Crabgrass and goosegrass are problematic weeds in creeping bentgrass due to their ability to proliferate in the transition zone. These weeds are able to survive low mowing heights, especially among cool-season grasses (Busey, 2003; Callahan, 1986). As herbicide resistant populations of crabgrass and goosegrass increase and as cultural control methods have proved ineffective in cool-season grasses, new herbicides will be needed to ensure future control (Busey, 2003; Callahan, 1986; Hart, 2004; Mudge
Dancing in Dandelions The dandelion is a plant many of us have become familiar with over the years. The golden flower clutches our lawns, highways and byways. Successful strategies for survival have given the dandelion a foothold in our lawns, if not in our hearts. Several individuals have fond remembrances of gathering the flower as a child, and it became the all-American symbol of a "mother's first bouquet." Yet as an adult, the plant is likely to become a distinct target when bending down to
Plant collection report Family: 1. Asteraceae The common species include daisy and sunflowers for ornamental; lettuce for crop; ragweed and thistles for weeds. Most plants of Asteraceae are herbaceous plants, but climbers, trees and shrubs do exits. most of the Asteraceae members produce taproots, but some of them also have fibrous root systems. The leaves can be alternated, opposite or whorled. The common plant characteristics of Asteraceae include having “composite” flower heads composed of many
Chamomile as a form of alternative medicine, the properties of chamomile, as well as the precautions, risks and monitoring parameters associated with using Chamomile. Chamomile is one of the most ancient medicinal herbs used today. It is a member of the Asteraceae/Compositae family and comes in two different forms- German Chamomile and Roman Chamomile. Historically, the origin of the name Chamomile can from the Greeks who first noted that the smell resembled that of apples and therefore named it “ground apples
Fabaceae or Leguminosae is a large and economically important family of flowering plant. It is commonly known as legume family, pea family, bean family and pulse family. Fabaceae is third largest family of flowering plants behind Orchidaceae and Asteraceae, with 730 genera and over 19400 species according to Royal Botanical Gardens and Acacia with 900 species. Tree grows up to 8 m in height, with umbrella-shaped or flat or rounded crown (Maundu et al., 1999). It is based chiefly on characteristics
The purpose of this essay is to explore some of the mechanisms involved in the seed dispersal in plants. Plants are some of the most ancient biological organisms on the planet, and over the millennia they have adapted to utilise both the natural resources of the earth and the animals on it in order to spread their seeds. Without a variety of processes plants would be restricted to localised geographical areas, and this would limit their populations. This essay discusses some of the major ways that
Our walk began at the entrance of the Queens Botanical Garden where we observed a tree that had been present there for quite some time. In front of the garden’s entrance on Main Street there is a tree sculpture that was built in 2002 in dedication to the victims and heroes of 9/11. Also I noticed that the garden's perimeter is enclosed by a steel fence that has the garden’s name and the native plants to that area inscribed on the panels of the fence. The weather that morning was very cold and we
The Sunflower The Helianthus Annus is classified as follows: Common name- Sunflower, Garden flower, or common Sunflower Phylum: Tracheophyta Class: Magnoliopsida Order: Asterales Family: Asteraceae Genus: Helianthus Species: Helianthus annuus The Sunflower is my favorite flower. One of my reasons for choosing the sunflower was its striking beauty, from its long fuzzy stem to its beautiful golden petals that resemble the rays of the sun. Another reason why I selected the sunflower is because of
INTRASPECIFIC COMPETION: THE RESPONSE OF THE SUNFLOWER (genus HELIANTHUS) TO INCREASING DENSITY. INTRODUCTION All species, including plants, are impacted by density. Plants, of course, cannot leave their habitat as animals can, so they tend to respond in different ways to density. As populations grow more dense, they compete for resources such as food and space and are more prone to disease. Less dense populations are more susceptible to predation pressure. It is hypothesized that as plants in
Do you know how are the animals divided? Do you know how many kinds of animals are there? Not every animals are the same kinds, there are over millions of organisms on top the sky, under the ocean, and on the ground, there can be animals on top of the Horizon one million km and down one million km. So scientist want to make it more easier, they group the animals into thousands of group, and they also make a chart, so that if there are a new animals , then they can know what kind of animal it can
The Common Name: Marigold, Calendula The Botanical Name: Calendula Officinalis The Family: Asteraceae Family The predominantly part of the Calendula that is the petals however the leaves are sometimes used is capsule form. Flavonoids anti-oxidants chemicals in the body are found in high proportions in calendula, this help protect the body cells for oxidation. Oxidation produces natural chemicals that can reduce the effectiveness of the immune functionality. Calendula is beneficial in the following
Before humans ever roamed the Earth, many unique and strange life forms roamed the Earth such as dinosaurs and gymnosperms. They learned how to adapt to the changing and an unstable atmosphere of the Earth before it became what it is today. At the same time, the plants were also quite a discovery in the fossil record. The plants grew immensely and were quite plentiful for the herbivorous that roamed the Earth. However, there was one particular group of plants that eventually took over as the leading

Trends In Economic Botany: The Rising Use Of Herbal Supplements The use of herbal remedies to treat health problems in humans is a tradition that dates back many centuries. A precursor to modern, Western pharmaceuticals, traditional healers used herbs to treat a wide range of ailments and afflictions. While many are familiar with their use by American Indians, the practice of herbal therapy dates back to ancient Chinese and Egyptian healers. Herbs were used in ancient times to treat anything
Diverse Australian Biomes Adapting Australia is a land of rather extreme weather conditions and widely diverse climates that force the vegetation living there to adapt in many interesting ways. Australia is the driest continent, and biomes such as grasslands and savannas are prime sources of widespread catastrophic fires. The plants that grow in the vast arid and semi-arid regions of Australia are prone to fires simply because of the desert climates that they grow in. High temperatures combined
WHAT IS A DESERT? Desert is a dry region with little or no vegetation and is found throughout the world. These places have plants and animals too, that have adapted to surviving on little water. Deserts are not necessarily hot, but they can be cold as well. There are different types of deserts. What makes a desert a desert? Deserts are deserts because they lack water. It rains so rarely in a desert that some deserts even go two years without a drop of rain. The soil is so dry and hot that sometimes
