In vitro effects of gibberellic acid and sucrose concentration on
micropropagation of two elite sweet potato cultivars in Rwanda
- Abstract: The current study aimed at evaluating the effect of gibberellic acid (GA3) and sucrose on in vitro propagation of two elite sweet potato cultivars (Ukerewe and Gihingamukungu). Nodal explants from in vitro growing plantlets were harvested and cultured on Murashige and Skoog media supplemented with 2.5, 5, 10, 20 and 40 μM, GA3. In a separate experiment, sucrose was evaluated at 30, 60, 90, 1...

Influence of preservative solutions on vase life and postharvest
characteristics of rose (Rosa hybrid) cut flowers
- Abstract: The experiment was carried out to asses the influence of five preservative solutions (aluminium + ethanol, aluminium + sucrose, ethnol + sucrose, aluminium + ethanol + sucrose and water) and two rose cultivars (‘Red Sky’ and ‘Blizzard’). The scope of the study was to identify the best combination of preservative solutions on rose cultivars. The treatments were arranged in factorial combinati...

Genetic variation of 17 Y-chromosomal short tandem repeats (STRs) loci
from unrelated individuals in Iraq
- Abstract: Analysis of 17 Y chromosomal STR loci in a population sample of 400 unrelated male living in the middle and south of Iraq was done to evaluate allele frequencies and gene diversity for each Y-STR locus of the Y filer™ PCR amplification kit. The seventeen loci include DYS635, DYS437, DYS448, DYS456, DYS458, YGATA H4, DYS389I, DYS389II, DYS19, DYS391, DYS438, DYS390, DYS439, DYS392, DYS393, DY...

Effects of harvesting stage and storage duration on postharvest quality
and shelf life of sweet bell pepper (Capsicum annuum L.) varieties
under passive refrigeration system
- Abstract: A laboratory experiment was carried out to determine the effects of harvesting stages (0, 25, 50, 75 and 100% fruit colourations) and storage durations (0, 1, 2, 3 and 4 weeks) on physicochemical quality and shelf life of sweet pepper varieties (Telmo-Red and Velez-Yellow) under passive refrigeration system (PRS). The aim of the study was to identify the optimum stage of maturity at harvest ...

Diversity analysis of sugarcane genotypes by microsatellite (SSR) markers
- Abstract: Thirty (30) simple sequence repeat (SSR) primer pairs chosen randomly from the SSR primer collection were used to detect polymorphism in 17 sugarcane accessions. A total of 62 DNA fragments were generated by the 30 primers with an average of about 2.14 bands per primer. Bands that a primer yielded in the study ranged from 1 to 4. The genetic distances for SSR data using 17 sugarcane accessio...

Micropropagation of the Indian Birthwort Arsitolochia indica L.
- Abstract: Aristolochia indica L. is a medicinal woody perennial climber plant of immense pharmaceutical value. The species is endangered with possible extinction due to its indiscriminate harvesting as raw material for pharmaceutical industry, to manufacture drugs against cholera, inflammation, biliousness, dry cough and snake bite. A rigorous attempt has been made for development of in vitro propagat...

A quick bud breaking response of a surface model for rapid clonal
propagation in Centella asiatica (L.)
- Abstract: Present investigation was planned to evaluate time period of bud breaking in Centella asiatica with different concentration of plant growth regulators, a medicinal herb distributed throughout the worldwide. For the study, concentrations were designed for response surface model describing bud breaking growth in optimum conditions. A combination of BAP (2 mg/L) + gibberellic acid (GA3, 0.5 mg/...

Molecular characterisation of two cichlids populations (Tilapia guineensis
and Sarotherodon melanotheron) from different water bodies in Lagos State,
Nigeria
- Abstract: This study used random amplified polymerase DNA technique (RAPD) to characterize two populations of cichlids species Tilapia guineensis and Sarotherodon melanotheron from selected two water bodies in Lagos using molecular approach. Ten samples of each S. melanotheron and T. guineensis with standard length value ranging between 8.4 and 17.2 cm and their weight ranging between 26.1 to 13...

Micropropagation of Litsea glutinosa (Lour) C.B
- Abstract: Litsea glutinosa (Lour) C.B (Hindi: Maida lakri) is a medicinal plant of immense pharmaceutical value. The species is critically endangered due to its indiscriminate collection as raw material for pharmaceutical industry, where it is used for manufacturing drugs for pain, arousing sexual power and in treatment of diarrhea and dysentery etc. An attempt has been made for developmen...

Cell growth curves for different cell lines and their relationship with
biological activities
- Abstract: The cellular-growth curves for distinct cell lines (tumor and non-tumor) were established, evaluating the population of doubling time (DT) and maximum growth rate (µmax). These curves define the growth characteristics for each cell line; they allow determination of the best time range for evaluating the effects of some biological compounds. Subsequently, the biological activities of th...
