不同修剪时间对油茶果实性状的影响

Effect of Different Pruning Time on the Characters of Camellia Oil

分析了不同修剪时间对油茶单果重、果实大小和果实籽粒数的影响。结果表明:不同的修剪时间,油茶果实性状各指标均以冬季修剪时最大,分别为单果重22.8g,果径33.8mm,果高35.8mm,单果籽粒数5.6粒,500g鲜粒数300粒,分别比对照高18.9%、13%、4.5%、25%和6.7%;修剪可以显著影响油茶单果重、果径及单果籽粒数,对果高、500g鲜粒数的影响不显著。

The present study investigated the influence of different pruning time on the weight of single fruit, fruit size and the number of fruit grain of Camellia oleifear. The results showed that all properties indexes of Camellia oleifear achieved the maximum value under winter pruning. The highest weight of single fruit, fruit width, fruit high, single fruit grain number and fresh grain number of per 500g were 22.8g, 33.8mm, 35.8mm, 5.6 grain and 300 grains and were much higher 18.9%, 13%, 4.5%, 25% and 6.7% than the uncontrolled sample, respectively. On the other hand, pruning could significantly influence the weight of single fruit, fruit width and single fruit grain number, while had no significant affection on the fruit high and fresh grain number of per 500g of Camellia oleifear.
