Exobasidium lingonberry (Exobasidium vaccinii) sawir iyo sharaxaad

Cowberry Exobasidium (Exobasidium vaccinii)

Faafidda:

Exobasidium lingonberry ( Exobasidium vaccinii) ayaa inta badan laga helaa ku dhawaad ​​dhammaan kaymaha taiga ilaa xadka waqooyi ee kaynta Arctic. Bilawga ama badhtamaha xagaaga, caleemaha, iyo mararka qaarkood cawska yaryar ee lingonberries, way qallafsan yihiin: meelaha cudurka qaba ee caleemaha way koraan, dusha sare ee aagga dhinaca sare ee caleemaha ayaa noqda mid isku dhafan oo noqda midab casaan ah. Dhinaca hoose ee caleemaha, meelaha ay dhibaatadu saameysey ayaa ah kuwo isku dhafan, baraf-cad. Meesha qallafsan waxay noqotaa mid dhumuc weyn leh (3-10 jeer marka la barbardhigo caleemaha caadiga ah). Mararka qaarkood afkoda way qallafsan yihiin: way dhumuc, foorarsadaan oo noqdaan caddaan. Mararka qaarkood, ubaxyada ayaa sidoo kale saameeya. Marka la eego mikroskoob-ka, way fududahay in la sameeyo isbeddello waaweyn oo ku yimaada qaab-dhismeedka unugyada caleenta. Unugyadu waxay si muuqata uga weyn yihiin cabbirrada caadiga ah (hypertrophy), way ka weyn yihiin kuwa caadiga ah. Chlorophyll ayaa ka maqan unugyada meelaha ay dhibaatadu saameysey, laakiin midab cas, anthocyanin, ayaa ka muuqda dheecaanka gacanta. Waxay siinaysaa caleemaha saameeya midab cas.

Hyphae ee fangaska ayaa ka muuqda inta u dhaxaysa unugyada lingonberry, waxaa jira in badan oo iyaga ka mid ah oo u dhow dusha hoose ee caleenta. Hyphae cufan ayaa ka dhex baxa unugyada epidermal; dushooda, goynta hoosteeda, badia yar ayaa ka soo baxa. Jeexitaanka waa la jeexjeexay, googooyaa loo daadiyay, iyo basidium kasta oo qaan-gaar ah 2-6 badhidiospores-qaabeeya ayaa la sameeyay. Laga soo bilaabo iyaga, dahaar cad oo jilicsan, baraf u eg, oo laga dareemi karo dhinaca hoose ee caleenta ay saamaysay, ayaa u muuqda. Basidiospores, oo ku dhaca dhibic biyo ah, isla markiiba waxay noqdaan 3-5-unugyo. Laga soo bilaabo labada daraf, xadhkaha ayaa ka koraan hypha dhuuban, oo ka soo baxa cidhifyada kuwaas oo kondiya yaryar ay ku xiran yihiin. Waxay, markooda, samayn karaan blastospores. Haddii kale, basidiospores-yadaas waxay ku soo baxaan caleemaha lingonberry ee yaryar. Hyphae-ka soo baxa inta lagu jiro biqilka ayaa ka soo gala stomata caleemaha geedka, mycelium ayaa laga sameeyay halkaas. 4-5 maalmood ka dib, dhibco huruud ah ayaa ka muuqda caleemaha, iyo toddobaad kale ka dib, cudurka lingonberry wuxuu leeyahay sawir caadi ah. Basidium waa la sameeyay, kudka cusub ayaa la soo daayaa.

Wareegga korriinka buuxa ee Exobasidium lingonberry (Exobasidium vaccinii) wuxuu u baahan yahay wax ka yar laba toddobaad. Exobasidium lingonberry (Exobasidium vaccinii) waa shayga iyo sababta muranka jiilal badan oo mycologists ah. Saynisyahanada qaarkood waxay u arkaan fangaska exobasidial sida koox hore, taas oo xaqiijinaysa mala-awaalka asalka hymenomycetes ee fangaska dulin; Sidaa darteed, fangaskani waxay ka muuqdaan nidaamkooda si madax-bannaan oo ka horreeya dhammaan hymenomicetes kale. Kuwa kale, sida qoraaga khadadkan, waxay tixgeliyaan fangaska exobasidial sida koox gaar ah oo fangaska ah, oo ah laan dhinac ah oo ka mid ah horumarinta saprotrophic hymenomycetes.

Description:

Jirka midhaha ee Exobasidium lingonberry (Exobasidium vaccinii) ayaa maqan. Marka hore, 5-7 maalmood ka dib caabuqa, dhibco jaale-brown ah ayaa ka soo baxa caleemaha dushooda, kuwaas oo casaan noqda toddobaad ka dib. Bartu waxay ku jirtaa qayb ka mid ah caleenta ama ku dhawaad ​​caleenta oo dhan, korka waxaa lagu riixaa caleenta qallafsan oo qoto dheer oo ah 0,2-0,3 cm iyo cabbirka 0,5-0,8 cm, casaan casaan ah (casaan). anthocyanin). Qeybta hoose ee caleenta waxaa ku yaal barar dhumuc weyn leh, korriin u eg buro 0,4-0,5 cm ah oo cabbirkeedu yahay, oogada aan sinnayn iyo dahaarka cad (basidiospores).
