ABSTRACT Factors affecting germination are numerous and well studied (soil nutrient composition, water availability, temperature, etc). Others, such as seed size and its effects on the duration of seed germination have been largely unstudied. In this study, seeds from the plants P. vulgaris and L. culinaris were studied to observe any differences in the duration of germination, with P. vulgaris being the larger seed species. The data revealed that seeds from the L. culinaris took a shorter period

1. Introduction Germination is the process in which we awaken the embryo, increases seed metabolism and toggles the massive reproduction that causes a new plant to grow. The main mechanism that triggers this process is simply liquid water. When water gets into the embryo and hydrates its cells, it speeds up metabolism and allows the process of cell division and growth to rapidly increase. However it is not always simple to start this process since several impairments both chemical and physical –

Seed Germination Seed germination is the process in which seeds or spores sprout and begin to grow after being dormant for a period of time. The length of dormancy varies depending environmental conditions in which the seed is surrounded by. The environmental conditions that determine when a seed will begin to germinate are the temperature, oxygen, the amount of light, and the supply of water (Germination, accessed 23 February 2010, http://www.answers. com/topic/germination). For a seed to begin

Introduction: Seed germination is a process where the quiescence seed imbibed with water, the seed radical elongates and breaks through the seed coat surrounding the embryo. However, most of the plant seeds do not germinate immediately and they under goes period of dormancy. These dormant seeds are normally dehydrated, containing inactive enzymes and resistant to unfavorable condition. These characteristic allowed the seed to be dispersed before germination occur and survive adverse environmental

“Germination is a process in which a seed or spore awakens from dormancy and starts to sprout” (WiseGEEK). Plant germination can definitely vary if it is grown in different conditions, but I am investigating how plant germination will be impacted by the presence of other plants. I predicted that broccoli will have a positive impact on germination of lettuce seeds. To do this, I had two groups an experimental group and a control group. Both groups were provided with similar temperature, sunlight and

Seed Germination and Temperature Introduction Seed Germination is the process by which an organism grows from a seed into a plant such as an angiosperm or gymnosperm. Temperature is a factor that can highly effect the germination of a plant. Squash is recognized in the family Cucurbitaceae. Squash come in different varieties, usually distinguished as being “winter” or “summer” squash (Maynard, 2003). It is actually said that summer squash is harvested when the fruits are immature (New World Encyclopedia

controlled, but the water is poured into Pyrex 600ml beaker. The water from the beaker is used for watering all the samples. This way the water temperature is same for all samples. The temperature of water will not have an effect on the rate of germination, because samples have same circumstances throughout the experiment. Sucrose

perfect conditions. In the field of botany, this phenomenon is known as “physiological seed dormancy” (will be referred to as PSD from here on out). In plain language, PSD is like a “hibernation” stage that occurs after seed maturation but before germination. After the seeds of a mother plant mature, they respond to environmental cues that signal the end of the growing season is near and begin PSD (hibernation). If the seed did not enter this dormancy phase, it would attempt to grow as soon as it

Optimal pH Levels for Radish Seed Germination Question Do radish seeds germinate best in neutral, acidic or alkaline solutions? Introduction Germination is the reestablishment of metabolic processes in a seed after a period of dormancy. The germination process varies for different seed varieties. Generally, germination begins when water causes the outer covering of the seed to loosen. The uptake of water by the seed triggers the release of hormones needed for respiration, protein synthesis,

Effect of Acid Rain on Germination A seed is formed from the ovule of a flower as a result of fertilisation, and is then dispersed from the parent plant. If the seed lands in a suitable place, it will germinate. Germination is the growth of the embryo inside the seed, eventually growing into a mature plant. CONDITIONS NEEDED FOR GERMINATION OXYGEN - is used for aerobic respiration, which provides the energy for many chemical changes involved in the food reserves and making the new
