Brassinolide

I-BrassinoLide uhlobo olusha loMlawuli Wokukhula Kwesitshalo, owaqala ukutholwa ososayensi bezolimo baseMelika ngo-1970. Qhathaniswa nabanye abalawuli abahlanu abakhula, i-Brassinolactone ine-UnidiRectional Perertence futhi ibizwa ngecala lesithupha lama-hormone ezitshalo. Namuhla ukuhlaziya le ngxenye, ngithemba ukuthi ungaqonda, ukusetshenziswa okuyikho kwe-Brassinolactone.

I-Brassinolide akuyona umanyolo we-foliar. Umanyolo we-foliar ungumanyolo wezakhi (isib. Ilawula ukukhula kwezilimo ngokungaqondile ngokulawula uhlelo lwe-hormone oluphelele lwezitshalo, futhi lunokuhambisana okuhle noMnyolo we-Foliar.

Indima ye-Brassinolactone

1. Khuthaza ukukhula kwezimpande kwezilimo esiteji sesithombo

Kusetshenziswa njengokwelashwa kwembewu noma ukufafaza kwesiteji okuvinjelwe, kunomphumela wokukhula okusobala ezimpandeni zezithombo zelayisi, ukolweni, imifino kanye nezinye izitshalo) I-50%, futhi isisindo esomile sanda ngo-15% -107%.

2. Khuthaza ukukhula ngesikhathi semifino

I-Brassinolide inomphumela ophambili wokukhuthaza ukuhlukaniswa kwamaseli kanye nokuqothuka kwamaseli, kepha futhi kungakhuphula okuqukethwe kwe-chlorophyll kumaqabunga, athuthukise isithombe semikhiqizo ye-Photocontract, ngakho-ke kunomphumela osobala wokuqhakambisa ukukhula kwezimila zezitshalo, futhi kungakhuphula isivuno Veza.

3. Khuthaza ukukhula kwezithelo ngesikhathi sokuzala kwezilimo

I-BrassinoLide ingathuthukisa izinga lokuhluma kwempova, likhuthaze ukunwebeka kwempova yempova, futhi luhlose ukukhiqizwa kwezitshalo, ukuze uthuthukise izinga lokusetha imbewu nezinga lokusetha izithelo. Inombolo yokusanhlamvu nesisindo sezilimo zokusanhlamvu kwanda esiteji esivuthiwe, futhi izithelo zamakhabe nezithelo zibonisa izithelo ezifanayo, ezathuthukisa ikhwalithi yezilimo.

4. Khulisa ukumelana kwengcindezi

Ngemuva kokungena emzimbeni wesitshalo, i-Brassinolide ayigcini nje ngokukhulisa i-photosynthesis, inyusa ukukhula nokuthuthuka, kepha futhi ivuselela imisebenzi yamanye ama-enzyme avikelekile emzimbeni wesitshalo, esinganciphisa kakhulu ukulimala okubangelwa izinto ezijwayelekile ezibangelwa izinto eziyingozi (njenge-malondiyaldehyde, njll .) Kukhiqizwe isidumbu sesitshalo ngaphansi kwengcindezi.
