Variation in floral sex allocation in Polygonatum odoratum (Liliaceae).
BACKGROUND AND AIMS It is well known that resource allocation to male and female functions can be highly variable in hermaphroditic plants. The purpose of this study was to investigate variations in sexual investment at different levels (flower, plant and population) in Polygonatum odoratum, a plant with sequentially opening flowers. METHODS Pollen and ovule production in base, middle and top...
متن کاملFloral Sex Allocation in Sequentially Blooming Plants.
In plants whose flowers develop in a sequence, different flowers may exhibit temporal variation in pollen donation and receipt such that the fitness contributions through male and female functions can vary among flowers. Dichogamy, or directional pollinator movements within inflorescences, can create situations where flowers in different stages in the sequence may differ in the numbers of flowe...
متن کاملPolygonatum odoratum lectin promotes BECN1 expression and induces autophagy in malignant melanoma by regulation of miR1290
Autophagy is not only a survival response to growth-factor or nutrient deprivation but also an important mechanism for tumor-cell suicide, including melanoma. Polygonatum odoratum lectin (POL) displays apoptosis- and autophagy-inducing effects in many human tumors. POL also inhibits the growth of melanoma cells, but its role and molecular mechanism in malignant melanoma remain unclear. In this ...
متن کاملVariation in floral sex allocation and reproductive success in sequentially flowering inflorescence of Corydalis remota var. lineariloba (Fumariaceae).
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...
متن کاملOptimization and Composition of Volatile Oil from Polygonatum odoratum (Mill Druce) using Supercritical Fluid Extraction
Purpose: To determine the effects of temperature, pressure and extraction time on oil yield obtained from Polygonatum odoratum as well as the optimum processing conditions for supercritical carbon dioxide (CO2) extraction. Methods: Supercritical CO2 extraction technology was adopted in this experiment to study the process of extraction of volatile oil from Polygonatum odoratum while gas chromat...
