Flowering patterns are defined by the timing, duration, and frequency of flowering. Plants, particularly in the tropics, vary enormously with respect to these main variables of flowering. We used data from 302 tree species in a wet tropical forest to test a series of predictions regarding timing, duration, and frequency of flowering and examined the effect of each variable on the other two. Bec...

Gentiana leucomelaena manifests dramatic flower color polymorphism, with both blue- and white-flowered individuals (pollinated by flies and bees) both within a population and on an individual plant. Previous studies of this species have shown that pollinator preference and flower temperature change as a function of flower color throughout the flowering season. However, few if any studies have e...

The flowering of grasses is a process critical to plant population dynamics and genetics, herbivore performance, and human health. To better understand the climate factors governing grass flowering, we analyzed the patterns of culm production over 25 years for three perennial tallgrass prairie species at Konza Prairie in Kansas, USA. The three species (Andropogon gerardii, Sorghastrum nutans, a...

there is limited literature on how to engage the rural women in agriculture and improve their contributions to household food security and income. this study aimed to contribute to literature on women engagement in agriculture through vegetable production using good agricultural practices. the empirical data used were drawn from technology demonstrations and experimentation, learning fields, an...

Effects of NPK 15:15:15 compound fertilizer and planting season on flowering and sex expression of pumpkin were analyzed at the Teaching and Research Farm, Obafemi Awolowo University, Ile-Ife, Nigeria in year 2010. Results deciphered that day to 50% flowering, number of male and female flowers responded to season than fertilizer rates. Late season planting reached 50% flowering 5 days earlier t...

Knowledge of the floral cycle and the spatial distribution and abundance of flowering plants is important for bee health studies to understand the relationship between landscape and bee hive productivity and honey flow. The key objective of this study was to show how AISA Eagle hyperspectral data and random forest (RF) can be optimally utilized to produce flowering and spatially explicit land u...

A birch pollen emission model is described and its main features are discussed. The development of the model is based on a double-threshold temperature sum model that describes the propagation of the flowering season and naturally links to the thermal time models to predict the onset and duration of flowering. For the flowering season, the emission model considers ambient humidity and precipita...
