Carnation (Dianthus caryophyllus L.) is one of the most commercially important cut flowers of the world. It can be used for cut flowers, bedding, edging, boarders, pots and rock garden. Four Spanish carnation varieties were tested with three levels of boron under ultra-violet stabilized polytunnels from August 2017 to April 2018 at Godawari, Nepal. The objective of the research was to evaluate vegetative, floral, and vase life parameters in relations to growth, yield and quality of carnation. The research was conducted in a randomized complete block design with 3 replications. The variety Baltico had the maximum leaf length (19.3 cm), numbers of lateral branches (10.5), internodal length (5.1 cm), flower diameter (8.6 cm), and vase life (24.0 days). The numbers of nodes (5) and flower weight (25.4 g) were highest in the variety Vinco with the lowest cracked area on the stem (0.2 cm2/ crack). The numbers of stem cracks per plant significantly (p ≤0.01) reduced with an increasing level of boron though non-significant relation was observed on 60 ppm and 120 ppm. Variety Baltico was found as a better variety compared to the Vinco, Cervantes and Master varieties according to the vegetative, floral, yield and vase life parameters. Among the levels of boron tested, 60 ppm was found as the optimum dose. Thus, variety Baltico and 60 ppm boron is suggested to be used at the climatic condition of Lalitpur.

Abstract Gladiolus is one of the most important and popular cut-flower bulbous in Iran. The aim of this research was to produce new, high-quality hybrids through hybridization. We generated two promising hybrids (OPRC16 and OPRC57) combination from the varieties “Amsterdam” and “White Prosperity”. The Research was conducted in Ornamental Plants Research Center in Mahallat from 2014 to 2018. Values of Hm for traits were defined as the difference between the mid-F1 value and the mid-parent value, Mean Mid-parent Heterosis (MPH) or (Hmp) and High Parent Heterosis (HPH) or (Hsp). The results showed that the morphological analysis revealed the heredity and variation in the promising hybrids. The results for the hybrid OPRC16 showed that the Hm and Hmp values were negative for peduncle length but positive for other traits. The Hsp value was observed to be negative for the traits of peduncle length, leaf width, stem diameter, and cormels diameter, but it was positive for other traits. According to the results for the hybrid OPRC57, the Hm and Hmp values were negative for plant height, floret number, peduncle length, floret diameter, stem diameter, spike length, cormles weight, and cormlet diameter and negative for other traits. Peduncle length was positive in other traits. The Hmp value was negative for peduncle length, but positive for other traits. The Hsp value was recorded to be positive for leaf length, bud diameter, vase life, cormlet number, and cormles yield but negative for other traits. All in all, OPRC57 showed a negative heterosis in most traits. Based on the results, when ‘Amsterdam’ is used as the maternal plant in crosses, it has more positive heterosis effects than when it is used as the paternal parent. These results indicate that major of traits in the phenotypic and genetic diversity coefficient was very low, indicating that they had less environmental effects, since the genotypes were cultivated under similar and controlled conditions.

A field experiment was conducted at the research field of Sher-e- Bangla Agricultural University, Dhaka during the period from December 1, 2016 to January 11, 2017 to investigate the effect of gibberellic acid (GA3) on vegetative growth, morphological attributes and foliage (leaf) yield of coriander (Coriandrum sativum L.). The experimental treatments consisted of eight different doses of GA3 viz., 0 (distilled water spray), 5, 10, 15, 20, 25, 30 and 35 ppm. The variety Rosina (Pahuja Co., India) was used as planting material and different doses of GA3 were applied on the plants at 25 and 30 days after sowing. The experiment was laid out in Randomized Complete Block Design with three replications. GA3 had significant effect on vegetative growth, morphology, foliage yield and yield contributing characters of coriander. Plant height, number of leaves plant-1, leaf length, plant spread and single plant weight were found maximum from the application of GA3 at 20 ppm, which was closely followed by 25 ppm GA3. Application of GA3 at 20 ppm produced the highest weight of foliage m-2. A strong positive correlation of foliage yield was observed with plant height, number of leaves plant-1, leaf length, plant spread, single plant weight and weight of foliage m-2. Application of GA3 at 20 ppm gave maximum foliage yield (9.34 t ha-1) which was followed by GA3 at 15 ppm (8.46 t ha-1) and 25 ppm (8.06 t ha-1), and the minimum foliage yield was recorded from control (distilled water spray) (4.90 t ha-1). Application of GA3 at 20 ppm increased foliage yield over control by 47.54 %. A quadratic relationship between applied GA3 concentration and foliage yield was found; the regression equation was y = 4.87 + 0.375x – 0.009x2 from which it came up to be optimum dose of GA3 as 20.83 ppm.Res.

