荷花花粉形态学及生活力研究.pdf

文档介绍：河南农业大学硕士学位论文3个品种。%蔗糖+lOOmg/L硼酸+%琼脂。但萌发率过低,在今后的实验中培养基配方有待做进一步研究。。2种染色方法所得的结果均高于培养法,其中亚***蓝染色法明显不能作为荷花花粉生活力的测定方法。培养法的结果能说明花粉的真实萌发率大小,比染色法更为直观更为准确可靠,可作为测定花粉生活力的首选方法。。关键词:荷花;花粉形态;品种分类;生活力2河南农业大学硕士学位论文英文摘要StudyontheMorphologyandViabilityofNelumbonuciferapollenSupervisor::LiChenABSTRACT:,classification,therelationshipbetweenpollenmorphologicalcharacteristicsandplantshape,flowershape,andflowercolor;}tmforpollengerminationandtheeffectsoftimeofpollenstorageonpollenviability,,allpollenapproachessubglobose,hasthreegerminalfurrowsalongthedirectionofpolaraxis,bothendsofthegerminalfurrowarenarrow,butisbroadinthemiddle,pactnesskernelsinthefurrow,:(‘Fenqianye',,thesmallestis‘Jinfengzhanchi’.②,allthevarietieshavedifferentwidthandlengthofgerminalfurrow;Inthegerminalfurrowthereareseveralshapes,suchasobviouslyheave,notobviouslyheaveandinvaginate.③Therearethreeshapesinpolarview,3一labed—rounded,obtusetriangleandsubrotundity.④Therearesignificantdifferencesinexineornamentation,these
