Te tūranga oWaikawa acetic 3-indole IAA
Whakamahia hei whakaoho tipu tipu me te matū tātari. Kei te taiao te waikawa acetic IAA 3-indole me ētahi atu matū auxin pērā i te 3-indoleacetaldehyde, te waikawa acetic IAA 3-indole me te waikawa ascorbic. Ko te matū o te waikawa 3-indoleacetic mō te hanga koiora i roto i ngā tipu ko te tryptophan. Ko te mahi matua o te auxin kei te whakahaere i te tipu o ngā tipu. Ehara i te mea ka whakatairanga noa i te tipu engari he pānga anō hoki ki te aukati i te tipu me te hanganga okana. Ehara i te mea kei roto noa te auxin i te āhua kore utu i roto i ngā pūtau tipu, engari ka taea hoki te herea kaha ki ngā macromolecules koiora me ētahi atu momo auxin. Kei reira anō hoki ngā auxin ka taea te hanga matatini me ngā matū motuhake, pērā i te indole-acetyllasparagine, te indole-acetyl pentose acetate me te indole-acetylglucose, me ētahi atu. He momo rokiroki auxin pea tēnei i roto i ngā pūtau, ā, he tikanga tango paitini hoki hei whakakore i te paitini o te auxin nui rawa.
I te taumata pūtau, ka taea e te auxin te whakaoho i te wehenga o ngā pūtau cambium; te whakaoho i te roa o ngā pūtau peka me te aukati i te tipu o ngā pūtau pakiaka; te whakatairanga i te rerekētanga o ngā pūtau xylem me te phloem, te whakahaere i te pakiaka o ngā tapahi, me te whakahaere i te morphogenesis o te callus.
He mahi tā te auxin mai i te whakatipuranga ki te pakari o te hua i ngā taumata okana me te tipu katoa. Ka taea te whakakore i te aukati rama whero o te auxin ki te whakahaere i te roa o te mesocotyl i roto i ngā tipu; Ina whakawhiti te waikawa indoleacetic ki te taha o raro o te manga, ka puta te geotropy o te manga. Ina whakawhitia te waikawa indoleacetic ki te taha atarangi o te manga, ka puta te phototropism o te manga. Ka puta te mana o runga o te waikawa indoleacetic; Ka whakaroa i te koroheketanga o te rau; Ka aukati te auxin i pania ki ngā rau i te maturuturunga, ko te auxin i pania ki te pito tata o te paparanga wehe ka whakatairanga i te maturuturunga. Ka whakatairanga te auxin i te pua, ka whakaoho i te whanaketanga o ngā hua kotahi-ira, ā, ka whakaroa i te maoa o te hua.
Te tikanga whakamahi oWaikawa acetic 3-indole IAA
1. Te ruku
(1) I te wā e puāwai ana ngā tōmato, ka rumakina ngā putiputi ki roto i te wairewa o te 3000 mirikaramu ia rita hei whakaoho i te hua parthenogenic me te whakatakoto hua o ngā tōmato, ka puta he hua tōmato kore purapura, ā, ka tere ake te whakatakoto hua.
(2) Mā te rumaki pakiaka ka whai pakiaka ngā hua pēnei i te aporo, te pītiti, te pea, te hua citrus, te karepe, te kiwi, te rōpere, te poinsythia, te carnation, te chrysanthemum, te rōhi, te magnolia, te rhododendron, te tī, te metasequoia glyptostroboides, me te poplar, ā, ka whakaoho i te hanganga o ngā pakiaka tautoko, ka tere ake te tere o te whakaputa uri. I te nuinga o te wā, ka whakamahia te 100-1000mg/L hei rumaki i te pūtake o ngā tapahi. Mō ngā momo e ngāwari ana ki te rumaki, ka whakamahia he kukū iti ake. Mō ngā momo kāore e ngāwari ki te rumaki, whakamahia he kukū teitei ake. Ko te wā rumaki he tata ki te 8 ki te 24 hāora, he kukū teitei, he wā rumaki poto hoki.
2. Te rehu
Mō ngā kārihimā (i raro i te huringa mārama 9-hāora), ko te rehu kotahi ki te wairewa o te 25-400mg/L ka ārai i te putanga mai o ngā puku putiputi me te whakaroa i te pua.
