Exobasidium lingonberry (Exobasidium vaccinii) yees duab thiab piav qhia

Cowberry Exobasidium (Exobasidium Vaccinii)

Kis:

Exobasidium lingonberry (Exobasidium vaccinii) feem ntau pom nyob rau hauv yuav luag tag nrho cov hav zoov taiga mus rau sab qaum teb ciam teb ntawm hav zoov nyob rau hauv Arctic. Thaum pib lossis nruab nrab ntawm lub caij ntuj sov, cov nplooj, thiab qee zaum cov tub ntxhais hluas stalks ntawm lingonberries, yog deformed: cov kab mob ntawm nplooj loj hlob, qhov chaw ntawm thaj chaw ntawm sab sauv ntawm nplooj yuav concave thiab ua xim liab. Nyob rau hauv qab ntawm nplooj, cov cheeb tsam cuam tshuam yog convex, snow-dawb. Qhov chaw deformed ua thicker (3-10 zaug hauv kev sib piv nrog cov nplooj qub). Qee zaum cov stems yog deformed: lawv thicken, khoov thiab tig dawb. Qee zaus, paj kuj raug cuam tshuam. Nyob rau hauv lub microscope, nws yog ib qho yooj yim los tsim kom muaj kev hloov loj hauv cov qauv ntawm cov ntaub so ntswg. Cells yog pom tau tias loj dua li qhov ntau thiab tsawg (hypertrophy), lawv loj dua li qub. Chlorophyll tsis muaj nyob rau hauv cov hlwb ntawm cov cheeb tsam cuam tshuam, tab sis cov xim liab, anthocyanin, tshwm nyob rau hauv cell kua. Nws muab cov nplooj cuam tshuam xim liab.

Lub hyphae ntawm fungus yog pom nyob nruab nrab ntawm lub hlwb ntawm lingonberry, muaj ntau ntawm lawv nyob ze rau hauv qab ntawm nplooj. Thicker hyphae loj hlob ntawm cov hlwb epidermal; ntawm lawv, nyob rau hauv lub cuticle, cov tub ntxhais hluas basidia tsim. Lub cuticle yog torn, los ntawm daim, thiab nyob rau hauv txhua tus paub tab basidium 2-6 spindle-shaped basidiospores yog tsim. Los ntawm lawv, ib tug maj, Frost-zoo li dawb txheej, pom nyob rau hauv lub underside ntawm nplooj, tshwm. Basidiospores, poob rau hauv dej, sai sai ua 3-5-celled. Los ntawm ob qho tag nrho, cov spores loj hlob raws li nyias hypha, los ntawm qhov kawg ntawm cov me me conidia laced. Lawv tuaj yeem tsim blastospores. Txwv tsis pub, cov basidiospores germinate uas poob ntawm cov tub ntxhais hluas lingonberry nplooj. Lub hyphae uas tshwm sim thaum lub sij hawm germination nkag mus rau hauv lub stomata ntawm nplooj mus rau hauv cov nroj tsuag, thiab mycelium yog tsim muaj. Tom qab 4-5 hnub, yellowish me ntsis tshwm rau ntawm nplooj, thiab tom qab lwm lub lis piam, tus kab mob lingonberry muaj ib tug raug daim duab. Basidium yog tsim, tshiab spores raug tso tawm.

Txoj kev loj hlob tag nrho ntawm Exobasidium lingonberry (Exobasidium vaccinii) yuav tsum tau tsawg dua ob lub lis piam. Exobasidium lingonberry (Exobasidium vaccinii) yog cov khoom thiab ua rau muaj kev tsis sib haum xeeb rau ntau tiam neeg ntawm mycologists. Qee cov kws tshawb fawb pom exobasidial fungi ua ib pawg thawj coj, uas lees paub qhov kev xav ntawm lub hauv paus chiv keeb ntawm hymenomycetes los ntawm cov kab mob parasitic; Yog li ntawd, cov kab mob no tau sawv cev rau hauv lawv cov kab ke hauv kev ywj pheej ua ntej ntawm tag nrho lwm cov hymenomycetes. Lwm tus, zoo li tus sau cov kab no, xav txog exobasidial fungi ua ib pawg tshwj xeeb ntawm cov fungi, ua ib ceg ntawm kev loj hlob ntawm saprotrophic primitive hymenomycetes.

hauj lwm:

Lub cev txiv hmab txiv ntoo ntawm Exobasidium lingonberry (Exobasidium vaccinii) tsis tuaj. Ua ntej, 5-7 hnub tom qab kis kab mob, cov xim daj-xim av tshwm rau saum nplooj, uas tig liab tom qab ib lub lim tiam. Qhov chaw nyob ib feem ntawm nplooj los yog yuav luag tag nrho nplooj, los ntawm saum toj no nws yog nias rau hauv cov nplooj deformed nrog ib tug tob ntawm 0,2-0,3 cm thiab ib tug loj ntawm 0,5-0,8 cm, crimson liab ( anthocyanin). Nyob rau hauv qab ntawm nplooj muaj ib tug thickened bulge, ib tug qog zoo li loj hlob 0,4-0,5 cm nyob rau hauv loj, nrog ib tug tsis sib xws nto thiab nrog ib tug dawb txheej (basidiospores).

Pulp:

Qhov zoo sib xws:

Nrog rau lwm hom tshwj xeeb ntawm Exobasidium: ntawm blueberries (Exobasidium myrtilli), cranberries, bearberries thiab lwm yam heathers.