Cut flowers of Dianthus caryophyllus L. cv. GIOKO were treated with different concentrations of sucrose and in combination with 1­methylcyclopropene (1-MCP) to compare the effect of these treatments with floral preservative (`Spring') on the longevity of flowers. Distilled water was used for preparing all solutions. The control flowers were held in distilled water. Clorox at 2 mL- I was added to all treatments containing sucrose and it was also applied as a separate treatment. The vase life of cut carnations was significantly prolonged due to the use of chemical treatments, as compared to the untreated control. The longest vase life (18.33 days) was obtained by using 1-MCP 0.5 g m-3 for 6 h treatment. All concentrations of sucrose had a positive effect on flower diameter. The best treatment in this respect was 1 -MCP with 30 gL-I sucrose. 1-MCP treatment significantly increased the chlorophyll content, as compared to the control or the "Spring" treatment. The highest values in this respect were obtained by 1 -MCP treatment alone or with the lowest level of sucrose. The effect of these treatments on the pH of solutions is discussed.

Abstract Vegetative growth of ‘Alice du Pont’ mandevilla can be controlled by selection of an appropriate foliar application rate of Sumagic (uniconazole) and application interval. A single application of 5 to 20 ppm ai Sumagic (uniconazole) controlled vegetative growth for only 3 to 4 weeks; after this time, growth rates were similar to control plants. Multiple applications of 5 to 20 ppm ai Sumagic (uniconazole) effectively restricted vegetative growth; as the concentration of Sumagic (uniconazole) increased, the interval between applications increased from about 4 (5 ppm) to 6 (20 ppm) weeks. A single application of higher rates (30 to 120 ppm) of Sumagic (uniconazole) was phytotoxic. Generally, time to flowering increased and flower diameter decreased when application rate increased.

An experiment was carried out using eight double cross F1s (DCF1s) as lines and two testers to obtain sixteen Line ×Tester hybrids for the evaluation of major growth and flowering traits thereby to understand the breeding potentiality of the parental lines. The performance of growth and flowering traits of all twenty-six genotypes were evaluated in a randomized complete block design (RCBD) with three replications. The analysis of variance (ANOVA) showed all the genotypes were significantly different for all agro-morphological traits under study. The estimated general combining ability (GCA) effects showed that parent 5(P5), were superior for plant height, stem diameter, number of leaves, leaf length, days to flowering and attitude of floral axis followed by parent 2(P2) for leaf length, leaf width, days to flowering and attitude of floral axis and parent7 (P7) for number of flower, flower diameter, bud length and attitude for floral axis. Likewise; tester 1 found to be best combiner with significant GCA effect for almost all growth and flowering traits (except number of leaves). The plant height, leaf width, number of flower and attitude of floral axis showed prevailing additive gene action while stem diameter, number of leaves, leaf length, days to flowering, flower diameter and bud length indicated predominance of dominance gene action. We can conclude that parent P5, parent P2 and parent P7 can be used as good mother lines and the tester 1, as good donor for the seed production. SAARC J. Agri., 17(1): 175-187 (2019)

