Bo v prihodnosti seme novo zlato, je ve\u010dkrat zastavljeno vpra\u0161anje. Moj odgovor poznate. Seme je ve\u010d kot zlato. Vrednost semen bi morali meriti v zlatu. Pa jejte zlato, \u010de lahko. Jaz bom raje krompir.<\/p>\n\n\n\n

Ne maram hibridov. Gledano z vidika pridelave in shranjevanja semen, niso uporabni. Lepo zapakirana vsebina z krasno naslovnico, znotraj kdo ve. Ne bodo vam takoj pokazali svojega pravega obraza, \u0161ele, ko je \u010das za pobiranje sadov dela. Energije v takih rastlinah niso dobre. Prav tako takim rastlinam pravijo, da so brez prihodnosti.<\/p>\n\n\n\n

Hibridna semena (F1)<\/strong> <\/h2>\n\n\n\n

Saj ste verjetno opazili v semenarnah tudi hibridna semena, ozna\u010dena z oznako F1, ki obetajo zelo obilen pridelek. Kaj pomenijo te oznake F? F1 je potomec, ki je nastal z direktnim kri\u017eanjem dveh star\u0161evskih rastlin. Gre za kri\u017eance, ki jih pripravijo z dolo\u010denimi postopki in ta semena vzklijejo le enkrat.<\/p>\n\n\n\n

Potem iz teh F1 nastanejo nova semena in \u010de bi ta na novo nastala semena \u017eeleli uporabiti \u0161e naslednje leto, bi bil pridelek majhen in slab. Dobili smo namre\u010d  F2. Seme F2 ni kaljivo ali pa slabo kaljivo, lastnosti rastlin pa so celo slab\u0161e od starih star\u0161ev P.<\/p>\n\n\n\n

Potem je pa \u0161e oznaka P. Ta ozna\u010duje star\u0161evsko rastlino, ki mora biti \u010dista sorta! Torej: kri\u017eanje dveh P je F1 seme, samooploditev F1 pa je F2 seme.<\/p>\n\n\n\n

Ob uporabi F1 hibridnih semen, se moramo vsako leto vrniti v semenarno in kupiti nova, \u010de \u017eelimo imeti kaj pridelka. Nikoli nisem razumele te logike. A je \u010dudno, da se kmetijstvo ne spla\u010da. Z mano se prav gotovo ne strinjajo proizvajalci hibridnih semen in semenarne, ki jih prodajajo. Ste mogo\u010de opazili, da je med konvencionalnimi semeni na voljo zmeraj ve\u010d hibridov. 70% pravijo, da jih je. Ne verjamete, poglejte malo med krmnimi rastlinami.<\/p>\n\n\n\n

Me veseli, da je bilo opaziti, da razne v\u010dasih poznane sorte izginjajo iz prodajnih polic semenarn. Saj pravim, jaz hodim tja na ekskurzijo. Sicer ne tako pogosto kot bi \u017eelela, zato pa bolj opazim razliko.<\/p>\n\n\n\n

Poglejmo \u0161e drugo plat zgodbe. Kaj o hibridnih semenih pravijo pridelovalci in semenarne<\/strong>.<\/h2>\n\n\n\n

Glavni namen je povi\u0161ati tr\u017eni pridelek na enoto.  Populacija raste, rabimo ve\u010d hrane. Res? Po\u017eremo zmeraj ve\u010d, na\u0161a prehrana pa je zmeraj bolj osiroma\u0161ena. Namesto enega doma\u010dega jabolka mora\u0161 pojesti tri kupljene za isto vrednost hranilnih snovi, mineralov, vitaminov, karkoli. Posplo\u0161ujem, ampak nekaj v tem smislu.<\/p>\n\n\n\n

Prihaja do zaostrenih pogojev pridelave, kjer bo imel veliko te\u017eo pravilni izbor hibridov, kateri bodo lahko bolj kljubovali raznim stresom iz okolja. Predvsem bo pomembna ve\u010dja odpornost na bolezni (glivi\u010dne in virusne) in ve\u010dja tolerantnost na napade \u0161kodljivcev. To pomeni, da se bo hibrid v ve\u010dji meri sam sposoben upreti napadu bolezni ali \u0161kodljivcev iz okolja, kar za posledico prinese manj pogosto za\u0161\u010dito s fitofarmacevtskimi sredstvi oz. drugimi repelenti. Mislim bedarija, doma\u010de vrste pa to niso?<\/p>\n\n\n\n

Pa \u0161e tretja plat zgodbe<\/strong><\/h2>\n\n\n\n

Tudi do dana\u0161njih sort ne bi pri\u0161li brez kri\u017eanja. Recimo kumarice za vlaganje. \u010ce posejemo hibridna semena, je pridelek veliko ve\u010dji kot, \u010de sejemo navadna doma\u010da semena. Potem brokoli in cveta\u010da. S hibridnimi semeni sem pri\u0161la do odli\u010dnega pridelka. Tudi glavnati ohrovt iz hibridnih semen zagotovo naredi kakovostne glave. Tudi ne dr\u017ei \u010disto, da iz semen hibridov ni nikoli ni\u010d uporabnega.  Poglejmo krompir. Po pravici vse kar kupite je hibrid. Re\u010dejo vam, da ga lahko sadite maksimalno dve, v najbolj\u0161em primeru tri leta. Potem obvezno kupite novo seme. No, ne dr\u017ei. Preizku\u0161eno. Koruza isto. Je pa res, pripravljeni morate biti tudi na presene\u010denja. Na primer paradi\u017enik. Iz hibrida lahko dobite naslednje leto tri razli\u010dne vrste paradi\u017enika. Ali ni zanimivo?<\/p>\n\n\n\n

Kot povsod drugod ni vse \u010drno, niti ne belo. Ampak dokler ni gensko predelano je odli\u010dno.<\/p>\n","protected":false},"excerpt":{"rendered":"
