Abstract
To determine possible interactions between effects of mycorrhiza and groundcover, micropropagated plants of Mailing 26 (M26) apple (Malus domestica Borkh.) rootstock were subjected to a factorial arrangement of the following 3 treatments: mycorrhizal inoculation, presence or absence of a grass, and low or high fertilizer regime. There were no interactions of grass with inoculation apparent for any measure of apple growth, except for the number of apple root laterals, which was decreased by the grass. A 3-way interaction for apple plant concentrations of P, K, Ca, Mg, Cu, and Zn was due primarily to decreased concentrations of these elements under conditions of high fertility with mycorrhiza in the absence of the grass. The B concentration of inoculated apple plants also was decreased in the absence of the grass.

A commercial inoculum of Glomus intraradices Schenk and Smith, a vesicular–arbuscular mycorrhizal fungus, has been used with the objective of studying its effects on rooting and on subsequent growth of two woody ornamental plants (Juniperus Sabina `Blue Danube' and Cornus sericea `Coloradensis'). This inoculum, called Mycorise™, is produced by Premier Peat Co. (Rivière-du-Loup, Québec, Canada) and it contains one propagule/g of Glomus intraradices. The cuttings's rooting media was mixed in order to contain 0%, 10%, 20%, 40%, or 80% of inoculum. Hardwood cuttings have been inserted in 65-ml cells and put under a mist until good rooting. For both species used, presence of inoculum in rooting media has not given significant effects during the rooting stage of cuttings, but has given some during the following stage of growth in 6-L containers. The growth of young mycorrhized plants of Juniperus was up to 50% greater than the control after the first season of growth. The young plants of Cornus have only showed a tendency to have a higher growth. Moreover, several mineral elements (N, P, Ca, Mn, Zn) were present at higher concentrations on mycorrhized plants. For roots colonization by the fungus and growth results, the inoculum proportion of the rooting media the most appropriate for Juniperus Sabina `Blue Danube', a slow-rooting species, was 40%, and the most appropriate for Cornus sericea `Coloradensis', a quick-rooting species, was 20%.
Two cultivars of carrot were sown in a sandy loam soil over two seasons with and without introduction of commercial inoculum of Glomus intraradices or Glomus etunicatum, which was spread with an experimental sowing machine. VAM fungi effects on the yield and the quality of carrot varied from season to season. In 1997, both of the VAM fungi enhanced the average saleable yield of the two cultivars from 66.21 t/ha to 69.85 t/ha and 80.81 t/ha, respectively, for the treatment without the introduction of VAM fungi, G. etunicatum, and G. intraradices. The slight difference (5.03%) that occured between G. intraradices and the non-inoculated treatment, although not significant, represented 20.38% of the total percentage of rejected carrots. For the last season, the amount of rejected carrots was in the same range for all the treatments (13% to 14%). Nevertheless, both of the cultivars responded differently to mycorrhization. In both of the seasons, mycorrhizal colonization was high in all plots, with an average of 70% in the treatment without inoculation and 75% in those that received G. intraradices or G. etunicatum. In our experimental conditions, reduction of phosphate fertilization to 50% of the recommanded quantity had no influence either on the mycorrhizal colonization or on the yields.
