Promotion of callus initiation, shoot regeneration and proliferation in Lisianthus.
The effects of plant growth regulators were examined in order to optimize the callus induction, regeneration, and proliferation of lisianthus (Eustoma grandiflorum). In vitro leaves provided the explants for callus induction. Explants were cultured on Murashige and Skoog (MS) medium with different concentrations of indole-3-acetic acid (IAA), 1-naphthaleneacetic acid (NAA), and 2,4-dichlorophen...
متن کاملApple Proliferation Phytoplasma
Introduetion Apple proliferation (AP) is one of the most economically important phytoplasmal diseases in Europe. It seriously impairs fruit size, yield, and vigor of the trees. AP was first reported in northern Italy (Rui et al., 1950). In the following decades, the occurrence of AP was reported from most European countries. Due to its transmissibility by grafting, the disease was initially tho...
متن کاملIdentification and molecular characterization of the phytoplasma associated with a lethal yellowing-type disease of coconut in Côte d’Ivoire
Coconut palms from the Grand-Lahou region of Côte d’Ivoire exhibiting lethal yellowing-like symptoms and infected by a phytoplasma were further tested for the characterization of the phytoplasma pathogen based on the 16S rRNA gene analysis. Nested PCR with phytoplasma universal and lethal yellowing-specific primers resulted in amplification of products of expected sizes from seven out of 17 sym...
متن کاملUsing Gibberellins to Prevent Leaf Yellowing in Cut Lilies
Hybrid lilies are excellent cut flowers due to the availability of flowers with various colors and shapes. Extensive inter-species hybridization has resulted in numerous cultivars, and many new cultivars are introduced to the market each year. While the vigor and reliability of the crop has improved over the years, what has not changed is that the postharvest quality of the cut stem is an impor...
متن کاملMolecular and symptom analyses of phytoplasma strains from lettuce reveal a diverse population.
ABSTRACT Epidemics of aster yellows in lettuce in Ohio are caused by at least seven distinct phytoplasma strains in the aster yellows (AY) group. Five of the strains are newly reported: AY-BW, AY-WB, AY-BD3, AY-SS, and AY-SG. All seven strains were characterized based on symptoms in aster and lettuce, and by polymerase chain reaction (PCR). Strain AY-BD2 (formerly 'Bolt') causes yellowing and l...
