The life cycle and morphogenesis of the floral shoot of Paeonia lactiflora Pallas cv. Sarah Bernhardt were studied under Israeli conditions. The renewal buds for the following year originate on the underground crown, at the base of the annual stems. Bud emergence begins in early spring. Stems elongate rapidly and reach heights of 50–70 cm in 60–70 days.(More)
The inheritance of speed of germination and its genetic relations with seed dormancy was investigated in lisianthus (Eustoma grandiflorum). The study was based on data from parental, F1, BC1F1 and F2 generations of a cross between a normally germinating genotype (P1) and a chill-requiring genotype (P2). The mean post-chilling germination speed of P2 was(More)
The inheritance and linkage relationships of a leaf morphology gene of Matthiola incana were investigated. The allele for sinuate leaf shape, c, was found to be recessive to the allele for normal entire leaf, C. The c allele was tightly linked to the recessive allele for double flowering, s. The recombination frequency between the two loci was close to(More)
Accessions ofM. tricuspidata (L.) R. Br.,M. aspera Boiss. andMatthiola longipetala (Vent.) DC. were tested for their reaction to bacterial blight of stock (M. incana R. Br.), caused byXanthomonas campestris pv.incanae. Potted plants were sprayed with bacterial cell suspension, adjusted to 108 cells/ml. The tested accessions of the three species were found(More)
The inheritance of flowering time (FT) in a cross between early-flowering (P1) and late-flowering (P2) Matthiola incana genotypes, was investigated. The distribution of FT in F1, F2 and BC1 generations indicated an additive genetic control with partial dominance of earlines alleles, particularly with regard to double-flowered plants. Single-flowered plants(More)
The variation in growth characteristics among lisianthus (Eustoma grandiflorum Shinn.) genotypes was investigated. The genetic control of several growth parameters was studied by analysing parental, F1, BC1 and F2 populations. The parameters analysed were stem elongation rate (SE), stem diameter (SD), leaf width (LW), number of nodes (NN), node length (NL)(More)
