Kentucky bluegrass is a versatile cool season perennial grass that adapts to a wide range of soil pH‚ soil texture‚ and microclimate within temperate climate zone. The ideal growing conditions are well-drained fertile soil with medium texture‚ and humid temperate regions. Kentucky bluegrass can tolerate soil pH from 5.4 to 7.3‚ however‚ studies carried in Central Oregon indicated optimal performance when soil pH is between 6.2 -6.8 (Butler 2002). Kentucky bluegrass has low tolerance for saline

d.) Control variables: temperature‚ mass of seeds used‚ and volume of chamber. Part 2: Germinating seeds in cold water Hypothesis: Low temperature will make cellular respiration rate smaller. Part 3: Germinating seeds at different days of germination Hypothesis: seeds that germinating longer will have higher cellular respiration. III/ Results: Part 1: At 210C‚ 10.8 grams of each type of seeds were used. The rate of respiration of - Germinating seed is 92.58 ppm/min - Non- germinating

Eugenia B. Tomas K-8 Center Science Fair “Plants Growth investigation” Student: Daniela Tristan. Teacher: Mrs. Pena. 2010. Title of the project: Plants Growth investigation Abstract: The purpose of this experiment is that by watering more a plant will help it grow more or less. I hypothesized that the plant that will grow the most will be the plant that will be watered the most. Hypothesis If a plant given an unlimited supply of moisture will grow more rapidly than

The purpose of this experiment was to discover if using sugar and tonic water with water would increase the growth rate of barley. In this experiment‚ we changed two variables‚ the independent variables sugar and tonic water. We added one tablespoon of each substance to four ounces of water which will be used to nourish the plant. We tested these experimental controls to determine if any of the substances would help accelerate the growth of the barley. If the sugar water or tonic water mixture successfully

The Centers for Disease Control concluded that all this was a result of the chicken salad not being stored at the proper temperature. Germination began to occur‚ and large colonies of the bacteria developed within the chicken salad. Through my research‚ I’ve found that the seemingly best way to prevent Clostridium perfringens is to properly store and cook food. I feel that if we were

Lab Report: How Do Different pH Levels Affect The Growth of Plants Introduction: Plant growth is affected by various environmental factors‚ and pH is one of those. The pH of soil and the water that plants receive can have an impact on whether they obtain nutrients or not. Ph impacts the chemical reactions that take place within a plant‚ if the pH of the soil or water that the plant receives is too low (acidic)‚the nutrients that the plant requires may become extremely soluble to the point where

Africa‚ including Morocco‚ Egypt‚ Mauritania‚ but nowadays it’s cultivated throughout the world for both medicinal and aesthetic purposes. Basically‚ this plant is grown as an ornamental plant (Boudreau & Beland‚ 2006). Life Cycle of Aloe vera Germination of aloe seeds occur when their seeds come in contact with warm and moist soil‚ after which a seed-root that anchors the plant to the ground emerges. The heat of the summer facilitates the growth of Aloe vera by stimulating the development of a rosette

Bacillus Cereus Bacillus cereus is a rod-shaped gram- positive bacillus that can be found in food‚ dust‚ dirt and sometimes soil. It is an aerobe and a facultative anaerobe that can form spores‚ which if activated at any point can begin to germinate and produce toxins. These spores that form from B. cereus are be resistant to heat and chemicals. B. cereus is found in approximately 25% of food sampled (3). Foods that are commonly associated with B. cereus are potatoes‚ rice‚ meat‚ vegetables
