Logistic regression analysis of relationship between severity of fruit splitting and mineral element content of Prunus salicina Lindl

To investigate the relationship between mineral elements and the severity of fruit splitting of Prunus salicina Lindl., 15 orchards with different degrees of fruit splitting were selected and divided into mild, moderate and severe splitting wards. The correlations of the severity of fruit splitting...

Description
Summary:To investigate the relationship between mineral elements and the severity of fruit splitting of Prunus salicina Lindl., 15 orchards with different degrees of fruit splitting were selected and divided into mild, moderate and severe splitting wards. The correlations of the severity of fruit splitting with soil physical and chemical properties and mineral element content in leaves were analyzed by logistic regression analysis. The results revealed that when the content of soil organic matters was high, the bulk density was low and the total porosity was high, or when the calcium (Ca) content in soil and leaves was high, the fruit splitting of Prunus salicina Lindl. was milder. It is worthy of noting that the higher the manganese (Mn) content in soil and leaves, the severer the fruit splitting of Prunus salicina Lindl. Whether its pathogenic mechanism works by inhibiting Ca absorption or triggering Mn toxicity requires further research.
