Abstract: The biological characteristics of floral of some magnoliaceous species which relate with the crossing practice are examined and the hybridization techniques are summarized.It is found that the maturity of gynoecium is earlier than androecium,the stigmas are receptive before a flower opens,so the best period for pollination is 1~2 d away from opening.It is better to collect pollen in half-opening period when the anthers begin opening and the pollen quality is also the best.For the pollen storage,the suitable condition is drying(using desiccants)and low temperature(2~5℃ in refrigerator)which can keep pollen for about one month with the 50% vitality.
