Abstract

Lycorisの種間雑種を作出するために, 交雑後に花茎を植物体から切り離し, 水に生けた状態に置くことによって, 8通りの種間交雑組み合わせのうち7組み合わせで植物体を得ることができた.また, Lycoris 3種を用いて種間交雑を行った後, 受粉後柱頭に2%NAA処理を施すことによって, 着果率と果実当たりの種子数を増加させ, 結果として交雑個体の獲得率を著しく高められることが明らかになった.

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 combinations 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. Thus, the hormone treatment improved the efficiency of obtaining interspecific hybrids with Lycoris.
