tuberose (polianthes tuberosa l.) is one of the most important cut flowers in tropical and subtropical areas. this flower has forth order in cut flower and second order in bulbous plants production in iran. plant spacing and nitrogen necessity are the most important factors for tuberose quality and quantity. in this study, field experiment carried out as factorial design in randomized complete ...

The present study investigates the antioxidant, anticancer, anticholinesterase, anti-genotoxic activities and phenolic contents of flower, fruit and seed methanol extracts of Hypericum retusum AUCHER. The amounts of protocatechuic acid, catechin, caffeic acid and syringic acid in methanol extracts were determined by HPLC. Total phenolic content of H. retusum seed extract was found more than fru...

Self-incompatibility has been studied by using controlled pollination, pollen tube growth and PCR methods in the Iranian almond ‘Mamaei.’. Pollen tube growth and fruit set following self and cross-pollination treatments were evaluated. The percentage of initial and final fruit set was determined for each treatment at 30 and 60 days after controlled pollination. Pollen germination and pollen ...

Plant spacing and nitrogen are the most important factors for increasing tuberose quality and quantity. In this study, field experiment carried out as factorial Randomized Completely Block Design (RCBD) in 3 replications. Different levels of nitrogen (0, 50, 100, 150, 200, 250 kg/ha) of ammonium nitrate was used. Second factor was different plant spaces (10, 15, 20 and 25 cm). Results showed th...

Andromonoecy is hypothesized to evolve as a mechanism enabling plants to independently allocate resources to female and male function. If staminate flower production is a mechanism to regulate allocation to female function (i.e., fruit production), then large-fruited species should be more strongly andromonoecious than smaller-fruited taxa because more resources are required to mature large fru...

conclusions according to antioxidant activity outcomes, the amount of ic50s of aqueous extracts of flower and stem and also butylated hydroxyl toluene (bht) as standard were 232.34, 63.25 and 45.59 ppm respectively. ultimately, it was highlighted that antioxidant activity of aqueous extract of flower was weaker than stem. results sixty one compounds were identified in the essential oil of the f...

Several species of flower thrips, including the Florida flower thrips {Frankliniella bispinosa (Morgan)}, Western flower thrips {F. occidentalis (Pergande)}, Eastern flower thrips {F. tritici (Fitch)}, and Scritothrips ruthveni Shull, have recently become known as pests of cultivated blueberries (Spiers et al. 2004). The three Franklinella species are pests of both rabbiteye and southern highbu...

The growth and development of Helicoverpa armigera was observed in the laboratory by feeding them on different foods viz; leaf, flower and fruit of lady finger, cotton, pigeon pea and chick pea. Based on the food ingested, food digested and food excreted as well as on weight and size of the larvae and the duration of larval period, the fruit of chick pea was found to be the most suitable food f...

Understanding the determinants of tropical forest tree richness and spatial distribution is a central goal of forest ecology; however, the role of herbivorous mammals has received little attention. Here we explore the potential for red colobus monkeys (Procolobus rufomitratus) to influence the abundance of Markhamia lutea trees in a tropical forest by feeding extensively on the tree’s flowers, ...
