Fifteen spineless prickly pear cultivars (Opuntia ficus-indica) were evaluated for three successive seasons at the University of Pretoria Research Farm. Yields were recorded and external and internal fruit quality factors were identified and considered. Following this investigation, minimum standards were suggested and the cultivars under review were compared. The cultivars Morado, Algerian, Fusicaulis van Heerden, Fresno, Mexican and Nudosa met all or most of the standards set. It is concluded that for fresh fruit production these cultivars are best suited for planting in the Pretoria region and in areas with similar climatic conditions.

The Impact

Prickly pear (Opuntia ficus-indica (L.) Mill. 1768) is cultivated in several dry and semi-dry areas of the world to produce fresh fruit, bioenergy, cosmetics, medicine, and forage. One of the main production constraints is the presence of many seeds within the fruit, which can negatively influence both the fresh-fruit market price and industrial transformation processes. In this study, different gibberellic acid (GA3) concentrations were tested for their ability to produce well-formed and seedless fruits. Different application methods (injection and spraying) and concentrations of GA3 (0, 100, 200, 250, and 500 ppm) combined with floral-bud emasculation were applied to a commercial plantation in southern Italy to evaluate their effects on the weight, length, and diameter of the fruits, total seed number, hard-coated viable seed number, and seed weight per fruit. The results indicated that the application of 500 ppm GA3 sprayed on emasculated floral buds was the most effective method for reducing seed numbers of prickly pear fruits (−46.0%). The injection method resulted in a very low number of seeds (−50.7%) but produced unmarketable fruit. Observed trends suggest the need to investigate the impact of higher GA3 concentrations and the applicability of a maximum threshold. Further studies are needed to increase our understanding of the physiological effects of the gibberellic acid pathway through productive tissue in terms of organoleptic and fruit quality.

Pear Cactus

Productivity of irrigated prickly pear cactus [Opuntia ficus-indica (L.) Miller] was studied over 3 years in central Chile using two planting densities. A low-density planting (0.25 plants/m2), traditionally favored for fruit production, had maximal fruit productivity in the 2nd year (6 Mg dry weight/ha per year). A high-density planting (24 plants/m2), which assured almost full interception of incident solar radiation, led to an extremely high shoot dry-weight productivity (50 Mg·ha-1·year-1) in the 2nd year and maximal fruit productivity (6 Mg·ha-1·year-1) in the 3rd year. Cladode dry weight tended to increase with cladode surface area. However, fruit production did not occur until the dry weight per cladode exceeded the minimum dry weight for a particular cladode surface area by at least 33 g. The year-to-year variation in fruit production apparently reflected variations in such excess dry weight and, hence, in the storage reserves of individual cladodes.

The Impact

This study seeks to address the impact of service quality affecting international student's satisfaction towards loyalty tothe Universiti Tun Hussein Onn Malaysia(UTHM). The aim of thestudy is to develop relationship between service quality factor and loyalty to the university from the international students’ perspectives. The study adopted quantitative approach where data was collected through questionnaire survey and analysed statistically. A total of 246 responses were received and found to be valid. The model was developed and analysed using AMOS-SEM software. Confirmatory factor analysis (CFA) function of the software was to assessed the measurement models and found that all the models achieved goodness of fit. Then path analysis function was used to assessed structural model and found that service qualityfactors have a significant effect on the students’ satisfaction and thus affecting the loyaltyto the university. Hopefully the outcome form this study will benefit the university in providing services especially to the international students.

Plant Parts

Opuntia ficus-indica(the cactus or prickly pear) is a cactus belonging to the Opuntiae family. Several Opuntiae plant parts have been used in traditional Moroccan medicine. In this study, we investigated its most common use as an analgesic. An ethnobotanical study ofOpuntia ficus-indicawas first conducted in 10 areas in Morocco. Extracts fromOpuntia ficus-indicacladodes were obtained using a decoction method and its analgesic activity in mice was investigated by the hot plate and tail flick methods. Cladode extracts had significant (p<0.05) analgesic activity at intraperitoneal doses of 300, 500, and 1000 mg/kg body weight. Both methods revealed significantly increased latency at all three doses (p<0.05) compared to controls. These data suggest that the traditional use of this plant as an analgesic is valid; in fact, perhaps it may be a centrally-acting analgesic.

Background: When midwives are not treated with respect and their professional competencies are not recognised, their professional dignity is violated. Objective: This study explored and described how the professional dignity of midwives in the selected hospital can be enhanced based on their experiences. Research design: A descriptive phenomenological research design was used with in-depth interviews conducted with 15 purposely selected midwives. Ethical considerations: The Faculty of Health Sciences Research Ethics Committee of the University of Pretoria approved the study. The research was conducted in an academic tertiary hospital with voluntary participants. Findings: To dignify midwives it is essential to enhance the following: ‘to acknowledge the capabilities of midwives’, ‘to appreciate interventions of midwives’, ‘to perceive midwives as equal health team members’, ‘to invest in midwives’, ‘to enhance collegiality’, ‘to be cared for by management’ and ‘to create conducive environments’. Conclusion: The professional dignity of midwives is determined by their own perspectives of the contribution that they make to the optimal care of patients, the respect that they get from others and the support that hospital management gives them. With support and care, midwives’ professional dignity is enhanced. Midwives will strive to render excellent services as well as increasing their commitment.

Abstract O. ficus-indica is highly valued as a fruit-producing cactus, also yielding 'leaves' that are used as a vegetable and browsed by livestock. It has been introduced widely from its native Mexico to almost all countries where the climate is suitable. The fruit is very rich in vitamin C and is exploited commercially in many areas. Many countries, especially in Asia, have recently established large-scale commercial plantations. However, O. ficus-indica, like several other species of Opuntia, have been known to spread and become invasive weeds. Historical records, however, appear to indicate a time-lag of about 100 years between introduction and the beginnings of invasive spread thus the actual risk may be low.

The paper presents the results of evaluating the efficiency of feed rations offered to broilers of the Arbor Acres cross, formed taking into account the climatic, geochemical conditions of Central Africa and its native food flora. The study was conducted on the basis of an experimental farm at the University of N’Djamena, the Republic of Chad. In the experiment, the authors used five formulas of feed rations, which are currently used by farms in the Republic of Chad for growing broiler chickens. They mainly contain locally availble ingredients. To increase the resistance of the poultry organism to unfavorable environmental factors, the chickens of the control and experimental groups were given “TETRACOLIVIT” and “AMIN’TOTAL” vitamins. The efficiency of feed rations was evaluated by determining the age dynamics of live weight, average weekly gains in live weight and blood biochemical parameters of broiler chickens of the Arbor Acres cross from 1 to 42 days of life. The formula of feed ration No. 1 proved to be the most effective in terms of the cross productivity.
