I-Ultrasonic Ukubonga Nokuhluma

  • Ukwelashwa kwe-ultrasonic imbewu kuyindlela ewusizo yokuhlwanyela ukukhuthaza ukuhluma.
  • I-Sonication iyindlela ephumelelayo yokuphuza imbewu ye-dormancy nokuthuthukisa izici zokuhluma.
  • Imishini ye-Hielscher ultrasonic ingalawulwa ngokuqondile ukuze kutholakale umphumela onokwethenjelwa wembewu yokuhluma nokuhluma.

I-Ultrasonic Germination

Ukushesha Ukuhluma kanye nokuvuthwa kwembewu yizici ezibalulekile zokusungulwa ngempumelelo kwezitshalo nezitshalo. Ukwenyuka kwe-Dormancy nokuhluma kubalulekile ekukhuleni nasekukhiqizeni okuqala kwezithombo zezitshalo. I-Ultrasonication yezinhlamvu emanzini noma i-osmoticum ithuthukisa izinga lokuhluma kanye nesivinini futhi ibonise amaphesenti aphezulu okuhluma kunezimbewu ezingaphenduliwe. I-sonication emnene ivuselela amangqamuzana emifino

Ukuhlukaniswa kwegobolondo ngokukhipha ama-ultrasonically, ukuguqulwa nokwandiswa kwesayizi ye-pore yembewu kuholela emandleni amaningi okugcina amanzi nezinhlamvu kanye nokuhluma okuholela ekutheni kube nokuthuthukiswa kwamanzi. Ukuguqulwa kwe-ultrasonic endosperm, njengokudakisa kwe-starch nge-sonication, kwandisa isilinganiso se-enzyme-eshukumisa ukusabela kwe-hydrolysis ngaphakathi kwembewu. Umsebenzi okhulayo we-enzyme kanye ne-hydrolysis ishesha ukukhula nokukhula kombungu ngenxa yophiko lwe-ultrasonic.

I-Ultrasonic Priming

Ukunciphisa imbewu e-osmotica efana ne-mannitol, i-polyethylene glycol (ukungasebenzi), izixazululo zelinesi (isibonelo, i-CaCl2, I-NaCl noma i-CaSO4) (halopriming) futhi emanzini (hydropriming) angathuthukiswa kalula ngokusetshenziswa kwamagagasi e-ultrasound. I-Sonication ithuthukisa ukudluliswa okukhulu phakathi kwembewu nesisombululo esizungezile okuholela ekutheni ukwandiswa kwesisombululo (okusho amanzi, izakhi kanye nokunye) kuyo imbewu. Ukusizwa nge-Ultrasonically kuyindlela yokonga, elula futhi ephephile yokwandisa amandla okuhlunga kwe-osmotic nokuthuthukisa imbewu yokuhluma, ukusungulwa kwesithombo kanye nokukhiqizwa kwezitshalo ngaphansi kwezimo ezicindezelekile.

Ama-Ultrasonic Processors for Germination and Priming

Ukuze kuthuthukiswe ukuhluma kwembewu ngo-sonication, kudingeke ukuthi kusetshenziswe izinhlelo zokulawula ultrasonic ngokuqondile. Njengoba amagagasi e-ultrasound asetshenziselwa ukugqugquzela imisebenzi yemvelo yamangqamuzana yemifino, ukuqina kwe-sonication kufanele kulungiswe uhlobo oluthile lwembewu nokulima. Ama-ultrasonic ama-Hielscher angasetshenziselwa ama-amplitudes amancane ahambisa i-cavitation kanye / noma ukuchithwa okudingekayo ukuze kutholakale imbewu yokuhluma kahle namandla. Ukwelashwa kwembewu kungasetshenziswa ku-batch kanye nakumodi yokugeleza okuqhubekayo. I-wide range of izesekeli kuvumela ukuhlanganiswa lula ultrasound zibe izakhiwo ekhona.
Izindlela ze-ultrasonic ze-Hielscher zandisa amathuba okusebenza okuphezulu okusithombo emva kokuhlwanyela.

Amaqiniso Okufanele Ukwazi

Ukuhluma

Ukuhluma kwembewu kuchaza ukuthuthukiswa nokukhula kwesitshalo kusuka enzalweni. Inqubo yokuhluma iholela ekusungulweni kwenzalo, okubandakanya izinqubo zokuxuba umzimba kanye nokuvela kwe-radium ne-plumule. Imbewu egcwele ngokugcwele iqukethe umbungu kanye nezakhi ezifakwe engxenyeni yembewu. Ngaphansi kwezimo ezifanele, imbewu iqala ukuhluma futhi izicubu ezinama-embryonic ziyaqhubeka zikhula, zithuthukela ekuvuneni. Izici ezibaluleke kakhulu zokuhluma imbewu zimanzi, i-oxygen, izinga lokushisa nokukhanya.

Ukwelashwa Okungaphambi Kokutshala

Ukuguqulwa kwembewu yikhothi yezobuchwepheshe echaza ukwelashwa okuzuzisayo okusetshenziselwa imbewu emva kokuvuna, kodwa ngaphambi kokuhlwanyela ukuze kuthuthukiswe ukuhluma nokukhula kwesithombo. Izindlela ezehlukene ziye zasetshenziselwa ukwelashwa ngaphambi kokuhlwanyela imbewu ukwenzela ukwandisa ukuhluma nokufana kokukhula kwesithombo. Izicelo zokuhlwanyela ngaphambi kokufaka imithi zihlanganisa izindlela zokwelashwa (isib. Ukukhishwa kwe-ultrasonication, ukulimaza, ukuxubha, ukuhlahlela), ukwelashwa ngamanzi ashisayo noma abilayo, ukwelashwa okushisayo okomile, ukwelashwa kwamakhemikhali (isib. Gibberellic acid / gibberellin, sulfuric acid) noma ukwelashwa kagesi. Lezo zindlela zokwelashwa zenzelwa umgomo wokuthuthukisa imbewu enamandla. Imbewu yamandla ukuhlolwa kwekhwalithi yokuhluma kwembewu engaba khona, ukuvela kwamasimu kanye nokukwazi ukugcina imbewu ngaphansi kwezimo ezahlukene kunezimila ezijwayelekile. Imbewu yamandla ilinganiswa ngokusebenzisa imbewu yokuhlolwa ngamandla.

Ukuguqulwa kwe-Endosperm

I-endosperm iyisicubu esikhiqizwa ngaphakathi kwezinhlobo zezitshalo eziningi zezimbali emva kokukhulelwa. Lizungeza umbungu futhi linikeza ukudla okunomsoco ngesimo se-starch, nakuba ingaba namafutha namaprotheni. I-endosperm ingaba ne-enzymatically modified, okuyinto isinyathelo esibalulekile ngesikhathi ukubola kwebhali. Ngesikhathi sokulimaza i-glucanses ye-enzyme ye-beta kanye nama-endoproteases asetshenziselwa ukuguqula i-endosperm ye-starchy.
