Effects of Coccus viridis on the Fruit of Coffea arabica
In order to clarify the impact of Coccus viridis on Coffea arabica fruits,13 phenotypic traits of coffee fruits were measured to analyze the effects of Coccus viridis on the coffee fruits.The results showed that the damage of Coccus viridis significantly reduced berry weight,berry longitudinal diameter,berry transverse diameter,seed longitudinal diameter,seed shape index,peel weight and seed number,and significantly improved the fruit hardness.There was a correlation between most fruit traits in coffee,and the damage caused by Coccus viridis had an impact on the correlation between fruit traits.There were 4 pairs of common correlations between fruits with and without Coccus viridis damage,with 4 and 6 pairs of differentially related traits,respectively.Principal component analysis showed that 13 phenotypic traits could be summarized into 2 principal components,namely seed quantity factor and hardness factor.Finally,two key indicators,namely the number of seeds and hardness,were determined as the key indicators for the impact of Coccus viridis on Coffea arabica fruits.
