This study was aimed at investigating the effect of NAA and BAP on the development of basal slip slices in tissue culture of pineapple cv. Tangkit. The experiment was conducted at the Plant Biotechnology Laboratory Agricultural Faculty University of Jambi from July through to October 2016. Six level of NAA concentrations (0, 1, 2, 3 , 4 and 5 mgL-1) were tested in combination with six levels of BAP concentration (0, 1, 2, 3 , 4 and 5 mgL-1). A Completely Randomized Design with 5 replicates was employed in this trial. Data on the percentage of explants forming shoots, time required for shoot formation, number of shoots growing per explants, and callus proliferation were recorded. Results showed that without the involvement of plant growth regulators there had been no growth on cultured explants. However, shoot growth was found on explants cultured on medium supplemented with 1 – 3 mgL-1 NAA or 1 – 5 mgL-1 BAP. The application of NAA higher than 3 mgL-1 was found to suppress shoot growth even in combination with BAP. Shoot formation was found to be fast on medium supplemented with 1 mgL-1 NAA + 4 mgL-1 BAP, but took longer time on medium with or 1 mgL-1 NAA + 5 mgL-1 BAP as well as medium with 1 – 2 mgL-1 NAA only. The same phenomenon was also found on medium with 1 – 2 mgL-1 NAA only. This study also revealed that most of cultured explants regenerated only one shoot, but explants cultured on medium with 1 mgL-1 NAA along with 1 mgL-1 BAP produced 2.33 shoots on the average. The addition of 1 mgL-1 NAA without BAP and 1 mgL-1 BAP without NAA could increase average shoot growth by 1.78 and 1.44, respectively. Keywords: in vitro culture, micropropagation, naphthalene acetic acid, benzyl amino purine.

Agricultural land in Indonesia was largely dominated by untapped potential land, almost of that potential land is dry land. Maize (Zea mays L.) is one of the staple crops that are known could be cultivated on dry land. Rizosphere has been known to containmicroorganisms that can improve the plant growth. In the previously study, we have screenedin vitro of rhizobacteria (6 isolates of Pseudomonas sp CRB and 7 isolates of Bacillus sp CR) as growth promoter of maize and drought tolerant. A total of 6 rhizobacterial formula were further applied in vivo in greenhouse to promote the growth of maize. In planta test on maize showed that formula CRB 19 and F3 (CR 83 + CRB 10) were the best formula that could enhance plant growth parameters under drought stress conditions. After that abundance and activities of microbe were analyzed by enumeration of total fungus, bacteria and actinomycetes, dehidrogease test, soil respiration test dan C-microbe test and those tests showed that formula CRB 19 and F3 (CR 83 + CRB 10) were the best formula.These formula could be recommended as inoculants of maize planted in dry land agriculture.

Timpakul fish (Periophthalmodon schlosseri) is a kind of fish which able to live long in the land. One of the habitats of the fish is Barito river estuary. The development of land conversion which high enough at Barito river estuary into the area of fishponds and rice fields cause P. schlosseri must adapt to the environment disturbed. The research aimed to determine the adaptation of P. schlosseri in fishponds and rice fields habitats in Barito river estuary. The research is conducted by using the method of line transect, that is by walking in the area of rice fields and fishponds in Barito river estuary with the object of observation consisted of nest and activity of P. schlosseri. The results of observation showed that the density of P. schlosseri was relatively small at 0.54 individual/hectare in paddy fields areal and 0.84 individual/hectare the area of aquaculture. The relatively low density of fish was caused by nature solitary and carnivorous fish. The adaptation of P. schlosseri in the areas of fishponds and paddy fields could be successful because it was supported by adequate food source, that were crab, shrimp, frog and small fish and predators were relatively few.

Dates palms (Phoenix dactylifera L.) are species of plants which can be found commonly in the Middle East. The fruits are occasionally found and consumed during Ramadhan. There are several factors which can affect the growth of the plant, mycorrhiza is one of the example. Mycorrhiza is a form of mutualistic symbiosis between the root of plants and fungus. This symbiosis is proven to be favorable for plants, as it can help the absorption of the nutrient, help the defensive mechanism against pathogens, and support the plant to cope with the water deficiency. Furthermore, the plants may also have an alternate form of mutualistic symbiosis with the bacteria called endophytic bacteria which involves in the transaction of nutrient and mineral. This study requires the isolation of microorganisms that can be found within the root of date palms. The isolation can be done with the usage of Potato Dextrose Agar (PDA) as the media. There were several microorganisms which can be found within the isolated plant’s root. Through identification based on its morphology characteristics, the microorganism that was found probably are Staphylococcus; Bacillus subtillis; Glomeromycota sp., and Glomaceae sp. Keywords: Bacteria, dates, Glomaceae sp., Glomeromycota sp., mycorhizza
