BUDS - How they open.
Buds are organs. Buds are structures that are made up of embryonic shoots. Starch is stored at the end of the previous growing season at the base or behind of the bud. If this starch is not stored or the starch is not there in abundance in the spring, the bud will not open.
When starch is converted back to glucose the water molecule is added back.
Sample to right was stained with I2-KI (iodine in potassium iodide) that stains starch grains purple.
Some Myths and half truths still in text books and being taught.
Myth 59. TO OPEN, BUDS REQUIRE FOOD FROM ROOTS. Energy in the form of starch or other reserves are at the bud base the growing season before the bud sprouts. Roots provide water and elements. A tree can be cut in October or November in the north and the cut end put in a stream or pond. The next spring, the leaves, flowers, and sometimes even fruit will form on the tree. It is common practice to force twigs of flowering shrubs and trees. Roots require all the energy they can store to support their root growth.
