Ọrụ nkeAsịd IAA nke nwere 3-indole acetic

A na-eji ya eme ihe dị ka ihe na-akpali uto osisi na ihe nyocha. IAA 3-indole acetic acid na ihe ndị ọzọ dị ka 3-indoleacetaldehyde, IAA 3-indole acetic acid na ascorbic acid dị n'okike n'okike. Ihe na-ebute 3-indoleacetic acid maka biosynthesis na osisi bụ tryptophan. Ọrụ bụ isi nke auxin dị n'ịchịkwa uto osisi. Ọ bụghị naanị na ọ na-akwalite uto kamakwa ọ na-enwe mmetụta nke igbochi uto na nhazi akụkụ ahụ. Auxin abụghị naanị na ọnọdụ onwe ya n'ime mkpụrụ ndụ osisi, kamakwa ọ nwere ike ijikọ ya na macromolecules dị ndụ na ụdị auxin ndị ọzọ. E nwekwara auxin nke nwere ike ịmepụta ihe mgbagwoju anya nwere ihe pụrụ iche, dị ka indole-acetylasparagine, indole-acetyl pentose acetate na indole-acetylglucose, wdg. Nke a nwere ike ịbụ ụdị nchekwa auxin n'ime sel yana usoro iwepụ nsị nke oke auxin.

N'ọkwa sel, auxin nwere ike ịkpalite nkewa nke sel cambium; Na-akpali ịgbatị nke sel alaka ma gbochie uto nke mkpụrụ ndụ mgbọrọgwụ; Na-akwalite ọdịiche nke mkpụrụ ndụ xylem na phloem, na-eme ka mgbọrọgwụ nke ịkpụ dị mfe, ma na-achịkwa ọdịdị nke callus.

Auxin na-arụ ọrụ site na mkpụrụ ruo na ntozu oke mkpụrụ osisi ma n'ọkwa akụkụ ahụ ma n'ọkwa osisi dum. Mgbochi ọkụ uhie na-agbanwe agbanwe nke auxin n'ịchịkwa ogologo mesocotyl na mkpụrụ osisi; Mgbe indoleacetic acid na-agafe n'akụkụ ala nke alaka ahụ, geotropy nke alaka ahụ na-eme. Mgbe ebufere indoleacetic acid gaa n'akụkụ ndò nke alaka ahụ, fototropism nke alaka ahụ na-eme. Indoleacetic acid na-akpata oke nchịkwa; Ibelata ịka nká nke akwụkwọ; Auxin etinyere na akwụkwọ na-egbochi ịka nká, ebe auxin etinyere na njedebe dị nso nke oyi akwa kewara ekewa na-akwalite ịka nká. Auxin na-akwalite okooko osisi, na-akpali mmepe nke mkpụrụ osisi na-abụghị nwoke ma ọ bụ nwanyị, ma na-egbu oge ịka nká nke mkpụrụ osisi.

1. Ịmikpu

(1) N'oge okooko osisi zuru oke, a na-etinye okooko osisi ndị ahụ n'ime mmiri mmiri nke milligrams 3000 kwa lita iji mee ka tomato nwee mkpụrụ na mkpụrụ osisi, na-emepụta mkpụrụ tomato na-enweghị mkpụrụ ma na-eme ka ọnụego ntọala mkpụrụ osisi dịkwuo elu.

(2) Mgbọrọgwụ na-akwalite mgbọrọgwụ nke ihe ọkụkụ dịka apụl, piich, ube, mkpụrụ osisi citrus, mkpụrụ vaịn, kiwi, strọberị, poinsythia, carnations, chrysanthemums, rose, magnolia, rhododendrons, osisi tii, metasequoia glyptostroboides, na poplar, ma na-akpali mmepe nke mgbọrọgwụ advadvtive, na-eme ka ọsọ nke ịmụpụta ihe ọkụkụ dịkwuo ngwa ngwa. N'ozuzu, a na-eji 100-1000mg/L mee ka ntọala nke mkpụcha dị nro. Maka ụdị ndị na-adịkarị mfe ịgba mgbọrọgwụ, a na-eji obere mkpokọta. Maka ụdị ndị na-adịghị mfe ịgba mgbọrọgwụ, jiri ntakịrị mkpokọta dị elu. Oge ịgba mmiri ahụ dị ihe dị ka awa 8 ruo 24, yana nnukwu mkpokọta na obere oge ịgba mmiri.

2. Ịgba mmiri

Maka chrysanthemums (n'okpuru okirikiri ọkụ nke awa 9), ịgba mmiri nke 25-400mg/L otu ugboro nwere ike igbochi ọdịdị nke okooko osisi ma mee ka okooko ghara ịla n'iyi.
