【摘要】 以 1.5年生月季切花品种砂蒙砂、红胜利、金奖章和肯尼迪为材料 ,比较越夏后采用 3种切花标准对月季在切花适期切花总产量的影响。试验结果表明 ,金奖章在 3种切花标准间的切花总产量呈极显著的相关关系 ;砂蒙砂和红胜利二品种呈显著的相关关系 ;肯尼迪无相关关系。月均温与参试的各品种月切花产量的相关性 ,除砂蒙砂 5 0cm的切花标准呈无相关关系外 ,其余均呈显著或极显著的相关关系。更多还原

【Abstract】 In an experiment with four 1.5 year-old rose varieties,3 cutting standards were compared as to their effects on the total output of cut flowers after the summer growing season.The results showed that the three standards were correlated highly significantly with the outpu of “ Gold medal ”,Significantly correlated with cut flower output of “ Red success” ,and non-significantly with that of “ John F. kennedy ”.With the exception of “ Romaso ” with 50 cm as standard length, the output of all varieties was significantly or highly significantly correlated with monthly mean temperature.更多还原
