Effects of Different Fruit Loads on Leaf and Fruit Traits of Camellia Oleifera Cenruan 2
摘要
Abstract
In order to better guide Camellia oleifera production,taking 10-year-old C.oleifera Cenruan 2 as re-search objects,leaf and fruit traits of plants with different fruit loads[T1(<1.0 kg/m2),T2(1.0-1.4 kg/m2),T3(>1.4-1.8 kg/m2)and T4(>1.8 kg/m2)]were determined and effects of changes in fruit loads on plant leaves and fruits were analyzed.Results showed that leaf morphological indexes and nutrient contents generally showed de-creasing trends and fruit oil rates generally showed increasing trends with increase of fruit load.Fruit load had significant or extremely significant negative correlations with leaf length,leaf width,leaf area,contents of total nitrogen,total phosphorus,total potassium and chlorophyll,and had no significant correlations with fruit eco-nomic traits(except for fruit shape index).It had significant or extremely significant positive correlations with oil rate of seed kernel,oil rate of dry seed,oil rate of fresh seed and oil rate of fresh fruit.Fruit expansion of C.oleifera Cenruan 2 was not affected by increase of fruit load in range of 0.85-2.12 kg/m2,but accumulation of nutrients in leaves might be inhibited.Fruit economic traits and oil rates performed better at fruit load of T3.关键词
