Abstract

Abstract:

To clarify the branching characteristics of ‘Changlin’ varieties in Camellia oleifera, six years old trees from eight varieties were selected to investigate the branching number, length of shoot and new leaf ratio of different parts of canopy. The results showed that dramatic difference was found among different parts of canopy in branching number, length of shoot and new leaf ratio. And the branching number, length of shoot and new leaf ratio in the outer canopy were significantly higher than that in inner canopy. The lowest branching number in inner canopy was found in variety ‘Changlin 18’ and ‘Changlin 23’, while the highest branching number was found in variety ‘Changlin 3’ and ‘Changlin 53’. The variety ‘Changlin 21’ had the longest spring shoot, while the average length of spring shoot was the lowest in variety ‘Changlin 3’. In addition, the highest new leaf ratio in inner canopy was found in variety ‘Changlin 53’ and ‘Changlin 166’, while the variety ‘Changlin 4’ and ‘Changlin 23’ showed the lowest new leaf ratio in inner canopy. The 8 tested ‘Changlin’ varieties could be divided into 3 types depending on their branching characteristics, which were ‘Changlin 18’ and ‘Changlin 21’, ‘Changlin 53’ and ‘Changlin 166’, and ‘Changlin 3’, ‘Changlin 4’, ‘Changlin 23’ and ‘Changlin 40’, respectively.

Key words: Camellia oleifera, ‘Changlin’ varieties, spring shoot, branching number, new leaf ratio
