QUALITY OF FRENCH-FRIES OF 37 POTATO CULTIVARS IN CONDITIONS OF APPLICATION OF GROWTH REGULATORS MIVAL AND POTEITIN
Barbara Sawicka, Maria Mikos-Bielak
ABSTRACT
Use of growth regulators at potato cultivation and its effect on subsequent french-fries quality. The qualitative analyses of french-fries were based on tuber samples from a field experiment carried out on sandy-loamy soil in 1990-1992 in Parczew, Biała Podlaska Province. The experiment was set up with randomized subblocks in three replications. The subblocks of 1st row were made by the growth regulators: a) Mival concentration 500 mg × l-1 water; b) Poteitin concentration 10 mg × l-1 water; c) the control with distilled water. The growth regulators were applied onto the tubers in a spray form just before the planting. A factor of 2nd row was made by 37 potato cultivars out of all the earliness groups. Regulator Mival contributed to french-fries taste and flavour improvement in the years of a warm and dry potato vegetative period and Poteitin preparation has contributed significantly to improve french-fries consistency. Both growth regulators concurred to i
