Dwarf Schefflera ni urugo ruzwi cyane ku isi, kandi imikurire yarwo n'iterambere byarimo kwitabwaho cyane. Imikoreshereze yubuyobozi bukura bwibimera byatumye habaho itandukaniro rigaragara, hamwe nubuvuzi bwose bwongera uburebure bwibimera ugereranije no kugenzura. Nubwo uburebure bwibimera bugenzurwa genetiki, ubushakashatsi bwerekana ko gushyira mubikorwa kugenzura imikurire yikimera bishobora kongera cyangwa kugabanya uburebure bwibimera. Uburebure bw'ibihingwa n'umubare w'amababi yavuwe hamwe na aside ya gibberellic + benzyladenine 200 mg / L niyo yari hejuru cyane, igera kuri cm 109 na 38.25. Bihuye nubushakashatsi bwabanje (SalehiSardoei et al.52) na Spathiphyllum23, kwiyongera nkuburebure bwibimera bitewe no kuvura aside ya gibberellic byagaragaye muri marigolds yabumbwe, albus alba21, daylilies22, umunsi wumunsi, agarwood na lili yamahoro.
Acide ya Gibberellic (GA) igira uruhare runini mubikorwa bitandukanye byimiterere yibimera. Zitera amacakubiri, kurambura ingirabuzimafatizo, kurambura uruti no kwiyongera 24. GA itera amacakubiri no kurambura mu kurasa apices na meristems25. Guhindura amababi harimo no kugabanya umubyimba wuruti, ingano yamababi mato, hamwe nicyatsi kibisi 26. Ubushakashatsi bwifashishije ibintu bibuza cyangwa bitera imbaraga byerekanye ko calcium ion ziva mumbere zikora nkintumwa za kabiri muri gibberellin yerekana inzira mumasaka corolla27. HA yongerera uburebure bwibimera itera synthesis yimisemburo itera urukuta rwingirabuzimafatizo, nka XET cyangwa XTH, expansins na PME28. Ibi bitera ingirabuzimafatizo kwiyongera uko urukuta rw'akagari ruruhuka kandi amazi yinjira muri selire29. Gukoresha GA7, GA3 na GA4 birashobora kongera kuramba 30,31. Acide ya Gibberellic itera kurambura uruti mu bimera bya dwarf, no mu bimera bya rosette birinda gukura kwamababi no kurambura internode32. Nyamara, mbere yicyiciro cyimyororokere, uburebure bwuruti bwiyongera kugera kuri 4-5 uburebure bwumwimerere33. Inzira ya GA biosynthesis mu bimera yavuzwe mu gishushanyo cya 9.
GA biosynthesis mu bimera n'urwego rwa endogenous bioactive GA, igishushanyo mbonera cy'ibimera (iburyo) na GA biosynthesis (ibumoso). Imyambi ni ibara ryanditse kugirango rihuze nuburyo bwa HA bwerekanwe kumuhanda wa biosynetique; imyambi itukura yerekana igabanuka rya GC bitewe nubusanzwe mu ngingo z’ibimera, naho imyambi yumukara yerekana urwego rwa GC rwiyongereye. Mu bimera byinshi, nk'umuceri na watermelon, ibirimo GA biri hejuru munsi cyangwa igice cyibabi30. Byongeye kandi, raporo zimwe zerekana ko ibinyabuzima bya bioactive GA bigabanuka uko amababi arambuye kuva shingiro34. Urwego nyarwo rwa gibberelline muribi bihe ntiruzwi.
Igenzura ryikura ryibimera naryo rigira uruhare runini mumibare nubuso bwamababi. Ibisubizo byerekanaga ko kongera ubwiyongere bwikura ryikura ryibimera byatumye ubwiyongere bugaragara bwibibabi numubare. Bivugwa ko Benzyladenine yongerera umusaruro amababi ya calla15. Ukurikije ibyavuye muri ubu bushakashatsi, uburyo bwose bwo kuvura bwateje imbere amababi n'umubare. Acide Gibberellic + benzyladenine niyo miti ivura neza kandi bivamo umubare munini nubuso bwamababi. Iyo ukura dwarf schefflera mumazu, hashobora kubaho kwiyongera kugaragara mumibare yamababi.
