“…Triploid L. lancifolium × diploid L. lancifolium did not produce seeds in this study or in the study by Noda (1986). Lilium species often show gametophytic selfincompatibility (Ichimura and Yamamoto, 1992;Sakazono et al, 2012), and self-incompatibility is one possible reason for the sterility in this cross combination, which was supported by the results that fertile seeds were obtained by a cut-style pollination. …”

Lilium leichtlinii (2n = 2x = 24) is the most commercially cultivated edible lily in Japan, although viral and fungal diseases are severe problems. Triploid L. lancifolium (2n = 3x = 36), the bulbs of which are also edible, adapts well to the climate in Japan, and feral triploid L. lancifolium plants are often seen along roadsides and in croplands. Thus, triploid L. lancifolium is an important genetic resource for edible lilies, but it develops many bulbils (aerial bulbs) on leaf axils. Bulbil formation is undesirable for edible lilies because bulbils can compete for photosynthate with bulbs, which limits the use of triploid L. lancifolium in commercial production. Edible lily cultivars have been bred by intraspecific crosses within L. leichtlinii, although interspecific hybridization, which increases the level of genetic variation, is the major technique used to breed floricultural lily cultivars. In this study, interspecific-hybrid plants were developed by crossing triploid L. lancifolium and L. leichtlinii, and their characteristics, including bulbil formation ability, were evaluated. The crosses of triploid L. lancifolium × L. leichtlinii developed aneuploid plants, of which the chromosome number ranged from 26 to 34. Bulbil formation ability was continuously distributed in the F 1 offspring, although 86% of F 1 plants did not develop bulbils, indicating that many aneuploid plants without bulbils are developed by this cross combination. The plants harboring abnormal anthers were segregated in the hybrids. In addition, pollen germination in the F 1 hybrids was lower than 20%, and 85% of the hybrids exhibited no pollen germination. However, abnormal anther morphology and low pollen fertility should not be major problems for edible lily production because bulbs are the main commercial output. These results indicate that interspecific hybridization between triploid L. lancifolium and L. leichtlinii has the potential to develop elite edible lily cultivars.

“…1993;Wu et al 1995). Among these substances arc carbohydrates which are metabo lised in the pistil after pollination and are assumed to supply energy for the growing pollen lubes (Herrero and Dickinson 1979;lehimura and Yamamoto 1992;Knox 19K4). Once pollen germinates after pollination, the pol len lubes grow very rapidly.…”

Induced ADH gene expression and enzyme activity in pollinated pistils of Solanum tuberosum

The regulation of alcohol dehydrogenase (ADH) in relation to in vivo pollen lube growth ol' Sola tium tuberosum was investigated. Adh gene expression as well as ADH enzyme activity were induced in pollinated pistils. The induced ADH isozyme in pollinated pistils is not present in pollen or anthers. The same ADH isozyme is induced in leaves submerged in water. The signifi cance of the induction of ADH activity for pollen tube growth is discussed.
