“…Thus, these results substantiate the hypothesis that not all combinations of host and endophyte have similar growth stimulating effects (Hayman, 1980), and this may be interpreted as a kind of functional host specificity or compatibility. Sukhada (1989) also reported G. mosseae to be more beneficial compared to G. fasiculatum in a glass house experiment where papaya (cv.…”

Carica papaya L. is known to exhibit a strong growth response to colonisation by arbuscular mycorrhizal fungi; yet it is generally believed that mycorrhizal growth effects are primarily nutritionally mediated and are inversely related to improved soil fertility, especially available soil P, which affects the fungus symbiotic effectiveness. This study was, therefore, undertaken to evaluate the influence of selective arbuscular mycorrhizal fungi on vegetative growth of Carica papaya L. Studies were carried out in India on mycorrhization of Carica papaya var. Surya seedlings. The experiment comprised of un-inoculated seedlings, seedlings inoculated with Glomus intraradices, seedlings inoculated with Glomus mosseae and seedlings inoculated with mixed inoculum [Glomus intraradices + Glomus mosseae]. Inoculation with arbuscular mycorrhizal fungi significantly (P<0.05) increased all the growth parameters viz., plant height, stem girth, leaf area and root length. Mycorrhizal plants exhibited significant increase in fresh and dry weights of shoot and root systems. A higher root: shoot ratio was also observed in mycorrhizal plants than the control plants. Glomus mosseae was the most effective species of arbuscular mycorrhizal fungi, recording the highest root colonisation and exerting profound influence on growth of papaya.Key Words: Arbuscular mycorrhizal fungi, Glomus mosseae, Glomus intraradices RÉSUMÉ Carica papaya L.est caractérisé par une forte croissance en réponse à la colonisation des champignons mycorrhiziens arbusculaires ; de même il est généralement admis que les effets de la croissance des champignons mycorhiziens jouent un rôle principalement nutritionnel et sont inversement liés à l'amélioration de la fertilité du sol, spécialement à la disponibilité en P dans le sol, ce qui affecte l'efficacité symbiotique du champignon. Cette étude a été entreprise pour évaluer l'influence de la sélectivité des champignons mycorhiziens à arbuscules sur la croissance végétative de Carica papaya L. Des études ont été faites en Inde sur la mycorhization des plantes de Carica papaya var.Syria. L'expérience était composée de plantes non inoculés, de plantes inoculés avec Glomus intraradices et des plantes avec l'inoculum mixte (Glomus intraradices + Glomus mosseae). L'inoculation par des champignons mycorhiziens à arbuscules a montré une augmentation significative (P<0.05) de tous les paramètres de croissance à savoir la hauteur de plantes, le diamètre de la tige, la surface foliaire et la longueur des racines. Les plantes avec mycorhizes ont montré une augmentation significative de la surface foliaire et de la longueur des racines. Egalement, le rapport pousse-racines a été plus élevé chez les plantes avec mycorhizes que celles sans mycorhizes. Glomus mosseae a été l'espèce la plus efficace de mycorhizes à arbuscules, ayant enregistré un grand nombre de racines colonisées et une grande influence sur la croissance du papaya.

“…Populations varied considerably for the same crop at different locations." Hayman (1978) also concluded from a general spore survey of pastures in Otago that there was a large measure of ecological equivalence between Endogonaceae species. General surveys then are only useful for providing qualitative information.…”

“…Cooper and Tinker (1978) used 65 Zn to associate this with direct uptake of Zn by vesicular-arbuscular mycorrhizal (V AM) hyphae and subsequent translocation into the host. Further, it has been shown (Hayman, 1978;Tinker, 1980) that high levels of P can inhibit infection of roots with V AM. Hence, it is possible that increased P levels in the soil may lead to reduced Zn uptake via a reduction of the V AM infection.…”

One-time heavy application of P on certain soils can provide sufficient available P to sustain crop production over a period of several years, but may cause Zn nutritional problem for crops. A field study was conducted to determine tbe effect of applied Zn on wheat (Triticum aestivum L.) grown on residual P plots and identify tbe mechanism of P X Zn interaction. This study was conducted in 1984 in a continuous wheat system on a clayey, mixed, frigid Typic Hyploboroll soil that bad received 0, 80, and 160 kg P ba -• in 1979. Three experiments were carried out using a split plot randomized complete block design with three levels of P as m~in plots and rates of soilapplied Zn-sulfate (0, S, 10, and 20 kg Zn ba-•) or Zn-cbelate (0, 0.5, 1.0, and 2.0 kg Zn ba-1 ) or foliar-applied Zn-cbelate (0 and 0.35 kg Zn ba-•) as subplots. A one-time application of 80 or 160 kg P ba-• increased wheat yield significantly. In the presence of P, application of Zn resulted in significant increase in grain yield and Zn uptake into grain. Applied P increased soil P levels and tissue P concentration, but resulted in a significant decrease of tissue Zn levels. DTP A ( dietbylenetriaminepentaacetic acid )-extractable soil Zn levels in the non-Zn-amended treatment were independent of P application rate. Plant roots in bigb P treatments contained significantly lower levels of vesicular-arbuscular mycorrhizal (V AM) infection than tbe control. Further, a close relationship was observed between Zn levels in tbe aboveground plant parts and V AM infection.AdditioiUll index words: Phosphorus X Zinc interaction, Vesiculararbuscular mycorrbizae, Triticum aestivum L., Zinc-sulfate, Zincchelate.'
