Mmetụta Physiological

Kwalite elongation na uto nke ị ga
Mmetụta physiological kachasị mkpa nke gibberellinic acid (gibberellin) bụ ịkwalite uto osisi, tumadi n'ihi na ọ nwere ike ịkwalite elongation cell. Nkwalite uto GA nwere njirimara ndị a:

1. Iji kwalite uto nke osisi dum, ọgwụgwọ GA nwere ike ịkwalite uto nke osisi osisi, karịsịa maka ụdị dwarf mutant, dị ka e gosiri na Figure 7-11. Otú ọ dị, GA enweghị mmetụta dị ịrịba ama na elongation nke akụkụ ndị dịpụrụ adịpụ, ebe IAA nwere mmetụta dị ukwuu na elongation nke ndị dịpụrụ adịpụ. Ihe kpatara GA na-akwalite elongation nke osisi dwarf bụ na ọdịnaya nke GA na ụdị dwarf dị ala karịa na ụdị nkịtị n'ihi nkwụsị nke njikọ GA endogenous.

2. Ịkwalite internode elongation GA tumadi na-eme na internode elongation dị ugbu a, kama ịkwalite mmụba nke ọnụ ọgụgụ ọnụ.

3. E nweghị mmetụta mgbochi nke superoptimal ịta Ọbụlagodi na ịta nke GA dị nnọọ elu, ọ ka nwere ike na-egosi kacha na-akwalite mmetụta, nke dị nnọọ iche na ọnọdụ ebe auxin na-akwalite osisi na-eto eto na kacha mma itinye uche.

4. Nzaghachi nke ụdị osisi dị iche iche na ụdị dị iche iche na GA dị nnọọ iche. Enwere ike nweta mkpụrụ dị elu site na iji GA na akwụkwọ nri (celery, letus, leek), ahịhịa, tii, ramie na ihe ọkụkụ ndị ọzọ.

Okooko ebutere ya
Ihe dị iche iche nke ifuru ifuru na ụfọdụ osisi dị elu na-emetụta ogologo ụbọchị (photoperiod) na okpomọkụ. Dị ka ihe atụ, biennials chọrọ a ụfọdụ ọnụ ọgụgụ nke ụbọchị ala okpomọkụ ọgwụgwọ (ie, vernalization) ka ifuru, ma ọ bụghị ha na-egosi rosette ibu na-enweghị bolting okooko. Ọ bụrụ na a na-etinye GA na osisi ndị a na-enweghị atụ, enwere ike ịmalite okooko na-enweghị usoro okpomọkụ dị ala, mmetụta ahụ pụtara ìhè. Na mgbakwunye, GA nwekwara ike ime ka okooko osisi nke ụfọdụ ogologo ụbọchị osisi kama ogologo ụbọchị osisi, ma GA enweghị na-akwalite mmetụta na ifuru nwa osisi dị iche iche nke obere ụbọchị osisi. Dịka ọmụmaatụ, GA nwere ike ịkwalite ifuru nke stevia, osisi ígwè na cypress na fir.

Mebie ụlọ ezumike
Ịgwọ poteto dormant na 2 ~ 3μg·g GA nwere ike ime ka ha na-eto ngwa ngwa, iji gboo mkpa nke ịkụ poteto ọtụtụ ugboro n'afọ. Maka mkpụrụ nke chọrọ ìhè na obere okpomọkụ ka germinate, dị ka letus, ụtaba, Perilla, plum na apple osisi, GA nwere ike dochie ìhè na ala okpomọkụ na-agbaji dormancy, n'ihi na GA nwere ike ime ka njikọ nke α-amylase, protease na ndị ọzọ hydrolases, na catalyze nbibi nke echekwara bekee na osisi maka ibu na mmepe nke embryo. N'ime ụlọ ọrụ na-emepụta biya, ịgwọ mkpụrụ ọka bali na-eto eto na-enweghị germination na GA nwere ike ịmalite mmepụta α-amylase, mee ka usoro saccharification dịkwuo ngwa n'oge ime ime, ma belata oriri iku ume nke germination, si otú ahụ belata ọnụ ahịa.

