Phello ea 'mele
Khothalletsa ho hola le ho hola ha stems
Phello ea bohlokoa ka ho fetisisa ea fisioloji ea gibberellinic acid (gibberellin) ke ho khothaletsa kholo ea semela, haholo hobane e ka khothaletsa ho lelefatsa lisele. Kholiso ea kholo ea GA e na le litšobotsi tse latelang:
1. Ho khothalletsa ho hōla ha limela tse feletseng, phekolo ea GA e ka khothalletsa kholo ea limela, haholo-holo bakeng sa mefuta e sa tšoaneng ea mefuta e sa tšoaneng, joalokaha ho bontšitsoe setšoantšong sa 7-11. Leha ho le joalo, GA ha ea ka ea e-ba le phello e kholo ho atoloseng ha likarolo tsa kutu tse arohaneng, athe IAA e bile le phello e kholo ho atoloseng ha likarolo tse ikhethileng tsa kutu. Lebaka leo ka lona GA e khothalletsang katoloso ea limela tse nyane ke hore litaba tsa GA mefuteng e menyenyane li tlase ho feta tsa mefuta e tloaelehileng ka lebaka la tšitiso ea motsoako oa endogenous GA.
2. Ho khothalletsa internode elongation GA haholo-holo e sebetsa ka bolelele ba internode e teng, ho e-na le ho khothalletsa ho eketseha ha palo ea li-node.
3. Ha ho na inhibition effect of superoptimal concentration Le hoja mahloriso a GA a phahame haholo, a ntse a ka bontša phello e kholo ea ho khothalletsa, e fapaneng haholo le boemo boo auxin e khothalletsang kholo ea limela ka mahloriso a nepahetseng.
4. Karabelo ea mefuta e fapaneng ea limela le mefuta e fapaneng ho GA e fapane haholo. Kotulo e phahameng e ka fumanoa ka ho sebelisa GA ka meroho (celery, lettuce, leek), joang, tee, ramie le lijalo tse ling.
Lipalesa tse susumetsoang
Phapang ea lipalesa limela tse ling tse phahameng li susumetsoa ke bolelele ba letsatsi (photoperiod) le mocheso. Mohlala, li-biennials li hloka palo e itseng ea matsatsi a kalafo e tlase ea mocheso (ke hore, vernalization) ho thunya, ho seng joalo li bonts'a kholo ea rosette ntle le ho thunya ha lipalesa. Haeba GA e sebelisoa ho limela tsena tse sa tsitsang, lipalesa li ka susumetsoa ntle le ts'ebetso e tlaase ea mocheso, 'me phello e totobetse haholo. Ho feta moo, GA e ka boela ea etsa hore limela tse ling tsa matsatsi a malelele li thunye ho e-na le limela tsa letsatsi le lelelele, empa GA ha e na phello e khothalletsang phapang ea lipalesa tsa limela tsa matsatsi a khutšoanyane. Ka mohlala, GA e ka khothalletsa ho thunya ha stevia, sefate sa tšepe le limela tsa cypress le fir.
Phomolo ea boroko
Ho phekola litapole tse robetseng ka 2 ~ 3μg·g GA ho ka etsa hore li mele ka potlako, e le ho finyella litlhoko tsa ho lema litapole ka makhetlo a mangata ka selemo. Bakeng sa peo e hlokang mocheso o bobebe le o tlase ho mela, joalo ka lettuce, koae, Perilla, plum le peo ea apole, GA e ka nka sebaka sa khanya le mocheso o tlase ho senya dormancy, hobane GA e ka etsa hore ho be le α-amylase, protease le hydrolases tse ling, 'me ea baka ho senyeha ha lintho tse bolokiloeng peo bakeng sa kholo le nts'etsopele ea embryo. Lefapheng la tlhahiso ea biri, ho phekola peō ea harese e budding ntle le ho mela ka GA ho ka etsa hore tlhahiso ea α-amylase, e potlakise ts'ebetso ea saccharification nakong ea ho noa, le ho fokotsa tšebeliso ea phefumoloho ea ho mela, kahoo ho fokotsa litšenyehelo.