Ubuvuzi bwa GA3 bwongereye interode ugereranije na benzyladenine (BA) cyangwa nta kuvura imisemburo. Igisubizo kirumvikana ukurikije uruhare rwa GA mugutezimbere iterambere7. Gukura kw'ibiti nabyo byagaragaje ibisubizo bisa. Acide ya Gibberellic yongereye uburebure bwuruti ariko igabanya diameter. Ariko, gushyira hamwe kwa BA na GA3 byongereye cyane uburebure bwuruti. Ubu bwiyongere bwari hejuru ugereranije nibihingwa bivurwa na BA cyangwa bidafite imisemburo. Nubwo aside ya gibberellic na cytokinine (CK) muri rusange biteza imbere imikurire yibihingwa, rimwe na rimwe bigira ingaruka zinyuranye mubikorwa bitandukanye35. Kurugero, imikoranire mibi yagaragaye mukwiyongera kwuburebure bwa hypocotyl mubihingwa bivurwa na GA na BA36. Kurundi ruhande, BA yiyongereye cyane ingano yumuzi (Imbonerahamwe 1). Ubwiyongere bwumuzi bitewe na BA exogenous BA byagaragaye mubimera byinshi (urugero ubwoko bwa Dendrobium na Orchide) 37,38.
Imiti yose ivura imisemburo yongereye umubare wamababi mashya. Ubwiyongere busanzwe bwibibabi hamwe nuburebure bwuruti binyuze mubuvuzi bukenewe ni ubucuruzi. Umubare wamababi mashya nikimenyetso cyingenzi cyo gukura kwibimera. Gukoresha imisemburo ya exogenous ntabwo yakoreshejwe mubikorwa byubucuruzi bya Liriodendron tulipifera. Nyamara, ingaruka ziterambere ryiterambere rya GA na CK, zikoreshwa muburinganire, zishobora gutanga ubumenyi bushya mugutezimbere ubuhinzi bwiki gihingwa. Ikigaragara ni uko ingaruka zo kuvura BA + GA3 zivuye hejuru kuruta iya GA cyangwa BA yatanzwe wenyine. Acide ya Gibberellic yongera umubare wamababi mashya. Mugihe amababi mashya akura, kongera umubare wamababi mashya birashobora kugabanya imikurire yamababi39. GA yavuzwe ko izamura ubwikorezi bwa sucrose kuva mu mwobo kugera mu ngingo 40,41. Byongeye kandi, gukoresha GA mu buryo budasanzwe ku bimera bimaze imyaka myinshi bishobora guteza imbere imikurire y’ibimera nkamababi n’imizi, bityo bikarinda guhinduka kuva mu bimera kugera ku mikurire y’imyororokere42.
Ingaruka za GA mukwongera ibimera byumye bishobora gusobanurwa no kwiyongera kwa fotosintezeza kubera kwiyongera kwamababi43. GA yavuzwe ko itera ubwiyongere bwibibabi bya Maize34. Ibisubizo byerekanaga ko kongera BA yibanze kuri 200 mg / L bishobora kongera uburebure numubare wamashami yisumbuye hamwe nubunini bwumuzi. Acide ya Gibberellique igira ingaruka kumikorere ya selile nko gukurura ingirabuzimafatizo no kuramba, bityo bigatuma imikurire ikura43. Byongeye kandi, HA yagura urukuta rw'utugingo ngengabuzima ya hydrolyzing mu isukari, bityo igabanya ubushobozi bw'amazi y'akagari, bigatuma amazi yinjira mu kagari kandi amaherezo biganisha ku kurambura selile44.
