“…Further, the role of cytokinin is in spurring root growth, especially by stimulating the differentiation of root meristem cells [54], whereas the role of auxin has been reported as the central mediator of organ development by promoting cell division, cell extension, and cell differentiation [55]. Moreover, auxin has been proven to accelerate and improve the rooting percentage of the stem cuttings [56] while cytokinin according to Jonas et al [57] stimulates water uptake, promote cell division and organ development and auxin has the role in root initiation. Nasri et al [58] revealed that exogenous auxin applications may have an indirect influence by increasing the translocation rates and sugar movement to stem cuttings and promote root growth.…”

Mabolo (Diospyros discolor), which is an indigenous species locally known as Kamagong, is popularly called “iron-wood”. With over-exploitation, these species are now threatened and are becoming extinct. Hence, it is the only way to conserved and save this economically valuable species by using nursery techniques with appropriate pre-sowing treatments. Therefore, the present study was attempted to evaluate the effect of coconut water on pre-sowing treatments additive on seed germination and initial growth performance of Kamagong (D. discolor). The seeds were extracted and subjected to the following treatments for 12 hours: Soaking in 100% water which is the control (T1), soaking with 50% of coconut water and 50% water (T2), and soaking in 100% coconut water (T3). The results showed that T3 had the highest germination mean value (78.33%), mean seedling height (11.80 cm) and mean number of leaves (2.04). By contrast, T2 (50% coconut water + 50% water) obtained the least germination mean value (76.67%), mean seedling height (11.63 cm) and mean number of leaves (2.00). However, there were no significant differences in the germination percentage, seedling height and number of leaves among all treatments at (p ≤ 0.05). The seeds subjected to T2 and T3 were significantly (p ≤ 0.05) better than seeds subjected to T1, having a mean root collar diameter (RCD) value of 3.98 mm, 3.75 mm and 3.48 mm, respectively. In terms of leaf measurements, the seedlings subjected to T2 and T3 had the highest leaf width value of 5.18 cm and 4.97 cm, respectively, whereas the seedlings subjected to T1 had the significantly lowest leaf width of 4.88 cm. Moreover, there was no significant effect among all treatments in terms of leaf and root length. Furthermore, it was observed in the study that fungal pathogens should also be taken into account as the pathogens are associated with the reduction of the germination percentage of the D. discolor seeds. Also, the study found out that seeds treated with 50% and 100% coconut water positively influenced the germination and initial seedling growth performance of D. discolor.

Setiawati T, Keliat APR, Budiono R, Partasasmita R, Iskandar J. 2018. Influence of NAA and coconut water with variation of soaking duration on the growth of yellow bamboo branch cutting. Nusantara Bioscience 10: 178-182. Yellow bamboo (Bambusa vulgaris Schrad Ex. var. Striata) is one kind of bamboo used for industrial and household raw materials. Yellow bamboo propagation with branch cuttings has relatively low percentage of growth. To increase the growing success of yellow bamboo branch cuttings can be used growth regulators substance, such as NAA and coconut water. This study aimed to obtain the best combination of NAA and coconut water with the soaking duration in the growth of yellow bamboo branch cuttings. The study was conducted using Completely Randomized Design (CRD) of 6 × 3 factorial arrangement with five replications. The first factor was the combination of NAA and coconut water (CW), which consisted of six levels, namely 100% CW, 20% NAA + 80% CW, 40% NAA + 60% CW, 60% NAA + 40% CW, 80% NAA + 20% CW and 100% NAA. The second factor was the soaking duration which consists of three levels, namely 12 h, 24 h, and 36 h. Parameters observed included shoot emerging time, shoot number, shoot length, leaf area, root number and root length. The data obtained were analyzed using the Analysis of Variance (ANOVA) and Duncan's Multiple Range Test (DMRT) α=5%. The results showed that the combination of 80% NAA + 20% CW gave the best yellow bamboo branch cuttings growth with an average shoot length of 1.44 cm, leaf area 41.29 cm2, root number 42.87 and root length 23.70 cm. The interaction of 80% NAA + 20% CW with soaking duration of 36 h resulted in average the fastest shoot emerging time of 2.02 days after planting.
