Germination of bean seeds
Beans grow outdoors during the long, warm days of summer when they are in no danger of frost exposure. Sprouting the seeds indoors for immediate transplanting in early summer can help ensure more even germination and less wasted seed. You can also sprout the seeds without soil on a paper towel to check the viability of old bean seeds or saved seed before you plant. Fold the towel over to cover the top of the seeds.
Press the top of the towel so the seeds are in full contact with the damp towel on both sides of each seed. Count the number of sprouted seeds to determine the viability rate. Germinating bean seeds on moist kitchen paper towels is a simple and more successful starter method. Make germination box: Use a pin to prick small holes at 4 corners, about 12 mm (0.5 inch) from top and from side. Drill holes at those positions. Put in satay sticks. Shorten satay sticks using scissors.
Regularly check water level as follows: Hold the box somewhat slanted. Water level is okay when a little water appears in the corner within 2 to 10 seconds. The seed of a dicotyledonous plant has three main parts: Table of seed components StructureFunctionSeed coata tough protective outer coveringEmbryoconsisting of the young root and shoot which will develop into the adult plantFood storea store of food (starch) for the young plant to use until it is large enough to make its own foodGermination is the start of growth in the seed.
The most common example of germination is the sprouting of a seedling from a seed of an angiosperm or gymnosperm. In addition, the growth of a sporeling from a spore, such as the spores of hyphae from fungal spores, is also germination. Thus, in a general sense, germination can be thought of as anything expanding into greater being from a small existence or germ.
The radicle then emerges and starts its downward growth into the soil. In the bean ( Phaseolus vulgaris) seed the hypocotyl elongates and straightens, raising the cotyledons above the ground. A garden is a wonderful place to learn about life and growth. A dry seed in the hand looks insignificant. Yet inside is a plant-to-be. The embryo has all of the basic plant parts. As the seed begins to grow, its epicotyl or plumule will form the plant shoot.
