Abstract
Lycoris albiflora, L. aurea, L. radiata and L. sanguinea were cross-bred to yield 8 interspecific combinations. When the scapes were cut at their base after crossing and kept in water, a few interspecific hybrids from 7 combi nations were obtained. The percentages of fruit set and the number of seeds per capsule were increased by applying 2% Naphthaleneacetic Acid (NAA) on the stigma after pollination in three interspecific hybrids of Lycoris. Thu s, the: hormone treatment improved the efficiency of obtaining interspecifi c hybrids with Lycoris.
