遮阴对番石榴果实生长和品质的影响
The Effects of Shading on the Growth and Quality of Guava
摘要
Abstract
To investigate the effects of different types of shading on the growth and quality of guava,Pearl guava was used as the experimental object,and three treatments were set up:no shading,30%shading,and 50%shading.The chlorophyll content of guava leaves,fruit growth,and quality were measured.The results revealed that the SPAD values of chlorophyll in guava leaves under 30%and 50%shading increased by 24.41%and 26.75%,respectively;30%shading significantly reduced the rate of sunburn and the percentage of diseased fruits,with the percentage of good fruits reaching 94.32%.After 50%shading,the longitudinal and transverse diameters,average single fruit weight,soluble solids,VC,total sugar,and reducing sugar content of guava fruits were significantly lower than those without shading,and after 30%shading treatment,and the total acid content was also significantly increased.However,there was no significant difference between the 30%shading and no shading treatment except for the content of reducing sugars.In summary,compared with no shading and 50%shading,30%shading is more conducive to ensuring the yield and quality of guava.关键词
