Abstract

The increasing number of Phalaenopsis sp. enthusiasts needs to be balanced with the availability of good-quality cultivars, one of which can be achieved by improving flower morphological characteristics through colchicine induction. Colchicine-induced plants often exhibit superior traits such as larger, thicker, and more durable flowers. This study aimed to investigate the effect of a 1500 ppm colchicine concentration on the floral morphological characteristics of the Phalaenopsis sp., with a particular focus on flower size, petal thickness, and sepal morphology. This research provides genetic diversity information on Phalaenopsis sp., which can serve as a basis for future breeding programs and as a reference material for orchid growers and researchers. The materials used were flower buds of three Phalaenopsis varieties: Phalaenopsis Fuller’s Sunset, Phalaenopsis Golden Tree, and Phalaenopsis OX X-Ray. Each treatment was replicated three times. Morphological data were analyzed qualitatively through scoring and converted into binary data according to the Guide Book of Orchid Plant Characterization by the Ornamental Plant Research Center (2007). The results showed that 1500 ppm colchicine affects Phalaenopsis Fullers Sunset in the form of rhombus-shaped petals, and on Phalaenopsis Golden Tree in the form of pointed lateral sepal tips, concave transverse and longitudinal cross-sections of petals, and on Phalaenopsis OX X-Ray in the form of split dorsal sepal edges, and open petal arrangement. Overall, colchicine treatment also induced apparent enlargement of flowers in all three Phalaenopsis hybrids. Keywords: chromosome; flower morphology; mutagenesis; ornamental plant; polyploidy

Abstract

The Kepok Unti Sayang variety is a superior type of banana that is resistant to fusarium wilt. The high demand for Kepok Unti Sayang needs to be balanced with good seed production. One of the methods used for multiplying superior seeds of Kepok Unti Sayang is through tissue culture. This research aims to obtain the optimal concentration of Naphtaleine Acetic Acid (NAA) in the subculture media for the growth of root numbers in the Kepok Unti Sayang Banana. The second objective is to determine the optimal concentration of Benzyl Amino Purine (BAP) in the subculture medium for shoot number growth in Kepok Unti Sayang bananas. Another goal is to identify the best treatment combination that can produce the highest number of shoots in Kepok Unti Sayang bananas. The research was conducted at the Laboratory of Plant Physiology and Biotechnology at Sebelas Maret University from February to July 2025. The study was conducted with 4 levels of NAA treatment: 0; 0.5; 1; and 1.5 ppm. The BAP treatment was administered at 4 levels: 0; 1; 2; and 3 ppm. The variables observed in this study were the time of shoot emergence, number of shoots, time of root emergence, root length, and final height of the planlet. Data from each variable were then analyzed using analysis of variance (ANOVA) with an F-test at a significance level of 95%. Significantly different data were then followed by Duncan's Multiple Range Test (DMRT) at a significance level of 95%. The significant combination of NAA and BAP on the observed variables was then reanalyzed using regression tests. The results showed that the application of various concentrations of NAA does not affect the growth of the number of roots of Kepok bananas var. Unti Sayang. The application of 2 ppm BAP is optimal for the growth of the number of shoots of Kepok bananas var. Unti Sayang. The interaction between 1 ppm NAA and BAP at 1-2 ppm produces the most optimal average shoot emergence time.

Abstract

Barangan banana is a banana variety that has high economic value, but its production is still carried out conventionally, resulting in limited barangan bananas on the market. The use of tissue culture methods can quickly produce high-quality, disease-free plants regardless of seasonal conditions. The aim of this research is to determine the effect of providing the best ZPT IAA and BA for the growth of the Barangan banana planet. The research was conducted in August-October 2023 at the Biotechnology and Plant Physiology Laboratory, Sebelas Maret University. This research used a two-factor Completely Randomized Design (CRD) with 6 replications. The first factor was the use of ZPT Indole Acetic Acid (concentrations 0, 0.5, 1, and 1.5 ppm and the second factor was the use of ZPT Benzyl Adenine (0, 0.5, 1, 1.5 ppm). The variables observed were root emergence time, number of roots, root length, time of leaf emergence, number of leaves, time of shoot emergence, number of shoots, and height of shoots. The observed data were analyzed using Analysis of Variance (ANOVA) with a 5% level test and if there was a significant difference, it was continued with Duncan's Multiple Range Test (DMRT) at the level 5%. The results showed that giving 0.5 ppm IAA increased root length; 0.5 ppm IAA was given optimally for root formation; and 1 ppm IAA increased the shoot height of the Barangan banana plnalet. Giving BA 0.5 ppm root number; BA 1, 5 ppm produces the highest number of leaves; BA 1 ppm increases shoot height of barangan banana plantlets.
