I-6-Benzylaminopurine yi-cytokinin yokwenziwa ekhuthaza ukuhlukana kweeseli kunye nokuqokelela izondlo kwiingcambu ezingaphantsi komhlaba kunye nezityalo ze-tuber ngokulawula iinkqubo ze-physiological plant, ngaloo ndlela ukwandisa isivuno kunye nokuphucula umgangatho.
Indlela apho i-6-Benzylaminopurine ikhuthaza ukuhlukana kweeseli kwiingcambu ezingaphantsi komhlaba kunye nezityalo ze-tuber ikakhulu ibandakanya ukuvuselela ukubonakaliswa kwejenethi enxulumene nokwahlulwa kweseli kunye nokukhawulezisa ukwanda kweeseli ze-meristematic. Kwiingcambu ezingaphantsi komhlaba kunye nezityalo ze-tuber ezifana neetapile kunye neeyam, i-6-BA inokunyusa kakhulu inani leeseli kwii-tubers okanye i-rhizomes. Umzekelo, xa isetyenziswe ngokudibeneyo ne-Forchlorfenuron (CPPU), inokunyusa inani leeseli zetapile ze-tuber ngama-25% -30% kwaye ngaxeshanye inyuse izinga lokukhula kwe-yam rhizomes nge-20% -25%.
Indlela yokusebenza kwayo ibandakanya ukubangela ukuhlukana kwezicubu ezingabonakaliyo kunye nokukhuthaza ukubunjwa kwehlumela, ngaloo ndlela kukhuthaze ukuphuhliswa kwamalungu angaphantsi komhlaba.
Ngokumalunga nokuqokelelwa kwezondlo, i-6-Benzylaminopurine iphucula ukuhlanganiswa kwezinto ezifana nesitashi ngokulawula ukuthuthwa kunye nokuhanjiswa kweemveliso ze-photosynthetic. Ikhuthaza ukuhanjiswa kwe-amino acids kunye noshukela kwiingcambu. Ngokomzekelo, kwiibhatata, inokunyusa umlinganiselo weemveliso ze-photosynthetic ezabelwe iibhubhu ukuya ngaphezulu kwe-70%, inyusa ubunzima beetyhubhu nganye nge-18% -22%. Ngaxeshanye, ngokudityaniswa kwe-potassium ye-chelated kunye ne-calcium, ivuselela umsebenzi we-starch synthase (SS) kunye ne-sucrose synthase (SPS), ukwandisa umxholo we-starch of bulbs bulbs nge-15% -20%.
Ixesha lokufakwa kwesicelo: Kwizityalo eziphantsi komhlaba (ezifana neitapile kunye nejinja), kuyacetyiswa ukuba kutshizwe ngexesha lokuhlakula kade okanye kwinqanaba lokuqala lokukhulisa i-tuber ukukhuthaza ukwahlukana kweeseli kunye nokuqokelelana kwezondlo.
Ukulawulwa koxinzelelo: Uxinzelelo olucetyiswayo ngu-5-8 g / L (oko kukuthi, 5000-8000 mg / L). Ugxininiso olugqithisileyo kufuneka luthintelwe ukuthintela ukukhula okugqithisileyo kwezityalo okanye ukukhubazeka.
