The use of tomato seedlings grown in trays provides an improvement in the productive system of tomato cultivation, however, there are still doubts regarding the volume of cells trays, mainly with the cost:benefit of seedlings ...
Pollination of Anemopaegma album (Bignoniaceae) with focus on floral nectar as the mediator of interactions with mutualistic and antagonistic bees
(2015)
We focused our study on the pollination of Anemopaegma album, a Bignoniaceae species from and on the features of primary attractive, the nectar, which mediate the interaction with mutualists and antagonists bees. We ...
Vegetation changes and sequential flowering after rain in the southern Atacama Desert
(Academic Press, 1999)
We describe the changes in plant cover, species richness, and flowering after rainfall over an entire growing season (September 1989-January 1990) in a southern Atacama Desert site in Chile. One month after the rain, ...
Fire does not change sprouting nor flowering, but affects fruiting phenology in a Neotropical savanna community
(2021-10-01)
In fire-prone ecosystems, such as savannas, fire has been a common event for thousands of years. In these biomes, phenology is a functional trait characterizing the responses of plant communities to fire. In this study, ...
Reproductive phenology of useful Seasonally Dry Tropical Forest trees: Guiding patterns for seed collection and plant propagation in nurseries
(2017-06-01)
The propagation in nurseries of native plant species potentially useful for agroforestry, silvopastoral and restoration programs is hindered by an inadequate supply of high quality seed. Limitations in our knowledge on the ...
