Dianthus caryophyllus L. is an important floricultural crop species throughout the world, specially in Eurasia. The present study was conducted to evaluate the nine Dianthus genotypes, including normal and mutagen treated, to assess the magnitude of variability and to pick up the heritable component of variation present in the quantitative traits. The analysis of variance revealed highly signif...

Seed production and patterns of sex allocation were studied in female and hermaphroditic plants in two gynodioecious populations of Geranium sylvaticum (Geraniaceae). Females produced more flower buds and seeds than hermaphrodites in one of the two study populations. The other female traits measured (pistil biomass, seed number per fruit, individual seed mass) did not differ between the gender ...

Soybean exhibits natural variation in flower and seed coat colors via the deposition of various anthocyanin pigments in the respective tissues. Although pigmentation in seeds or flowers has been well dissected at molecular level in several plant species, the genes controlling natural variation in anthocyanin traits in the soybean are not completely understood. To evaluate the genetic correlatio...

Different concentrations of THC stimulate formation of reactive oxygen species in cells that are exposed to smoke from the distal end of the “joint,” indicating that cell damage is caused by toxic gas in the smoke. Lung cancer has emerged as the most common cause of cancer-related death in men and women in the United States (Edmondson, 2008; Swaney, 2002). Marijuana, a product of the Cannabis s...

Echium (Echium plantagineum L.) is an alternative oilseed crop in summer-wet temperate regions that provides floral resources to pollinators. Its seed oil is rich in omega-3 fatty acids, such as stearidonic acid, which is desired highly by the cosmetic industry. Seeds were sown in field plots over three years in western Minnesota in spring (early-sown) or early summer (late-sown), and flower ab...

Rafflesia is said to be vulnerable to extinction because of its biological peculiarities.1 Being unisexual and dioeciously, the male and female flowers need to bloom synchroniously in the same area for effective pollination by carrion flies to succeed. Without new seeds formed to be deposited onto the mature hosts, no one can guarantee that they will be there in the ecosystem forever. It is tru...

producing hybrid lettuce is prevented by flower structure and usually lead to selfing. based on it, this experiment was carried out to evaluate the performance of different physical and chemical emasculation methods for producing lettuce hybrid seed. a numbers of cultivars with dominant and recessive traits were used as male and female parents, respectively. in the first experiment, physical em...

Flowers are reproductive organs and precursors to fruits and seeds. While the basic tenets of the ABCE model of flower development are conserved in angiosperms, different flowering plants exhibit different and sometimes unique characteristics. A distinct feature of strawberry (Fragaria spp.) flowers is the development of several hundreds of individual apocarpous (unfused) carpels. These individ...

Abstract Sunflower plants have many benefits as food, especially for vegetable oil. The development of sunflower cultivation in Indonesia has not been optimal, production. Increasing production requires superior seeds. Therefore, it is necessary to conduct field tests know the growth and yield lowlands before plant assembly. objective this study was determine five adaptive genotypes. research c...

In flowering plants, pollen limitation has been proposed to intensify selection on floral characters important in pollinator attraction, but may also select for traits that increase seed set through autonomous selfing. Here, a factorial design (+/- pollen addition, +/- pollinator removal) was used to investigate how the pollination environment affects selection on floral morphology via female f...
