Meloidogyne enterolobii (syn. M. mayaguensis) has been reported to cause severe damage in commercial guava orchards and other plants in Central and South American countries. Considering the risk of introduction and dissemination of this pest in the European region, M. enterolobii was placed on the EPPO A2 list in 2010. The use of non-host fruit species is a recommended strategy to manage root-knot nematodes in infested guava orchards. This study screened 89 plant genotypes from 25 fruit plants of economic importance, plus two susceptible controls (guava and tomato) for its host status to M. enterolobii. Three to eight months after inoculation, nematode reproduction factor (RF) was used to characterize host suitability of fruit crops to this nematode. Ten banana genotypes, six Barbados cherries, one fig, two grape rootstocks and six melons were rated as good hosts for this nematode. Sixteen fruit plants behaved either as non-hosts or poor hosts to M. enterolobii, including assaí, atemoya, avocado, cashew nut, citrus, coconut, grape, jabuticaba, mango, mulberry, papaya, passion fruit, sapodilla, soursop, starfruit and strawberry. For the future, field experiments in areas infested by this nematode are essential to confirm the greenhouse results. These non-host fruit species can replace in the future eradicated guava trees in fields severely infested by this nematode and become an economic option for growers where M. enterolobii is considered a serious problem. |

Experiments under laboratory conditions were carried out with the objective of studying hydrogen uptake in the Azolla-Anabaena system. Tritium was used as tracer and plants were incubated under different atmospheric composition: a) Air + 3H2; b) Air + 3H2 + CO; c) Air -h 3 H2 -I- CO, d) Argon -1- 3 H2 + C02 -I- CO and in presence and absence of light, to study hydrogen uptake via hydrogenase and nitrogenase activity. Azolla-Anabaena showed greater hydrogen uptake under argon atmosphere than under air. Carbon monoxide decrease hydrogen uptake as well as nitrogenase activity. Under dark conditions, nitrogenase activity was smaller under argon than air atmosphere. Carbon monoxide decreased hydrogen uptake. H2 -uptake was not affected by light, as it occurs under dark conditions. There are evidences of recycling of the hydrogen evolved through nitrogenase. |
