RESEARCH CONCENING THE INFLUENCE OF CULTURE SUBSTRATE ON THE MAIN CHARACTERISTICS OF TUBEROSE

摘要

Tuberoses is known for its fragrance and are among the most important ornamental flowers grown mainly due the long flowering period, which is an important aspect whether grown as cut flowers or landscaping. The purpose of this study was to improve the cultivation methodology of the species Polyanthes tuberosa, by using easily accessible, cheap substrates with influence on morphological, ornamental and production characteristics. The research was carried out in 2017 at the University of Agricultural Sciences and Veterinary Medicine of Cluj-Napoca. The experience was bifactorial and watched the influence of some culture substrates (garden soil, 50% peat + 50% garden soil, 50% sand + 50% garden soil and 50% manure + 50% garden soil), on the main decorative morphological characteristics of the 'Perla' tuberose variety. Following the interpretation of the results by the LSD test (variance analysis) it is recommended to use the culture substrate formed by peat or manure + garden soil (1:1) and bulbs with a larger diameter.
