| Abstract: |
| The effects of fertigation on growth, fruit quality of pineapple cultivar ‘Shenwan’ was investigated. The results suggested that the number of green leaves, length and width of leaf, as well as height of pineapple plant at the point of naturally flower budding were significantly increased by fertigation treatment. The length, circumference and individual weight of pineapple fruits, as well as the yield were notably enhanced by fertigation treatment. Fertigation treatment also significantly increased the mass fractions of TSS, sucrose and titratable acid. Fertigation slightly affected the mass fractions of total sugar and VC of pineapple fruits, as well as declined the mass fraction of reducing sugar. The total mass fraction of ester aroma components of pineapple fruits was slightly increased. While the total mass fraction and number of alkene aroma components were slightly reduced by fertigation. |
