Im quite sure that thay do !

I have wiped off the trics on some pre-flowers multiple times to get a wiff of the sweet sent and im sure they've grown back .

Anyone?

[Perhaps]

In a word,
no.

[Perhaps]

Or in a few more words, test have shown no but if you truly have found a strain that does, keep it and breed with it, do some structured experiments to find out.

they actualy do in nepal they will rub the plants then they will let the resin glands grow back for a second rubbing so it probley depends on the strain

[trichomefarmer]

I don't think trichomes grow back, however they do continue to grow throughout the flowering cycle.so a plant that is rubbed earlier will have new trichomes, but they didn't come from where the old ones were removed, but rather from new growth.

well thats my reasoning anyhow.

ok everybody, I've got the science here. Anyone hear of Dr. Mahlberg. He has published abot 45 papers on cannabis trichomes. I can't post attachments yet, so if you want the papers or my notes from them you can email me ( see below) . Here's some main conclusions that may help you out.
1. The capitate stalked glandular trichome is by far the largest of the 3 trichome types, forms later in maturity of the plant.
2. The specific stages of formation (about 6-8 stages of symmetrical meoisis in various planes) are followed without exception. This suggests genetic control.
3. On the other hand, trichome density has been found to be under more environmental control. This was found by growing the same strain at sea level and around 7,000 ft elevation. Trichome density is greater at higher elevations. Similiarly, trichome density can be increased by decreasing humidity.
So what can be said from all this.
1. Genes control the development of trichomes, but environment can influence their density, and thus their production.
Other considerations about trichomes;
1. Trichomes are kind of the "holy grail" in the study of cannabidology (my own term). This is because:
A. Trichomes accumulate over 90% of the plants cannabinoids
B. The disc cells of the base of the glandular head contains high amounts of plastids. This is the site of the DXP biosynthetic pathway, which produces terpenoids. One of two molecules needed to make the first cannabinoid is a terpenoid. Studies also show high secretions of cannabinoids around disc cells in the glandular head.
C. Despite these things, Mahlberg's studies also show a negative correlation between trichome density and total cannabinoid production. This means that just because a plant is covered with trichomes doesn't mean it will be extremely potent.

It seems we are truly in a sticky mess. I hope I answered more questions than I've raised, but feel free to ask if anything's confusing.

im pretty sure that........your a fool!! why would you even touch them??? thats what i call molestation!!leave them till they get older.. then you can reap the full benifits of all jah hard work!!
peace!!

That may be sciectific but it doesn't answer the question. It doesn't mention its removal or possibility of regeneration. For the record ... They are secretions and form rather than grow. If the leaf or bract isn't damaged it may form new glands.

[josh420]

so the old ones dont grow back but new ones take there place the plant produces the trichome to protect itself against the enviroment so it would make sence that it would create more

[alGrenDh]

Wipe a leaf. Mark it in some nondamaging way. Keep a check on it for a time. Do you see them coming back?

See? You've answered your question

Let us know the results, k?
