The creation of triploid hybrids is an important genetic improvement strategy for the development of new commercial citrus scion varieties. The objective of this work was to quantify the frequency of triploids obtained from natural and controlled crosses of different mandarin varieties under varying environmental conditions in the state of Bahia. The experiments were conducted in the municipalities of Cruz das Almas (Recôncavo Baiano region) and Mucugê (Chapada Diamantina region). The first experiment was based on fruits from open pollinations of the varieties ?Page?, ?Ortanique?, ?Ellendale?, ?Clemenules?, ?Swatow?, ?Piemonte?, ?Fortune?, ?South Africa?, ?Montenegrina?, ?Kincy?, ?Span Americana?, ?Fremont, ?Nova?, ?Dancy? and ?Murcott?, and the second involved fruits from controlled crosses of female parents ?Nova?, ?Fortune? and ?Ortanique? and male parents ?Page?, ?Montenegrina?, ?Swatow?, ?Fremont? and ?Kincy?. The seeds selected were inoculated in test tubes containing approximately 10 mL of Woody Plant Medium (WPM). When the plants reached circa 60 days of age, leaf samples were removed for quantification of the DNA by the flow cytometry technique. In Mucugê, three triploids were identified from open pollinations, ?Clemenules? (1) and ?Ortanique? (2), while in Cruz das Almas, no triploids were obtained. In the controlled crosses, triploids were only obtained in Mucugê: ?Ortanique? × ?Montenegrina? (4), ?Ortanique? × ?Kincy? (1) and ?Ortanique? × ?Swatow? (2). Based on the data, it is suggested that the environmental conditions of Mucugê favored the formation of triploids.

Forest inventory studies in the Amazon indicate a large terrestrial carbon sink. However, field plots may fail to represent forest mortality processes at landscape-scales of tropical forests. Here we characterize the frequency distribution of disturbance events in natural forests from 0.01ha to 2,651ha size throughout Amazonia using a novel combination of forest inventory, airborne lidar and satellite remote sensing data. We find that small-scale mortality events are responsible for aboveground biomass losses of ~1.7PgCy;1 over the entire Amazon region. We also find that intermediate-scale disturbances account for losses of ~0.2PgCy1, and that the largest-scale disturbances as a result of blow-downs only account for losses of ~0.004PgCy1. Simulation of growth and mortality indicates that even when all carbon losses from intermediate and large-scale disturbances are considered, these are outweighed by the net biomass accumulation by tree growth, supporting the inference of an Amazon carbon sink. |
