|
stop all further growth
|
|
|
promote the production of new axillary buds, making the plant bushier
|
|
|
make it grow taller, faster
|
|
|
prevent the plant from getting thicker, making it floppy
|
Detailed explanation-1: -The apical bud produces a hormone called Auxin which inhibits the growth of the lateral buds. When the apical bud is removed from the plant, the Auxin gets automatically removed and due to which the lateral buds grow very fast and make the plant bushy in nature. So, the correct answer is option A i, e Bushy.
Detailed explanation-2: -After apical bud removal, the plants formed lateral shoots, which eventually lengthened and strengthened considerably. The majority of plants developed from two to three lateral shoots, with only a few forming four to six such shoots.
Detailed explanation-3: -Pruning is done to remove apical dominance in plants. b. When plants are decapitated, removal of apical bud results in growth of lateral buds which gives bushy appearance to plants. c. Thus, pruning is done to encourage growth of more shoots with softer leaves.
Detailed explanation-4: -Apical dominance is the process whereby the shoot tip inhibits the growth of axillary buds along the stem. It has been proposed that the shoot tip, which is the predominant source of the plant hormone auxin, prevents bud outgrowth by suppressing auxin canalization and export from axillary buds into the main stem.
