Abstract
Plod breskve uvrščamo med koščičaste plodove. Sestavljen je iz semena in perikarpa. Perikarp pa je zgrajen iz endokarpa, mezokarpa, eksokarpa. Epiderm je primarno krovno tkivo. Trihomi so diferenciacije epiderma. Njihova funkcija je izmenjava plinov z okolico, uravnavanje vodne bilance ter varovanje pred mehanskimi poškodbami. Epiderm breskve se pojavlja v dveh oblikah (gol plod in plod pokrit s trihomi). Celične stene epiderma so pogosto zadebeljene. V njih in nad njimi se nalaga kutin. Plasti, ki se naloži na zunanjo stran celične stene, pravimo kutikula. Trihomi pri breskvi so mrtvi, enocelični in imajo debele celične stene ter ozek lumen. Proces nastanka trihomov pri breskvi na našem območju traja od druge polovice marca pa vse do prve polovice junija. Gostota in dolžina trihomov se od sorte do sorte zelo razlikuje. Lipid transfer proteini (LTP) so tujki, ki sodelujejo pri razvoju alergičnih reakcij. LTP, ki se pojavlja predvsem v eksokarpu plodov breskve, se imenuje Pru p 3. S pomočjo glutationa lahko zmanjšamo riziko pojava alergijskih reakcij na breskev in zmanjšamo tudi proizvajanje IgE, ki se pojavi ob povečanju koncentracije LTP v celici.

Title:Peach trichomes and allergies
Abstract:
The peach fruit is classified as stone fruits. It is composed of seeds and pericarp. Pericarp is built from an endocarp, a mesocarp and an exocarp. Epidermis is the primary umbilical tissue. Trihomes are differentiations of the epidermis. Their function is to exchange gases with the surroundings, to regulate the water balance and to protect against mechanical damage. The peach epidermis occurs in two forms (the naked fruit and the fruit covered with trichoms). The cell walls of the epidermis are often thickened. Wax cutin is loaded in and over them. The layers that are loaded on the outside of the cell wall are called a cuticula. Peach trihomas are dead, single-celled, with thick cell walls and narrow lumen. The process of trichoma formation in peach in our area lasts from the second half of March until the first half of June. The density and length of trichomes varies greatly from variety to variety. Lipid transfer proteins (LTP) are foreign. They are involved in the development of allergic reactions. LTP, which occurs mainly in the peach's exocarp, is called Pru p 3. With the help of glutathione, we can reduce the risk of allergic reactions and reduce the production of IgE, which occurs when the concentration of LTP in the cell increases.
