Gibberellin ni ubwoko bwa tetracyclic diterpene hormone yibihingwa, kandi imiterere yibanze ni 20 gibberelline.Gibberellin, nkibisanzwe bikura neza kandi bikura bikura bikura imisemburo igenga imisemburo, bigira uruhare runini muguhuza imikurire yibiti, amababi, indabyo n'imbuto.
Gukoresha gibberellin
►Breba imbuto idasinziriye.
►Rkwigana imikurire y'ibihingwa.
►Control yigihe cyo kurabyo.
►Promote gutandukanya indabyo zabagabo.
►Fkubungabunga.
Impamvu zitera imbuto
Kumena imbuto ni ibintu byerekana ubusumbane bwibimera.Impamvu yibanze nuko imikurire yikibabi idashobora guhuza nimbuto zimbuto.Nyuma yubushakashatsi nincamake yintiti, ibintu bigira ingaruka kumeneka yimbuto ni: umuvuduko wa turgor ku gishishwa, umuvuduko udasanzwe wo gukura wimbuto nigishishwa, ubworoherane bwuruhu rwimbuto nuburyo imiterere yuruhu rwimbuto.Muri byo, umuvuduko wo kubyimba wa pericarp wibasiwe n’amazi n'ibiri muri gibberellin na aside abcisic;Imbaraga za mashini za pericarp zatewe nibirimo calcium hamwe nibice bigize urukuta;Kwiyongera kwa Pericarp bigira ingaruka ku ngirabuzimafatizo ya selile.Iyo umuvuduko wo kubyimba, imbaraga zumukanishi no kwaguka kwa pericarp bitaringanijwe, kuvunika imbuto bibaho.
Mugihe cyimvura, amazi menshi azongera umuvuduko wo kubyimba igishishwa, bikavamo imbuto.Mu mezi yumye nimvura, imbuto zikura vuba kurusha igishishwa.Igihe cy'imvura nikigera, ibimera byinjiza vuba amazi nintungamubiri.Ubusumbane bwikura ryikura hagati yimbuto na pericarp no kwiyongera k'umuvuduko ukabije wa pericarp biganisha ku mbuto.Gutera gaze ku mbuto z’ibimera kugirango uhuze uburyo bwumuvuduko wigishishwa nigishishwa birashobora kwirinda imbuto.
Kugeza ubu, inyandiko zimwe na zimwe zerekana inyandiko zerekana ko ubu bwoko bwa surfactant bugira ingaruka nke zoguhuza kugenzura imikurire ya gibberellin.Gushimangira buhumyi ingaruka zo guhuza inyongeramusaruro bizamura ibiciro byabahinzi.Kubwibyo, turasaba ko guhuza gushyira mu gaciro kugenzura imikurire ninyongeramusaruro bigomba guhuzwa mubuhanga ukurikije ibiranga ibikenerwa n'imboga n'imbuto mubyiciro bitandukanye byo gukura.
Benefit
♦Gukora firime kumababi cyangwa imbuto birashobora kugabanya isukwa ryamazi yimvura kubice byingenzi nkibigenga imikurire hamwe na fungicide, irinde gukoreshwa inshuro nyinshi no kugabanya ibiciro.
♦Shiraho izuba ririnda izuba hejuru yikibabi no hejuru yimbuto, ugabanye neza ibyangijwe na ultraviolet nizuba munsi yizuba ryinshi, kandi ugire uruhare mugufunga amazi no kurwanya transpiration.
♦Kuringaniza sisitemu yo kwaguka hagati yimbuto nigishishwa kugirango wirinde gucika.
♦Nyuma yo gutera imiti igabanya imikurire kugirango irusheho kurangi imbuto, irashobora guterwa kugirango yongere igihe cyo gutanga imbuto.
♦Ufatanije nubuyobozi bukura, butanga garanti yimbuto n'imboga mubyiciro bitandukanye byo gukura.
