Abstract: A process of propagating woody plant material of apple, plum or cherry in vitro includes setting a shoot on a nutrient medium including a cytokinin, an auxin and a phenolic compound to produce a number of shoots, excising these shoots and allowing them to multiply again as the same medium any desired number of times, excising individual shoots and rooting these on the same or a similar nutrient medium but from which the cytokinin is omitted and finally growing the resulting plants on.

Abstract: A new and distinct variety of ornamental crab apple tree is provided which xhibits an extremely columnar growth habit which generally resembles that of a vertical pole.

Abstract: A new and distinct variety of apple tree is provided which exhibits an exmely columnar growth habit which generally resembles that of a vertical pole. The foliage is dense and compact and side branches are substantially absent. The new variety yields medium-sized asymmetric generally flat round fruit having a yellow-green skin coloration which is partially overlaid with light orange. The unique growth habit makes possible plantings of extremely high density with concomitant increased fruit yields per planting area.
