Abstract
Mineral elements are the basis of apple yield and quality, but they exhibit different types of absorption.
Many absorption types have been studied in accordance to their efficacy, and the current study was easy to implement as far as operations and power use.
The study used 8-year-old apple trees (Malus domestica Borkh c.v. Red Fuji). The Se in the Na2SeO3 element was supplied by an automatic drip instrument and a pipe conveyance system, and the dynamic changes in the Se absorption element were studied.
Three concentrations (300 mg.L-1, 600 mg.L-1 and 900 mg.L-1) were applied during the study to the trees, during the floral period, young-fruit period, and pro-mature period.
Roots, shoots, leaves, and fruits in the pro-mature period were gathered and analyzed.
The results showed that the Se contents in different organs were influenced by the supply period, concentration and the reagent.
Se content of the root and leaf were influenced by supplements during the floral period, while the Se content of fruit was influenced significantly by supplements during the young-fruit period, and finally, the Se content of the shoot was changed by supplements during the 30 days before harvest (pro-mature period). Se contents of fruit, leaf, shoot and root were influenced more by supplements in the treatment of 600 mg/L than in the other treatments.
The Se element content could increase 0.96~8.08 times; the sugar content to CK increased 13.27% to approximately 26.60% and 19.61% to approximately 36.79%, respectively.
