Isoelectric focusing and native polyacrylamide gel electrophoresis of S-ribonucleases; PCR analyses of S-RNase and S-haplotype-specific F-box genes as well as DNA sequencing were carried out to survey the self-(in)compatibility allele pool and to uncover the nature of self-compatibility in peach. Studies on some aspects of floral biology in chillies. The field is broad and interdisciplinary and involves research requiring expertise from multiple disciplines that can include botany, ethology, biochemistry, entomology and a range of analytical techniques. Genetics and Breeding of Capsicum and Eggplant, Avignon, Most important commercial cultivars carry the same S-allele and are in a homozygote state. The majority of the varieties belonged to the last two groups, nevertheless. The techniques employed include those of physics, chemistry, physiology, psychology, genetics, and ecology, and so constitute a broad training in biology that may be useful and acceptable in other fields. The number of flushes and their importance are determined by cultivar characteristics, crop load and climate. floral biology of temperate fruit crop 1.

Floral biology of muskmelon. A number of varieties/hybrids have been bred in chilli in the recent past, but the yield and quality plateau could not be broken simultaneously. The reason may lie in the fact that most peach cultivars are self-compatible (Cullinan, 1937; ... Cultivars used in this study were previously characterized as being self-and cross-compatible (Miller et al., 1989; ResearchGate has not been able to resolve any references for this publication.
