Comparison of Economic Traits During Fruit Ripening of Olive Fruits Grown in Different Cultivation Sites in Longnan
To study the effects of different planting sites in Longnan City on the fruit growth of different olive oil varieties,4 olive oil varieties planted in the Wudu District of Longnan City,including Laixing,Ezhi 8,Miracle,and Pixiaoli,were examined.Their fruit phenotypic traits during various growth stages,fertilization and fruit set,seed growth,stone hardening of the endocarp,mesocarp formation,and fruit maturity,were compared to analyze changes in water content and oil content during fruit growth.This aimed to identify suitable cultivation areas for different oil olive varieties and support the optimization of oil olive planting resource allocation in the Longnan area.The results showed that the appearance of different varieties of olive fruits planted in Jinping Village and Daoqi Village in the Wudu District of Longnan City was elongated,and the Laixing olives planted in Jinping Village had both higher fresh weight per hundred fruits and oil content than those in Daoqi Village,with the fresh weight per hundred fruits and oil content during the mesocarp formation stage being 34.82%and 72.53%higher than those in Daoqi Village,respectively.Ezhi 8 olives planted in Daoqi Village had lower fresh weight per hundred fruits than those in Jinping Village during the early growth period,whereas the number was reversed during the later growth period,with the fresh weight per hundred fruits in Daoqi Village during the mesocarp formation 26.00%higher than that in Jinping Village.The oil content of Ezhi 8 olives planted in Jinping Village was higher than those planted in Daoqi Village with the oil content 84.48%higher than Daoqi Village during the maturity stage.Miracle olives planted in Jinping Village had both higher fresh weight per hundred fruits and oil content than those in Daoqi Village,with the fresh weight per hundred fruits during the hardening of the endocarp stage being 36.00%higher than Daoqi Village,and the oil content during the fruit maturity stage being 53.71%higher than Daoqi Village.Pixiaoli olives planted in Jinping Village had a higher oil content than those in Daoqi Village,with the oil content during the mesocarp formation stage being 76.13%higher than Daoqi Village.Thus,it is evident that the Laixing and Miracle olives planted in Jinping Village were superior to those in Daoqi Village,with the fruits being more suited for oil production.Ezhi 8 and Pixiaoli,being suitable for both oil and table use,could be planted in both Jinping Village and Daoqi Village which would yield great growth as well.
