Terpenoid contents of traditionally used ethnobotanically important plants (n=25) were determined. Ethanol extracts seeds, fruits, pods, branches, bark, rhizome and whole plant parts prepared preliminary phytochemical investigation was carried out. Total terpenoid in ethanol determined through qualitative quantitative analytical assay by Salkowski test. Results analysis revealed that the...

We investigated the ability of RNA interference (RNAi) directed against two co-orthologs of AGAMOUS (AG) from Malus domestica (domestic apple, MdAG) to reduce the risks of invasiveness and provide genetic containment of transgenes, while also promoting the attractiveness of flowers for ornamental usage. Suppression of two MdAG-like genes, MdMADS15 and MdMADS22, led to the production of trees wi...

Although domestication of the grapevine (Vitis vinifera L.) has been extensively documented, the history of genotype selection and evolution of vineyard management remain relatively neglected fields of study. The find of 454 waterlogged grapevine pips from a well-dated Etrusco-Roman site in the Chianti district (Tuscany, Central Italy) is an extraordinary chance to gain insights into the progre...

A study of two cultivars of ‘egusi’ melon [Citrullus lanatus (Thunb.) Matsun and Nakai] known as bara and serewe, was undertaken at the Teaching and Research Farm of the University of Agriculture Makurdi in 2010. The aim was to study the effects of variable developmental stages and position of fruits on the mother plant on seed quality. Bulk crop was raised and fruits that developed from date t...

The flowers or inflorescences of certain primitive seed plants are able to regulate their temperature during blooming by modulating the rate of heat production to remain much warmer than the surroundings. A large drop in ambient temperature causes a smaller drop in flower temperature which causes an increase in the rate of heat production by futile involvement of the cytochrome and alternative ...

The flavonoids are a group of low molecular weight, naturally occurring, plant products widely distributed in the vegetarian kingdom and all are based on the parent compound flavone (2phenylchromone or 2-phenylbenzopyrone). They occur in fruits, vegetables, nuts, seeds leaves, flowers and barks. The average daily western diet contains about 1 g of mixed flavonoids, an amount that might be suffi...

BACKGROUND Flowering synchrony and floral sex ratio have the potential to influence the mating opportunities and reproductive success through female function. Here, we examine the variances in synchronous display of female and male function, ratio of male to female flowers per day and subsequently reproductive output in small populations of two monoecious plants, Sagittaria trifolia and Sagitta...

Chemical composition of the essential oils extracted from the leaves, stems, flowers and seeds of  Heracleum rechingeri Manden. were analyzed by GC and GC/MS. Twenty-four components were characterized for the leaf oil with Octyl acetate(47.2%), Octanol(15.2%) and E-caryophyllen (5.7%) as the main constituents. 25 compounds were identified in the stem oil with Elemicin (65.3%), Octyl acetate (13...

Information from Literature Much has been published about pollination, pollinators, pollinizers, fertilization and fruit set in text books and periodicals. The definitions are not difficult. Pollination is the movement of pollen among compatible flowering plants (cross-pollination) or from anthers to stigmas on the same plant or different plants of the same clone (self-pollination). Many plants...

Abstract Garlic mustard [ Alliaria petiolata (M. Bieb.) Cavara & Grande] is an invasive Brassicaceae species native to Europe. As obligate biennials, A. rosettes require a sufficient length of cold during the winter flower following spring. such, mild temperatures could limit species’ potential western and southern distribution in North America. The goal this research was characterize verna...
