Brazilian guava (Psidium guineense Swartz.) is a plant species native from Brazil and present in all Brazilian biomes. This species occurs in the Caatinga biome as a wild fruit that has broad utility and can generate income, as well as provide material for breeding. The objective of this work was to study seed germination of guava accessions collected in two municipalities in Bahia. Seeds imbibition curve was studied. Also, seed germination and seedlings initial growth were evaluated for 44 days on different temperatures (15, 20, 25, 30 and 35 °C), fruit maturation, drying, pre-soaking and priming. Seeds imbibition curve was triphasic in which lag-phase begun after 30 hours imbibition and lasted 256 hours. An effect of guava genotype was observed i seeds physiological quality. Temperatures of 20 and 25 °C were ideal for guava seeds germination. Seeds pre-soaking and priming techniques are feasible to reduce germination time and increase seedling performance |

We thank McMichael et al. for commenting on our recent review [1]. They focus on: our misinterpretation of their published data; use of data that is not pre-Conquest; and the extrapolative nature of our review. As they point out, we agree with them about heterogeneous landscape domestication across Amazonia, but we dis- agree with their conclusions about the extent to which forests were altered in western Amazonia and elsewhere [2,3]. As western Amazonia covers approxi- mately 2 000 000 km2, they are making a major statement. We consider their claim to be of an excessively 'extrapolative nature' given their data. |
