Zvikonzero zvekutsemuka kwemichero
Kutsemuka kwemichero chiitiko chechirimwa physiological imbalance.Chikonzero chakakosha ndechekuti kukura kwepeel hakugone kuenderana nekukura kwemuchero pulp.Mushure mekutsvakurudza uye pfupiso yevadzidzisi, izvo zvinopesvedzera zvinotungamira mukutsemuka kwemichero ndezvekuti: iyo turgor kudzvanywa pa peel, iyo isina kurongeka yekukura mwero we pulp uye peel, elasticity yeganda remichero uye chimiro cheganda remichero.Pakati pavo, kuputika kwe pericarp kwakakanganiswa nemvura uye zviri mukati megibberellin uye abscisic acid;Simba remagetsi re pericarp rakakanganiswa ne calcium content uye cell wall components;Pericarp extensibility inokanganiswa nesero madziro ekuzorodza geni.Apo kuputika kwekuputika, simba remagetsi uye kuwedzera kwepericarp kusina kuenzana, kuputika kwemichero kunoitika.
Mumwaka wekunaya kwemvura, mvura yakawandisa inowedzera kuputika kwepeel, zvichiita kuti michero iparare.Mumwedzi yakaoma uye inonaya, chibereko chinokura nokukurumidza kupfuura peel.Kana mwaka wekunaya kwemvura wasvika, zvirimwa zvinokurumidza kutora mvura nekudya.Iko kusaenzana kwekukura kwekukura pakati pemichero uye pericarp uye kuwedzera kwe pericarp kuzvimba kumanikidza kunotungamira mukutsemuka kwemichero.Kupfapfaidza gasi pamuchero wechirimwa kudzikamisa kudzvanywa system ye peel uye pulp kunogona kudzivirira michero kutsemuka.
Parizvino, mamwe mabhuku uye marekodhi ekuedza anoratidza kuti rudzi urwu rwesurfactant ine mashoma synergistic maitiro pane gibberellin kukura regulators.Kusimbisa neupofu iyo synergistic mhedzisiro yezvinowedzera zvichawedzera mutengo wevarimi.Nokudaro, isu tinokurudzira kuti kusanganiswa kunonzwisisika kwezvigadziridzo zvekukura uye zvinowedzera zvinofanira kusanganiswa nesayenzi maererano neunhu uye zvido zvemiriwo nemichero mumatanho ekukura akasiyana.
