“…In general growth regulators treatments affected the constituents of marjoram essential oil. These results were in agreement with those obtained by Meawad et al (1984) who stated that B-9 [daminozide] at 50-500 ppm were generally the best treatments for increasing essential oil yield and chamazylene percentage in the oil of Matricaria chamomilla plant. Mohandass and Sampath (1985) on Pelargonium graveolens, found that the best results of essential oil yield and quality were obtained with Alar [daminozide] at 1000 ppm.…”

The aim of this research was to study the effect of foliar spray with BA and B-9 on essential oil production and chemical composition of marjoram plant. The plants were sprayed with BA at the rates of 50, 100 and 150 ppm, while B-9 at the rates of 500, 1000 and 2000 ppm in addition to control treatment which sprayed with distilled water. The obtained results can be summarized as follows: BA at the rates of 50, 100 and 150 ppm or B-9 at the rates of 500, 1000 and 2000 ppm increased all recorded parameters as compared to control treatment with significant differences in most cases during the two seasons. In the first season, the highest value of essential oil percentage was produced with B-9 at 1000 ppm, while the highest values of essential oil yield were obtained with BA at 50, 150 ppm and with B-9 at 1000 ppm treatments. In the second season the highest values of essential oil percentage and essential oil yield were produced with BA at 50 and 100 ppm, respectively. The major essential oil components were linalyl acetate and terpinen-4-ol. The highest percentage of linalyl acetate was detected in the oil of the plants sprayed with B-9 at 1000 ppm in the two seasons, while in the first season, the highest percentage of terpinen-4-ol was found in oil of the plants sprayed with B-9 at 500 ppm as well as the highest percentage of terpinen-4-ol in the second season was produced from control treatment followed by B-9 at 500 ppm. In the first season, the highest values of chlorophyll a, b and carotenoids were produced with BA at 50 ppm, B-9 at 2000 and 500 ppm, respectively. While in the second season, the highest values of chlorophyll a, b and carotenoids were obtained from B-9 at 2000 ppm, BA at 150 ppm and BA at 150 ppm, respectively. The highest values of total carbohydrates percentage were resulted in B-9 at 2000 ppm in the two seasons. In the first season, the highest total seasonal yield of essential oil was obtained from B-9 at 1000 ppm, while in the second season, the highest value was produced from BA at 100 ppm. Generally in combined statistical analysis B-9 at 1000 ppm was the most effective treatment in increasing total seasonal yield of essential oil. The lowest values of all recorded parameters were produced from the control plants in the two seasons. Different cuts as general mean had a significant effect on all recorded parameters in the two seasons. The highest values of essential oil percentage, chlorophyll a, b and carotenoids were produced from the third cut in the two seasons. Also, the highest values of total carbohydrates percentage were produced from the second cut and third cut in the first and second seasons, respectively. The highest values of essential oil yield were obtained from the third cut and fourth cut in the first and second seasons, respectively. The interaction between the growth regulators (BA or B-9) and the cuts increased all recorded parameters as compared with the control in any cut during the two seasons with significant differences in most cases.

“…Also foliar spray by diminozide (B-9) on some medicinal and aromatic plants had a clear effect on increasing the growth and yield. This conclusion was stated by many scientists, Eid and Rofaeel (1980) on Pelargonium graveolens , El-Sharkawy (1981) on Majorana hortensis, Meawad et al (1984) on Matricaria chamomilla, Mohandass and Sampath (1985) on Pelargonium graveolens, Abdellah et al (1986) on Calendula officinalis, Shedeed et al (1990) on Ocimum basilicum, Suparna et al (1993) on Gloriosa superba, Singh (2003) on Calendula officinalis, Koodziej (2005) on American ginseng and Barbara et al (2006) on American ginseng. On the other hand Figueiredo et al (2006) on Cymbopogon citratus,found the opposite response with B-9.…”

The aim of this research was to study the effect of foliar spray with BA and B-9 on the growth and yield of marjoram plant. The plants were sprayed with BA at the rates of 50, 100 and 150 ppm, and B-9 at the rates of 500, 1000 and 2000 ppm in addition to control treatment which sprayed with distilled water. The obtained results can be summarized as follows: All concentrations of BA or B-9 increased all recorded parameters as compared with the control treatment with significant differences in most cases during the two seasons. In the first season, the highest values of plant height, fresh weight of herb, dry weight of herb, dry weight of leaves and flowering tops, total seasonal yield of dry weight of herb and total seasonal yield of dry weight of leaves and flowering tops were produced from using BA at 150 ppm, while the highest dry weight of stems was obtained from B-9 at 2000 ppm. The lowest values of all recorded characters were resulted in control treatment. In the second season, the highest values of plant height, dry weight of herb and total seasonal yield of dry weight of herb were produced from BA at 100 ppm, whereas the highest values of fresh weight of herb and dry weight of stems were obtained from BA at 150 ppm. Also the highest values of dry weight of leaves and flowering tops and total seasonal yield of dry weight of leaves and flowering tops were resulted in B-9 at 500 ppm. Generally, in combined analysis BA at 150 ppm was the most effective treatment in increasing total seasonal yield of dry weight of herb and total seasonal yield of dry weight leaves and flowering tops. Different cuts as a general mean had a significant effect on all recorded parameters in the two seasons. In the first season, the highest values of plant height and fresh weight of herb were produced from the second cut. Also, the highest values of dry weight of herb, dry weight of leaves and flowering tops and dry weight of stems were produced from the third cut. In the second season, the highest values of fresh weight of herb, dry weight of herb, dry weight of leaves and flowering tops and dry weight of stems were obtained from fourth cut, whereas the highest value of plant height was produced from the first cut. The interaction between the growth regulators (BA or B-9) and the different cuts increased all recorded parameters as compared with the control in any cut during the two seasons with significant differences in most cases.
