Abstract Banding with Velcro™ of new shoot growth in moderately difficult-to-root apple rootstock MM.106 (Malus domestica Borkh.) for 7 days prior to taking cuttings, and treatment of cuttings with 500 to 2000 ppm indolebutyric acid (IBA) increased both percent rooting and root number. Banding, however, did not influence the rooting of easy-to-root Franklinia alatamaha Marsh. IBA at 0 to 1000 ppm induced a logarithmic increase in percent rooting of cuttings of MM.106 and root number of cuttings of Franklinia; but, higher levels of IBA reduced both. Banding prevented the rooting inhibition found at high concentrations of IBA in cuttings of MM.106, while simultaneously stimulating lateral budbreak and greater root number. Stem banding improved the establishment of cuttings treated with 1000 ppm and 2000 ppm IBA. Without banding, establishment of these cuttings was markedly decreased.

Softwood shoots of apple (Malus domestica Borkh.) rootstocks M.9 and MM.106 were banded with Velcro for up to 20 days before cuttings were propagated. Percent rooting and the number of roots per cutting were significantly improved by banding for 10 to 20 days, with and without IBA application. As the duration of stem banding increased from 0 to 20 days, percent rooting and the number of roots of both M.9 and MM.106 cuttings increased linearly or curvilinearly. Stem banding also stimulated budbreak of cuttings. In M.9, banding resulted in a higher survival rate and increased new shoot growth of transplanted cuttings after 4 months. Percent budbreak and new shoot growth were highly correlated with the number of roots per cutting in both cultivars. The effects of stem banding on budbreak and subsequent growth of the cuttings were largely due to the enhanced rooting of cuttings. Chemical names used: 1H-indole3-butyric acid (IBA).

Abstract Greenwood cuttings from greenhouse-produced tamarack seedlings and 3- to 10-year-old tamarack wildlings transplanted from natural stands in north-western Ontario were rooted under mist in peat-vermiculite. Eighty-five percent of cuttings from seedlings rooted; treatment with indolebutyric acid increased number of roots per cutting, but not rooting percent. At 6 weeks after planting, rooting of cuttings from wildlings averaged 66%, and at 12 weeks, 91%. Twelve-week rooting percent of cuttings from individual ortets ranged from 12 to 100, but cuttings from the majority of ortets exhibited 100% rooting. Nearly all rooted cuttings survived overwintering outdoors and initiated normal shoot growth after forcing in mid-winter. The described propagation system is recommended for production of container stock for tamarack plantations. North. J. Appl. For. 3:91-93, Sept. 1986.

Redistribution of boron (B) within apple trees (Malus domestica Borkh.) as a result of leaf B application was examined. The experiments were canied out in a greenhouse on M.26 apple rootstock and in field conditions on five-year-old 'Elstar' and 'Szampion' apple trees grafted on M.26 rootstock. Boron was applied in a form of boric acid solution. It was found that leaf B application resulted in movement of B to leaves, flowers and apple fiuits untreated with B. These results clearly showed that B was retranslocated within apple tree. The retranslocation of B within apple trees took place when leaf B applications were done both in summer and autumn. Additionally, it was observed that B from leaf application had paiticularly high ability of movement within plant at insufficient B content (0,2μM) in solution. Generally, these data indicated that B within apple trees was transported in phloem, however mechanism of this phenomenon has not been well known yet. Thus, leaf B application of apple trees can be more successful treatment in reduction of B deficiency in plants compared to soil B application.
