Mutemo weKuzvibata Kwemiti Kudzivirira Kugara: Synergistic Migumisiro ye6-BA (6-Benzylaminopurine) uye Chlormequat Chloride
Mukugadzirwa kwemazuva ano kwekurima, kudzora maitiro echirimwa kudzivirira pekugara idanho rakakosha rekutonga. 6-BA (6-Benzylaminopurine) neChlormequat Chloride ese ari maviri anowanzo shandiswa kukura kwezvirimwa zvinodzora. Vanodzora kukura kwezvirimwa kuburikidza nenzira dzakasiyana dzekuita, nekudaro vachizadzisa chinangwa chekudzivirira pekugara.
Mechanism Yekuita ye6-BA
6-BA ndeye cytokinin-mhando yechirimwa kukura regulator inosimudzira kupatsanurwa kwesero uye kurebesa, inowedzera chlorophyll zvemukati, uye inovandudza photosynthetic kunyatsoita. Munguva yekukura kwembesa, 6-BA inogona kukurudzira kukura kwemapazi eparutivi uye kuwedzera huwandu hwematiller, nekudaro ichivandudza hunhu hwechirimwa. Uyezve, 6-BA inogona kusimudzira kuramba kwechirimwa kumamiriro akashata, sekusanaya kwemvura uye kutonhora, izvo zvakakosha mukukura kwechirimwa munzvimbo dzakaoma.
Mechanism Yekuita yeChlormequat Chloride
Chlormequat Chloride chirimwa chinokura chinoramba chiripo chinoshanda nekudzivisa gibberellin synthesis mukati mechirimwa. Gibberellins ndiwo mahomoni makuru anokurudzira stem elongation mumiti. Naizvozvo, Chlormequat Chloride inogona kunyatso kudzora kukura kwakanyanya muzvirimwa, zvichikonzera zvirimwa zvidiki zvine hunde dzakakora, nokudaro zvichivandudza kuramba kwekugara. Chlormequat Chloride inogonawo kukurudzira kukura kwemidzi, kuwedzera kunwisa zvirimwa, uye kuwedzera goho.
Synergistic Mhedzisiro: Kushandisa 6-BA uye Chlormequat Chloride musanganiswa kunogona kuwana mhedzisiro iri nani mukugadzirisa chirimwa chirimwa mhando. 6-BA inosimudzira lateral branching uye tillering, ukuwo Chlormequat Chloride inodzora kukwirisa kureba kwedzinde guru. Iko kusanganiswa kunoguma kune yakawedzera compact chirimwa mhando uye makobvu madzinde, zvinobudirira kudzivirira pekugara. Iyi synergistic mhedzisiro haingonatsiridza kuramba kwekugara asiwo inokwidziridza photosynthetic kunyatsoita, kuwedzera goho.
