The daylily (Hemerocallis fulva) and nightlily (H. citrina) are typical examples of a butterfly-pollination system and a hawkmoth-pollination system, respectively. H. fulva has diurnal, reddish or orange-colored flowers and is mainly pollinated by diurnal swallowtail butterflies. H. citrina has nocturnal, yellowish flowers with a sweet fragrance and is pollinated by nocturnal hawkmoths. We eval...

Phosphatidylinositol 3-kinase (PI3K) is a key enzyme that phosphorylates phosphatidylinositol at 3'-hydroxyl position of the inositol head group initiating the generation of several phosphorylated phosphatidylinositols, collectively referred to as phosphoinositides. The function of PI3K in plant senescence and ethylene signal transduction process was studied by expression of Solanum lycopersicu...

purpose: the greenhouse cultivation in rural areas is one of the factors that affect the rural economy, this paper analyzes the strengths, weaknesses, opportunities and threats of greenhouse cultivation in rural entrepreneurship development and job creation. methodology: research methods in terms of objective and based on the cross-sectional nature. by referring to the villages and conduct inte...

Handroanthus serratifolius produces flowers during the dry season in the Cerrado biome, and it may be an important food source to some bird species. For Psittacidae species, like Forpus xanthopterygius, flowers are important in their diet. This study intended to characterize the behavior of F.xanthopterygius and evaluate the damage to the flowering and in the reproduction of H. serratifolius. F...

The number of plants pollinated by ants is surprisingly low given the abundance of ants and the fact that they are common visitors of angiosperms. Generally ants are considered as nectar robbers that do not provide pollination service. We studied the pollination system of the endangered dry grassland forb Euphorbia seguieriana and found two ant species to be the most frequent visitors of its fl...

Foraging pollinators could visit hundreds of flowers in succession on mass-flowering plants, yet they often visit only a small number--potentially saving the plant from much self-pollination among its own flowers (geitonogamy). This study tests the hypothesis that bumble-bee (Bombus impatiens) residence on a particular plant depends on an assessment of that plant's reward value relative to the ...

The relatively brief postharvest life of most cut flowers and potted flowering plants can be extended by a range of technologies. Studies have shown that vase life is negatively correlated with respiration after harvest, so prompt cooling to the lowest safe storage temperature is a key to long-distance transport of these perishable crops. Forced air cooling is the method of choice for cut flowe...

In recent years, herbaceous flowering potted plants have widely been used to be planted in garden area but these species might be also used as interior plants. Post production performance of flowering potted plants under interior conditions has become a research area of great interest. The aim of this work was to evaluate whether Salvia splendens may have a potential use as short-term colour so...
