Floral attributes evolve in response to frequent and efficient pollinators, which are potentially important drivers of floral diversification and reproductive isolation. In this context, we asked, how do flowers evolve in a bat-hummingbird pollination system? Hence, we investigated the pollination ecology of two co-flowering Ipomoea taxa (I. marcellia and I. aff. marcellia) pollinated by bats a...

Identifying more cost effective and perceived environmentally friendly techniques for cover crop management can increase their use. This study was conducted to determine the effectiveness and economic viability of using a mechanical rollercrimper as an alternativekillmethod for cover crops. Three cover crops, rye (Secale cereale L.), wheat (Triticum aestivum L.), and black oat (Avena strigosa S...

Abstract Sete-capote tree, a neglected species, has great ecological, cultural and potential economic importance, however, studies for this other native species of the Myrtaceae family are still scarce. The objective study was to elucidate aspects pollen germination viability specie. For experiment, from flowers in pre post anthesis used, which dehydrated chamber containing silica, different pe...

More frequent and more intense heat waves greater drought stress will occur in the future climate environment. Short-term extreme often simultaneously after winter wheat anthesis, which has become major constraint threatening yield. In this study, short-term heat, their combination were applied to plants all restored outdoor normal temperature full watering treatment. The aim of current study w...

The objectives of this experiment were (i) to determine the effect of water supply on the photosynthetic capacity of leaves, bracts, capsule walls, and stalks of cotton at different growth stages and (ii) to determine the contributions of these nonleaf organs to whole plant photosynthesis. Water deficit reduced the total surface area per plant but increased the proportion of nonleaf to total pl...

Despite substantial evidence on the essential roles of cell wall invertase (CWIN) in seed filling, it remains largely unknown how CWIN exerts its regulation early in seed development, a critical stage that sets yield potential. To fill this knowledge gap, we systematically examined the spatial and temporal expression patterns of a major CWIN gene, GhCWIN1, in cotton (Gossypium hirsutum) seeds f...

Cotton fiber developing on cultured ovules is an important experimental tool, even though in vitro grown fibers are shorter than in situ grown fibers. Fiber measurements and microscopy show that early fiber elongation increased when calcium concentration in the culture medium was reduced from the traditional 3 mM to 0.1 mM. Fiber length in 0.1 mM calcium responded negatively to trifuoperazine, ...
