Sarudzo Itsva Yekusimudzira Kubereka Miti Yemichero: Magadzirirwo Ekukura Kwezvirimwa Regulators Sainzi Inogadzirisa Kukura Maharare.
Miti inogadzirisa kukura kwezvirimwa ikirasi yemakemikari zvinhu-zvakagadzirwa zvechisikigo kana kutorwa zvakasununguka-zvinokwanisa kugadzirisa kukura nekusimudzira maitiro emiti. Maitiro avo epakati echiito ari mukutevedzera kana kukanganisa kufambiswa kwechiratidzo cheendogenous chirimwa mahomoni (akadai seauxins, cytokinins, uye gibberellins), nekudaro achipesvedzera maitiro emuviri senge kupatsanurwa kwesero, kurebesa, kusiyanisa, uye kuumbwa kwenhengo. Muchikamu chezvekurima, kushandiswa kwezvinhu izvi kunopa nzira yesainzi yekuwedzera goho rezvirimwa, kuvandudza mhando, uye kusimbisa kusagadzikana.
Tora Brassinolide semuenzaniso:ine 0.2% inoshanda, inoshanda seyakaderera-chepfu, inonyungudika nemvura amino acid-based foliar fetireza. Kana yakanyungudutswa 5,000-yakapetwa uye yakapfapfaidza pamashizha emuti wemichero, inosimudzira zvakanyanya kutamiswa kwezvigadzirwa zvephotosynthetic kumuchero uku panguva imwe chete ichidzora kuenzana kwemahomoni emukati mukati memuti, nekudaro ichideredza kuitika kwemaruva uye kudonha kwemichero. Data yekuedza inoratidza kuti mushure mekushandisa katatu kwakatevedzana pamiti yemichero yakaita semaapuro nemaranjisi, huremu hwepakati pamuchero hunowedzera ne15% -20%, uye chiyero cheshuga-ku-asidhi chinowedzera kugadziridzwa. Maitiro ayo ekuita anosanganisira activate receptor mapuroteni pane cell membranes kuti iwedzere kusimba kwechirimwa chekudyara, panguva imwe chete ichikurudzira kutaura kwemajini ane chekuita nekushushikana kuwedzera kushivirira kwemuti wemichero kumamiriro akashata akadai sekusanaya kwemvura uye kudziya kwakaderera.
Kubva pakuona kwekuchengetedza, acute oral toxicity yeBrassinolide inongori 0.0000000004, uye acute dermal toxicity ndeye 0.000000067-nhamba iri pazasi pezvikumbaridzo zvekuchengetedza zvakatemerwa mishonga inouraya zvipembenene. Kunyungudika kwayo kwemvura kunogonesa kupararira kwemushonga wekupfapfaidza pamativi emashizha, nokudaro zvichidzikamisa njodzi yephytotoxicity inokonzerwa nekuwanda kwakanyanya kwenzvimbo. Nezve kudzora dosi, chiyero che dilution che 0.2% -0.5% chinokwana kusangana nekukura kwemirau zvinodiwa uku uchidzivirira nyaya dzakaita senge nguva isati yakwana senescence kana michero malformation inogona kubva mukunyanya kushandiswa. Zvakakosha kuziva kuti kushanda kwevatongi ava kunonyanya kukonzerwa nenguva yekushandiswa; saka, zvinokurudzirwa kuzvishandisa panguva dzakakosha dzekukura-zvakadai sechikamu chekusiyanisa maruva uye chikamu chekuwedzera kwemichero-kuti uwane migumisiro yakakwana yekutonga.
Muchiito chekurima chemazuva ano, kushandiswa kwezvigadziridzo zvekukura kwezvirimwa zvakashanduka kubva kune-single-function application kusvika kune-multi-functional, nzira dzakabatanidzwa. Kuburikidza nekuita kwe synergistic kwezvikamu zvakasiyana-siyana, zvinangwa zvakawanda-zvakadai sekusimudzira kukura, kuwedzera kusagadzikana kwekunetseka, nekuvandudza kunaka-zvinogona kuwanikwa panguva imwe chete. Iyi shanduko yetekinoroji inoratidza kudiwa kwezvekurima kwemazuva ano kwemitemo chaiyo uye inopa maonero matsva ekugadzirisa matambudziko ekugadzirwa kwakasimba pakati pezvimhingamipinyi zvezviwanikwa.
