Gibberellinbụ ihe dị ike nke ukwuu ma na-akwalite uto osisi n'ozuzu ya.Enwere ike ịkwalite elongation cell cell, stem elongation, mgbasawanye nke akwukwo, mee ka uto na mmepe dịkwuo elu, mee ka ihe ọkụkụ na-eto eto na mbụ, na-amụba mkpụrụ ma ọ bụ melite mma;nwere ike imebi dormancy, kwalite germination;Mkpụrụ osisi;nwekwara ike ịgbanwe mmekọahụ na oke nke ụfọdụ osisi, ma mee ka ụfọdụ osisi biennial na-ama ifuru n'afọ dị ugbu a.
2. Ngwa nke gibberellin na mmepụta
(1) Kwalite uto, ntozu oke na mmụba mkpụrụ
Ọgwụgwọ nke ọtụtụ akwụkwọ nri akwụkwọ ndụ akwụkwọ ndụ na gibberellin nwere ike mee ka uto dịkwuo elu ma mụbaa mkpụrụ.A na-efesa Celery na mmiri mmiri 30 ~ 50mg / kg ihe dị ka ọkara otu ọnwa mgbe owuwe ihe ubi, mkpụrụ na-abawanye karịa 25%, ị ga na epupụta bụ hypertrophic, na ahịa bụ 5 ~ 6d n'ụtụtụ.
(2) gbajie ụra ma kwalite germination
Na strawberry griin haus aka cultivation na ọkara-facilitative cultivation, mgbe ikpuchi na na-ekpo ọkụ maka 3 ụbọchị, ya bụ, mgbe ihe karịrị 30% nke ifuru buds pụtara, fesa 5 ml nke 5 ~ 10 mg / kg gibberellin ngwọta kwa osisi, na-elekwasị anya. obi na-ahapụ, nke nwere ike ime ka elu inflorescence topụta tupu oge eruo., iji kwalite uto na mmalite ntozu oke.
(3) Na-akwalite uto mkpụrụ osisi
Ekwesịrị fesa akwụkwọ nri egusi na 2 ~ 3mg/kg nke mmiri mmiri n'ime mkpụrụ osisi na-eto eto otu ugboro n'oge mgbụsị akwụkwọ na-eto eto, nke nwere ike ịkwalite uto nke melons na-eto eto, mana agbala akwụkwọ ka ọ ghara ịba ụba nke okooko osisi nwoke.
(4) Gbatịkwuo oge nchekwa
Ịfesa mkpụrụ nke melons na mmiri mmiri 2.5 ~ 3.5mg / kg tupu owuwe ihe ubi nwere ike ịgbatị oge nchekwa.Ịfesa mkpụrụ osisi na mmiri mmiri 50 ~ 60mg / kg tupu ewee banana ahụ nwere mmetụta ụfọdụ na ịgbatị oge nchekwa mkpụrụ osisi.Jujube, longan na gibberellins ndị ọzọ nwekwara ike igbu oge ịka nká na ogologo oge nchekwa.
(5) Gbanwee oke nke nwoke na nwanyị okooko osisi iji mee ka mkpụrụ dị elu
Iji ahịrị kukumba nwanyị maka mmepụta mkpụrụ, ịgbasa 50-100 mg / kg nke mmiri mmiri mgbe mkpụrụ osisi nwere ezigbo akwụkwọ 2-6 nwere ike ime ka kukumba nwanyị ghọọ hermaphrodite, ịgbasa pollination zuru oke, ma mụbaa mkpụrụ osisi.
(6) Kwalite mmịpụta azuokokoosisi na ifuru, kwalite ọnụọgụ ozuzu nke ụdị ndị ama ama
Gibberellin nwere ike ịmalite ịmalite inine ogologo ụbọchị.Ịfesa osisi ma ọ bụ isi ihe na-eto eto na 50 ~ 500mg / kg nke gibberellin nwere ike ime karọt, kabeeji, radishes, celery, kabeeji China na ihe ọkụkụ ndị ọzọ na-eto eto 2a.Bolting n'okpuru ọnọdụ obere ụbọchị.
(7) Weghachite phytotoxicity nke homonụ ndị ọzọ kpatara
Mgbe ihe oriri na-edozi ahụ merụrụ ahụ, ọgwụgwọ na 2.5-5 mg / kg ngwọta nwere ike ịkwụsị phytotoxicity nke paclobutrasol na chlormethalin;ọgwụgwọ na 2 mg/kg ngwọta nwere ike ibelata phytotoxicity nke ethylene.Tomato na-emerụ ahụ n'ihi iji ihe mgbochi na-adaba n'ụzọ gabigara ókè, nke a ga-ewepụ ya site na 20mg/kg gibberellin.
