the genus fritillaria comprises of 165 taxa of medicinal, ornamental and horticultural importance. evolutionary relationships in this genus is an interesting research area, attracting many researchers. in this study, phylogenetic relationships among 18 native to endemic species in iran belonging to four subgenera petilium, theresia, rhinopetalum and fritillaria, are assessed using chloroplast t...

plants are the most common bioindicatorsused in air quality biomonitoring studies because they are immobile and they have more sensitive to the most prevalent air pollutants than humans and animals. to identify the concentrations and sources of heavy metals in ornamental plants of isfahan landscape, samples of leaves and soil around pinuseldarica and nerium oleander were collected at different ...

Tree peony (Paeonia suffruticosa Andrews) is a perennial woody shrub bearing large and colorful flowers. However, the flowering period is short and relatively uniform, which to an important extent hinders the cultivation and exploitation of ornamental peonies. In this study, the segregation of an F₁ population derived from P. ostti 'Feng Dan' (an early-flowering cultivar) × P. suffruticosa 'Xin...

Perennial grasses are promising candidates for bioenergy crops, but species that can escape cultivation and establish self-sustaining naturalized populations (feral) may have the potential to become invasive. Fertile Miscanthus × giganteus, known as "PowerCane," is a new potential biofuel crop. Its parent species are ornamental, non-native Miscanthus species that establish feral populations and...

Tree peony (Paeonia suffruticosa Andrews) is a very famous traditional ornamental plant in China. P. delavayi is a species endemic to Southwest China that has aroused great interest from researchers as a precious genetic resource for flower color breeding. However, the current understanding of the molecular mechanisms of flower pigmentation in this plant is limited, hindering the genetic engine...

Induced mutagenesis is well recognized as one of the most important technology for the development of new varieties through genetic manipulations. Mutation techniques, using physical and chemical mutagens, have successfully produced quite a large number of new promising varieties in different ornamental plants. This technique has been most successful in ornamental plants due to some additional ...

Information is highly scarce about the possible effect of a late spring frost on physiological response buds in ornamental trees. In this study, temperature Changchun at Northeast China was recorded to identify characteristics false by detecting extraordinary warming and sudden freeze early April 2017. Buds six local tree species were investigated for their dynamics biomass, non-structural carb...

PREMISE OF THE STUDY Exotic diseases are threatening many North American tree species, and management of diseases requires understanding the biology of the host as well as the pathogen. Ulmus americana is a widespread dominant tree of eastern North America that has been widely planted as an ornamental and shade tree. Populations of the species have suffered heavy mortality from Dutch elm diseas...

The Early Modern period in Europe was a time of citrus-mania, when the cultivation and classification of citrus resulting in true collections appeared all over Europe. While scholarship has mainly concentrated on the Italian legacy, I argue that one should change perspective and concentrate on the Iberian (IP) legacy. The particularity of orange groves in the IP derives precisely from their pro...
