(2016) water status, especially water stress, is also a major factor that has an impact on the grapevine flowering process, in particular on latent bud fruitfulness.
Factors controlling inflorescence primordia formation of grapevine: their role in latent bud fruitfulness?
On that winter day, 35-yearold Platt was a latent bud
Unless new growth can emerge from below ground, latent buds
(some plants have the capacity, many others do not) the plant will die.
And if we do it with care, it may sprout again from some of the latent buds
In either case, new trunks will need to be developed, and this will require retraining from shoots that originate from uninjured portions of the vine near the graft union (assuming there are live, latent buds in the graft region of the scion).
2 For injured vines with live, latent buds in the graft region of the scion, bring up as many as five or six shoots as possible renewal trunks.
This process encourages the plant to make new growth elsewhere when the flow of sap is diverted to latent buds
concealed beneath the bark.
Give them a little nitrogen (fish emulsion) in the fall; that's when strawberries develop latent buds
for the following spring.
You may save the plant by pruning it right back to encourage latent buds
to sprout at ground level.
