Ọrụ nke gibberellins: isi homonụ maka uto osisi
Gibberellins (Gibberellins) bụ klaasị nke homonụ na-emepụta ihe ọkụkụ na-ekere òkè dị mkpa na uto na mmepe osisi. Nchọpụta nke gibberellins malitere na 1930s, na mgbe ọtụtụ afọ nyochachara, ejirila ya mee ihe na ọrụ ugbo, ịkọ ihe ọkụkụ na ihe ọkụkụ. Gịnị bụ kpọmkwem ọrụ gibberellins? N'ime edemede a, anyị ga-enyocha n'ọtụtụ akụkụ nke ọrụ gibberellin.
Na-akwalite mmụba cell cell na nkewa
Otu n'ime mmetụta kachasị ama nke gibberellins bụ na ha na-akwalite elongation na nkewa nke mkpụrụ ndụ ihe ọkụkụ. Omume a dị oké mkpa maka uto na mmepe osisi. Site na-emetụta ịdị nro nke mgbidi cell na permeability nke akpụkpọ ahụ cell, gibberellin na-eme ka mgbasawanye cell dịkwuo elu, na-ebute ngwa ngwa elongation nke osisi, akwụkwọ na mgbọrọgwụ. Gibberellins na-akpalikwa nkewa cell, nke na-enye ohere ka osisi na-amụba biomass ha ngwa ngwa n'oge uto, na-egosipụta uru uto dị ukwuu.
Mmalite nke mkpụrụ osisi na ntọhapụ dormancy
Gibberellins na-ekerekwa òkè dị mkpa na mpụta mkpụrụ. Mgbe mkpụrụ na-amịkọrọ mmiri wee malite itolite, gibberellins na-arụ ọrụ wee malite ịgbakọta na nje. Hormone a na-akwalite mmepụta nke amylase, nke na-enyere mkpụrụ ahụ aka ịkụda starch echekwara ma mee ka ọ ghọọ ike maka uto osisi. Ọrụ nke gibberellins dị oke mkpa maka ụfọdụ mkpụrụ dị mkpa ka a tọhapụ ya n'ụlọ ezumike ka ọ na-akụ, ebe ọ na-agbaji dormancy ma na-amalite usoro germination, si otú ahụ na-amụba ọnụ ọgụgụ nke mkpụrụ osisi.
Iwu nke okooko na mmepe mkpụrụ
Gibberellins nwekwara mmetụta dị ukwuu na mmepe nke ifuru na mkpụrụ osisi. N'okpuru ọnọdụ fotoperiodic akọwapụtara, gibberellins nwere ike ịkwalite ọdịiche nke nwa osisi, na-eme ka osisi na-ama ifuru na mbụ ma ọ bụ na-adịkarị. Nke a dị oke mkpa maka mmepụta ugbo, ọkachasị maka njikwa ihe ọkụkụ. Gibberellin na-ekerekwa òkè n'ịkwalite uto na mmepe nke mkpụrụ osisi. Ọ bụghị naanị na ọ na-abawanye ụba nke mkpụrụ osisi, kamakwa ọ na-eme ka ọdịdị na ọdịdị nke mkpụrụ osisi ahụ dịkwuo mma, na-eme ka ọ bụrụ ihe bara uru dị ka ihe onwunwe.
Melite nguzogide osisi
Na mgbakwunye na ịkwalite uto na mmepe, gibberellin nwekwara ike ịkwalite nguzogide nke osisi na ọnọdụ gburugburu ebe obibi ọjọọ. Mgbe osisi na-enwe nrụgide nsogbu dị ka ụkọ mmiri ozuzo, salinity na obere okpomọkụ, gibberellin nwere ike imeziwanye nguzogide site n'ịhazi ụzọ usoro metabolic nke osisi. Kpọmkwem, gibberellin nwere ike ime ka ike osisi ahụ nwee ike ịmịkọrọ na idowe mmiri site na ịhazi ọdịnaya nke ihe osmoregulatory n'ime ahụ osisi ahụ, na-enyere osisi ahụ aka ịnọgide na-eto eto n'oge nsogbu.
Ngwa na ugbo na hotikoisho
N'ihi mmetụta ya dị ịrịba ama n'usoro usoro ọmụmụ physiological, a na-eji gibberellin eme ihe n'ọtụtụ ebe n'ọrụ ugbo na ịkọ ubi ọgbara ọhụrụ. Dịka ọmụmaatụ, na mmepụta osikapa, a na-eji gibberellins amụba ọnụ ọgụgụ nke mkpụrụ osisi iji hụ na ọ bara uru n'oge ịkụ ihe. Na viticulture, a na-eji gibberellins na-agwọ ụyọkọ mkpụrụ osisi iji kwalite mmụba mkpụrụ osisi ma kwalite mkpụrụ na ịdị mma. A na-ejikwa Gibberellin na-agbatị oge okooko nke ụfọdụ osisi ịchọ mma iji mee ka ifuru na-asọ mpi n'ahịa.
Nchịkọta
Ọrụ nke gibberellins nwere ọtụtụ akụkụ ma gbasaa, site n'ịkwalite elongation cell cell na mpụta mkpụrụ ruo n'ịhazi ifuru na mmepe mkpụrụ, gibberellins na-ekere òkè dị mkpa na ọkwa niile nke uto na mmepe osisi. Site na nghota miri emi nke usoro nke gibberellins, ndị na-emepụta ugbo nwere ike iji phytohormone a mee ihe nke ọma iji kwalite uto ihe ọkụkụ ma melite arụmọrụ nke mmepụta ugbo. Ya mere, ịghọta na ịmụta ọrụ nke gibberellins dị oke mkpa maka mmepe na-adigide nke ọrụ ugbo na ubi ọgbara ọhụrụ.
