Aground A seed Is d small embryonic plant enclosed In d covering called the seed coat, usually with some stored food. It Is the product of the ripened ovule of gymnosperm and angiosperm plants which occurs after fertile;talon and some growth within the mother plant. The formation to the seed completes the process to reproduction in seed plants (started with the development of flowers and pollination), with the embryo developed from the zygote and the seed coat from the integuments of the ovule.
Seeds serve several functions for the plants that produce them. Key among these functions are nourishment of the embryo, dispersal to a new location, and dormancy during unfavorable conditions. Seeds fundamentally are a means of reproduction and most seeds are the product of sexual reproduction which produces a remixing of genetic material and phenotype variability that natural selection acts storage of reserves food Is one of the mall functions of the seed. Outrage of serves Todd is closely related to the process to ripening and seed tilling. Knowledge of this is necessary as a preparation of the breeder in order to produce seeds seed which has the power and speed of germination (viability) is high. In the process of ripening and seed filling are the factors that affect the optimum level of process. These factors are internal factors derived from the plant (seed) itself and the external factors which is more oriented to the environment. 2. Practical purposes.
The purpose practical of Part I are: a. Find out growth processes and development of flowers and seeds, b. Find out seed production process.. 2 Practical methods 1. Tools and Materials a. Tools 1) vases 2) Shovels 3) Growing medium b. Materials 1) Peanut seeds (Archaic hypoxia) 2) Green beans (Phase-out radiates 2. How to Work a. Setting up a vase and planting medium (soil: compost: manure) in the ratio b. Plant the seeds in the vase, for one vase contains 3 seeds, c. Taking care of each day and observe the stages of growth, d.
Observe the process of seed production stages: flowering time, flower structure, time from flower to seed, time from seed to harvest and the seed structure. 3 Observation results Table 1. 1 Development of Peanut Seeds and Green Bean Seeds Commodity Root length Plant height I number of pods I The number of I number of I I (CM) appear I Peanut I Green Bean Sided in a pod Fruit Sources: Interim Report bloom Figure 1. 1 Peanut Flower I Flower bud I Flower Figure 1. 2 Green Bean Flower
