dc.description.abstract | The contribution of
Trichoderma asperellum
T34 to the plant uptake of phosphorus (P) from sparingly phytoavailable forms
such as insoluble calcium (Ca) phosphates and phytates was studied. Two experiments with cucumber (
Cucumis sativus
L.) on
siliceous sand were performed involving two factors, namely: (i) P source, viz. KH
2
PO
4
, phytate (Ins6P), and phos
-
phate rock (PR), and (ii) inoculation with T34. Liquid pure cultures of T34 were also used. T34 increased the total
content in P of cucumber roots irrespective of the particular P form and enhanced total P uptake by plants with
P supplied as Ins6P or PR. The increased phytase activity observed with T34 contributes to explain its favourable
influence on the uptake of P supplied as Ins6P. Solubilization of Ca phosphates from PR was favoured by the slightly
acidifying effect and the increased organic anion concentration promoted by the fungus in the plant growth media.
It can be concluded that T34 can improve P nutrition in plants grown on media containing phytates or insoluble Ca
phosphates as dominant P forms. | es |
