ISHS Acta Horticulturae 379: International Symposium on Quality of Fruit and Vegetables: Influence of Pre- and Post- Harvest Factors and Technology

EFFECT OF A LONG CHAIN ALIPHATIC ALCOHOL (TRIACONTANOL) ON GROWTH AND YIELD OF DIFFERENT HORTICULTURAL CROPS

Authors:   C. Kapitsimadi, S.A. Vioryl
Abstract:
The influence of triacontanol on growth and yield was studied in tomato, sweet pepper, sugar beet, cotton, tobacco and potato plants. Three foliar sprays of triacontanol were applied to all the crops, starting at the early stages of plant growth.

In tomato and sweet pepper, plant height and leaf number were higher in the treated plants than the control ones. The mean cumulative yield per treated plant was significantly higher than the control ones. In sugar beet plants treated with triacontanol, the leaf number and the mean root weight were significantly bigger than the control ones. In tobacco plants the mean leaf number per plant was 11% bigger for treated plants than the control ones, whereas the mean leaf dry weight was 24% more than the control plants. In potato and cotton plants the yield per plant was significantly higher for the treated plants.
