A Morphological Analysis on the Sexual Organ(sporocarps)of Hybrid progenies between A.microphylla and A.mexicana

In 1992,both mega and micro sporocarps with normal reproductivity have been achieved from interspecific,hybrids crossed by A.micropylla and A.mexicana,The morphology of sexual organgs of parent material as well as their F1 hybrids was analy:ed by optical and scanning elec-tron microscopes,The exoperine and float surface of megasporocary and the glochidial appearance includinig the sepla number in glochdium of microsporocarp massules were compared among them.The result provided an useful basis for the classification of Azolla species and the identification of hybrid progenies.
