I-Floriculture iwumkhakha wezolimo obaluleke kakhulu emhlabeni wonke futhi onomthelela omkhulu kwezenhlalo nezomnotho.Ama-roses enza ingxenye enkulu yazo zonke izimbali ezitshaliwe.Ngemva kokuvunwa kwezimbali, izinga lokushisa liyisici esizithinta kakhulu.Lesi yisikhathi sokuhlola izindlela zokupholisa ezihlukene ezisetshenziswa ngemva kokuvunwa kwama roses, ngokulinganisa imiphumela yawo phezu kobude bezimbali kanye nokunye okuguquguqukayo kwekhwalithi.Imiphumela eyinsalela yokwenziwa, umoya ophoqelelwe kanye nezindlela zokupholisa i-vacuum yahlolwa, ngemva kokulingiswa kwezokuthutha.Ukuhlolwa kwenziwa epulazini elithumela izimbali kwamanye amazwe.Kwatholakala ukuthi lezo zimbali ezichayeke ekupholiseni i-vacuum zibonise ukuphila isikhathi eside kanti lezo ezithatha umoya ophoqelelwe zinezinga eliphansi kakhulu.
Imbangela enkulu yokuqedwa kwezimbali kwaba ukuba khona kwe-Botrytis (44%) kanye ne-dormancy (35%).Akukho mehluko obalulekile ezimbangela ezinjalo owatholakala phakathi kwezindlela zokwelapha ezihlukahlukene zokupholisa;nokho kwaqashelwa ukuthi lezo zimbali ezadlula ezindleleni zokupholisa umoya ezingenzi lutho neziphoqelelwe zabonisa ukuba khona kwe-Botrytis ngokushesha kakhulu kunalezo ezichayeke ekupholiseni kwevacuum.Ngaphezu kwalokho intamo egobile ku-vacuum epholile izimbali ibonwa kuphela ngemuva kosuku lwe-12 ngenkathi kwezinye izindlela zokwelapha ezenzeka ezinsukwini ezinhlanu zokuqala zokuhlolwa.Ngokuphathelene nenani leziqu ezithintekile ngenxa yokuphelelwa amanzi emzimbeni, akukho mehluko otholakele phakathi kwazo zonke izindlela zokwelapha, eziphikisa inkolelo evamile yokuthi ukupholisa i-vacuum kusheshisa ukuphelelwa amanzi emzimbeni kweziqu zezimbali.
Izinkinga ezinkulu ezihlobene nekhwalithi yezimbali ngesikhathi sesigaba sokukhiqiza ukuvunwa okungafanele ngobude bezinhlanga kanye nesiteji esinqunyiwe sokuvula, iziqu ezigobile, ukulimala kwemishini kanye nezinkinga zokukhucululwa kwendle.Okuhlobene nokuvuna emva kokuvuna ukuhlukaniswa kanye nokwakheka kwenqwaba, ukuwohloka, ukufakwa kwamanzi kanye neketango elibandayo.
Izimbali ezintsha ezisikiwe zisasebenza futhi zisebenza ngokusebenza kwe-metabolic ngakho-ke zingaphansi kwezinqubo ezifanayo zomzimba njengesitshalo.Nokho, ngemva kokusikwa ziwohloka ngokushesha, ngaphansi kwezimo ezifanayo zemvelo.
Ngakho-ke, ubude bezimbali ezisikiwe bunqunywa yizici ezifanayo ezithinta ukukhula kwezitshalo, njengezinga lokushisa, umswakama, amanzi, ukukhanya nokutholakala kwezakhi.
