Efforts to cultivate sungkai plants are hampered due to the limitations of good seedlings. Sungkai plants reproduce by seeds and stems (cuttings). This research will try to investigate the effect of using Growth Regulatory Substances (ZPT)against stem cuttings of sungkai plants. The study was designed in the Draft Randomized Complete (CRD) with 2 factors, each with 5 treatments. The factors tested were (1) synthetic auxin (Rootone F) with 5 concentrations, i.e. 20 grams / l (R1), 40 grams / l (R2), 60 grams / l (R3), 80 grams / l (R4) and 100 gram / l (R5); (2) natural auxin (onion extract with 5 concentrations, i.e. 20% (B1), 40% (B2), 60% (B3), 80% (B4) and 100% (B5). Besides that control plots were also carried out, which were not treated at all. Each treatment was repeated 3 times, so in a manner in total there were 33 experimental units (including 3 treatment experimental units control). The results showed that giving Rootone F solution affected the growth of sungkai stem cuttings (Albertisia papuana Becc.) on the observed variabels, namely shoot height, number of leaves, root length, and root wet weight. Giving Rootone F solution to sungkai stem cuttings at a concentration of 80 grams and immersion for 24 hours gave the best effect.

PGPR (Plant Growth Promoting Rhizobacteria) is a substance that helps plant growth with the help of rhizosphere microorganisms. PGPR propagation can be done with liquid media. This PGPR propagation needs to be done because this substance has many benefits for agricultural cultivation. The application of PGPR to the test plant, namely the pakcoy plant, proved that there was an effect of giving PGPR to the plant. Observations on the test plants were carried out by observing several observation variables such as plant height, root length, number of leaves, wet weight and dry weight. The results of these observations showed that the effect on the test plants was seen in the variables of root length, wet weight, and dry weight. Meanwhile, the variable plant height and number of leaves did not show a visible difference.

In vitro cultivation is a highly important biotechnological method widely used for the production of orchid seedlings, but it is necessary to study the suitability of the nutrients used in different kinds of formulation, as the nutritional requirement varies according to the species. The objective was to evaluate different concentrations of iron in the in vitro cultivation of Schomburgkia crispa Lindl seedlings. Seedlings were obtained from seeds germinated in vitro. Modified MS culture medium was used with half of the macronutrient concentration. The micronutrients were added according to the original formulation, except for the iron which was added from a stock solution of FeEDTA (FeSO4.7H2O: 5.6 g L-1 and EDTA: 7.48 g L-1) at 0.0; 2.5; 5.0; 7.5; 10.0 and 12.5mL L-1. At 200 days after seedling transplantation, shoot height, root length, number of leaves, shoot number, leaf length, leaf width, aerial and root dry mass, chlorophyll a, b and carotenoids content were evaluated. A completely randomized design was used, with six treatments and ten replicates of five seedlings. Regression analysis was performed at 5% of significance. The increase in iron concentration caused a reduction in root length and an increase in the number of leaves and shoots. The concentration of 4.13 mL L-1 of FeEDTA was the one that provided the best in vitro growth of S. crispa plants. High concentrations of iron caused a reduction of initial development, but stimulated an increase in the number of shoots.

A pot experiment was conducted to observe the effect of indigenous strains of rhizobacteria isolated from litchi orchards of East Champaran, Bihar (India) on the growth and survivability of litchi seedlings. Three efficient native rhizobacterial isolates belonging to genera Pseudomonas, Azotobacter and Ochrobactrum were used in seven different combinations and their effect on germination rate, shoot height, root length, number of leaves were observed and recorded in litchi seedlings. Pot 7 containing mixed combination of all the three isolates in equal proportion showed maximum root length (11.7 cm) and shoot length (12.5 cm), early germination as compared to control Pot P8 devoid of any isolates. Pot 4 (Pseudomonas + Azotobacter) and pot 5 (Pseudomonas + Ochrobactrum) also gave satisfactory result in all the parameters recorded. The results clearly state that, mixture of all the three rhizobacterial isolates as “Biomix” produced stimulatory growth results on litchi seedlings as compared to sole application and control. This “Biomix” could be used for formulating effective biofertilizers for litchi orchards in future.
