Isicelo
2.1 Ukuze ufumane isiphumo?
I-Ethephon ngumlawuli wokukhula kwezityalo.Ineempembelelo zomzimba zokuphucula ukukhuselwa kwehomoni, ukukhawulezisa ukuvuthwa, i-abscission, i-senescence kunye nokukhuthaza iintyatyambo.Ngaphantsi kweemeko ezithile, i-ethephon ayikwazi ukukhulula i-ethylene ngokwayo, kodwa iphinda ibangele izityalo ukuba zivelise i-ethylene.
2.2 Iza kusetyenziswa kweziphi izityalo?
Ikhukhamba, i-zucchini, ithanga, i-tomato, i-watermelon, njl.
2.3 Umthamo kunye nokusetyenziswa
| Uqulunqo | Amagama ezityalo | Lawula into | Umthamo | Indlela yokusebenzisa |
| 40% SL | Umqhaphu | khawulezisa ukuvuthwa | 300-500 amaxesha ulwelo | Ukutshiza ngomphunga kunye namagqabi |
| Umthi werabha | ukwandisa imveliso | 5-10 amaxesha ulwelo | ipeyinti | |
| Umqhaphu | ukwandisa imveliso | 300-500 amaxesha ulwelo | Ukutshiza ngomphunga kunye namagqabi |
3.Indlela yokwenza
I-Ethephon, njenge-ethylene, iphakamisa kakhulu amandla e-RNA synthesis kwiiseli kwaye ikhuthaza ukuhlanganiswa kweeprotheni.Kwindawo yezityalo abscission, ezifana petiole, isiqu isiqhamo kunye nesiseko petal, ukwanda protein synthesis ikhuthaza re synthesis cellulase kwi layer abscission, kuba ikhawulezisa ukwakheka umaleko abscission kwaye kukhokelela abscission ilungu.I-Ethephon inokunyusa umsebenzi we-enzymes, isebenze i-phosphatase kunye nezinye i-enzymes ezinxulumene nokuvuthwa kweziqhamo, kunye nokukhuthaza ukuvuthwa kweziqhamo.Kwizityalo ze-senescent okanye ezithintekayo, utshintsho lwe-peroxidase lubangelwa yi-Ethephon ekhuthaza i-protein synthesis.I-ethylene inokuthintela ukuhlanganiswa kwe-auxin engapheliyo kunye nokulibazisa ukukhula kwezityalo.
