Abstract

The need for orchids is increasing and the orchids are threatened with extinction due to forest exploitation and need to be supported by the provision of seeds using tissue culture technology. The research entitled regeneration of the pigeon orchid (Dendrobium crumenatum Swartz) aim of this study was to determine the effect of the interaction between the concentrations of growth regulators zeatin and sucrose on the growth of Dendrobium crumenatum Swartz callus in vitro. The experimental design used was a factorial randomized block design consisting of 2 factors. The first factor is the zeatin dose consisting of without treatment, 0.1, 1.0, and 10 ppm. The second factor is the sucrose dose consisting without treatment, 20, 40, and 60 g/l, there are 16 treatment combinations and 3 repetitions so that 48 experimental units were obtained. Each experimental unit consisted of 4 explants, so that a total of 192 explants were explants. The parameters observed were as follows: percentage of live explants, percentage of rooted explants, percentage of explants that formed callus, number of shoots, number of leaves, and chlorophyll content Follow-up test Honest Significant Difference (HSD) at 5% level. The interaction of zeatin and sucrose affects the survival percentage of explants and callus, the number of shoots and the number of leaves. The best treatment was 1.0 ppm zeatin and 40 g/l sucrose. The main effect of the best zeatin concentration is 1.0 ppm and the best dose concentration is sucrose 40 g/l.

Abstract

Research entitled The Effect of Colchicine Concentration on the Growth and Production of Black Soybean Plants of the Detam 2 Variety (Glycine soja (L) Merr). The aim of this research was to determine the concentration of LD47, as well as the effect of colchicine concentration on the growth and yield of black soybean plants of the Detam 2 variety (Glycine soja (L) Merr). The research was carried out at the Air Dingin experimental garden, Faculty of Agriculture, Universitas Islam Riau. The research period was carried out for six months from January to June 2023. The research carried out consisted of II stages. Phase I research was to determine the concentration of colchicine LD47 (Lethal Dose 47%). The treatment concentrations are: K0= 0 ppm, K1= 500 ppm, K2= 1000 ppm, K3= 500 ppm, K4= 2000 ppm, K5= 2500 ppm, K6= 3000 ppm, K7= 3500 ppm. Phase II research was carried out by inducing colchicine mutations using control and LD47. Phase II research was carried out to determine the effect on growth and production in control and treatment samples that had been mutated with LD47 concentrations. Phase I research showed the sensitivity of black soybean plants with a survival percentage of 47%. It can be seen that the LD50 concentration obtained was 3599 ppm and the concentration used for phase II was LD47 colchicine concentration of 3500 ppm. The effect of colchicine LD47 had a significant effect on the parameters of petiole length, number of branches, widest leaf area, stem diameter, flowering age, number of pods per plant and dry seed weight per plant. The effect of colchicine LD47 had no significant effect on the parameters of plant height, node or node length, percentage of pithy pods, fruit stalk length and weight of 100 dry seeds.

Abstract

The research entitled identification the phenotypic variance of qualitative and quantitative characters of oil palm (Elaeis guineensis Jacq.) origin of Angola. The objective of the study was to determine the specific characteristics of the oil palm population of dura and tenera Angolan germplasm on phenotypical characterization whether qualitatively and quantitatively as well. The research was conducted in seeds garden of the oil palm seeds company in Siak Hulu of Kampar District. The genetic material used in this study was oil palm germplasm as much as 1996 oil palms in 15.50 hectars. The Angola accession population consisted of 80 Dura accessions with 1,309 oil palms and 26 Tenera Accessions with 687 oil palms. The analytical method used is the Coefficient of Phenotypic Variation (KKF) and Principal Component Analysis (PCA). The results show that the main component of the quantitative variable can explain the variation of the Angolan oil palm population by 79.76% with parameters such as oil to bunch (%), oil to fruit (%), dry mesocarpto fruit (%), relative leaf area (m²), wet mesocarp to fruit, frond length, palm height, number of leaves, periole width (cm), and petiole cross-section (cm²). The proportion of low KKF with a high O/B average is found in AGO001, AGO086, AGO101, and AGO 106.
