Craterispermum capitatum and C. gabonicum, two new species of Rubiaceae, are described from the Lower Guinea and Congolian Domains. Detailed descriptions and distribution maps are provided for each species, their conservation status is assessed and their taxonomic affinities are discussed. Craterispermum gabonicum is unique within the genus because of the strong dimorphism in brevistylous and l...

Consumption of cut flowers is going to increase day by day in Pakistan. It is related with the rising living standards, education and electronic media that have promoted this business in recent years. The production and consumption of cut flowers has increased over the past decade and this increase is expected to continue. However, local consumption and demand is yet to be satisfied. Gladiolus ...

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...

In hermaphroditic plants, female reproductive success often varies among different positions within an inflorescence. However, few studies have evaluated the relative importance of underlying causes such as pollen limitation, resource limitation or architectural effect, and few have compared male allocation. During a 2-year investigation, we found that female reproductive success of an acropeta...

This study was done to evaluate the effect of different planting arrangements (square, lozenge and rectangular) and various concentrations of potassium sulfate (K2SO4) fertilizer (0, 100, 200 and 300 kg/ha) on yield and essential oils quantitative of Calendula officinalis L., a medicinal and ornamental plant. The experiment was done as a factorial in randomized completely blocks design (R.C.B.D...

The overall aerial architecture of flowering plants depends on a group of meristematic cells in the shoot apex. We demonstrate that the Arabidopsis TERMINAL FLOWER 1 gene has a unified effect on the rate of progression of the shoot apex through different developmental phases. In transgenic Arabidopsis plants which ectopically express TERMINAL FLOWER 1, both the vegetative and reproductive phase...

There has been an explosion of information about flower development recently, largely because of genetic and molecular studies in Arabidopsis thaliana and Antirrhihum majus. A number of homeotic genes have been identified that regulate flower development, and models have been proposed for the specification of meristem and floral organ identities. Molecular cloning of many of these genes has all...

In order to evaluate the effect of plant growth regulators on sex determination and yield, an experiment was conducted by spraying different hormonal combinations on medicinal pumpkin. Experimental treatments were included different concentrations of NAA (25, 75, 100, 125 mg/l), paclobutrazol (50, 100, 200 and 300 mg/l) and combination of growth regulators (NAA 25 mg/l + PBZ 50 mg/l), (NAA 75 m...

Soilless culture (hydroponic) and timely supply of plants’ essential nutrients will increase their quantitative and qualitative performance. To assess the impact of N, K and Mg on yield and fruit quality of strawberry (Fragaria×ananasa cv. Sun Rise) an experiment was performed which included control treatment (no fertilizer application), two levels of urea (100 and 200 mg/L per pot), two levels...
