Brown dzimbiri la tirigu (Puccinia recondita)

Description:

Brown dzimbiri la tirigu (Puccinia recondita) ndi mafangasi omwe amawononga tirigu komanso mbewu zina. Bowa ndi tizilombo tambiri tomwe timakhala ndipo timakhala ndi moyo wathunthu ndi mitundu isanu ya sporulation. Mu gawo la zomera, bowa amatha kukhalapo monga aeciospores, dikaryotic mycelium, urediniospores, ndi teliospores. Teleito- ndi uredospores amasinthidwa mwapadera kuti azizizira. M'chaka, amamera ndikupanga basidium yokhala ndi ma basidiospores anayi omwe amawononga gulu lapakati - hazel kapena cornflower. Spermatogonia imakula pamasamba a gulu lapakati, ndipo pambuyo pa feteleza, ma aetsiospores amapangidwa omwe amawononga tirigu mwachindunji.

Kufalitsa:

Bowawa wafalikira kulikonse komwe amalima tirigu. Choncho, palibe dziko limene silingathe kuwononga mbewu zambiri. Popeza kumpoto ndi ku Siberia, spores sizimakumana ndi chilala ndi kutentha kwa chilimwe, zidzapulumuka bwino, ndipo mwayi wa matenda a mbewu ukuwonjezeka kwambiri. Panthawi imodzimodziyo, dzimbiri zofiirira za tirigu zimakhudza mbewu zonse zachisanu ndi masika, komanso mitundu ina ya chimanga - bonfire, wheatgrass, wheatgrass, fescue, bluegrass.

The bowa overwinters makamaka mu mawonekedwe a mycelium mu masamba a dzinja tirigu ndi kuthengo dzinthu. Ndi kuoneka kwa mame ambiri ammawa, njere zimayamba kumera mochuluka. Kuchuluka kwa kukula kwa bowa kumagwera pa nthawi ya maluwa a chimanga.

Mtengo wachuma:

Dzimbiri la Brown limawononga kwambiri ulimi wambewu m'mayiko osiyanasiyana. M'dziko Lathu, madera omwe matendawa amapezeka nthawi zambiri ndi dera la Volga, dera la Central Black Earth ndi dera la North Caucasus. Kuno dzimbiri la bulauni limawononga tirigu pafupifupi chaka chilichonse. Pofuna kuthana ndi zomwe zimayambitsa matendawa m'mabizinesi aulimi, mitundu yosiyanasiyana ya tirigu ndi chimanga yomwe imalimbana ndi dzimbiri lamasamba imagwiritsidwa ntchito kwambiri.
