The High Arctic winter is expected to be altered through ongoing and future climate change. Winter precipitation and snow depth are projected to increase and melt out dates change accordingly. Also, snow cover and depth will play an important role in protecting plant canopy from increasingly more frequent extreme winter warming events. Flower production of many Arctic plants is dependent on mel...

Given their small size and high metabolism, nectar bats need to be able to quickly locate flowers during foraging bouts. Chiropterophilous plants depend on these bats for their reproduction, thus they also benefit if their flowers can be easily located, and we would expect that floral traits such as odor and shape have evolved to maximize detection by bats. However, relatively little is known a...

Kew Gardens in London opened last month the first gallery in the world to open all year round dedicated to botanical illustrations. The gallery will showcase art from Kew’s unique historic collections as well as Shirley Sherwood’s contemporary collection of botanical art. The two collections, which complement each other, will allow Kew to show to the public many of its largely unseen works and ...

New cDNA sequences for chalcone synthase (CHS), a key enzyme in the flavonoid biosynthesis, were obtained from the Japanese and common morning glories; they are more closely related to other CHS sequences than the six previously described CHS genes from the same plants. The newly isolated CHS-D gene is abundantly expressed in the pigmented flower buds, while its expression is drastically reduce...

several plant growth regulators are used to improve the quality of cut flower in bulb plants, but their effectiveness depends on genotype and plant growth conditions such as nutrition status. a pot experiment was conducted under farm condition to study benzyl adenine (ba) and potassium nitrate interaction on floret diameter, stem diameter, flower height, flower number per bulb, fresh and dry we...
