Tétel Szabadon hozzáférhető Effects of activated charcoal on rooting of in vitro apple (Malus domestics Borkh.) shoots(2001) Magyarné Tábori, Katalin; Dobránszki, Judit; Jámborné Benczúr, Erzsébet; Lazányi, János; Szalai, J.Tétel Szabadon hozzáférhető Effects of activated charcoal on rooting of in vitro apple (Malus domestics Borkh.) shoots(2001-03-21) Magyar-Tábori, K.; Dobránszky, J.; Jámbor-Benczúr, E.; Lazányi, J.; Szalai, J.Rooting of in vitro 'Royal Gala' shoots was studied under different conditions of root induction and root elongation phase. The rooting capacity was affected by both rooting phases. Very high rooting percentage could be reached with both liquid and solid root induction media. Raising the temperature from 22 °C to 26 °C during root induction phase increased the rooting percentage. Presence of activated charcoal in root elongation media can affect the number of roots per rooted shoots and can increase the rooting percentage, the length of roots and the rate of survival depending also on other conditions during rooting. Presence of NAA in root elongation media reduced the number and the length of roots considerably. Favourable effect of activated charcoal on rooting was mainly due to adsorption of NAA.Tétel Szabadon hozzáférhető Effects of indole-3-butiricacid levels and acivated charcoal on rooting of in vitro shoots of apple rootstocks(2002) Magyarné Tábori, Katalin; Dobránszki, Judit; Jámborné Benczúr, Erzsébet; Lazányi, János; Szalai, J.; Ferenczy, AntalTétel Szabadon hozzáférhető Effects of indole-3-butyric acid levels and activated charcoal on rooting of in vitro shoots of apple rootstocks(2002-10-16) Magyar-Tábori, K.; Dobránszky, J.; Jámbor-Benczúr, E.; Lazányi, J.; Szalai, J.; Ferenczy, A.Rooting responses of rootstocks cvs. JTE-F1, M. 26 and MM. 106 were studied to different concentration of IBA in root induction media and to presence of activated charcoal in root elongation media. High rooting rate (>90%) could be achieved in cvs. JTE-H and M. 26, while cv. MM. 106 showed weak rooting ability at each IBA level tested. Increasing IBA content depressed the rooting only in cv. M. 26. Presence of activated charcoal decreased considerable the rooting rate in cv. M. 26 and decreased the number of roots in cvs. JTE-H and M. 26. These cultivars developed longer roots on media containing activated charcoal, while cv. MM. 106 did not showed any reaction for it.Tétel Szabadon hozzáférhető In vitro shoot multiplication of apple: comparative response of three rootstocks to cytokinines and auxin(2000) Dobránszki, Judit; Abdul-Kader, A.; Magyarné Tábori, Katalin; Jámborné Benczúr, Erzsébet; Bubán, T.; Szalai, J.; Lazányi, JánosTétel Szabadon hozzáférhető In vitro shoot multiplication of apple: comparative response of three rootstocks to cytokinines and auxin(2000-02-23) Dobránszky, J.; Abdul-Kader, A.; Magyar-Tábori, K.; Jámbor-Benczúr, E.; Bubán, T.; Szalai, J.; Lazányi, J.Shoot multiplication responses of rootstocks cvs. M.26, MM.106 and JTE-H to different concentration of BA, BAR and IBA in eight various combinations were tested on MS-medium. The effect of hormones depended on genotype, type of cytokinin and interaction of cytokinin and auxin. Shoot multiplication was significantly enhanced with the use of BAR as cytokinin. High multiplication rate could be achieved in cvs. M.26, MM.106 and JTE-H: 7.7, 6.9 and 9.9 shoots per explant, respectively.Tétel Szabadon hozzáférhető Influence of aromatic cytokinins on shoot multiplication and their after-effects on rooting of apple cv. Húsvéti rozmaring(2000) Dobránszki, Judit; Magyarné Tábori, Katalin; Jámborné Benczúr, Erzsébet; Lazányi, János; Bubán, T.; Szalai, J.Tétel Szabadon hozzáférhető Influence of aromatic cytokinins on shoot multiplication and their after-effects on rooting of apple cv. Húsvéti rozmaring(2000-08-23) Dobránszky, J.; Magyar-Tábori, J.; Jámbor-Benczúr, E.; Lazányi, J.; Bubán, T.; Szalai, J.Different aromatic cytokinins (BA, BAR, TOP and KIN ) were tested alone or in combination for the shoot proliferation response of ‘ Húsvéti rozmaring' apple scion. The best multiplication rate was achieved by dual cytokinin application (1 mg 1- 1 BA + 1.5 mg 1 -1 KIN). The rooting capacity was affected considerably by the position of shoots: transfer of the three-week-old shoots to the same or other proliferation medium in vertical position inhibited the following rooting totally. Post-effects of different cytokinins (BA and TOP) on subsequent rooting could be detected: BA increased the number of roots markedly, while TOP resulted in significantly longer roots.Tétel Szabadon hozzáférhető Post-effects of cytokinins and auxin levels of proliferation media on rooting ability of in vitro apple shoots (Malus domestica Borkh.) 'Red Fuji'(2001) Magyarné Tábori, Katalin; Dobránszki, Judit; Jámborné Benczúr, Erzsébet; Bubán, T.; Lazányi, János; Szalai, J.; Ferenczy, AntalTétel Szabadon hozzáférhető Post-effects of cytokinins and auxin levels of proliferation media on rooting ability of in vitro apple shoots (Malus domestica Borkh.) 'Red Fuji'(2001-09-11) Magyar-Tábori, K.; Dobránszky, J.; Jámbor-Benczúr, É.; Bubán, T.; Lazányi, J.; Szalai, J.; Ferenczy, A.Rooting ability of in vitro apple shoots of 'Red Fuji' grown on proliferation media with different hormone content were tested at three IBA levels in root induction media. Rooting percentage could be slightly increased with an increase in IBA concentration in proliferation media. The highest IBA concentration (3.0 mg 1 -1 ) in root induction media showed strong inhibitory effect on rooting capacity of in vitro shoots. The highest rooting percentage (95%) could be achieved by shoots grown on proliferation media containing TOP or BA+KIN as cytokinins before rooting.Tétel Szabadon hozzáférhető Single and dual effects of different cytokinins on shoot multiplication of different apple scions(2000) Dobránszki, Judit; Abdul-Kader, A.; Magyarné Tábori, Katalin; Jámborné Benczúr, Erzsébet; Bubán, T.; Szalai, J.; Lazányi, JánosTétel Szabadon hozzáférhető Single and dual effects of different cytokinins on shoot multiplication of different apple scions(2000-08-23) Dobránszky, J.; Abdul-Kader, A.; Magyar-Tábori, K.; Jámbor-Benczúr, E.; Bubán, T.; Szalai, J.; Lazányi, J.Shoot multiplication responses of three apple scions to different concentrations of BA and BAR as single source of cytokinins and in combination with two concentrations of KIN were studied. The effects of hormones depended on genotype, type and interactions of different cytokinins. Use of BAR significantly enhanced the shoot multiplication of cv. Jonagold (6.5 shoots per explant). The multiplication rate of cv. Jonagold could not be improved by using the combination of BAR and KIN. The best proliferation was achieved by 1.0 mg 1 -1 BA combined with 1.0 mg 1 -1 KIN of cv. Prima..(8.1) and of cv. Galaxy (10.4).The effect of 0.5 mg 1 -1 BA along with 1.5 mg 1 -1 KIN was similar on multiplication rate (10.9) of cv. Galaxy.
