Abstract

A wide range of imported ornamental sunflower seeds have been marketed in Indonesia. A field evaluation was conducted on seven sunflower cultivars to investigate their germination, growth and development in humid tropical environment in Bogor, West Java, Indonesia and to determine their potential uses. Most of the tested cultivars, except for ‘Sungold Double’ and ‘Velvet Queen’, demonstrated good germination and growth. ‘Eclipse’ was highly susceptible to stem rot, which resulted in only 30% of the plants survived. ‘Little Leo’, ‘Teddy Bear’ and ‘Sungold Double’ were naturally compact, dwarf, and produced attractive blooms so they might be suitable as pot plants. ‘Hallo’, ‘Velvet Queen’, ‘Sunburst’, and ‘Eclipse’s plant height were more than 100 cm, had long stem and large blooms. These cultivars might be suitable as landscape plants.Keywords: morphological characteristics, West Java, pot plants

Abstract

The objective of this study is to study the effect of gamma ray irradiation (15, 30, 45, and 60 gray (Gy) to determine Lethal Dose 50 (LD50) values, and to obtain new Coleus variances in a relatively short time. The study was conducted in a greenhouse at Cikabayan experimental field, Bogor Agricultural University, Darmaga, Bogor in May to July 2013. Gamma irradiation treatment significantly affected height, number of leaves, and number of nodes. Increasing the dose level of gamma irradiation tend to inhibit plant growth. LD50 for yellow/green, green/brown, variegated green/brown of Coleus blumei, and Coleus amboinicus Lour were 48.66, 65.2, 52.81, and 37.62 Gy respectively. C. amboinicus  irradiated at a dose level of 45 Gy had different leaf shapes compared to control. Keywords:  Coleus, gamma ray irradiation, LD50 values, ornamental plant, torbangun

Abstract

Torbangun (Coleus amboinicus Lour) is a tropical plant from the Lamiaceae family. Torbangun leaves have a distinct aroma. Torbangun leaves have been traditionally used as a medicinal plant in North Sumatra, Indonesia. Bataknese lactating women in North Sumatra consumed torbangun leaves after giving birth with beliefs that it could increase their breast milk production (lactagogue), and that the leaves can function as anti-fungal and/or anti-bacterial, analgesic, to reduce blood cholesterol, and clean the human uterus. However, scientific evidence on this traditional herb is limited. This research was conducted to: (1) determine the leaf N, P, K, Ca and Fe in different position along the plant and the leaf age as to diagnose the secondary metabolites content of torbangun leaves, and (2) determine the relationship between N, P, K, Ca and Fe leaf concentrations with their metabolite production. The results of the study showed that: (1) the best leaf position and age to determine of the need of N, P, K, Ca and Fe nutrients are on the 3rd leaf position of 5 months-old plant (2) There was a positive correlation between leaf K concentrations with shoot dry weight, Ca with PAL activity, and Fe with total saponins on the 3rd leaf position of 5 months-old plant.Keywords: Coleus amboinicus Lour, torbangun, nutrient, correlation test, secondary metabolites.

Abstract

Characterization is part of crop the breeding process aims to protect biodiversity and preserve local germplasm. Indonesia has two known species of Portulaca, Portulaca oleracea and P. grandiflora. Thirteen Portulaca accessions have been collected from Bogor area, comprising five accessions of Portulaca oleracea and eight accessions of Portulaca grandiflora. This study was aimed at the characterization of the 13 accessions and was undertaken at Indoflower BLST, Bogor, between October 2015 to February 2016. The results showed a significant difference in the color of flowers between the two species of Portulaca. The most significant difference is the overall appearance of P. oleracea species. Character color and shape of the flowers between the P. grandiflora white (GW) and P. oleracea are similar.  Significant differences between the species exist in relation to the root systems, but the root systems of accessions within each species are generally similar.  The branching characteristics between the two species and among accessions are generally similar, with branches emerging through the base of leaves or nodes.   However, there are differences in the leaf characteristics between the two species. This study has provided information on flower characteristics of P. grandiflora and P. oleraceae which will be valuable for future breeding efforts in Portulaca.

Abstract

Plantlets of the ornamental plant Celosia cristata were irradiated with gamma rays to increase their genetic diversity. This study was aimed to establish  the lethal levels of gamma radiation  (LD20, LD30 and LD50) for  C. cristata plantlets.   The irradiation doses used were 0, 25, 50 and 75 Gy. The growth of irradiated plantlets was evaluated to the third generation. Irradiated C. cristata MV1 plantlets showed a decrease in growth, with plantlets irradiated at 75 Gy showing only 30% survival.   Abnormal growth characteristics observed  in the  third generation plantlets included  the shortening of internodes, and curling of leaves.  LD50, LD30 and LD20 of C. cristata were 68.73 Gy, 46.68 Gy and 35.65 Gy, respectively.

Abstract

Etlingera elatior is tropical ornamental plant commonly called “torch ginger” from Zingiberaceae family. Conventional breeding of E. elatior is limited by cross incompatibility, poor fruit set and low seed production.  In this study irradiation of E. elatior with Gamma ray performed to induce mutation. This study was aimed to increase morphological diversity and to obtain unique morphological characters to increase the aesthetic value of E. elatior as ornamental plants and cut flower. Two genotypes of E. elatior, red and white flowers, were tested. The LD20, LD35, and LD50 were determined following intermittent (split dose) Gamma irradiation with a two-hour gap between each gamma ray shot. Red genotype E. elatior explants were irradiated with dose of 3 + 3 Gy (LD20); 4 + 4 Gy (LD35) and 5 + 5 Gy (LD50); white genotype were irradiated with a dose of 2 + 2 Gy (LD20); 2.8 + 2.8 Gy (LD35) and 3.7 + 3.7 Gy (LD50). Non-irradiated explants were set as control.  The results of this study indicated that the increase in dose of gamma ray irradiation changed shoot length and number of leaves in the red genotype per explant as compared to control. Morphological changes occurred in leaf shape at 5 + 5 Gy and 3.7 + 3.7 Gy and formation of variegated leaves at 2.8 + 2.8 Gy and 5 + 5 Gy. Keywords: mutation breeding, ornamental plant, split irradiation dose, torch ginger, Zingiberaceae

Abstract

Marigold (Tagetes erecta L.) is an ornamental plant widely used as a potted or cut flower due to its vibrant colors and diverse flower shapes. High genetic diversity is essential for successful breeding programs aimed at developing superior varieties. Genetic information can be obtained by estimating variance components and heritability values, key parameters in plant breeding. A high heritability value suggests that genetic factors influence a plant's characteristics more than environmental factors. This study assessed the genetic diversity and performance of vegetative propagation from 2nd generation mutant plants (M2V1). The research was conducted at the Pasir Sarongge experimental field in Cianjur Regency from July to October 2023, using a randomized complete block design with 17 genotypes and three replicates. The genotypes included 14 from vegetative propagation of M2V1 mutant plants and three comparison varieties: “Maharani”, “BAIP 2”, and “BAIP 3”. Data analysis was performed using PKBT-STAT 3.1 software, followed by the honest significant difference (HSD) test at the 5% level. The results revealed significant differences among genotypes in plant height, stem diameter, canopy width, leaf width, flower weight, flower diameter, number of flowers per plant, total flower weight per plant, and flower stalk length. Floret types observed were either all ligulate or all tubuligulate, with flower colors ranging from orange to yellow to white. Traits such as canopy width, flower weight, flower diameter, and stalk length, which exhibited broad genetic diversity and high heritability, can be used for selection in future marigold breeding programs.
