Treated seedlings are healthier, more vigorous after transplanting The quality of agricultural seedlings is important to crop growth and yield after transplantation. Good quality seedlings exhibit characteristics such as thick stems, thick leaves, dark green leaves, and large white roots. Scientists have long known that plant development and physiology are strongly influenced by the light spectrum, which affects seedling structure. Raising seedlings irradiated with blue light has been...

Fluorescent, metal-halide lights tested for effects on sweet potato whitefly resistance In horticultural production, growers often depend on systems that use artificial light to produce high-quality transplants. Although the systems are efficient, fluorescent lamps can produce plants with shorter shoots than those grown under natural light. Studies have indicated that this reduced shoot elongation is due to the high red:far red ratio of typical commercial fluorescent lamps, which emit little...

HARRISBURG, Pa., Jan. 24, 2011 /PRNewswire-USNewswire/ -- Pennsylvania Game Commission Executive Director Carl G. Roe today announced the agency again will be helping Commonwealth school students learn about the vital role of trees in the environment through its "Seedlings for Schools" program, in which students will be able to plant a variety of tree seedlings at home, on school grounds or in his or her community. "There is no charge to schools participating in this project, as the...

A team of researchers from Duke University and the Salk Institute for Biological Studies has found a central part in the machinery that turns plants green when they sense light. In the Rube Goldberg world of cellular mechanics, this key player turns out to be a garbage truck. Light is so essential for plants that they have two different systems to take advantage of it, explains Meng Chen, an assistant professor of biology at Duke. There's the familiar system of organelles called chloroplasts...

For a plant, light is life. It drives everything from photosynthesis to growth and reproduction. Yet the chain of molecular events that enables light signals to control gene activity and ultimately a plant's architecture had remained in the dark. Now a team of researchers from the Salk Institute for Biological Studies and Duke University have identified the courier that gives the signal to revamp the plant's gene expression pattern after photoreceptors have been activated by light. "Light is...

Power struggle between genetic master switches decides stem cell fate, growth orientation in plants The first order of business for any fledgling plant embryo is to determine which end grows the shoot and which end puts down roots. Now, researchers at the Salk Institute expose the turf wars between two groups of antagonistic genetic master switches that set up a plant's polar axis with a root on one end and a shoot on the other. "In what is arguably the most important decision for a plant,...
