Seed Germination

Introduction: Seed germination is a process in which quiescent seeds absorb water and the seed groups stretch out through the seed coat surrounding the embryo. However, most plant seeds do not germinate immediately, they are in a dormant period. These dormant seeds are usually dehydrated, contain inactive enzymes, and are also resistant to adverse conditions. With these characteristics, the seeds disperse before germination and can survive under adverse environmental conditions such as drought.

Seed germination Seed germination is a process in which seeds or spores germinate and begin to grow after a dormant period. The dormancy period depends on the environmental conditions surrounded by the seeds. The environmental conditions that determine when the seed begins to germinate are temperature, oxygen, light intensity, and water supply (Blood, accessed on February 23, 2010, http://www.answers.com/topic/germination) . - INTRODUCTION: Seed germination is a process in which quiescent seeds absorb water and the roots of the seeds grow and pierce the seed coat around the embryo. However, most plant seeds do not germinate immediately, they are in a dormant period. These dormant seeds are usually dehydrated, contain inactive enzymes, and are also resistant to adverse conditions.

Germination of seed mainly depends on moisture and temperature in the environment (El-Keblawy, Abdelfattah & Khedr, 2015). This paper will study seed germination in the context of three different factors. The first one is the temperature. If the temperature is too high, the germinating seed will die (Gorai, Laajili, Santiago & Neffati, 2015). Low temperature also affects seed germination. The second factor affecting seed germination is seed scratching. The third factor related to seed pretreatment germination is immersion in water. In order to obtain the best opportunity for germination it is important to soak the seeds in water before planting (Gorai, Laajili, Santiago & Neffati, 2015).

Germination rate is the proportion of seeds germinated from all seeds under appropriate growth conditions. The germination rate is the length of time required for the seeds to germinate. The seeds' vitality, seed dormancy and environmental impact, which affect seedlings, may affect germination rate and incidence. In agriculture and horticulture, high quality seeds are very feasible and are measured with germination rate plus germination rate. This is given as a percentage of germination over a period of time, for example 90% germination within 20 days. "Sleep" is described above; many plants produce seeds with varying degrees of dormancy, and different seeds from the same fruit can have varying degrees of dormancy. If they are dispersed instantly and are not dry (if the seeds are dry they enter a physiological dormancy state), the seeds can be left in a dormant state.
