Gulu la asayansi ochokera ku mayunivesite angapo (mzinda Fierruz Ushofruz, Farhari Asia Mohames) Emulsions ochokera ku Vernonia masamba.
"Movemo wa Botrytis Cinerea ndiye cholinga cha phytopalists chifukwa cha mbewu zosiyanasiyana zazomera ndi kupezeka kwako. Tomato ndi wotengeka ku B. Cinerea, zomwe zimapangitsa matenda a sulfur-sulfur, omwe amachititsa kuti pakhale ndalama zambiri zachuma.
Pakadali pano, njira zatsopano ndi kafukufukuyu akupitilizabe kukulitsa mwambo wodalirika, chilengedwe komanso wotsika kwambiri kuti athane ndi matenda oopsawa.
Zatsimikiziridwa kuti mbewu zimatha kupanga zinthu zotetezedwa zachilengedwe kutsutsana ndi zipsinjo zazikulu komanso zovuta zambiri, kuphatikizapo kuwuwukira kwa tizilombo toyambitsa matenda. Kukonzekera kwa botanical ndi antifungal mankhwala opangira masamba nthawi zambiri kumaphatikizapo mitundu ingapo, monga emulsions, zowongolera zomasulira (mwachitsanzo, mapiritsi) ndi ma ufa.
Zina mwazomwe zimachitika, ofufuza amakonda kuphatikizika kwa emulsion kuti athetse kusungunuka kwa biootectology kumapangitsa kuti zitheke kusintha kwa boatanical.
Nanondua ndi ukadaulo watsopano mu gawo laulimi. Njira iyi ndi yokhazikika ya thermodynamic, ili ndi kinetics yayitali, imaphatikizapo kusamutsa nanoparticles, imathandizira kusiyanasiyana ndipo ili ndi vuto lalikulu. Kuphatikiza apo, kapangidwe ka nano-emulsion kumatha kupereka bwino kwambiri, onetsetsani kuti ndi tizilombo toyambitsa matenda tomwe timakhala toogens. Kukula kwa tinthu mu nano-emulsion kumakhala kochepera 500 nm, ndipo magawidwe ogawidwa sasintha ngakhale ataphwanyidwa ndi madzi.
Vernonia Amygdalina Tinct ili ndi zinthu za antifungal, kuphatikizapo spalealene, phytol, triakontan, alykontan, Heritadan ndi Neofitaden.
Kupambana pakupanga nano-invalsion mu mankhwala opangira tizilombo kumawonjezera chidwi pakupanga kwa masamba vesi V. amygdalina ngati biofune yolimbana ndi matenda a sulfur otetezeka ndi njira zoyenera.
Pankhaniyi, asayansi omwe amagwirira ntchito zaulimi wa ku University wa Peraynia adatola masamba a Vernonia, adasamba bwino, owuma mu uvuni pa 40 maola 4.
Masamba owuma adaphwanyidwa mu ufa ndikupanga m'zigawo zosasinthika mosiyanasiyana, osasefedwa ndikubweretsa. Komabe, titangotulutsa tating'onoting'ono tomwe tinasankhidwa kukhala antifungal yogwira ntchito yopanga mawonekedwe a kapangidwe kake chifukwa cha ntchito yapamwamba yolimbana ndi imvi.
Mitundu inayi ya osagwirizana ndi alkyl alkyll polyglucoside orkecactants ndipo mtundu umodzi wamafuta umagwiritsidwa ntchito ngati zigawo zigawo pakukula kwa kapangidwe kake.
Popeza m'ntchito yapitayo, masamba a masamba a Vernonia mu Mlingo wa 400 ndi 500 mg / ml adawonetsa zochitika zapamwamba kwambiri motsutsana ndi B. Cinerea (wopanda kusiyana pakati pa milingo), popanga mapangidwe apa, m'munsi Mlingo wa 400 mg / ml adatengedwa.
Nyimbo zomwe zasankhidwa zidasonyezedwa kuti F1, F2, F3, F3, F2, F7, F7, F8, F8, F8 ingatheke, miyeso ya polyduspet, ma visnction.
Nyimbo zosankhidwa zinali pa 3500 rpm kwa mphindi 30 ndi zophimbira firiji (25 ± 2 ° C Gawo 4 kwa milungu 4.
Mayeso okhazikika komanso kukhazikika kwa mafuta kudachitika pamaziko a kulembetsa mabuku a bicticciation ndi Utumiki wa Zaulimi wa Kulima. Maonekedwe a kukhazikika kwa mawonekedwe a chilichonse kumawonedwa.
Zitsanzo zopanga zimachepetsedwa ndi madzi apamwamba muyezo wa 1:10. Kupangidwa kulikonse kuchepetsedwa kunasunthidwa pa vortex kwa 1 min. Maselo a Capillary (DTS1070) adatsukidwa ndi ethanol, kenako madzi angapo musanagwiritse ntchito.
Pafupifupi 1.2 ml ya sampleyo idalowetsedwa modekha m'chipinda cholumikizidwa ndikuyika.
Ndipo kukula kwa tinthu, ndipo kuthekera kwa dzt kotsimikizika kumatsimikizika pogwiritsa ntchito chiwonetsero cha ZANA - chida cha nano zs, ku United Nation
Kukula kwa mawonekedwe amatsitsidwa kudzera mu gulu la brownian la gawo lomwalira pogwiritsa ntchito magetsi a Duwanmic ndi PETAMER DOPLOPHOPHOPHOPHOPHOROPHORESIS. Kusanthula kunabwerezedwanso katatu kwa chitsanzo chilichonse.
Kusanthula kwa mavuto ndi zinthu zina kunachitika.
Mapangidwe asanu ndi atatu osankhidwa, mapangidwe awiri, F5 ndi F7 adalimbikira panthawi yosungirako, kukula kwakukulu kwa thermonynamic, kukula kwa tinthu), ndi -31,70 mv), otsika Kuzindikira kwa polyDuspercaty Index ndi kusamvana kotsika poyerekeza ndi malingaliro ena
Zipatso za phwetekere - zidutswa 120 - mutatsuka ndikuwuma zidamizidwa mu mankhwala osankhidwa a F5 ndi F7 ndi masitepe ophatikizika.
Kuwongolera zipatso 120 zipatso kumangoyang'ana mu madzi osabala. Ndekha 70 zipatso zina kumizidwa mu 0,5 g / l ya kenlate bowa (yogwira ntchito: 50% benomila) ndikugwiritsa ntchito ngati njira yabwino.
Zipatso zonse zokonzedwa zinali matenda a msoko wa bowa, kenako ndikuyika m'matumba apulasitiki, osindikizidwa ndi mabowo. Nthawi yosungirako (tsiku la 12), pafupipafupi komanso kuopsa kwa matendawa.
Zochita za Antifungal ku SAN pa zipatso za phwetekere zidawonetsa kuti kapangidwe ka B. Cinerea ndi Zero Morbidity ndi Kuundana, Ngakhale kuti kapangidwe kake ndi 62.5% poyerekeza ndi kuwongolera bwino.
Kutengera ndi zotsatirazi, F5 wawonetsa zochitika za Antoungal, zomwe zikutanthauza kuti zingapangitse kuti zithandizire kukulitsa biofungeyi yatsopano yolimbana ndi imvi ya imvi pa tomato. "
