Chrysanthemum is one of important ornamentals in Indonesia and it ranks in the first quantity of cut flower marketed every year. In most cases, the low productivity is still a constraint for the traditional growers to make production process profitable. Several problems revealed in chrysanthemum production were investigated. The study dealt with the effect of two types of plastic house constructions, irrigation frequency, and leaf detachment on the growth and development of chrysanthemum. The experiment was conducted at Segunung, Indonesian Ornamental Plants Research Institute during the dry season of 2005. A nested design with six replications was used. The results showed that plants grown in wood-constructed plastic house had better growth performance and flower quality than those under bamboo plastic house. Longer stem and higher plant fresh weight with more flowers and longer life span were also observed on chrysanthemum irrigated four times per week than those irrigated twice per week. Leaf removal often practiced by the growers is no longer recommended, since the number of leaves on the plant influenced all parameters observed. The more leaves were detached, the more negative impacts on plant growth were found.

Passionflower is a member of Passifloraceae family, it can be used as medicinal and ornamental plants in addition to its consumption as fruit in the world. Guava (Psidium guajava L.) fruits, which has a rich nutrient content, are consumed both fresh and processed. Passionfruit and guava plants, which can only be cultivated in temperate southern coasts in our country, have gained commercial importance because of the fruits' export potential, high medical importance and nutrient. This study was carried out to determine the effects of some bioactivator applications on the criteria of sapling growth and development of passionflower and guava plants. The experiment was conducted between 2018-2019 under greenhouse conditions. Saplings obtained from seed germination in Akdeniz University Faculty of Agriculture Research and Experiment Area were used as plant material. 3 different commercial preparations called Messenger, Crop-set and ISR-2000 were used as bioactivators. Plant height (cm), stem diameter (mm) and number of leaves (number / plant) were measured weekly, in order to determine the effect of the applications on the growth and development of saplings. At the end of the study, it was determined that the highest average plant height (10.17 cm), stem diameter (13.53 mm) were obtained in ISR-2000 application. The highest average plant height (11.93 cm), stem diameter (16.44 mm) and number of leaves (9.07 units / plant) were obtained from Messenger application in guava plant. When the results obtained are evaluated, it is recommended that ISR-2000 bioactivator can be applied in passionflower sapling cultivation and Messenger bioactivator can be applied for guava sapling cultivation.

This study was aimed at assessing the growth and production of celery plants grown with various compositions of N,P and K fertilizer and compost. The study was done at the Trial Farm of Faculty of Agriculture, Djuanda University, Bogor fiom September to November 2015. A completely randomized design with two factors was used. The factors consisted of compost rate and N,P and K fertilizer rate. Compost was given in four levels, namely no compost (0% R), 26.3% gcompost/plant (50% R), 52.5 g compost/plant (100% R), and 78.7 g compost/plant (150% R). N, P and K fertilizer was given in five levels, namely no fertilizer (0% R), 4 g Urea, 0.3 g SP-36, 0.2 g KCl (25% R), 0.9 g Urea, 0.6 g SP-36, 0.4 g KCI (50% R), 1.3 g Urea, 0.8 g SP-36, 0.6 g KCl (75% R), and 1.7 g Urea, 1.1 g SP-36, 0.8 g KCl (100% R). All fertilizers were administered gradually at the time of planting and 2 weeks after planting. Three replicates were allocated into each treatment making up 60 experimental units. Results showed that celery plants given synthetic fertilizer at 100% R had higher plant height, number of leaves, number of seedlings, harvest fresh weight (g), saleable fresh weight (g), root biomass (g), and root dry weight (g) than those treated with no fertilizer (0% R). Plants treated with 150% compost had higher plant height, number of leaves, harvest fresh weight (g), saleable fresh weight (g), root length (cm), and root dry weight (g) than those treated with no fertilizer (0% R). Thus the best celery growth and production in this study was obtained on plant 150% R compost   and 100% R synthetic fertilizer nourished.Key words: celery, compost, N, P, K fertilizer, harvest flesh weight

The experiment was conducted to investigate the combined effect of different plant growth regulators and charcoal supplementation in MS medium on growth and development of plantlets regenerated from protocorm like bodies (PLBs) of hybrid orchid. The combination of BAP + NAA, BAP + IAA, BAP + IBA, and IAA + IBA at different concentrations with charcoal supplementation was studied. The result revealed that the use of different growth regulators had significant effect on different parameters studied. The maximum weight of PLBs (5.123 g) was obtained from the combination of BAP + IBA at 1.0 mg/l each. The highest shoot height (3.239 cm) and maximum number of rooted plantlets (4.473) was obtained from 1.0 mg/l each of BAP + NAA combination. The maximum number of leaves (3.490) and the maximum length of leaves (1.946 cm) were obtained from 1.0 mg/l each of BAP + IBA and the highest leaf width (1.166 cm) was obtained from 0.5 mg/l BAP +1.0 mg/l IBA combination. The highest root length was obtained from 0.5 mg/l each of BAP + IAA and the maximum number of regenerated plantlets (20) was obtained from 0.5 mg/l IAA + 1.0 mg/l IBA combination. However, the maximum fresh weight of single shoot (0.219 g) and the maximum number of roots per plantlet (6.300) was obtained from 1.0 mg/I each of IAA + IBA combination.

