A seed consists essentially of a seed coat‚ stored food and a young plant‚ the embryo. The seed coat may be made of inner tegmen and outer testa. On the seed coat a scar (hilum) is present which shows the place of attachment of a seed in the fruit is present. At one end of the hilum is the micropyle. Through micropyle the seed absorbs water during the process of germination. The embryo consists of epicotyl‚one or two seed leaves called cotyledons‚ and a hypocotyle. The portion of the embryo above

2. SEED SAMPLING RL. AGRA w.4.L Seed sampling is aimed at obtaining a sample of the required size and consisting of the same components as the whole lot of seeds. The quantity of seed tested in the laboratory is small‚ compared with the size of the seed lot which it is intended to represent. No matter how accurately the laboratory work is done‚ the results can only show the quality of the sample submitted for analysis. Consequently. every effort must be made to ensure that the sample sent to

time that a seed germinates‚ and whether or not it actually does germinate‚ depends on many factors. These factors include; the chemical environment‚ which must be the right conditions; oxygen must be present‚ and inhibitory chemicals must not be present. Germination also depends on the physical environment. Temperatures must be suited to the seed‚ and light quality and quantity must also be suited to the needs of the seed. In some cases‚ all these conditions are met‚ and still‚ the seed fails to germinate

Seed Germination Some people‚ when they think of germination‚ think of a seed sprouting. Very plain‚ simple image in their mind‚ especially since there is so much more going on in the small seed. New Life is growing. Germination is the sprouting of a seed‚ through which a lot of plants reproduce‚ though not all. Water is a major trigger in the germination stage‚ playing a major role also later in the plant’s life. Though seeds are not the only way for plants to reproduce‚ it is one of the easiest

Effect of seed germination Purpose: To see the effect of an acid introduced during seed germination‚ on the length of the plant roots. Also shows how salt can affect the seed germination. Acid can be introduced to seeds during germination if there is acid rain. Knowing the results of acid rain on seed germination will help us understand how to grow pants better‚ and how to have more successful germination. Salt can be introduced into a seed during germination because salt is put on roads and the

Bt corn is a genetically modified organism‚ often referred to as a GMO. “A GMO is a plant or animal that has been genetically modified through the addition of a small amount of genetic material from other organisms through molecular techniques.” (Bessin‚ 1999 rev. 2004‚ p.1). The production of GMO’s came about because of the need to provide a form of
