Greenhouse bedding plant growers can save themselves time, money or possibly both by giving cuttings in propagation more light, according to a Purdue University study. Flower growers use cuttings from Central America and Africa to start spring bedding plants in greenhouses during winter and early spring. Those cloudy days and cool temperatures make propagation time- and energy-intensive. Roberto Lopez, an assistant professor of horticulture, and horticulture graduate students Chris...

Scientists Discover New Carnivorous Plant In Brazil
2012-01-10 14:02:11

In the kind of discovery seldom seen in modern biology, scientists say they have discovered a carnivorous Brazilian plant that uses sticky, subterranean leaves to catch and digest worms–an evolutionary strategy for acquiring nutrients that has never before been observed in the plant kingdom. Researchers say that the rare plant, known to scientists as Philcoxia minensis, has only been found in a handful of increasingly rare savannah regions in inland Brazil. In a report of their...

The Biological Sciences Social Network Life-Sciences.net features the latest scientific publications in Biology. The most recently featured articles deal with a spectrophotometric method for determining polysaccharides in Echinacea purpurea and In vitro plantlet production of the endangered Pinguicula vulgaris. These as well as all other articles are now available on a new website dedicated to mobile viewing. (PRWEB) December 28, 2011 The Biological Sciences Social Network Life-Sciences.net...

In a major effort to speed up the process of officially recognizing new plant species, botanists will no longer be required to provide Latin descriptions of new species, and publication in online academic journals and books will be considered as valid as print publication. The new rules, which were approved at a nomenclature conference held in conjunction with the International Botanical Congress in July, become effective January 1, 2012. They overturn longstanding historical requirements...

Biologists have learned in recent years that wild chilies develop their trademark pungency, or heat, as a defense against a fungus that could destroy their seeds. But that doesn't explain why some chilies are hot and others are not. New research provides an answer: Hot chilies growing in dry areas need more water to produce as many seeds as non-pungent plants, but the Fusarium fungus is less of a threat in dryer environments so chilies in those areas are less likely to turn up the heat. In...

Plant roots are fascinating plant organs — they not only anchor the plant, but are also the world's most efficient mining companies. Roots live in darkness and direct the activities of the other organs, as well as interact with the surrounding environment. Charles Darwin posited in The Power of Movement of Plants that the root system acts as a plant's brain. Due to the difficulty of accessing root tissue in intact live plants, research of these hidden parts has always lagged behind...

Genome Tree Of Life Is Largest Yet For Seed Plants
2011-12-17 04:26:21

New York Plant Genomics Consortium maps evolutionary relationships, gene functions for 150 species Scientists at the American Museum of Natural History, Cold Spring Harbor Laboratory, The New York Botanical Garden, and New York University have created the largest genome-based tree of life for seed plants to date. Their findings, published today in the journal PLoS Genetics, plot the evolutionary relationships of 150 different species of plants based on advanced genome-wide analysis of gene...

NYBG scientist says the plant world has "great potential" as a source of new medicines There are probably at least 500 medically useful chemicals awaiting discovery in plant species whose chemical constituents have not yet been evaluated for their potential to cure or treat disease, according to a new analysis by a New York Botanical Garden scientist who has more than 15 years of experience in collecting plants for natural-products discovery programs. Currently, 135 drugs on the market...

Tomato, watermelon prove most efficient at CO2 accumulation Salt can have drastic effects on the growth and yield of horticultural crops; studies have estimated that salinity renders an about one-third of the world's irrigated land unsuitable for crop production. Imbalances in soil salinity can cause ion toxicity, osmotic stress, mineral deficiencies, and drastic physiological and biochemical changes in plants. Salt stress can even cause plants to adjust their water usage–to conserve...

Researchers report that they have uncovered and analyzed human bedding believed to be 77,000 years old. The bedding material gives a look into how humans lived in South Africa. Lyn Wadley of the University of the Witwatersrand in Johannesburg, South Africa says, “Domestic activities, like preparing and destroying plant bedding, can provide important information.” Some of the important information provided in the plant-based bedding materials, according to the National...

Dawsonia
2013-11-04 10:01:23

Dawsonia is a classification of mosses. This genus is a member of the Polytrichaceae family. Dawsonia plants are commonly known to grow taller and have thicker leaves than other common mosses. Mosses are known to grow when hydrated, however most common mosses lack cuticles and internal transport tissues. This makes it difficult for them to maintain substantial amounts of water and they typically do not grow tall. Dawsonia are an exception to this common rule. Dawsonia mosses are...

Petrified Forest National Park
2013-04-24 16:53:26

Petrified Forest National Park is located in the state of Arizona in the United States. The park holds 221,552 acres of land, of which 50,260 acres are comprised of a designated wilderness. The area was once inhabited by Native American tribes including the basket maker and pueblo peoples. The first American explorers to enter the area arrived while searching for good routes leading from east to west. This group, led by Army Lieutenant Amiel Whipple, surveyed the northern area of the...

The Whisk Fern (Psilotum nudum), is a genus of fern-like vascular plants, one of two genera in the family Psilotaceae, order Psilotales, and class Psilotopsida (the other being Tmesipteris). The distribution of Psilotum is tropical and subtropical, in the New World, Asia, and the Pacific. The highest latitudes known are in South Carolina and southern Japan for P. nudum. In the U.S., one species is found from Florida to Texas, the other in Hawaii. They had traditionally been thought not to...
