Orchids are one of the most important ornamental plants in the world. The existence of natural orchids in their habitat is approaching extinction rate, so it is necessary to increase the diversity of orchids by crossing them. The Vanda orchid is one of the famous orchids in Indonesia because of its uniqueness. Vanda orchids have a very abundant diversity, so they can increase the potential of orchid plants. This study used a hybrid orchid plant Vanda celebica x Vanda dearei irradiated by Gamma-rays with a dose of 0 Gray, 10 Gray, 20 Gray, 30 Gray, 40 Gray, and 50 Gray. The data obtained from the observations will be analyzed using descriptive methods by observing each plant in various doses of Gamma-ray radiation compared with control treatment and presented in the form of boxplot images. The irradiation dose of hybrid Vanda orchids (Vanda celebica x Vanda dearei) increased the diversity in the parameters of plant height and leaf width. The application of a dose of Gamma-ray irradiation did not cause a significant interaction with the variable number of leaves. The diversity value decreased in the parameters of leaf length and number of roots. Application doses of Gamma-ray irradiation of 10, 20, and 30 Gray can change the leaves into grooves compared to control plants. Mutant plants had lower chlorophyll content than control plants (0 Gray).

Avocado is a fruit crop that is commercial and potential to be widely cultivated. Market demand for avocado was increased so production of avocado seed must increase too by grafting. The problem of grafting is often found in the connection between scion and rootstock that showed like elephant foot phenomenon, so it was necessary to study the linkage process between scion and rootstock. This research leads up to an increased percentage of finished graft seedlings that were ready for planting in the field. This method used a factorial experiment consisting of 2 factors. The first factor was the stages of entres (flushing, endodormancy, and ecodormancy), and the second factor was the grafting method (cleft graft, wedge graft, and splice graft). The research design used Complete Randomized Design with 4 replications and ANOVA with BNJ 5% test. The results showed all observations parameters interacted. Stage ecodormancy in splice graft resulted of vascular tissue (xylem and phloem) between scion and rootstock recovered better than other combination treatments by producing the best-grafted avocado seedlings growth with an increased percentage of grafted seedling by 42.50%, an interval of flushing by 4.91 days, and increased frequency of flushing by 1.83 times compared to stage flushing in cleft graft.

Biochar is a carbon-rich solid material made by pyrolyzing agricultural residual biomass, and it decomposes much more slowly than the biomass from which it is made. Biochar has been shown to have agronomic benefits. Biochar can provide agronomic benefits for a longer period due to its persistence in the soil. The purpose of this research is to gather evidence demonstrating that biochar has a longer effect on increasing aerobic rice productivity. A pot experiment was carried out in UNINUS. The treatments were as follows: control, 20 Mg rice husk biochar (RHB), 40 Mg RHB, 50 Mg RHB, 60 Mg RHB, 10 Mg RHB + 10 Mg composted poultry litter (CPL).ha-1, 20 Mg RHB + 20 Mg CPL.ha-1, 30 Mg RHB + 30 Mg CPL.ha-1, and 30 Mg RHB + 30 Mg CPL.ha-1. Treatments were started in September 2018, and the effects were measured from February to June 2019. The findings revealed that rice husk biochar and its combination with CPL increased aerobic rice growth (plant height, number of tillers, and yield). The most effective combination rate is the application of biochar and composted poultry litter, 20 Mg RHB + 20 Mg CPL.ha-1, because it significantly extended the residual effect. The combined application increased rice productivity when compared to a single application of biochar and composted poultry. The residual effect of biochar and composted poultry litter on rice productivity was superior to fresh application.

Breeding programs need genotypic variation to make a selection and create a promising variety. Hybridization in plants produces genetic variations in the offspring to select Robusta coffee as superior planting material. The maternal-effect and combining ability help determine the next breeding strategy. This study aimed to determine the maternal effect and the combining ability on the morphological characters of branches and leaves of Robusta coffee diallel crosses. The study involved six groups of F1 offspring and their reciprocals from three parents, namely clones BP961, Q121, and BP409, which were planted singly side in the Kaliwining Experimental Garden, Jember, East Java. The estimation of female parental effect was analyzed using a t-test, and combining ability was analyzed using diallel analysis method III. The analysis results showed that the female parental effect occurred on the character of the internode length in all cross combinations and did not occur on stipule length, petiole length, leaf length, and leaf width. The parent of the cross that can be the best combiner was parent BP961 for the petiole length and leaf length, parent Q121 for stipule length and internode length, and parent BP409 for leaf width character.

Toboali pineapple variety is a smooth cayenne variety because it contains high antioxidants in the form of vitamins A and C. In addition, it is a source of citric and malic acids, substances that can be used to enhance the taste of the fruit. Pineapple is a plant that is propagated with vegetative organs such as suckers, slips, and crowns. However, conventional propagation has a low propagation rate. Tissue culture is an in vitro technique used in the rapid propagation of plants and in large quantities to meet the needs of cultivation and research. The selection of regeneration media is very influential on the development of plants in tissue culture. This study aimed to obtain the optimal media combination with BAP and NAA in the regeneration of Smooth Cayenne pineapple (Toboali) in vitro for mass propagation of seedlings and genetic engineering research. This study used 6 levels of BAP, namely 0, 1, 2, 3, 4, 5 mg.L-1 and 4 levels of NAA, namely 0, 1, 2, 3 mg.L-1. The treatment used was a combination of BAP and NAA as many as 24 treatments with 3 replications. The best pineapple regeneration medium for mass plant propagation in this study was BAP 3 mg.L-1 without NAA media which produced the highest shoots of 17.33 shoots per explant at 12 week after planting. The best pineapple regeneration medium for genetic engineering research was a combination BAP 3 mg.L-1 and NAA 2 mg.L-1 media which produced 18.33 shoots per explant from embryogenic callus.
