The study aimed to obtain morphophysiology information on fruit-drop events in chili plants on application of plant growth regulator (PGR) auxin (IAA and IBA) and gibberellins. The study was arranged based on a split-plot design in a randomized block design with 3 replications. The main plot is 3 types of PGR namely IAA, IBA, and GA3. The subplots are 5 levels of concentrations (ppm): 0, 25, 75, 50, and 100. The data were analyzed using STAR software and Smallest Significant Difference (LSD) 5%. The results showed that the application of PGR and concentration did not significantly affect the number of attached and abscised flowers. However, the application of PGR resulted in a higher number of attached flowers than the abscised flowers. Giving IAA 25 ppm produced the highest number of fruits compared to other IAA concentrations. Increasing the concentration of GA3 tends to increase the number of attached fruits and the highest at 100 ppm GA3. The interaction between PGR and concentration significantly affected the weight per fruit. The treatment of GA3 100 ppm produces the highest weight per fruit. Increasing the concentration of auxin tends to reduce the weight per fruit. The IBA 100 ppm decreases the length of chili.

Tungro virus is one of the rice diseases which become one of limiting factors for rice production in Indonesia. The effective control can be done by using and rotation of resistant varieties. In order to develop tungro resistant varieties, hybridization has been conducted between susceptible (Ketonggo) and resistant variety (Utri Merah and ARC12596) i.e., Ketonggo x Utri Merah and Ketonggo x ARC12596. The main objective of the study was to characterize the physiological response of recovery genotypes group when compared to resistant genotypes. The genetic materials were F2 progenies of Ketonggo x Utri Merah and Ketonggo x ARC12596, each 230 genotypes. The experiment was conducted at BB Padi and Experimental Station of Faculty of Agriculture, Universitas Padjadjaran. Virus transmission was done using forced-tube inoculation method and symptoms scoring based on a standard evaluation system for rice. Traits observed were chlorophyll content, number of stomatal conductance, and quantum photosynthetic efficiency. The comparison of those traits between genotypes with recovery ability with those of resistant genotypes, susceptible genotypes, resistant variety check, and susceptible variety check was evaluated. It is found that recovered genotypes from both crossings did not show significant differences with those of resistant genotypes or resistant check variety on the above traits observed. Genotypes group with recovery ability can be used to suppress the spread of tungro disease.

Seed decline is a certain occurrence. Local rice variety planting by farmers generally uses seeds from the previous crop and has been stored for a long time before being replanted. This study aimed to determine the optimal hydropriming invigoration material in improving the physiological quality of some Jambi local rice varieties. The treatment was applied to factorial complete randomized design with 3 replications. 1st factor was rice varieties: Padi Karya, Kuning Betung, Kuning Kerinci, and Gadis Jambi. 2nd factor was invigoration consisting of control (aqua dest), red onion solution and a solution of young coconut water. A total of 30 seeds for each experimental unit were soaked for 24 hours. Seeds were planted on moist filter paper media according to a test method on paper. Results showed that there were no significant interactions between varieties and invigoration on the germination of local rice seeds tested. The invigoration treatment using coconut water significantly affected root length, plumula length, normal sprout length, and local rice vigor index. Kuning Betung variety provides the best response to invigoration. Invigoration treatment is an effort to improve seed performance to reduce the risk of failure on field plantation, expected to have the implications for increasing rice production.

Watermelon [Citrullus lanatus (Thunberg) Matsum & Nakai] is a plant that is widely cultivated and contains important nutritional compounds such as citrulline, arginine, and glutathione. In the last few years, the consumption of vegetables and fruits in Indonesia has tended to increase but cannot be fulfilled by domestic production. Yields are influenced by the character of yield components. This research aims to study the relationship between yield component traits and yield of watermelon. The study was arranged in augmented design and planting material are 75 watermelons genotypes and 3 checks varieties. The results showed that there are some characters of yield components that correlated with yields. The characters of yield components that have positive genetic correlation and positive phenotype correlation with fruit weight are stem length, number of branches, fruit stalk length, fruit length, fruit diameter, thickness of pericarp, number of seeds per plant, and weight of seeds per plant. The yield components characters that have a negative genetic correlation with fruit weight are day to flowering. The characters of yield components that have positive genetic and phenotype correlation with seed weight per plant are fruit weight, stem length, fruit length, fruit diameter, number of seeds per plant, seed length, and seed width. The Characters of yield components that have a negative genetic correlation with seed weight are day to flowering and the first female flower emerges. The characters of yield components that correlate with the yield are used as selection markers for indirect selection.

Durian nurseries can be done using generative and vegetative material sources. Both sources of propagation have their respective weaknesses and strengths. Quality seeds are obtained through a combination of two sources of propagation material that have each of the advantages that can complement each other. The process of merging can be through mini grafting. The mini grafting method in durian nurseries can use side grafting and shoot grafting methods. This study wants to examine the relationship of carbohydrate, protein, and fat content to the successful growth of mini grafting results on durian plants. The research was carried out by analyzing the carbohydrate, protein and fat content in the upper stem which will be used for grafting, as well as observing and measuring the growth process of mini grafting plants. It was concluded that the carbohydrate content of the upper stems gave the highest positive contribution to the increase in the number of shoots followed by the number of leaves, percentage of living grafts, leaf area, leaf area ratio, root canopy ratio, shoot length, and stem diameter. The protein and fat content cannot contribute to the growth even has a tendency to inhibit growth of grafted seeds.

Oyster mushrooms have the conditions of growing at low temperatures and high relative humidity, so when you want to cultivate it is needed an appropriate environment for the growth and development of oyster mushroom. Banjarbaru City tends to have high temperatures with a relative humidity that tends to below. This is quite different from the requirements for growing oyster mushrooms which require low temperatures with relatively high humidity. One of the easiest and cheapest methods to maintain temperature and relative humidity to remain ideal and appropriate is to water the surrounding oyster mushrooms growing media, so knowledge of the most appropriate and ideal watering frequency for growth and development of oyster mushrooms is needed. The environmental design used was a Completely Randomized Design (CRD), a single factor with 4 treatments, 5 replications, so that 20 experimental units were obtained. The treatments are p1 = once watering per day, p2 = twice watering per day, p3 = three times watering per day, p4 = four times watering per day. The result showed that the watering frequency showed significant difference to the growth time of oyster mushroom shoots and the wet weight of oyster mushrooms. The best treatment in accelerating the growth time of oyster mushroom shoots and increasing the wet weight of oyster mushrooms is four times watering frequency per day.
