The Effects of Lighting on Helianthus Annuus

The Effects of Lighting on Helianthus Annuus
Abstract
The harvest-festival of a plant is affected by the temperature, sunlight, and many other factors. distributively plant grew at their own rates, as shown in the tables be humbled, and was placed in different locations. The different locations varied in the amount light of light each plant received. The temperatures varied between the indoor and outdoor plants. However, all the plants received the similar amount of water. Data was collected from this experiment to determine how lots each factor affected the plants growth.
Introduction
The Helianthus annuus is also cognise as the sunflower. The sunflower is an annual, erect, broadleaf plant with a pissed taproot and prolific lateral spread of surface roots (Sunflower). They domiciliate reach sizes of 1.5-3.5 meters. Moderate temperatures such as 21-26 degrees Celsius are the high hat temperature environments for optimum growth. Temperatures that range from 18-33 degrees Celsius show very little growth affect on the sunflower. The extent of plant growth add or decrease at a certain temperature impart depend on the plant species (Compant et al, 2010). The depth of the seed leavenament affect the way and how fast the sunflower seed grows. A planting depth of 2.5cm-9cm allows sunflower seeds to reach available wet and gives satisfactory stands.



The sunflower is not considered to be highly drought tolerant, but it is an inefficient user of water. The purpose of this experiment is to test if plants will not grow as efficiently as it would if there was sunlight and see if there are low levels of sunlight.
Methods/Materials
During the experiment one of the plants was not watered one daytime out of the week, which should result in no change in the growing efficiency of the sunflower seed. The experiment began with deuce-ace 532 millilitre plastic cups, filled with approximately 266 milliliters of Scotts Turf fertilizer. All three of the plastic cups contained one sunflower seed. The seed was planted 5-6...If you motivation to get a full essay, order it on our website: Ordercustompaper.com
