[Method] Adsorption experiment was carried out in a hermetic container, and the effect of calyx amount, contact time, moisture content of basic tea and temperature on the scenting process was studied. [Result] The optimal moisture and temperature for scenting process was 4% and 10 ℃, respectively. [Conclusion] The scenting process accorded pseudo-first-order kinetic model, and the adsorption dynamic data of total process could better fit pseudo-second-order kinetic model.展开更多

Of them, 10 cross-combinations were included. The results showed that the hybrids were consistently tended to C. azalea on flower bud formation and development, blooming period, leaf trait and plant growth, but flower color, flower form and flower size of the hybrids, in a great degree, were dependent on the traits of another non-C, azalea＇s cross-parent. The hybrids all can bloom from summer to December and even to next spring. The hybrids＇ photographs illustrated in the paper show that their flowers are beautiful with different color, form and size. Also some of genetic laws of C. azalea＇s hybrids were discussed. These fire-new hybrids firstly fill the blank that no camellia flowers can be enjoyed in summer in the world.展开更多
