production. Seed treatments protect soybean seed and young soybean plants from diseases and other threats to plant health and yield. Variety selection. No soybean variety is completely resistant to powdery mildew, but some varieties are much more susceptible than others. It’s difficult for companies to evaluate and breed for resistance because, in most years, powdery mildew pressure is low or nonexistent in soybean fields. It’s always wise to plant-disease free seed. Good weed control from…

about how plants cannot survive in total darkness and how darkness &light affect the growth of a plant in different ways. Plants cannot survive in total darkness as they use the suns energy and through a process convert it into food, this process is called photosynthesis. The plants that need sunlight to survive, which are majority of plants are called autotrophs. The presence/absence of light and dark play an important role in a plants as they trigger metabolism, growth and behaviour in a…

The“Marijuana” is an ancient plant which is known to have been used long before it was recorded by man as early as 6000 B.C, by the ancient Chinese when the seeds of the plant were used as food. It is believed that the word Marijuana came from the Portuguese word marigu-ana, which means "intoxicant”. And some believed that it was originated from Mexican Spanish, which means ‘To get high’ or ‘Prisoner’ (Martin booth, Wikipedia, 2014). Marijuana is also known by other words such as “cannabis, weed…

in every ecosystem. Bacteria for instance have a mutualistic relationship with Legumes. Specifically, the bacteria Rhizobia. When the bacteria enters the root, ammonia is created from the nitrogen in the air. And from this, the plant uses it to create amino acids. The plant then provides sugar for the bacteria. A parasitic relationship between bacteria and a human host would be the bacteria Mycobacterium Tuberculosis. This bacteria is known to be extremely contagious and deadly to humans,…

Linum usitassimum is an annual herb belonging to the family Linaceae. The plant is indigenous to west Asia and the Mediterranean. Seed oil of this plant used commercially in the painting and varnishing due to its polymerization properties when exposed to the air and sun light. It is also used as an astringent in fungicidal lotion and an insecticide. Seed oil are reported to rich in essential fatty acids like omega-3- fatty acids (linolenic acid, 35-67%), omega-6- fatty acids (linoleic acid,…

Meanwhile, in the in vivo tests, treatment with Kemazed decreased disease incidence of leaf spots on potted plants to 16.67% compared to 100% for the untreated inoculated control. On the other hand, the bacterial and fungal biocontrol agents tested proved to be effective against the dracaena leaf spot fungi. The in vitro assays conducted showed that the bacterial…

Introduction Pigments is defined as a organic compounds that give a characteristic color to plant or animal tissues and is involved in critical processes. Chlorophyll in plant (photosynthesis) and hemoglobin present in Red blood cells (oxygen transportation) are examples of pigment. Variety of color pigments produced by organisms is also known as biological pigment or bichromes. Pigments from plants and animals have been obtaining since long time ago, and used as natural colorants in many…

Hypothesis 2: Calcium levels in the soil affect species richness. Prediction: An increase in the calcium levels in the soil will decrease the species richness. Reasoning: As the calcium levels increase, some plants begin to take advantage of increased calcium levels and outcompete other plants, driving them to extinction. Thereby, decreasing species richness. Analytical approach: Regression Independent variable: Calcium levels Dependent variable: Species Richness By signing, I acknowledge that I…

is a free- floating aquatic plant from the duckweed family, that consists of small, individual thalli (Tkalec et.al, 2001). Lemna are small, fast growing plants and they develop dense mats on ponds, especially when enough light and nutrients are available (Gérard et.al, 2014). Salt is the most toxic substance, as it causes an inhibition of plant growth and a decrease in nutrient uptake (Chang et.al, 2012). Salt stress induces the production of abscisic acid (ABA), a plant stress hormone, which…

competition), and also reduce greenhouse gas emissions. There are many methods that fit under those criteria have been researched in addition to algae based biofuels; a few of the most prominent are: (1) perennial plants, (2) crop residues, and (3) double cropping systems. Perennial plants. In 2006, Tillman et al. published an article detailing their experiment to test the feasibility of using low-input high-feasibility (LIHD) mixtures of grasses as a means for biofuel. These researchers…
