Thepa ea Physicochemical le Mefuta ea Tlhahiso ea Gibberellic Acid GA3

Gibberellic Acid (GA3) ke hormone ea semela e khothalletsang ho hōla ha kutu le makhasi, ho fokotsa ho ntšoa ha li-cotton buds le li-boll, ho eketsa chai ea harese, le ho ntlafatsa litekanyetso tsa litholoana bakeng sa lijalo tse kang morara, li-citrus le lipere.

I. Physicochemical Properties of Gibberellic Acid:

Tlhaloso: White crystalline powder. Sebaka se qhibilihang: 233-235 ° C (ho bola). E qhibilihang ka joala, acetone, ethyl acetate, sodium bicarbonate solution, le pH 6.2 phosphate buffer; e qhibilihang hanyenyane metsing le diethyl ether. Litharollo tsa metsi li na le asiti ebile ha li tsitsitse (li atisa ho lahleheloa ke ts'ebetso). E senyeha habonolo ka pel'a alkalis. E fetoha bofubelu bo tebileng ha e kopana le sulfuric acid.

Mokhoa oa Tlhahiso: Gibberellic Acid e ka hlahisoa ka bongata ka ho belisoa. *Gibberella fujikuroi* (mofuta oa *Fusarium* fungus) e lengoa ka mokhoa o nang le lehlaka la koro, sucrose, le matsoai a sa tloaelehang; fungus e hlahisa Gibberellic Acid joalo ka sehlahisoa sa metabolic. Moro o belisoa o etsoa ka mokelikeli le mahloriso ho hlahisa likristale tsa Gibberellic Acid.

Lisebelisoa: Gibberellic Acid (GA3) ke hormone ea ho hōla ha limela e khothalletsang ho hōla ha limela le makhasi, ho etsa hore ho be le bolting le ho thunya pele ho nako, ho susumelletsa ho mela ha peo, li-tubers le li-tubers tsa metso, 'me ho khothalletsa ho hōla ha litholoana, ho eketsa litekanyetso tsa litholoana kapa ho etsa hore ho be le litholoana tse se nang peo. E eketsa chai bakeng sa lijalo tse kang litapole, tamati, raese, koro, k’hothone, linaoa tsa soya, lierekisi, koae le lifate tsa litholoana.

Leha ho le joalo, tšebeliso e feteletseng ea Gibberellic Acid (GA3) e ka etsa hore limela li be le letlobo le tšesaane, le mosehla-e leng boemo bo tsejoang e le chlorosis kapa "leggy" kgolo - e hlileng e ka fokotsang chai. Gibberellic Acid (GA3) e boetse e sebelisoa tlhahisong ea 'mela ho tsoa harese. E boetse e khothalletsa nts'etsopele ea likokoanyana.

Litlhokomelo tsa tlhahiso le ho sebetsana:
1. Gibberellic Acid (GA3) ha e qhibilihe ka metsing;
2. E sekametse ho hydrolysis;
3. Ha e na mocheso; ho khothalletsoa ho boloka mocheso o tlase;
4. E na le nako e khutšoanyane ea bophelo;
5. E na le mesebetsi e mengata, empa lijalo tse fapaneng li bonts'a maemo a fapaneng a kutlo, a hlokang mekhoa e ikhethileng ea kalafo;
6. Lihlahisoa tsa phofo li fana ka botsitso bo botle. II. Lihlahisoa tsa Gibberellic Acid:
Powders, soluble powders, effervescent formulations, matlapa a qhibilihang, li-pastes; litharollo tse nang le metsi, li-concentrates tse emulsifiable, metsoako ea metsi.
