“…Also seasonal effects were observed in the combinations with prefertilization barriers suggesting that stress conditions affected the pollen tube growth and the inhibition reaction. In lily and tulip a positive effect of high temperature in overcoming incongruity has been applied in interspecific combinations (Van Tuyl et al, 1982;Okazaki & Murakami, 1992). For Alstroemeria the optimal growing conditions are at a temperature between 15-180 C. Higher temperature can be seen as an environmental stress factor which may influence the pollen tube growth.…”

An early postfertilization ovule culture technique in Alstroemeria was described in which young ovules were cultured in vitro two days after pollination. This resulted in the direct production of seedlings in a normally incongruous cross combination. A histological study of the in vitro cultured ovules revealed the development of the embryo inside the ovule in the absence of normal endosperm. The in vivo grown ovules showed a total breakdown of the developing seed within four weeks after pollination due to a postfertilization barrier. This ovule culture technique was applied in a diallel cross of seven Alstroemeria species, five from Chile and two from Brazil. The selfings and the reciprocal crosses between the Brazilian species A. inodora and A. brasiliensis were congruous and gave seed set. The cross A. inodora × A. pelegrina gave viable seeds. In all other 39 combinations no viable seeds were harvested. In those cross combinations both pre-and postfertilization barriers were found. After early ovule culture hybrid plants were obtained in 27 of the 39 incongruous species combinations of the diallel.Abbreviations: DAP -days after pollination, MS medium -medium according to Murashige & Skoog (1962)

“…The species is an important ornamental flower and has been cultivated throughout the world. Although its cultivars have been used as a suitable plant material to study the SI reaction mechanism Peloquin, 1966, 1970;Li et al, 1996;Matsubara, 1973;Suzuki et al, 2001;Tezuka et al, 2007;van Tuyl et al, 1982), selfcompatible individuals and cultivars had never been discovered. Recently, Hiramatsu et al (2001a) revealed that genetic variability and divergence in L. longiflorum are very high, and that isozyme loci with a significant excess of homozygous genotypes frequently occur in some natural populations.…”

Lilium longiflorum is endemic to the islands of the Ryukyu Archipelago in Japan and to the eastern seacoasts and satellite islands of the mainland of Taiwan. The species is an important ornamental plant, and is cultivated throughout the world. Lilium longiflorum has long been regarded as a self-incompatible species but the existence of selfing in some natural populations was suggested by isozyme analysis in a previous study. To confirm the occurrence of self-compatible individuals and to clarify the evolutionary shift of floral traits associated with degree of self-compatibility in L. longiflorum by comparative analysis, we used 17 populations of L. longiflorum, and two populations of L. formosanum, the genetically closest species of L. longiflorum, covering the entire species distribution. Artificial self-pollination revealed that not all L. longiflorum individuals are self-incompatible and there is substantial quantitative variation of self-incompatibility among L. longiflorum individuals and populations. Self-compatible dominant populations allopatrically and independently evolved at the periphery of the species distribution area, the northern Ryukyu Archipelago and Taiwan. Increasing degree of selfcompatibility in L. longiflorum correlated with reduced corolla length, corolla width, corolla volume, and anther length for the Ryukyu Archipelago, in contrast to only reduced corolla width and volume for Taiwan. Approach between anther and stigma was not observed in any populations. Our data indicate that in the Ryukyu Archipelago increasing degree of self-compatibility evolved floral traits related to mating system evolution, to selfing, that does not depend on adjacency between anther and stigma position, but not in Taiwan.

“…A positive effect of high temperature in overcoming incompatibility and incongruity has been detected and applied in plant breeding by pollinating at high temperatures (Van Tuyl et al, 1982;Okazaki & Murakami, 1992). But present study shows grafting followed by A method for introducing Ocimum basilicum genes into Nicotiana tabacum 1073 pollination at low temperature (22-25°C) and high relative humidity (70-80%) could facilitate gene exchange and recombination at the interfamilial level and efficiently overcome barriers of sexual incompatibility.…”

Tobacco is an important cash crop in the world. However, the genetic basis is comparatively narrow among the modern Nicotiana tabacum cultivars, limiting its potential for quality improvement. To introduce genes conferring desirable chemical constituents from medicinal plants, a distant hybridization test was conducted between N. tabacum and Ocimum basilicum L. Seedlings of wild type Nicotiana sylvestris and N. tabacum cultivar 78-04 respectively acted as rootstock and scion. During the flowering season, hand pollination between 78-04 as pistillate parent and O. basilicum as pollen parent was carried out under 22-25°C temperature and 70-80% of relative humidity in the greenhouse. Seed sets of 55% were obtained in 78-04, and about 400 seeds per capsule were produced. But both non-grafted and self-grafted 78-04 plants rarely resulted in fruits by hand pollination and those obtained were without seed. Similar results were obtained in different material combination. The interfamilial F1 hybrids acquired showed distinct variation with various morphological characteristics, and their hybrid nature was confirmed by isozyme and random amplified polymorphic DNA (RAPD) analyses. This result indicated that pollination following grafting can facilitate gene exchange and recombination at the interfamilial level and efficiently overcome barriers of sexual incompatibility between N. tabacum and O. basilicum. Our research not only extends the genetic basis of tobacco but also will provide valuable germplasm for improvement of varieties.
