What are glandular trichomes?

Glandular trichomes are specialized hairs found on the surface of about 30% of all vascular plants and are responsible for a significant portion of a plant’s secondary chemistry.

Can seedlings have trichomes?

Simple unicellular trichomes: The first ones to appear, they can already be found on the surface of the cotyledons of the seedling. As the plant grows they also appear on the underside of the leaves and, at a lesser degree, on their surface.

Do trichomes transport nutrients?

Trichomes, or small hairlike or spikey outgrowths of epidermal tissue, may be present on the stem and leaves, and aid in defense against herbivores. Xylem tissue transports water and nutrients from the roots to different parts of the plant, and also plays a role in structural support in the stem.

Why do tomatoes have trichomes?

Have you ever wondered why tomato plants have so many little hairs on the stems and leaves? They are kind of neat to look at, but they actually serve a purpose too. The tiny hair-like structures are called trichomes, and they are there to help protect the plant from weather and herbivorous insect invasion.

Do Autoflower trichomes turn amber?

Under magnification, trichomes take on the appearance of mushrooms made from crystal clear blown glass. As the plant nears harvest time, their transparent appearance will grow cloudy and if left for longer they will turn amber.

What do trichomes prevent animals from doing?

Unlike animal hair, though, trichomes are often living cells. In many cases, trichomes protect plants from herbivorous insects that may want to feed on them. And in some cases, if the trichomes are especially stiff or irritating, they may protect a plant from larger herbivores.

What do trichomes look like when ready to harvest?

Trichomes are small crystalline mushroom-shaped bumps covering the buds. When trichomes are clear and translucent, then it indicates it’s too early to harvest. When your plant has trichomes with half clear color, then it’s time to harvest, and the buds are at its best stage with better potency.

Why are plant leaves hairy?

Trichomes can be insulating by keeping frost away from leaf cells. They can help reduce evaporation by protecting the plant from wind and heat. In many cases, trichomes protect plants from herbivorous insects that may want to feed on them.

Why are tomato plant leaves curling?

High winds, blowing dust and low humidity can damage the leaves and stems on tomato plants. Heat and low moisture can cause the edges of the tomato leaves to die back, then twist and curl. This is a self- defense response, where leaves and leaflets curl slightly to prevent further water loss (Fig. 6).
