the cross-pollination in the field test and pollen germination percentage by fluoroscope observation methods. The changes of pollen vitality and stigma receptivity in different conditions were tested using proper methods.</p><p><b>RESULT</b>The optimum methods on pollen viability and stigma receptivity detection were MTT-test and Benzidine-Hydrogen Peroxide method respectively. Results showed that the mean pollen viability and stigma receptivity were both the highest in inchoate anthesis with pollen germination percentage up to 95%, and can maintain viable for 4-5 d, but at the lower temperature of 4 degrees C, the pollen can be stored up to 10 days.</p><p><b>CONCLUSION</b>The physiological characteristics of pollen and stigma of C. deserticola displayed good ecological adaptation, which are much more adaptive to the large area of cultivation condition.</p>
