Newer, selective insecticides with few negative impacts on natural enemies and competitor species are needed for effective, sustainable management of the western flower thrips, Frankliniella occidentalis (Pergande). The purpose of this study was to evaluate the impacts on natural enemies and competitor thrips species of insecticides used for control of western flower thrips in fruiting vegetabl...

The goal of this thesis is to design and build a system which automatically classifies an image of a flower for hundreds of flower species. The classification should be done within a reasonable time so that it is usable for a real-time computer vision application. The classification performance of the system is improved if only the flower region (foreground) of the image is considered, and the ...

A pot experiment was carried out to determine the effect of foliage spraying of silicon (Si) on growth and ornamental characteristics of calendula grown under salt stress and greenhouse conditions. A factorial experiment based on completely randomized design was conducted with 3 levels of Si (0, 50 and 100 mg/l) and 3 levels of NaCl (0, 100 and 200 mM) with 4 replications. At flowering stage, S...

gladiolus (gladiolus grandiflorus l.) is one of the most widely cultivated, economically important and common flowering plants worldwide including pakistan. however, its yield of flower is quite low when grown under agro-climatic conditions of multan. a field experiment was conducted at the experimental area, department of horticulture, bahauddin zakariya university, multan (pakistan), during 2...

Nutrition as an environmental factor has a special place in the growth, main and sub branches number of Rosa damascena Mill. and these morphological traits affected yield and flower number of the plant. So, this experiment was conducted in the Research Institute of Forest and Rangelands, Karaj, Iran, to evaluate the effect of macro- and micronutrients on the plant growth. A split plot design wa...

Pickerelweed (Pontederia cordata L.) is a diploid (2n = 2x = 16), erect, emergent, herbaceous aquatic perennial. The showy inflorescences of pickerelweed make this species a prime candidate for inclusion in water gardens and aquascapes. The objective of this experiment was to determine the number of loci, number of alleles, and gene action controlling flower color (blue vs. white) in pickerelwe...

Scarlet rosemallow (Hibiscus coccineus Walter) is a diploid, perennial, erect, and woody shrub. The species is a desirable inclusion in home landscapes because it is a native plant with attractive flowers and unusual foliage. The objective of these experiments was to determine the number of loci, number of alleles, and gene action controlling flower color (red vs. white) in scarlet rosemallow. ...

Nanosilver of nanometer-sized silver (Ag+) particles (2-5 nm diam) are used in various applications as an anti-microbial. Boric acid (H3BO3) is water soluble (pH=7). Boric acid is ethylene synthese inhibitor and reduce ethylene production through reducing the ACC synthase and ACC oxidase delays senescence of flower. In this study of different concentrations of boric acid and nano-silver was eva...

In this study, we aimed to explore the effect of altitude on reproductive ingredient and sex allocation different colors Anemone obtusiloba in populations. The variations three four altitudinal gradients at eastern Qinghai Tibetan Plateau were examined. Our results showed that with increased altitude, gynoecium/flower, androceium/flower gynoecium/individual increased, but androceium/individual,...
