Hand Pinching increased branching and fruit yield. At first harvest dikegulac-sodium at 50 ppm increased fruit yield compared to the control. However, dikegulac sodium at 100 ppm reduced fruit yield initially but had no effect on fruit yield at 2-4th harvests. Digkegulac-sodium, Gibberellic acid, and hand pinching did not affect fruit length at third and fourth harvests. However, first and second harvests dikegulac sodium reduced fruit length whereas GA3 had no effect. None of the treatments affected fruit width. Dikegulac sodium and Hand pinching increased the number of branches after three weeks, but GA3 did not. At 8 weeks after treatment dikegulac solution at 50 ppm and 100 ppm increased branching compared to the control. GA3 at 100 ppm also increased branching. The remaining treatment had no effect. GA3 at 50 ppm increased juice pH comparing to the control. None of treatments affected sugar content at regardless of harvest date.

The effect of the time of application of Gibberellic Acid (GA3) and Lipo-Chitin Oligosaccharides (LCOs) on annual production of globe artichoke (Cynara scolymus L.) cultivars 'Imperial Star' and 'Green Globe' was studied in 2000 and 2001. In order for flowering to occur plants must undergo a period of vernalization. In 2000, plants received 54 chilling (vernalizing) hours, an amount sufficient to induce flowering in 100% of the Imperial star and 25% of the Green Globe control plants. Applications of 25ppm GA3 at the 6 and 10-leaf stage reduced the time to flowering by 11 days, increased uniformity of flower bud production, and also increased yield of Imperial Star. GA3 had no significant effect on Green Globe plants. LCO fraction C (an identified and collected nod factor peak in retention time of 32.56 minutes) had minimal effect on growth and development for both cultivars in 2000. In 2001 plants received no vernalizing temperatures and in addition were exposed to 89 hours of temperatures greater than 32°C which could devernalize the plants. (Abstract shortened by UMI.)

Magister Scientiae (Biodiversity and Conservation Biology) - MSc (Biodiv and Cons Biol) / Randomized block experiments were conducted to examine the putative amelioratory effects of kinetin or gibberellic acid at concentrations (0, 4, 12.5, 40, and 125 μM) in Erucastrum strigosum plants subjected to a salinity series (0, 100, 200, 300, and 400 mM NaCl) in the greenhouse. When the highest salinity concentration (increased stepwise) was reached, growth effects in relation to water and cation content of the plants were evaluated. Growth and water content were reduced progressively with salinity treatments. Na+ concentration accumulated with salinity treatments to levels that were much higher than that of other cations (K+, Ca2+ and Mg2+) in both organs. However, it is noteworthy that Na+ distribution was more in shoots than in roots. In kinetin treated plants, shoot growth decreased whilst root growth increased with moderate hormonal treatments.

Submitted in partial compliance with the requirements of the Master’s Degree in Technology: Homoeopathy, Durban University of Technology, Durban, South Africa, 2016. / Aim The aim of this controlled, experimental study was to compare the biological activity of various homoeopathic potencies of gibberellic acid manufactured radionically (AMS transfer device) and conventionally (GHP) in terms of their respective influence on germination rate and seedling development of barley seeds; all the respective results being contrasted against those produced by the distilled water control. Methodology The research was completed by employing quantitative research techniques and followed true experimental design. Homoeopathically (Hahnemannian) prepared gibberellic acid followed the manufacturing guidelines of method 5a involving liquid preparations, as specified in the German Homoeopathic pharmacopoeia (GHP) (Benyunes 2005). A second radionic ‘equivalent’ version of each of the Hahnemannian potencies was manufactured using the ‘AMS wave transfer’ device. Four sources of data were collected namely, germination count and rate, seedling development (root length), seedling dry mass, and number of seeds with measurable roots. All the data was collected and documented on a data collection sheet using Microsoft Excel. All the data was statistically analysed and subjected to analysis of variance (ANOVA) using GenStat Version 14 (VSN International, UK) at the 5% level of significance. The statistical data was used to produce a comparison between the different remedies and distilled water. Results All of the remedy treatment groups (Radionic 200c, Hahnemannian 200cH, Radionic 4c and Hahnemannian 4cH) displayed suppressive effects (to certain extents respectively ) on seed growth and development in comparison to the control group (distilled water). The control group displayed greater seedling development in comparison to all remedy treatment groups which was most evident in the average root lengths and high vigour seed lot root lengths having longer roots than all remedy treatment groups. The control group also displayed a higher number of seeds with measurable roots compared to all the remedy treatment groups in both total number of seeds and in the seeds accounted for in the high vigour lots. This suggests that all Homoeopathic remedies irrespective of potency or manufacture method (Radionic or Hahnemmanian) had similar suppressive effects on root growth and seedling development and this suppressive effect was in turn not evident in the control group. Conclusion The experiment results suggest that radionically manufactured homoeopathic remedies (AMS wave transfer device) have similar biological effects (suppressive effects) to the equivalent Hahnemannian manufactured homoeopathic remedies, although further research in this field is necessary to confirm these findings the results from this study are supportive of the use of radionically prepared remedies in homoeopathic practice. / M
