Suppose that p = (p1,p2, . . . ,pN ) and q = (q1,q2, . . . ,qN ) are two configurations in Ed, which are centers of balls B(pi, ri) and B(qi, ri) of radius ri, for i = 1, . . . , N . In [9] it was conjectured that if the pairwise distances between ball centers p are contracted in going to the centers q, then the volume of the union of the balls does not increase. For d = 2 this was proved in [1...

Background: The aim of this study was to clarify the relationship between the sexual reproduction and the resource allocation in a natural Polygonatum humile population grown in a temperate mixed forest gap. For this aim, the plant size, the node which flower was formed, the fruiting rate, and the dry weight of each organ were monitored from June 2014 to August 2015. Results: Firstly, in 3–13-l...

Abstract This work aimed to investigate the interaction between salt stress and application of silicon dioxide-nanoparticles. In this study, gerbera plants grown in soilless culture were supplied with nutrient solutions different NaCl concentrations (0, 5, 10, 20 30 mM) combination SiO 2 -NPs spray 25 50 mg · L −1 ). Exposure salinity increased sodium concentration but decreased potassium calci...

This study was carried out to investigate the effect of hydropriming on seed germination and seedling growth of five different flower seed species (Antirrhinum, Dahlia, Impatiens, Salvia and Zinnia). Hydropriming (20oC, 24 h), surface dried or dried back afterwards, was found to increase germination percentage, seedling emergence and fresh and dry weight. In all species, the maximum advantage i...

Abstract Organic fertilizers can be used in cauliflower cultivation as liquid organic fertilizer from Paitan. Paitan is a weed with matter and nutrients that increase soil plant fertility. The response of growth production was examined different doses paitan fertilizer. randomized block design this research five groups treatments then tested applying the Duncan New Multiple Range Test at signif...

There is growing concern that current pollinator decline will affect the reproduction of plant species, potentially driving a decline in plant population densities. We experimentally tested whether a reduction in flower visitation caused a reduction in fertilization rate in several species, and whether any reduction in fecundity of species depends on their degree of reproductive dependence on p...

The experiment was carried out to investigate the effect of different concentrations of salicylic acid (SA), malic acid ( MA), citric acid (CA) and sucrose (Suc) on keeping quality and vase life of Chrysanthemum cut flowers. In this study three levels of malic acid (0, 100 and 150 mg l ) and salicylic acid (0, 1.5 and 3 mM) and two levels of sucrose (0 and 3% w/v) and of citric acid (0 and 150 ...

Capparis decidua is xerophytic shrub, commonly known as Kair. The ethanolic extracts (50%) of different parts of Capparis decidua i.e. bark, fruit and flower (500 mg/kg b. wt.) were used to evaluate their glucose lowering potential. Diabetes (type 2) was induced in rats of either sex, aged 48 ± 2 hrs, were injected with Streptozotocin in citrate buffer (pH 4.5) at a dose of 90mg / kg body weigh...
