Yakajairika brassinolide mhedzisiro uye shandisa matanho ekuzvidzivirira

Mumakore achangopfuura, brassinolide, serudzi rutsva rwekukura kwezvirimwa, yakashandiswa zvakanyanya mukugadzirwa kwekurima, uye mashiripiti ayo ekuwedzera goho akafarirwa nevarimi.

Brassinolide haisi chinhu chimwe chete, asi izwi rakajairika rekirasi ye steroidal chirimwa mahomoni. Ivo varipo mune zvidiki zvishoma muzvirimwa, asi vanoita basa rakakosha rekutonga mukukura nekukura kwechirimwa. Parizvino, kune marudzi anopfuura makumi manomwe anozivikanwa ebrassinolide, pakati pawo 24-epibrassinolide, 28-homobrassinolide, 28-epihomobrassinolide, nezvimwewo. Kunyangwe iwo ese ari ebrassinolide, nekuda kwekusiyana kusinganzwisisike muchimiro chemakemikari, mhedzisiro yadzo mukusimudzira kukura, kuramba kushushikana, uye kuwedzera goho zvine maonero akasiyana.

Mhando dzakasiyana dzebrassinolide dzine mhedzisiro dzakasiyana

Tora akati wandei akajairika brassinolides semuenzaniso:
24-epibrassinolide:
Tichitarisa pakusimudzira kukura kwemidzi nekusimudzira kusamira zvakanaka kwechirimwa, kunyanya pasi pemamiriro akashata akadai sekusanaya kwemvura nemunyu, zvinokwanisa kuvandudza mararamiro uye goho rezvirimwa. Inogona kukurudzira kupatsanurwa uye kurebesa kwemasero emidzi, kuwedzera midzi yenzvimbo, uye kugadzirisa kugona kwemvura uye chikafu. Kune zvirimwa muchikamu chembesa, kushandiswa kwe24-epibrassinolide kunogona kukurudzira kukura kwemidzi nekukurumidza uye kuisa hwaro hwakasimba hwekukura kwekupedzisira.

28-homobrassinolide:
Inonyanya kushanda pakukura kwemiti yemiti uye mashizha, inosimudzira kupatsanurwa kwesero uye kureba, inoita kuti zvirimwa zvisimbe, mashizha akakora uye akakura, nokudaro achivandudza photosynthetic kunyatsoshanda. Inogonawo kukurudzira kukura kwemichero, kuwedzera goho uye kunaka. Inoshandiswa zvakanyanya muzvirimwa zvakaita semiriwo nemichero, uye inogona kuwedzera zvakanyanya goho uye kukosha kwezvinhu.

28-epihomobrassinolide:
Iine maitiro maviri ekusimudzira kukura uye kuwedzera kusagadzikana kusagadzikana. Haikwanisi chete kukurudzira tsinde uye kukura kwemashizha, asiwo kuvandudza kupikisa kwezvirimwa kune nzvimbo dzakaipa. Kunyange ichivandudza goho nemhando yepamusoro, inogona zvakare kusimudzira kugona kwembesa kurwisa zvirwere netumbuyu, kuderedza kushandiswa kwemishonga yezvipembenene, uye kuenderana negwara rekusimudzira kurima kwegirinhi.

Kushandiswa kwesainzi kunogona kuwana zvikomborero zvikuru
Nzira dzekushandisa dzeBrassinolide dzinonyanya kupfapfaidza foliar uye kudiridza midzi yevhu. Kupfapfaidza foliar kunotora nekukurumidza uye kune kukurumidza kuita, iyo inokodzera mamiriro ezvinhu apo kukurumidza kudya kunovaka muviri kunodiwa kana kutarisana nekukasira kutambudzika. Kudiridza midzi yevhu kunotora zvishoma nezvishoma uye kune simba rinogara kwenguva refu, iro rakakodzera kusimudzira kukura kwemidzi nekuvandudza kushushikana kwese kwezvirimwa.

Sarudzo yenzira yekushandisa zvinoenderana nerudzi rwechirimwa, danho rekukura uye zvinodiwa chaizvo. Semuyenzaniso, pambesa padanho rembeu, kudiridza midzi yevhu kunogona kushandiswa kukurudzira kukura kwemidzi; kuzvirimwa munguva yekukura kwakasimba, kumwaya mashizha kunogona kushandiswa kukurudzira madzinde nemashizha kukura uye kukura kwemichero; kune zvirimwa zvinotambura netumbuyu nezvirwere kana dambudziko, kupfapfaidza foliar kunogona kushandiswa kukurumidza kuwedzera zvinovaka muviri uye kuwedzera kusagadzikana kwekushushikana.
