“…Pertya triloba is an understory species that must survive under conditions of limited resources. The threshold size for flowering has been shown to depend on resource allocation to the reproductive organs and the number of propagules (Kachi & Hirose 1985; Hori et al 1987; Iwasa & Cohen 1989).…”

Pertya triloba (Asteraceae) is a perennial herb growing in the understory of deciduous broad‐leaved forests in central Japan. Its capitulum consists of a single floret that differs from those of most other Asteraceae species. A bagging experiment clearly showed that breeding of P. triloba required cross‐pollination. By using female fertility as a measure of pollination success, the effect of an attractive floral display on the threshold plant size for flowering in P. triloba was surveyed. The number of florets per plant in a P. triloba population was artificially adjusted between one and 30. In both control plants and experimental plants with adjusted floret number, the seed set increased with an increase in the number of florets per plant and became constant (60%) when the floret number per plant was more than 10. Thus, the number of florets per plant has an important role in attracting pollinators, and more than 10 florets per plant must be the effective floral display size. In the P. triloba population, 98.5% of the flowering plants had 10 or more flowers. The effective floral display size might be determined through the mutual relationship between plants and pollinators. The number of florets per plant increased with an increase in the plant leaf area. Therefore, the threshold plant size for flowering might be determined by the productivity needed to support an attractive floral display.

Observations of the flowering phenology and measurements of the heights of understory herbaceous plants were made in a cool temperate deciduous forest, where light availability is relatively low and fluctuates markedly through the year, and it is too cold for many plants to grow in winter. Ninety-one species were recorded between April and October. The number of flowering species as a function of date showed a bimodal distribution. The plants flowering in spring and those flowering from late summer to early autumn each accounted for about 40% of the number of species. The plants that flowered in spring were smaller than those that flowered later in the season. The springflowering plants would produce flower buds in the previous growing season, as the time from the appearance of the aerial part to flowering was transient. Some species completed their main life history events during the spring as spring ephemerals. The small sizes in these species may result from bud formation in the previous 8eason and/or the short period of growth. The plants that flowered in late summer and early autumn, by contrast, were large. These plants should have relatively long periods of vegetative growth and flower at the end of the growing season using matter produced in that year. A long vegetative growth period would tend to make plants firm and/or large. It was suggested that flowering phenology was separated into two periods by the climatic and environmental constraints of a cool temperate deciduous forest.Plant flowering phenology has a close relationship with life history strategy and is affected by various factors including climatic conditions, habitat environments, and interactions with other organisms (Rathcke and Lacey 1985). In a given biome, the flowering phenology pattern of a plant community through the year shows trends that reflect the constraints of climatic factors and habitat conditions; many herbaceous plants flower immediately after the wet season in South India (Sivaraj and Krishnamurthy 1989), dry conditions caused by low river levels trigger flowering in East African riverine forests (Kinnaird 1992), flowering phenology is constrained by a cool and short growing season in the Arctic (Thbhallsd6ttir 1998), and so on.The light regime in a habitat is considered to affect the production of matter in plants. On a forest floor, light availability is relatively low. Especially in a cool temperate deciduous forest, light availability fluctuates markedly through the year and many plants are unable to grow in winter. Uemura (1994) tested leaf phenology patterns in a forest understory and suggested that leaf habits have relationships with the light regime of habitats and climatic conditions. Because reproduction is limited by matter production, the flowering pattern of the understory herb community may be also related to climatic and environmental conditions. However, only a few studies have focussed on the flowering phenology of the understory herbaceous community in a temperate deciduous forest in terms of habitat condi...

Over the past two decades, there has been a tremendous increase in the use of indigenous herbal medicinal plants in modern medicine; however, there is still a significant lack of research data in this field. This incomprehensive information base shades thedevelopment of a comprehensive research agenda especially in the context of developing Asian countries like Nepal. This chapter gives an overview of traditional medicinal plant Disporum Cantoniense,which is called hadjora (bone-joining) in Nepaliandhasbeen used since time unmemorable in case of bone fracture. Apart from this, D. cantoniense has various other medicinal uses in other regions around the globe. This chapter deals with overall aspects of D. cantoniense with sequential demystification thus enabling a greater understanding of its use and possibility to be used as alternative medicine in the future.©2022Caproslaxy Media.