Foxtail millet (Setaria italica (L) P Beauv) falls on the category of underutilized crops in Nepal and mainly cultivated in Karnali region of the country. It is hardy crop and considered as one of the potential crops for future food security with respect to climate change. Five accessions of Nepalese foxtail millet were purposefully selected for evaluation of the agro-morphological characteristics. Foxtail landraces from Dolpa, Mugu, Bajura, Bajhang and Lamjung districts of Nepal were evaluated at Khumaltar, Lalitpur, Nepal during 2010. The plot size was 1m2 and there were five samples. Days to heading and days to maturity varied from 33-56 and 59 to 87 days after germination respectively. Similarly, flag leaf length/breadth ratio, flag leaf sheath length, ligule length, peduncle length, peduncle exertion and plant height varied from 3.84-10.90, 5.47-9.84 cm, 0.1-0.2 mm, 10-22.57 cm, 2.7-13.58 cm and 41.67-120 cm, respectively. Fruit and apiculus color varied from straw to black. All accessions were actively growing with very slight lodging. Similarly, the thousand grain weight varies from 1.064 g to 2.172 g. This variation is useful in foxtail millet breeding program. Similarly, the significant correlation between thousand kernel weight and total basal tiller (r=-0.975) showed that foxtail millet lines with low tillering ability is better for yield enhancement.

Introduction: The procedure to synthesize silver nanoparticles (SNPs) from Prunus cerasoides leaf extract and their effect on vase life and flower quality of cut carnation were investigated. Methods: SNPs were bio-synthesized from Prunus cerasoides leaf extract and characterized by using UV-Vis technique, TEM, and SEM images. The postharvest responses of carnation cut flowers to the biosynthesis SNPs were evaluated through vase life, relative fresh weight, vase solution uptake, flower diameter of cut carnation. Results: SNPs were synthesized under optimum conditions, including using the extract of leaf heating at 60 oC in 30 min, 4 mM of silver nitrate, pH of 11, and 180 min of reaction time. SNPs exhibited antimicrobial activity and then alleviated the bacterial development in the preservative solution. All treatments with SNPs had improved the vase life and quality of cut carnation compared to the control. A vase solution containing 2% sucrose enhanced the carnation cut flowers. Conclusions: The preservative solution containing 25 ppm SNPs and 2% sucrose showed the best effect. SNPs could be used as a promising antibacterial agent applied in the preservative solution for cut carnation flowers.

We investigated the effect of paclobutrazol as preplant bulb soaks on plant heightof Iris x hollandica cv. ‘Frans Hals’ and ‘Blue Magic’cultivars which were grownin pots. Bulbs of iris were soaked into gibberellin inhibitor paclobutrazol solutionat 0, 15, 30 ppm before planting. Effect of paclobutrazol on the flowering time,flower diameter and length, leaf length, plant height, flower life, and chlorophyllcontent of leaves were determined. The shortest plant height was obtained from the‘Blue Magic’ cultivar treated with 30 ppm paclobutrazol which gave plants with11.3 cm, 68% shorter than untreated control. ‘Frans Hals’ cultivar treated with 30ppm paclobutrazol was 20.9 cm and 50% shorter than control. In ‘Blue Magic’ and‘Frans Hals’cultivars the lower dose of 15 ppm paclobutrazol were also effectiveon height control with 11.8 and 21.5 cm plant height, respectively. This gibberellininhibitor also shortened the leaf length of iris cultivars. Paclobutrazol treatmentsresulted in higher chlorophyll content per unit area in the leaves. The highestchlorophyll content (57.00 CCI) was obtained from the ‘Blue Magic’ iris treatedwith 30 ppm paclobutrazol, while the control plants had 32.70 CCI chlorophyll intheir leaves. Chlorophyll content of ‘Frans Hals’ treated with 30 ppm paclobutrazolwere 52.87 CCI, while control plants of this cultivar were 28.80 CCI. Plantsapplied with paclobutrazol resulted with smaller flower diameter compared to thecontrol plants of both cultivars. The smallest flower diameter was obtained from 30ppm paclobutrazol treatment with 38.83 mm in ‘Blue Magic’ iris while the controlof this cultivar was 99.63 mm. The flower diameter of ‘Frans Hals’ cultivar treatedwith 30 ppm paclobutrazol was 109.1 mm, while the control one was 112 mm.
