The coccinellid predator Coleomegilla maculata (DeGeer) is found throughout the central and eastern United States and is a potential biological control agent for interiorscapes. Currently, the systemic insecticide imidacloprid is widely used in interiorscape and landscape integrated pest management. Effects of imidacloprid on the Þtness and behavior of C. maculata were examined by conÞning grou...

Fifteen pentacyclic triterpene diols and triols, consisting of: six taraxastanes, faradiol (1), heliantriol B0 (2), heliantriol C (3), 22a-methoxyfaradiol (4), arnidiol (5), and faradiol a-epoxide (6); five oleananes, maniladiol (7), erythrodiol (8), longispinogenin (9), coflodiol (10), and heliantriol A1 (11); two ursanes, brein (12) and uvaol (13); and two lupanes, calenduladiol (14) and heli...

The antioxidant function of edible flowers have attracted increasing interest. However, information is lacking on the impact of edible flowers on oxidative injury including hypoxia-re-oxygenation and hyperlipidemia. The antioxidant activities of aqueous extracts from 12 Chinese edible flowers were assessed in four different antioxidant models, including total antioxidant capacity (TAC), oxygen ...

Although a number of plant carotenoid cleavage dioxygenase (CCD) genes have been functionally characterized in different plant species, little is known about the biochemical role and enzymatic activities of members of the subclass 4 (CCD4). To gain insight into their biological function, CCD4 genes were isolated from apple (Malus x domestica, MdCCD4), chrysanthemum (Chrysanthemum x morifolium, ...

Abstract Flower shape is a key trait of ornamental and commercial importance in breeding programs for chrysanthemum ( Chrysanthemum morifolium Ramat.). Understanding the genetic basis phenotypic variation seen inflorescence-related traits will contribute to improvement development new varieties. In this study, we investigated determinants inflorescence using an F 1 segregating population derive...

Chrysanthemum morifolium propagation through stem cutting produces weak plants that show delayed anthesis above 20 °C and a reduced flower diameter. Therefore, in this study chrysanthemum plantlets were produced somatic embryogenic from calli to exploit the somaclonal variation for their improvement. Various explants variety Dante yellow cultured on Linsmaier Skoog (LS) medium with various conc...

In this paper, two polarimetric segmentation techniques for polarimetric SAR images are compared. They are both based on the maximum generalised likelihood approach and on a Wishart distribution model. The first technique, named POLSEGANN, is based on a global likelihood approach and on the simulated annealing maximization technique, while the second one (POL MUM) is based on a Maximum Likeliho...

Airborne dermatitis belongs to a heterogeneous group of dermatoses of various etiopathology and clinical characteristics. This disease is characterized by acute or chronic inflammation of the uncovered skin exposed to irritants or allergens. Initially skin lesions are transient. The paper presents a description of chrysanthemum growers diagnosed with air-borne dermatitis from chrysanthemum. Eti...

Mutation rates vary by orders of magnitude across biological systems, being higher for simpler genomes. The simplest known genomes correspond to viroids, subviral plant replicons constituted by circular non-coding RNAs of few hundred bases. Previous work has revealed an extremely high mutation rate for chrysanthemum chlorotic mottle viroid, a chloroplast-replicating viroid. However, whether thi...
