“…Effective species include: G. mosseae, G. claroideum and G. fasciculatum. A survey of 67 soil and papaya samples the north of Espírito Santo and Bahia States, Brazil, demonstrated a range of colonization ranging from 6% to 83% (Trindade et al, 2006). Colonization rates and spore density were positively correlated with soil organic matter and coarse sand fractions and negatively correlated with fine sand.…”

Papaya (Carica papaya L.) is a principal horticultural crop of tropical and subtropical regions. Knowledge of how papaya responds to environmental factors provides a scientific basis for the development of management strategies to optimize fruit yield and quality. A better understanding of genotypic responses to specific environmental factors will contribute to efficient agricultural zoning and papaya breeding programs. The objective of this review is to present current research knowledge related to the effect of environmental factors and their interaction with the photosynthetic process and whole-plant physiology. This review demonstrates that environmental factors such as light, wind, soil chemical and physical characteristics, temperature, soil water, relative humidity, and biotic factors such as mycorrhizal fungi and genotype profoundly affect the productivity and physiology of papaya. An understanding of the environmental factors and their interaction with physiological processes is extremely important for economically sustainable production in the nursery or in the field. With improved, science-based management, growers will optimize photosynthetic carbon assimilation and increase papaya fruit productivity and quality. Key words: Carica papaya, environmental factors, photosynthesis, water relations, water-use efficiency Ecofisiologia do mamoeiro: uma revisão: O mamoeiro (Carica papaya L.) é uma das principais culturas das regiões tropicais e subtropicais. O conhecimento das respostas dessa cultura aos fatores do ambiente pode fornecer bases científicas para traçarem-se estratégias de manejo que possam otimizar a produção e a qualidade dos frutos. Um melhor entendimento das respostas dos genótipos aos fatores específicos do ambiente poderá contribuir para um eficiente zoneamento agrícola e para futuros programas de melhoramento da espécie. Objetivou-se apresentar o estado-da-arte do conhecimento relacionado aos efeitos e à interação dos fatores ambientes sobre o processo fotossintético e a fisiologia da planta inteira. Nesta revisão, demonstra-se que os fatores do ambiente, como luz, vento, característica físicas e químicas do solo, temperatura, água no solo, umidade relativa, além de fatores bióticos, como fungos micorrízicos e o genótipo, podem afetar intensamente a produtividade e a fisiologia do mamoeiro. Uma compreensão da ação dos fatores do ambiente e suas interações com o processo fisiológico dessa espécie são de grande importância para a sustentabilidade econômica da produção do mamoeiro, em condições de viveiro e de campo. A partir de um manejo da cultura baseado em resultados científicos, será possível otimizar a assimilação fotossintética do carbono e elevar a qualidade e produção de frutos do mamoeiro.

“…Carica papaya is pollinated by Lepidoptera, but wind-assisted pollination has also been reported (Hernández and Acosta 1992). Carica papaya blooms and fruits all year, and cultivars have been reported as mycotrophic (Trindade et al 2006).…”

The different resource demands on male and female plants of dioecious species can lead to secondary sexual dimorphisms. Male and female plants might also interact differently with antagonists and mutualists. We used a repeated measures natural experiment in five subpopulations to investigate secondary sexual dimorphism in Carica papaya including interactions with arbuscular mycorrhizal fungi. Male and female plants did not differ in size or growth rate, but male plants flowered earlier than female plants. We observed different patterns of root colonization by arbuscular mycorrhizal fungi in male and female plants of C. papaya. These differences between the sexes preceded the flowering of most female plants. Female plants were sensitive to changes in soil fertility and adjusted the extent of their root colonization by arbuscular mycorrhizal fungi accordingly. Overall, the different resource demands on male and female plants seem to modulate the interactions of C. papaya with arbuscular mycorrhizal fungi.

“…This is in agreement with earlier studies of Zhang et al [31,32] on peach inoculated with another arbuscular mycorrhizal fungus, Funneliformis mosseae. The negative response of root colonization to soil R treatment is due to toxic substances accumulated in the rhizosphere that further restrict spore germination and the hyphal growth of AMF [33]. In this study, inoculation with A. scrobiculata showed a favorable improvement in the total plant biomass, irrespective of soil NR or R conditions.…”

Effects of Mycorrhizae on Physiological Responses and Relevant Gene Expression of Peach Affected by Replant Disease

A potted experiment was carried out to evaluate the effect of an arbuscular mycorrhizal fungus (AMF), Acaulospora scrobiculata, on peach seedlings grown in non-replant (NR) and replant (R) soils, to establish whether AMF inoculation alleviated soil replant disease through changes in physiological levels and relevant gene expression. After 15 weeks of mycorrhization, root mycorrhizal colonization was heavily inhibited by R treatment versus NR treatment. AMF plants under NR and R soil conditions displayed significantly higher total plant biomass than non-AMF plants. AMF inoculation significantly increased root sucrose and fructose concentrations and root catalase, peroxidase, polyphenol oxidase, and phenylalanine ammonialyase activities under R conditions. Likewise, salicylic acid, jasmonic acid, chitinase, total soluble phenol, and lignin concentrations in roots were significantly higher in AMF than in non-AMF seedlings grown in R soil. Over-expression of PpCHI, PpLOX1, PpLOX5, PpAOC3, PpAOC4, and PpOPR2 in roots was observed in AMF-inoculated seedlings, as compared to that of non-AMF-inoculated seedlings grown in R soils. Thus, mycorrhizal fungal inoculation conferred a greater tolerance to peach plants in R soil by stimulating antioxidant enzyme activities, disease-resistance substance levels, and the expression of relevant genes.
