UNLABELLED PREMISE OF STUDY Herbaceous perennials are important long-lived plants in North American forests. Trillium has been used as a model organism to examine the effects of ecological processes on age structure in herbaceous forest perennials. Here, the methods of aging Trillium rhizomes are critically examined. • METHODS Rhizomes of seedlings, single-bract plants, three-bract nonflow...

Curcuma oligantha Trimen var. oligantha (Zingiberaceae) is an erect perennial herb with white flowers spotted yellow at the throat of the labellum. It is distributed in Sri Lanka and Karnataka (1, 2). The Curcuma rhizomes are large, tuberous, orangered and aromatic and substituted for turmeric. The rhizomes are prescribed to treat bruises, sprains, skin eruptions, infections and to improve comp...

Vegetative reproduction is a form of asexual propagation in plants. A wide range of plants develop rhizomes, modified stems that grow underground horizontally, as a means of vegetative reproduction. In rhizomatous species, despite their distinct developmental patterns, both rhizomes and aerial shoots derive from axillary buds. Therefore, it is of interest to understand the basis of rhizome init...

Wetlands in the Prairie Pothole Region of North America are integrated with farmland and contain mixtures of herbicide contaminants. Passive nonfacilitated diffusion is how most herbicides can move across plant membranes, making this perhaps an important process by which herbicide contaminants are absorbed by wetland vegetation. Prairie wetlands are dominated by native cattail (Typha latifolia)...

The cold tolerance of winter-dormant rhizomes was evaluated in diploid, allotriploid, and allotetraploid hybrids of Miscanthus sinensis and Miscanthus sacchariflorus grown in a field setting. Two artificial freezing protocols were tested: one lowered the temperature continuously by 1°C h(-1) to the treatment temperature and another lowered the temperature in stages of 24h each to the treatment ...

Background: Inflammatory bowel disease (IBD) is a chronic inflammation of intestinal epithelium driven by intestinal immune system, oxidative stress and loss of tolerance to the luminal microbiota. The use of dietary products containing ingredients like fibers and carbohydrates and/or antioxidant compounds have been used as a therapeutic strategy for intestinal diseases because these products a...

Turmeric (Curcuma longa) is a perennial herb, belonging to family Zingiberaceae. The rhizomes and leaves of turmeric were extracted separately with ethanol by Soxhlet extraction and the percentage yield of rhizomes and leaves of Turmeric was 12% and 17% yield respectively. The extract of turmeric rhizomes and leaves can increase the bile flow, offer protection of the gall bladder and also the l...

Four sterilants–bactericides (Physan-20, Fixed Copper, Phyton27, and Virkon) were compared as preplanting dips of Zantedeschia elliottiana Engl. W. Wats ‘Yellow’ (a susceptible cultivar) rhizomes to reduce plant losses due to latent fieldinfected Erwinia carotovora soft rot during greenhouse forcing as a flowering potted plant. All sterilant solutions were prepared in combination with Promalin,...

Cadmium is a non-essential element that induces various toxic responses in plants when accumulated above the threshold level. The aim of the present research was to study the effect of cadmium on growth factors, concentration of cadmium in the rhizomes and leaves, and quality and quantity of essential oils in the leaves of Mentha piperita L. The experiment was carried out in a completely random...
