on Seed Germination The reproductive cycle of a plant is a process of constant development. It begins with gamete formation‚ and after several other steps leads into germination. During germination a mature seeds beings the formation of a seedling (Freeman 2011). However‚ before germination the seed is in a state of dormancy‚ therefore the seed must have a favorable environment to disrupt the dormancy (Freeman 2011). There are several indications for the seed to being germination. All seeds require

Abstract Moringa seeds are known to contain an antimicrobial substance‚ which gets rid of microorganisms that suppresses growth. This investigatory project aims to prove that Moringa seeds can be used to purify contaminated water. The benefits of this investigatory project is that the purified water may be used in our everyday lives‚ may help in the preservation of water‚ fewer expenses would occur and adds knowledge towards the purification of water. In this experiment‚ Moringa seeds‚ a mortar‚ a clean

Does the concentration of salt in the water‚ affects the germination of the seed? Purpose: To see if the salinity of the water affects the germination of the seed‚ before its put into the soil. Back Ground Information: Seed germination is the sprouting or growth of a seed into the start of a plant. When environmental factors such as moisture‚ temperature‚ oxygen‚ and sometimes light are appropriate‚ a viable seed will begin to germinate. Salinity (salt-affected) in plants can cause ionic

raw sugar in the soil surrounding a seed during the first 2 weeks of its life affects its growth. We proposed that it would help the plant because one of the results of photosynthesis was a product of sugar. We thought that perhaps a raw sugar would be absorbed through the roots and provide the plant with more energy. We chose Turbino sugar as our raw sugar. Procedures: 1. Form a hypothesis. 2. Soak the Mung beans for around 24 hours to loosen the seed coats. 3. Make the water/Turbino solutions

number of genus Helianthus (sunflower) seeds in pots to see how they respond to increased density in limited space. Two replicates each of 2‚ 4‚ 8‚ 16‚ 32‚ 64‚ and 128 seeds were planted in similar size pots containing an equal mix of potting soil and perlite. All plants were kept in greenhouse conditions exposed to similar light and temperatures settings and were watered at equivalent intervals. At the end of the time period each pot was evaluated for number of seeds that had germinated as well as number

Sodium Chloride (NaCl) solution were created and the effects that they had on radish seeds were tested. This ultimately created a doseresponse experiment in which it was detectable whether or not radish seeds were a reliable bioassay for the toxicity of NaCl. The goal of this experiment was to determine a correlation between toxicity and seed germination/radicle length. Our data indicated that seed germination decreased as concentration increased‚ demonstrated

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 of fleshy leaves rich in jellylike pulp‚ as well as