Khothalletsa phapang ea lipalesa tsa banna
Karolo ea lipalesa tsa banna e ile ea eketseha ka mor'a phekolo ea GA bakeng sa limela tse nang le semela se le seng. Limela tse tšehali tsa dioecious, haeba li tšoaroa ka GA, li tla boela li hlahise lipalesa tsa banna. Phello ea GA tabeng ena e fapane le ea auxin le ethylene.
Phello ea 'mele
GA e ka boela ea matlafatsa tšusumetso ea IAA ho limatlafatsi, ea khothalletsa boemo ba litholoana le parthenocarpy ea limela tse ling, le ho liehisa ho mela ha makhasi. Ho feta moo, GA e ka boela ea khothalletsa karohano ea lisele le ho arohana, 'me GA e khothalletsa karohano ea lisele ka lebaka la ho khutsufatsoa ha mekhahlelo ea G1 le S. Leha ho le joalo, GA e thibela ho thehoa ha metso ea adventitial, e fapaneng le ea auxin.
Mokhoa oa tšebeliso
1. Khothalletsa ho thehoa ha litholoana kapa litholoana tse se nang peo. Fafatsa likomkomere ka mokelikeli oa 50-100mg/kg hang nakong ea lipalesa ho khothaletsa boemo ba litholoana le ho eketsa chai. Matsatsi a 7-10 ka mor'a ho thunya, morara o nkhang hamonate oa rosa o ne o fafatsoa ka 200-500mg/kg ea mokelikeli hang ho khothalletsa ho thehoa ha litholoana tse se nang majoe.
2. Khothalletsa kholiso ea phepo ea celery libeke tse 2 pele ho kotuloa, fafatsa makhasi ka moriana oa metsi oa 50-100mg/kg hang; Fafatsa makhasi makhetlo a 1-2 libeke tse 3 pele ho kotuloa ho holisa kutu le makhasi.
3. Soak li-tubers ka tharollo ea 0.5-1mg/kg bakeng sa 30min pele u jala litapole ho senya dormancy le ho khothalletsa ho mela; Ho inela peo ka 1mg/kg ya moriana o metsi pele o jala ho ka kgothalletsa ho mela.
4. Anti-botsofali le phello e ncha ea ho boloka konofolo e nang le 50mg/kg tharollo ea moriana bakeng sa 10-30min, nako ea litholoana tse tala tsa lamunu e nang le 5-15mg/kg ea moriana o fafatsa litholoana hang, banana ka mor'a ho kotuloa ka 10mg/kg tharollo ea moriana, inela litholoana, likomkomere, lehapu le lehapu pele ho kotuloa ka thipa ea 50 mg / 50 mg. phello ea ho boloka bocha.
5. Lokisa palesa ea chrysanthemum vernalization sethaleng ka 1000mg/kg makhasi a mokelikeli oa spray, sethala sa cyclamen bud se nang le 1-5mg/kg li-spray tsa mokelikeli li ka khothaletsa lipalesa.
6. Ho ntlafatsa sekhahla sa ho beha peō ea tlhahiso ea peō e nyalisitsoeng ea raese, hangata e qala ho 15% ea hlooho ea 'm'e, 'me e phekoloa ka moriana oa metsi oa 25-55mg/kg makhetlo a 1-3 qetellong ea 25%. Sebelisa mahloriso a tlaase pele, ka mor'a moo u sebelise khatello e phahameng.
Litaba tse hlokang tlhokomelo
1. Asiti ea Gibberellic ha e qhibilihe ka metsing, e qhibiliha ka tekanyo e nyenyane ea joala kapa joala pele e sebelisoa, ebe e hlapolla ka metsi ho ea mahloriso a hlokahalang.
2. Peo e nyopa ea lijalo e tšoaroang ka gibberellic acid e ile ea eketseha, kahoo ha ea lokela ho sebelisa meriana masimong a ho lema.