AbstractDeveloping a method for the control of cut flower opening and improvement of cut flower quality is important to meet consumer demand. In this study, we investigated the effects of methyl jasmonate (MeJA) on flower opening of three rose cultivars: ‘Red Star,’ ‘Princes Meg,’ and ‘Madrid’. Shoot bases of cut roses were immersed in water solutions containing 100- or 1000-μM MeJA in addition to 2% weight/volume (w/v) sucrose and 0.02% w/v 8-hydroxyquinoline monohydrate. Subsequently, the vase life, flower opening, petal wilting, petal weight, water uptake, and water evaporation were measured. Flower opening of all three cultivars was clearly delayed following the treatment with MeJA, resulting in prolonged vase life compared with control. In addition, flower wilting was suppressed in all cultivars. Moreover, 7 days following treatment, the petal fresh weight was maintained high in the ‘Red Star’ and ‘Princes Meg’ cultivars. However, there was no significant difference in the ‘Madrid’ cultivar versus control. In all three cultivars, there was a minimal difference in the total amount of water uptake and evaporation. Thus, it is suggested that the total amount of water uptake and evaporation have limited relevance to the changes in the relative fresh weight of cut roses and petal fresh weight observed following treatments. Despite the difference in the sensitivity of the rose cultivars to treatment with MeJA, we conclude that MeJA has high potential as a quality retention agent for cut roses.

Cyclamen species (swinebread spp.) are perennial herbaceous plants which belong to the Primulaceae family, widely used as medicinal or ornamental plants. Currently, gibberellic acid (GA3), an environmentally friendly bioregulator is widely used to enhance the productivity and phenotypic characteristics of multiple ornamental crops. A dual experiment was conducted to evaluate the influence of gibberellic acid (50, 100 or 150 mg/L), on germination earliness of seeds, along with growth and ornamental quality of selected Cyclamen species. Additionally, a greenhouse experiment with long and short sunlight photoperiod was conducted to evaluate its importance in the development of Cyclamen plants. Our results indicated that under short sunlight exposure, seeds germinated earlier than those kept in long sunlight photoperiod. Plants treated with foliar applications of GA3 exhibited higher plant height, leaf area, number of leaves, root length and tuber development. Significant differences were found in germination percentage (GP), mean germination time (MGT) and seedling vigor index (SVI), within different GA3 supplementation and greenhouse sunlight intensity (short and long days). In conclusion, our study suggests that seedling vigor and ornamental quality can be increased by GA3 application, an economic strategy for enhancing germination and growth of selected Cyclamen species.

A study was conducted to optimize plant spacing for cut Helianthus annuus cv. Pro Cut Orange and Zinnia elegans cv. Double Super Yoga. Seedlings were raised in 128-celled plastic plug trays containing coco coir, compost and silt (1:1:1; v/v/v) as substrate. At 2-4 true leaf stage, seedlings were transplanted outdoors in thoroughly tilled and leveled flat beds at plant and row spacing of 15.0 × 15.0, 15.0 × 22.5, 22.5 × 22.5, 22.5 × 30.0, or 30.0 × 30.0 cm with plant populations of 40, 26, 17, 13 or 10 plants per m2, respectively. Experiments were laid out in randomized complete block design with three replications individually for each species. Findings revealed that for Helianthus annuus, plants grown at 15.0 × 15.0 cm spacing produced tallest plants with greatest plant canopy diameter. While leaf area, stem diameter and vase life were highest for plants spaced at 30.0 × 30.0 cm. Plant spacing had no effect on number of leaves per plant, fresh weight of stem, flower quality and internodal distance. Similar results were recorded when this experiment was repeated on Helianthus annuus during next year for confirmation of results. In case of Zinnia elegans, plants spaced at 30.0 × 30.0 cm exhibited highest plant canopy diameter, number of leaves per plant and number of flowers per plant, while plants spaced at 15.0 × 15.0 cm had highest plant height and leaf area. Flower diameter, stem diameter, flower quality, internodal distance, fresh weight of a stem and vase life were similar irrespective of plant spacing. Based on the findings, it can be concluded that quality cut Helianthus annuus production was greatly improved when plants were spaced at 15.0 × 15.0 cm, while 30.0 × 30.0 cm spacing was optimal for cut Zinnia elegans production and may be used for commercial cultivation of Helianthus and Zinnia in Punjab.

AbstractTo understand the role that the leaves play in the translocation of soluble carbohydrates in cut rose flowers, we first evaluated the effect of leaf removal on flower quality and the sugar content in petals. Cut rose flowers with leaves had higher soluble sugar content in petals compared with cut flower without leaves. Next, we treated cut flowers with radioactive glucose to clarify translocation routes of exogenously applied sugar. There was no significant difference between the specific radioactivity of sucrose and glucose in leaves, but specific radioactivity of sucrose in petals was much higher than that of glucose. These results suggested that most of the exogenously applied glucose first moved to the leaves, where it was converted into sucrose and then the synthesised sucrose was translocated to the petals. Our results showed that the leaves of cut rose flowers play an important role in the metabolism and transportation of exogenously applied soluble carbohydrates toward the petals, thus contributing to sustaining the post-harvest quality.
