Each has a different appearance and the seed is the primary part of the plant we eat. Dormant seeds can wait months, years, or even decades for the proper conditions for germination and propagation of the species. divided into four categories related to their longevity and abil - ity to be stored (Hong and Ellis 2002, Kettle and others 2011). Fertilize regularly but lightly. If your child has understood the thought process mentioned above, he/she would most probably be thinking that a larger seed would have larger seed leaves. Using good quality seed is the only criterion to get high yield. Sowing is the placing of a specified quantity of seeds in the soil in the optimum position for germination and growth while planting is the putting of plant propagules (may be seeds, seedlings, cuttings, tubers, rhizomes, clones) into the ground to grow as crop plants.
