seed

Seeds are an important food source for animals andhumans. Have a seed is one of the characteristics of plants Spermatophyta. For Spermatophyta plant seeds

is a major breeding tool. Because the seeds contain apotential new plant or institution. Seeds develop fromthe ovule. With the production of seed plants canretain its kind.

Parts - the germination:

1. Radicle

2. Cotyledons

3. Cauliculus4. Hipokotil: Bar located at the bottom of thecotyledons

5. Epikotil: steam located at the top of the cotyledons6. Testa: That is the growing of one or twointeguments, nuselus (occasionally)

Development of seeds is affected by five things:1. The influence of seed development is influenced by thenumber of bacteria in the process of nitrogen fixation inthe nitrogen fixation cycle.

2. Different climatic conditions.3. The use of NaCl, Na2SO4, and Mannitol in the use of protein storage vacuoles in seeds and changes in the seed(cotyledons)4. Effect of amino polysaccharides in the growth of seed

layers.5. Character with the planting of radiation sensitivity andgrowth genes.

In the process of breeding seeds usuallyundergo a process called germination.Germination is the initial stage of 

development of a plant, especially seedplants. In this stage, the embryo in the seedwhich was originally in a state of dormancyundergone a number of physiological

changes that cause it to develop into youngplants. These young plants are known as thesprouts. One example is soybeans.

Dressing soybean seeds for their protection

against diseases has already been done for more than 50 years.

In a specially conducted experiment, we

added to the nutrient medium TMTD (40%

water suspension concentrate) (Table 1).

Longterm testing of insecticidal dressings of the carbofuran series showed their very

high effectiveness against soybean root

Consequently, slowgrowing B. japonicum

strains are more sensitive to chemical

preparations than fast growing S. fredii strains

 After germination in water for 2 days the

cotyle day-to-4don released from the seed

coat and has a greencolor. The process of 

gradual transformation of specialized storage

vacuoles occur in mesophyll cells of 

cotyledons of seedlings grown.

AminoPolysaccharides enhance photosynthesis,

promote and enhance plant growth, stimulating

nutrient uptake, increased germination andgrowth, and increase the power plant. When used

as a seed treatment on cotton that raises an
