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 ...

BACKGROUND The Tehuacán Valley is one of the areas of Mesoamerica with the oldest history of plant management. Homegardens are among the most ancient management systems that currently provide economic benefits to people and are reservoirs of native biodiversity. Previous studies estimated that 30% of the plant richness of homegardens of the region are native plant species from wild populations....

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 ...

Carnivorous plants belong to endangered species. Due to agricultural development, natural populations of these plants are diminishing. The herbal and ornamental value of these species has also led to their over-collection. The Drosera genus is a natural source of pharmacologically important compounds (e.g. naphthoquinones, flavonoids, anthocyanins, phenolic compounds) used as substrates in the ...

The eastern lubber grasshopper, Romalea microptera (Palisot de Beauvois) (Orthoptera: Romaleidae)[also known as R. guttata (Houttuyn)], is known to be polyphagous, but little else is known about its diet. Choice and no-choice tests were conducted to determine plant preference. In choice tests, 104 different plants were presented and relative preference was determined using ‘Romaine’ lettuce (La...

lehmannia valentiana is one of the most important pests of ornamental plants, vegetables and other agricultural crops, which causes noticable damages. in a food experiment four kinds of food for 24 and 72 hours were offered. the preferences of food were amaranthus tricolor, cineraria grandiflora, pelargonium peltatum, rosa damascena and l. valentiana. the l. valentiaiia is active the whole year...
