Enhanced growth of multipurpose Calliandra (Calliandra calothyrsus) using arbuscular mycorrhiza fungi in Uganda.

Sebuliba E, Nyeko P, Majaliwa M, Eilu G, Kizza CL, Ekwamu A - ScientificWorldJournal (2012)

Bottom Line: All Calliandra inoculated seedlings showed improved seedling growth (in terms of height and shoot dry matter weight) compared to the control (P < 0.05) except with the arbuscular mycorrhiza fungi mixture treated Calliandra at 50 spores rate.Glomus sp. and Acaulospora sp. had significant influence on the height of Calliandra, while AMF mixture performed best in terms of shoot dry weight (P < 0.05).This study provides a good scope for commercially utilizing the efficient strains of arbuscular mycorrhiza fungi for beneficial effects in the primary establishment of slow growing seedlings ensuring better survival and improved growth.

ABSTRACT
This study was conducted to compare the effect of selected arbuscular mycorrhiza fungi genera and their application rates for enhanced Calliandra growth in Uganda. The performance of Calliandra under different types and rates of arbuscular mycorrhiza fungi inoculation was assessed in the greenhouse using sterilized Mabira soils. Four dominant genera were isolated from the rhizosphere of sorghum in the laboratory. Calliandra seeds were grown in pots and the seed coating method of application was used at concentrations of 0 spores, 30 spores and 50 spores. Each treatment was replicated three times. All Calliandra inoculated seedlings showed improved seedling growth (in terms of height and shoot dry matter weight) compared to the control (P < 0.05) except with the arbuscular mycorrhiza fungi mixture treated Calliandra at 50 spores rate. Glomus sp. and Acaulospora sp. had significant influence on the height of Calliandra, while AMF mixture performed best in terms of shoot dry weight (P < 0.05). This study provides a good scope for commercially utilizing the efficient strains of arbuscular mycorrhiza fungi for beneficial effects in the primary establishment of slow growing seedlings ensuring better survival and improved growth.

fig1: Temporal change in height of Calliandra.

Mentions: The temporal change in Calliandra height varied significantly within a week, rates of application and genera types (P ≤ 0.05). (Figure 1) 50 spores rates of application and with single AMF isolates gave the best results for Calliandra in comparison with the control and 30 spores' rates of application (P ≤ 0.05). Glomus sp., showed the best results followed by Acaulospora sp., Gigaspora sp., and then Scutellospora sp. Poor results were exhibited by the mixture.The temporal trend in height of Calliandra for the first 18 weeks was natural logarithmic and the regression coefficients ranged from 0.95 to 0.98, the slopes from 1.18 to 1.59, and the intercepts ranged from 2.93 to 3.48.
