Abstract :
The effects of wheat inoculation with Glomus intraradices and fertilization with rock
phosphate were studied in investigated pot soils in phytotron at University of Western Australia. The
experimental treatments were arranged in four randomized complete blocks in a factorial experiment.
Two wheat genotype consisting of Brookton and Krichauff; three different rock phosphates, i.e.
MonoCalcium phosphate (CaHPO4)(Control), Hydroxy apatite [Ca10(PO4)6(OH)2] and North Carolina
rock phosphate; and two fungal treatments, i.e. inoculation and uninoculation with G. intraradices
were studied in this experiment. Wheat fresh weight, dry weight, leaf area, stem height, P and Zn
concentration in shoot and root, soil phosphorus content and root colonization percentage evaluated
in physiological maturity stage. The greatest positive interaction effect on growth and phosphorus
contents of wheat plants was obtained in those treatments which received MonoCalcium phosphate
and were inoculated with G. intraradices. Plants grown with Hydroxy apatite had higher growth and P
concentration than those grown with North Carolina rock phosphate. All of measured parameters,
except leaf area, were higher in Krichauf. Inoculation treatments significantly increased all of
measured characteristics in compared with uninoculation treatments. The present finding showed that
mycorrhizal colonization increased tissue P concentrations in different experimental treatments.
