| 摘 要： | 首次对川鄂连蕊茶(Camellia rosthorniana Hand.-Mazz.)的开花生物学特性进行了调查,并研究了光照条件对开花的影响,旨在为品种选育和杂交育种提供依据.结果表明,川鄂连蕊茶花芽分化时间较长,经历了绿蕾期、红蕾期、透色期、松瓣期及开放期5个阶段,持续9～10个月完成.花芽主要分布于当年生小枝的枝顶和叶腋,花数/cm枝条为1.32～1.77朵,单株花期15 ～20 d,单花花期4～5d.光照条件对花芽分化影响差异显著,全光照和郁闭度0.4时花芽分化正常,郁闭度0.7时花芽数量大大减少.综上所述,川鄂连蕊茶花量大、具清香、观赏性好、适合全光照、疏林下种植或室内盆栽观赏,是良好的丰花香花型茶花育种材料.

| Abstract: | The floral biology of Camellia rosthorniana was investigated for the first time,and the influences of different sunlight to flowering were characterized.The results showed that flower bud differentiation lasted for 9 to 10 months,including in green-bud stage,red-bud stage,coloring stage,unfold-petal stage and flowering stage.The large amount flower buds distributed on the top and axils of the annual shoots.The flower number/cm shoot was 1.32 to 1.77,and the flower period/tree was 15 d to 20 days,as well as ... |
