Changes of phenotypic characters and oil content of Camellia oleifera during fruit development.

Taking Hanzhong common Camellia oleifera Hanyou 3, Hanyou 4, Hanyou 5, Hanyou 18 and Hanyou 30 as the research objects, Hanyou 7, Hanyou 10, Changlin 4 and Changlin 59 were selected as references, and the phenotypic characters and oil content of nine varieties Camellia oleifera during the fruit development period from July to October in 2018 and 2019 were observed and measured. The results showed that from July to August, it was an important period for the increase of fruit size. It was the fastest increase time in the weight of Camellia oleifera fruit from July to September. In the process of fruit ripening, the thickness of pericarp gradually became thinner. The fruit shape was divided into olive shape, ovate, globose and orange shape, in which the number of ovate fruit and globose fruit was the most. The weight of single seed was different among the samples. The weight of...
