Cowberry Exobasidium (Exobasidium vaccinii)

Hohola:

Loaʻa pinepine ʻia ka Exobasidium lingonberry (Exobasidium vaccinii) ma kahi kokoke i nā ululāʻau taiga a hiki i ka palena ʻākau o ka nahele ma ka Arctic. I ka hoʻomaka ʻana a i ka waena paha o ke kauwela, ʻo nā lau, a i kekahi manawa nā ʻōpala ʻōpio o nā lingonberries, ua deformed: ulu nā wahi maʻi o nā lau, ʻo ka ʻili o ka ʻaoʻao ma luna o nā lau e lilo i concave a lilo i ʻulaʻula. Ma ka ʻaoʻao lalo o nā lau, convex nā wahi i hoʻopilikia ʻia, keʻokeʻo hau. ʻOi aku ka mānoanoa o ka wahi deformed (3-10 mau manawa i ka hoʻohālikelike ʻana me nā lau maʻamau). I kekahi manawa ua deformed nā ʻōpala: mānoanoa, kūlou a lilo i keʻokeʻo. I kekahi manawa, pili pū nā pua. Ma lalo o ka microscope, maʻalahi ka hoʻokumu ʻana i nā loli nui i ke ʻano o ka lau lau. ʻIke ʻia ka nui o nā kelepona ma mua o ka nui maʻamau (hypertrophy), ʻoi aku ka nui ma mua o ka maʻamau. ʻAʻole ʻo Chlorophyll i loko o nā ʻāpana o nā wahi i hoʻopilikia ʻia, akā ʻike ʻia kahi puaʻa ʻulaʻula, anthocyanin, i loko o ke kohu cell. Hāʻawi ia i nā lau i hoʻopilikia ʻia i kahi ʻulaʻula.

ʻIke ʻia ka hyphae o ka haʻiki ma waena o nā ʻāpana o ka lingonberry, ʻoi aku ka nui o lākou ma kahi kokoke i ka ʻaoʻao haʻahaʻa o ka lau. E ulu ana nā hyphae mānoanoa ma waena o nā pūnana epidermal; ma luna o lākou, ma lalo o ka cuticle, ulu ka basidia ʻōpio. Wehe ʻia ka cuticle, hoʻokahe ʻia i ʻāpana, a ma kēlā me kēia basidium makua e hoʻokumu ʻia ai 2-6 spindle-shaped basidiospores. Mai lākou mai, ʻike ʻia kahi uhi keʻokeʻo e like me ka hau, ʻike ʻia ma ka ʻaoʻao lalo o ka lau i hoʻopilikia ʻia. ʻO Basidiospores, hāʻule i kahi kulu o ka wai, lilo koke i 3-5-celled. Mai nā ʻaoʻao ʻelua, e ulu ana nā spores ma kahi hypha lahilahi, mai nā wēlau o kahi conidia liʻiliʻi i hoʻopaʻa ʻia. Hiki iā lākou ke hana i nā blastospores. A i ʻole, ulu kēlā mau basidiospores e hāʻule i nā lau lingonberry ʻōpio. ʻO ka hyphae e kū mai ana i ka wā germination e komo i loko o ka stomata o nā lau i loko o ka mea kanu, a ua hana ʻia ka mycelium ma laila. Ma hope o 4-5 mau lā, ʻike ʻia nā wahi melemele ma nā lau, a ma hope o kekahi pule, he kiʻi maʻamau ka maʻi lingonberry. Hoʻokumu ʻia ʻo Basidium, hoʻokuʻu ʻia nā spores hou.

ʻO ka pōʻaiapili hoʻomohala piha o Exobasidium lingonberry (Exobasidium vaccinii) pono e emi iho ma mua o ʻelua pule. ʻO Exobasidium lingonberry (Exobasidium vaccinii) ke kumu a me ke kumu o ka hoʻopaʻapaʻa no nā hanauna he nui o ka mycologists. ʻIke kekahi poʻe ʻepekema i nā fungi exobasidial ma ke ʻano he pūʻulu primitive, e hōʻoiaʻiʻo ana i ke kuhiakau o ke kumu o nā hymenomycetes mai nā fungi parasitic; No laila, ua hōʻike ʻia kēia mau haʻani i ko lākou mau ʻōnaehana ma kahi ʻano kūʻokoʻa ma mua o nā hymenomycetes ʻē aʻe. ʻO nā mea ʻē aʻe, e like me ka mea kākau o kēia mau laina, e noʻonoʻo i nā fungi exobasidial ma ke ʻano he hui kūikawā nui o nā haʻani, ma ke ʻano he lālā ʻaoʻao o ka ulu ʻana o nā hymenomycetes primitive saprotrophic.

Description:

ʻAʻole i loaʻa ke kino hua o Exobasidium lingonberry (Exobasidium vaccinii). ʻO ka mua, 5-7 mau lā ma hope o ka maʻi, ʻike ʻia nā ʻāpana melemele-ʻulaʻula ma luna o nā lau, e ʻulaʻula ma hope o hoʻokahi pule. Noho ka wahi i kahi ʻāpana o ka lau a i ʻole ka lau holoʻokoʻa, mai luna mai i kaomi ʻia i ka lau deformed me ka hohonu o 0,2-0,3 cm a me ka nui o 0,5-0,8 cm, ʻulaʻula ʻulaʻula ( anthocyanin). Ma ka lalo o ka lau he puʻupuʻu mānoanoa, he ulu like me ka tumora 0,4-0,5 cm ka nui, me ka ʻili ʻole a me kahi uhi keʻokeʻo (basidiospores).

Pulp:

ʻO ka like:

Me nā ʻano ʻano kūikawā ʻē aʻe o Exobasidium: ma nā blueberries (Exobasidium myrtilli), cranberries, bearberries a me nā heathers ʻē aʻe.
