Contenido :  Two perennial Trifolium, T. polymorphum Poir. and T. argentinense Speg., are American clovers unique within the genus for being amphicarpic. There is no consensus in the literature regarding the breeding system of the aerial flowers of T. polymorphum, therefore, the breeding system was studied. In 1997 T. polymorphum was collected in Uruguay and evaluated at INIA Tacuarembó. In 2001, 10 field patches were marked and in 2004, 20 plants per patch were characterized with simple sequence repeat markers. Patch J10 showed a particular molecular profile, therefore, 198 open-pollinated progenies freely visited by honeybees were studied. In 2005, at the University of Florida, Gainesville, different hand-pollination treatments were conducted within an accession from Paraguay. Trifolium polymorphum was able to cross-pollinate with all the known pollen donors molecularly marked that surrounded plants from patch J10 (30%), also with some nonmarked native ones from the vicinity (10%) as well as with itself (60%), when allowed to be visited by honeybees. However, when there are no pollinators, the selfing rate is minimal. The proposed classification for the breeding system is an allogamous, self-compatible species that benefits from pollinators to set seed.

Contenido :  ABSTRACT. The in vitro and in vivo control of Phyllosticta citricarpa (citrus black spot, CBS) on citrus fruits was evaluated using 14 essential oils (EOs) extracted from Uruguayan native plants. In vitro, volatile components of Chenopodium ambrosioides completely inhibited fungal growth. The dilution agar test showed that fungus reproduction was completely inhibited by Conyza bonaerensis essential oil (EO). The other 12 EOs tested showed high inhibition after 10?15 d, presenting fungistatic effects. In vivo, assays were performed on fruit of lemon [Citrus limon (L.) Burm] and Valencia orange [Citrus sinensis (L.) Osbeck] in order to evaluate the effects of liquid and volatile EO phases on reproduction. Typical lesions of CBS without reproductive structures were exposed to Ch. ambrosioides and C. bonaerensis EOs for 20 d at 27 C and cycles of 16 h light and 8 h dark. The volatile components of Ch. ambrosioides were able to control 100% of P. citricarpa reproduction in orange and lemon fruit. The growth of other fungi such, as Colletotrichum gloeosporoides and Fusarium sp., was also inhibited. Nevertheless, the liquid phase was not effective to control the pathogen. In another test, carton boxes with 20 fruits, each presenting typical CBS symptoms, but without the presence of reproductive structures, were exposed to 0.01 and 0.05% of Ch. ambrosioides EO (w/v). The fruits were stored at 5 C for 20 d and then kept for 7 d at room temperature. A 40% reduction of reproduction wa... Presentar Todo