Kwalite ọdịiche ifuru nwoke
Nkezi nke nwoke okooko osisi mụbara mgbe GA ọgwụgwọ maka osisi na otu osisi. Osisi dioecious nwanyị, ọ bụrụ na a na-emeso ya na GA, ga-emepụtakwa okooko osisi nwoke. Mmetụta GA na nke a dị iche na nke auxin na ethylene.

Mmetụta Physiological

GA nwekwara ike iwusi mmetụta mkpokọta nke IAA ike na nri, kwalite ntọala mkpụrụ osisi na parthenocarpy nke osisi ụfọdụ, na igbu oge nke mkpụrụ osisi. Na mgbakwunye, GA nwekwara ike ịkwalite nkewa cell na ọdịiche dị iche iche, GA na-akwalite nkewa sel n'ihi mbelata nke G1 na S. Otú ọ dị, GA na-egbochi ịmepụta mgbọrọgwụ adventitial, nke dị iche na auxin.

Usoro ojiji

1. Kwalite nguzobe mkpụrụ osisi ma ọ bụ mkpụrụ na-enweghị mkpụrụ. Fesa kukumba na mmiri mmiri 50-100mg/kg otu ugboro n'oge okooko iji kwalite ntọala mkpụrụ osisi na ịbawanye mkpụrụ. Ụbọchị 7-10 mgbe okooko gasịrị, a na-efesa mkpụrụ vaịn na-esi ísì ụtọ na 200-500mg / kg nke mmiri mmiri otu ugboro iji kwalite ịmepụta mkpụrụ osisi na-enweghị nkume.

2. Kwalite uto oriri na-edozi ahụ nke celery 2 izu tupu owuwe ihe ubi, fesa akwụkwọ ahụ na 50-100mg / kg ọgwụ mmiri mmiri otu ugboro; Fesa akwụkwọ ahụ ugboro 1-2 izu 3 tupu owuwe ihe ubi iji gbasaa ị ga na akwụkwọ.

3. Tinye tubers na ngwọta 0.5-1mg / kg maka 30min tupu ịgha mkpụrụ nduku iji mebie dormancy ma kwalite germination; Iji 1mg/kg nke ọgwụ mmiri kụnye mkpụrụ tupu ịgha mkpụrụ nwere ike ịkwalite germination.

4. Mgbochi ịka nká na nke ọhụrụ na-edebe mmetụta Garlic moss na 50mg/kg ọgwụ ngwọta maka 10-30min, citrus green fruit period with 5-15mg/kg medicine solution spray fruit once, banana mgbe iwere ya na 10mg/kg ọgwụ ngwọta tinye mkpụrụ osisi, kukumba, watermelon / mg-5 mg tupu owuwe ihe ubi. nwere ike ime mmetụta na-edobe ọhụrụ.

5. Gbanwee okooko chrysanthemum vernalization ogbo na 1000mg / kg mmiri mmiri ịgba epupụta, cyclamen nwa osisi ogbo na 1-5mg / kg mmiri mmiri ịgba buds nwere ike ịkwalite okooko.

6. Iji melite mkpụrụ ntọala ọnụego nke ngwakọ osikapa mkpụrụ mmepụta, ọ na-n'ozuzu malitere na 15% isi nke nne, na-emeso ya na 25-55mg/kg mmiri ọgwụ ọgwụ maka 1-3 ugboro na njedebe nke 25% isiokwu. Jiri obere ntinye uche buru ụzọ, wee tinye uche dị elu.

Ihe ndị chọrọ nlebara anya

1. Gibberellic acid bụ obere mmiri soluble, gbarie ya na obere mmanya ma ọ bụ mmanya tupu ejiri ya, wee gbanye ya na mmiri ka ọ bụrụ ihe achọrọ.

2. Mkpụrụ osisi na-adịghị mma nke a na-emeso ya na gibberelic acid mụbara, n'ihi ya, ọ dịghị mma itinye ọgwụ na ubi ubi.
