Abstracts |
The effect of different P-sources on growth, leaf
chemical composition, and fruit soluble solids and acid content
was evaluated in mycorrhizal Victoria grapevine variety grafted
onto the rootstocks 3309C or 110R. Mycorrhizal and non
mycorrhizal plants were grown in 20 L pots containing 20 kg soil
supplemented with different P-forms: (Calcium bis-dihydrogen
- 92 -
phosphate, tri-calcium phosphate, aluminium phosphate, iron 011)
phosphate) with different solubility, equivalent to 90 kg
P.ha(-1). The percent of mycorrhizal root colonization was
higher in insoluble P-form treatments compared to control or to
soluble P-form treatment (CaDP), ranging from 66 to 84% in
treatments receiving insoluble P, from 36.67 to 38.33% in
control and from 25.33 to 27.33% in soluble P-form treatments.
The roots of 110R rootstock showed higher colonization rate
compared to the 3309C. Mycorrhizal colonization increased both
the pruning weight and number of nodes of the vines, up to 9 and
1.9 times respectively, according to the rootstock-P form
combination. Mycorrhizal vines showed increased leaf
concentrations in N, P, K, Ca. Fruit total soluble solids of
mycorrhizal vines were about 30% lower compared with those of
the non mycorrhizal vines. Both factors, mycorrhizal
colonization and P-forms had no significant effect in fruit
titratable acidity
