Performance And Comprehensive Evaluation Of 13 Camellia Oleifera Clones In Shaoguan

In this experiment,13 excellent clones of Xianglin series were planted i n the base of Camellia oleifera forest of Shaoguan Youfeng Eco-garden Developmen t Co.,Ltd.Shaoguan City.Through introducing and planting the excellent clones of Xianglin series,the growth,yield,Fruit Morphological characteristics,seed yield an d oil content of Camellia oleifera were investigated and determined,and the growth performance was compared.The functional components of some clones were detect ed.The subordinate function method,principal component analysis method and analy tic hierarchy process were used to preliminarily select the good clones of Camellia oleifera suitable for Shaoguan cultivation.The results show that:1.Under the same planting and cultivation conditions,the excellent clones of Ca mellia oleifera grew well,and their phenological stages were consistent with the ori ginal production.The germination and leaf development were in mid-March;the flo wering period began in mid-November and lasted about 45 days.However,there are still some differences in growth performance among varieties.2.The height of Xianglin 78 is the highest,followed by Xianglin 27;the crown of Xianglin 27 is the best,followed by Xianglin 350;the ground diameter of Xiang lin 78 is the largest,followed by Xianglin 56.3.Most of the fruits are oval,the transverse diameter of Xianglin 351 is the larg est,the longitudinal diameter of Xianglin 34 is the largest,the seed coat of Xiangli n 35 is the thinnest,and the average seed number of Xianglin 34 is the largest.4.Xianglin 351 had the highest yield per plant,followed by Xianglin 56.The highest fresh seed rate was Xianglin 2,followed by Xianglin 34,and the highest oil content of fresh fruit was Xianglin 350,followed by Xianglin 35.5.In order to better judge and predict the value and benefit of 13 different clon es of Camellia oleifera,the membership function method was used to calculate the score and consider the indexes of tree height,crown width,ground diameter,fruit tr ansverse diameter,longitudinal diameter,pericarp thickness,seed number,fresh seed yield and oil content of fresh fruit.It was found that among the 13 clones,Xiangli n 351 and Xianglin 78 had the greatest potential value and benefit.
