Assessment of the influence of external factors on the growth of roots and bulb scales of some varieties of Lilium L.

Abstract

Lily varieties are a plant that grows in moderate humidity and moderate temperature. Therefore, they are not widely grown in Uzbekistan. As with other ornamental bulbous plants, Lilies have been developed in various ways, and it is important to learn which methods work best in which environment. Lily varieties are propagated by bulbs, bulbs, cuttings, leaves, small buds on the stem (bulbous) and seeds. These methods of reproduction allow selection of varieties suitable for a specific environment by determining the degree of influence of various external environmental factors along with substrates. Empoli, Honeymoon, Purple price cultivars belonging to the OT hybrids group showed higher values of Empoli cultivar than other cultivars when studying the effect of temperature and humidity of the sphagnum substrate on the rooting and length of the pods isolated from onion heads. Optimum humidity and temperature indicators of the substrate with sphagnum were determined for all studied varieties.
