9种金花茶组植物在肇庆地区引种的早期评价*

通过从广西引种9个不同品种金花茶,并对其2年期间苗高和地径生长进行对比试验研究。结果表明：防城兴金花茶成活率最高,达100%,珑瑞金花茶苗木成活率最低,仅为74.7%；防城金花茶的苗高生长量最大,为41.6cm,显著大于其他8个品种金花茶(p<0.05)；防城金花茶的地径生长量最大,为1.018cm,凹脉金花茶次之,为0.896cm,两者皆显著大于其他6个品种金花茶(p<0.05)；不同品种金花茶苗木成活率、苗高生长量及地径生长量间存在极显著的正相关关系(p<0.01)。苗木生长综合指标值分析表明,防城金花茶在肇庆地区生长最好,在品种选择方面,可以适当引种防城金花茶。

Study on the growth performance of Camellia chrysantha in Zhaoqing City

9 Camellia chrysantha cultivars were collected from Guangxi province, and a contrast test research of the height and diameter of seedings was conducted during the two years.The results showed that C.chrysantha var.phaeopubisperma achieved the highest survival rate , which reached 100%, and C.longruiensis achieved the lowst survival rate, only 100%; the C.chrysantha var.phaeopubisperma had great height growth rate(41.6 cm), which was significantly greater than other 8 Camellia chrysantha cultivars; the ground diameter growth rate of C.chrysantha var.phaeopubisperma was the largest(1.018 cm), followed by C.impressinervis (0.896 cm), both significantly higher than other 6 Camellia nitidissima cultivars; and there were significant positive correlations among survival rate, height growth rate and diameter growth rate of 9 Camellia chrysantha cultivars. Through the analysis of comprehensive index value of seeding growth, the C.chrysantha var.phaeopubisperma grow best in Zhaoqing and should be promoted in Zhaoqing area.
