In self-compatible, hermaphroditic plants, display size-the number of flowers open on a plant at one time-is believed to be influenced by trade-offs between increasing geitonogamous selfing and decreasing per-flower pollen export as display size increases. Experimental results presented here indicate that selection through male function favors smaller display sizes in Ipomoea purpurea. In small...

Human perception of plant leaf and flower colour can influence species management. Colour and colour contrast may influence the detectability of invasive or rare species during surveys. Quantitative, repeatable measures of plant colour are required for comparison across studies and generalisation across species. We present a standard method for measuring plant leaf and flower colour traits usin...

genetic diversity is essential in the implementation of breeding programs. in order to determine genetic diversity, factor analysis and heritability of yield and some morphological traits, 20 strawberry cultivars were studied at the agricultural station of kurdistan research center using a randomized complete block design with three replications. morphological characteristics such as number of ...

Rhubarb, a famous traditional Chinese medicine, shows wide range of physiological activities and pharmacological benefits. Rhubarb anthraquinones are perceived as the pharmacologically active compounds understanding metabolism them is crucial to assure safety effectiveness clinical application. In this study, pharmacokinetics, tissue distribution excretion five rhubarb (aloe-emodin, rhein, emod...

According to traditional Chinese medicine theory (1), pancreatitis is a " splenic precordial pain " or " hypochondriac pain, " caused by excessive drinking , gluttony, or gloomy mood, or secondary to biliary tract ascariasis, gallstones, and other diseases. To date, no specific drugs have been able to cure acute pancreatitis, and management is typically conservative. Traditional Chinese and Wes...

in this research, the effect of foliar spraying times and different levels of farmax® nano fertilizer on morphological characteristic and dry and fresh flower yield, essential oil and chamazulene percentage of chamomile (matricaria recutita l.) cv. bodegold was studied. the experiment was factorial in the bacic of randomized complete blocked design (rcbd) with eight treatment and four replicati...

Flower color variation among plant populations might reflect adaptation to local conditions such as the interacting animal community. In the northwest Iberian Peninsula, flower color of Gentiana lutea varies longitudinally among populations, ranging from orange to yellow. We explored whether flower color is locally adapted and the role of pollinators and seed predators as agents of selection by...

Transcriptional regulations are involved in many aspects of plant development and are mainly achieved through the actions of transcription factors (TF). To investigate the mechanisms of plant development, we carried out genetic screens for mutants with abnormal shoot development. Taking an activation tagging approach, we isolated a gain-of-function mutant abs2-1D (abnormal shoot 2-1D). abs2-1D ...

Amongst Chelsea Flower Show's champion blooms last month, a range of diseased specimens helped flag up key plant research goals.

The development of a novel non-sulfided catalyst with high activity for the hydrotreatment processing of plant oils, is of high interest as a way to improve the efficient production of renewable diesel. To attempt to develop such a catalyst, we first synthesized a high activity flower-like Ni-PTA catalyst used in the hydrotreatment processes of plant oils. The obtained catalyst was characterize...
