ABSTRACT Browningia candelaris is a cactus from the Atacama Desert with bat pollination exogenous pollen and pollinators (i.e., xenogamy). In addition, we evaluated natural pollination and the identity of pollinators. The autogamy flowers did not bear fruits, indicating that B. candelaris is unable to produce seeds in the absence of pollinators. Through geitonogamy there was only 20% fruiting, although only in one year, indicating a low capacity for self-pollination mediated by pollinators. About 75% of the flowers fructified by xenogamy indicating that cross pollination is the main reproductive mechanism. However, the xenogamy fruiting was 10% higher than the natural one, and the number of seeds per fruit 34.3% higher, which indicates a low effectiveness of the pollinators. The potential pollinators are the northern hummingbird ( Rhodopis vesper vesper ) and seven species of insects (3 Diptera, 3 Hymenoptera, 1 Lepidopteran). Additional studies on the pollination and reproduction of threatened desert plants seem to be mandatory to propose appropriate conservation strategies.","PeriodicalId":262382,"journal":{"name":"Gayana.

Despite its importance for the development of conservation actions, there are no reports on its propagation by seeds. The objective of the present investigation was to evaluate the germination response, growth, development, and survival of B. chilensis under different pregerminative treatments. To accomplish this objective, 12 treatments were carried out, which included chemical and mechanical scarification, as well as methods of soaking, disinfection and washing of the seeds. Treatments consisted of 5 replicates of 15 seeds were established at 20°C and 12:12 photoperiod. The final percentage and the germination rate were calculated, as well as aerial and root biomass of the seedlings emerged per treatment. 2019). Bajo estas condiciones climáticas, se desarrolla esta especie, su floración ocurre en primavera y sus semillas son dispersadas durante el verano, temporadas que se caracterizan por la ausencia total de precipitaciones. De acuerdo con Baskin & Baskin (2014), cerca de un 90% de las especies arbustivas que crecen bajo condiciones climáticas adversas, presentan algún tipo de dormancia, siendo predominante la dormancia fisiológica (51%), seguida por la dormancia física (38%) y en menor proporción una combinación de ambas (11%). Escaso es el conocimiento sobre el comportamiento de la regeneración de arbustos en el Desierto de Atacama, sin embargo, se reconoce que tanto la germinación, como la mechanical scarification (micropyle cutting of the seeds) favors germination, they generate seedlings with less aerial and root growth, affecting their subsequent survival. On the other hand, with the use of simple treatments such as washing the seeds and soaking them in water with disinfection, it is possible to obtain about 80% germination, favoring the subsequent plant survival and growth. It is expected to improve the production practice of this species, especially focused on its use in restoration programs.","PeriodicalId":262382,"journal":{"name":"Gayana.
