When the apical bud
of aging trunks is cut at the ground, it kills that stem but stimulates the growth of new stems in the clump.
Auxin (indole-3-acetic acid), a plant hormone is synthesized in the youngest leaves of the apical bud
If the apical bud
remains undamaged, the plants grow fairly symmetrically and begin to compete with each other for space in the row.
The needles (up to 9 inches on mature longleaf), form a protective heat barrier around the apical bud
, nestled at the base of the fragile-looking seedling.
Cutting the terminal or apical bud
on any shoot means removing the source of hormones that inhibit lateral branching and ultimately more shoot tips, means more blooms in the spring - especially on roses and other terminal flowering species - than if the plants were left alone.
However, some stems remained green and developed new shoots at the ground level or the apical bud
began to grow again.
Auxin (indole acetic acid), a plant growth hormone, is synthesized primarily in the apical bud
The plant hormone auxin (indole acetic acid) is produced primarily in the youngest leaves of the apical bud
Decapitation and hormone manipulation experiments have shown growth control of the lower buds by the shoot apex is due to the plant hormone auxin (indole acetic acid) which is produced primarily in the youngest leaves of the apical bud
Later instar larvae leave the mines and bore into stalks, apical buds
, and fruits (Ferracini et al.
CBSV was detected in flowers, fruits, apical buds
, young tender leaves, newly open leaves, youngest symptomatic leaves, tender-top green stem portions and non-necrotic storage root tissues.
When potato plants grew sufficiently, the apical buds
were removed with an aim to grow lateral buds and produce more branches.
