ʻO ka ʻōpala ʻulaʻula o ka palaoa (Puccinia recondita)

Description:

ʻO ka ʻōpala ʻulaʻula o ka palaoa (Puccinia recondita) he haʻupuʻu parasitic e hoʻopilikia mua i ka palaoa a me nā cereals ʻē aʻe. ʻO kēia haʻuki he ʻelua mea hoʻokipa a loaʻa iā ia kahi pōʻai ola piha me nā ʻano ʻelima o ka sporulation. I ka wā kanu, hiki ke noho ka haʻuki ma ke ʻano he aeciospores, dikaryotic mycelium, urediniospores, a me teliospores. Hoʻololi kūikawā ʻia ʻo Teleito- a me uredospores no ka hoʻoilo. I ka pūnāwai, ulu lākou a hana i basidium me nā basidiospores ʻehā e hoʻopōʻino i ka pūʻali waena - hazel a i ʻole cornflower. Hoʻokumu ʻia ka Spermatogonia ma nā lau o ka pūʻali waena, a ma hope o ka cross-fertilization, hoʻokumu ʻia nā aetsiospores e hoʻopili pololei i ka palaoa.

Hohola:

Laha loa keia hamu ma na wahi a pau e ulu ai ka palaoa. No laila, ʻaʻohe ʻāina i pale ʻole i ka luku nui ʻia o nā mea kanu. No ka mea ma ka ʻāina ʻākau a ma Siberia, ʻaʻole ʻike ʻia nā spores i ka maloʻo o ke kauwela a me ka wela, e ola maikaʻi lākou, a piʻi nui ka nui o ka maʻi hua. I ka manawa like, pili ka ʻeleʻele ʻeleʻele o ka palaoa i ka hoʻoilo a me nā mea kanu puna, a me nā ʻano cereals ʻē aʻe - ahi ahi, mauʻu palaoa, mauʻu palaoa, fescue, bluegrass.

Hoʻomaka ka haʻuki ma ke ʻano o ka mycelium i nā lau o ka palaoa hoʻoilo a me nā cereals hihiu. Me ka ʻike ʻana o ka hau kakahiaka nui, hoʻomaka nā spores e ulu nui. Hāʻule ka piko o ka ulu ʻana o ka haʻiki i ka wā o ka pua o nā cereals.

Waiwai waiwai:

Hoʻopilikia nui ka ʻōpala ʻulaʻula i ka hana ʻai ma nā ʻāina like ʻole. Ma ko mākou ʻāina, ʻo nā ʻāina kahi i loaʻa pinepine ai kēia maʻi ʻo ia ka ʻāina ʻo Volga, ka ʻāina ʻo Central Black Earth a me ka ʻāina o ka North Caucasus. Maʻaneʻi e hoʻopilikia i ka palaoa ʻeleʻele i kēlā me kēia makahiki. No ka hakakā maikaʻi ʻana i ka mea kumu o kēia maʻi i loko o nā ʻoihana mahiʻai, hoʻohana nui ʻia nā ʻano ʻano o ka palaoa a me nā cereals i kū i ka lau lau.
