The effect of shoot bending and other cultivation practices on the lateral floral bud formation of "Hosui" pear grown in Taiwan highland area.

Experiments were conducted in 1992-96 in a pilot pear (Pyrus serotina [P. pyrifolia]) orchard at the Experimental Highland Farm of the National Taiwan University, Mei-feng, Nantou County, Taiwan. Hosui pears grafted on Niau Li tree seedlings had been planted in 1985 and trained as pergola trellises with 3 main branches. All vegetative shoots were weighed down in July and August 1992 by a cloth clip hung with a 30-cm piece of wire in order to force lateral floral bud formation. A complete micronutrient solution was applied as a foliar spray every 2 weeks between July and October. Shoot bending in summer was effective in promoting lateral bud formation at the end of the year, while postharvest fertilization and defruiting the canopy promoted some additional lateral bud formation. The estimated yield of fruits and scions was 11 and 0.6 t/ha, respectively. The quality of lateral floral buds produced in Mei-feng was not as high as that in Li-shan, Taiwan, or in Fukushima, Japan, but was acceptable to

 farmers who transgrafted [topworked?] the scions on Hengshan Li grown in lowland areas in the winter.
