For the ornamental crop Gerbera hybrida, breeding at the moment is done using conventional methods. As this has drawbacks in breeding speed and efficiency, especially for complex traits like disease resistance, we set out to develop genomic resources. The leaf and flower bud transcriptomes of four parents, used to generate two gerbera populations, were sequenced using Illumina paired-end sequen...
Despite the differences in flower form, the underlying mechanism in determining the identity of floral organs is largely conserved among different angiosperms, but the details of how the functions of A, B, and C are specified varies greatly among plant species. Here, we report functional analysis of a Gerbera MADS box gene, GRCD1, which is orthologous to AGL2-like MADS box genes. Members of thi...
ABSTRACT Gerbera (Gerbera jamesonii Bolus ex Hook. F.; Asteraceae), is one of the most economically important ornamental plants due to its aesthetic value. In present study, we established a micropropagation method for large-scale production quality planting material gerbera ‘Pink Melody’. Eighty-six percent capitulum explants produced adventitious shoots (15.44 ± 0.34 per capitulum) on Murashi...
THE application of insecticides is often necessary in greenhouse crop production to prevent damage from insect pests that could render the plants unsalable. However, pesticide usage can lead to toxicity issues, which may adversely affect plant growth and development. It seems plausible that applications of foliar insecticides could adversely affect photosynthesis by clogging, or at least partia...
Studies on cut flowers have occurred, for improving their quality is the main priority. One of top 10 in world, gerbera, or Transvaal daisy (Gerbera jamesonii Hook), a flowering plant. The presented study aimed to investigate effect genotypes, storage duration, and interactions flower – daisy. Two cultivars Gerbera (sweet smile sweet surprise) four durations underwent examination various parame...
Scape bending disorder is the most important factor affecting postharvest loss of gerbera cut flowers. One of the ultimate reasons for gerbera stem bending is lignin, with deformation structural functions and defensive mechanisms. This postharvest experiment was conducted to evaluate the role of phenylalanine ammonia lyase (PAL) and peroxidase (POD) enzymes activity in stem bending of two gerbe...
An attempt was made to evaluate the utility of a method which employs semi-specific PCR using partially specific primers for the coding sequence (ET) at the exon-intron contact and of the RAPD method to identify eight Polish cultivars of gerbera. It was demonstrated that the PCR method which employs semi-specific primers is as simple and economical as the RAPD method, simultaneously the images ...
The presence of plant-parasitic nematodes causing crop loss every year had been overlooked in the existing fruits, vegetables and flowers cultivation system Bangladesh. Therefore, study was conducted to isolate identify plantparasitic from soil infected plant-parts fruits (banana, orange), (pointed gourd, tomato brinjal) flower (gerbera) districts Jashore, Jhenaidah, Gazipur Sylhet during 2017-...
An in vitro mass propagation protocol was developed for Gerbera (Gerbera jamesonii Bolus) var. orange using flower bud explants. The young (7 days) explants were found to be suitable culture and highest (100%) callus induction obtained MS medium supplemented with 5.0 mg/l BAP 1.0 NAA. maximum shoot regeneration (95%) the number of shoots (10) observed 6.0 0.3 multiplication frequency (60) only ...
A major component of the evaluation of biological control agents is the study and comparison of their biology, including the reproductive mode. In hymenopteran parasitoids, reproductive modes include thelytoky and arrhenotoky. Since a thelytokous population produces only females, it is assumed that they may be better suited for biological control than an arrhenotokous population. Here we compar...
