Abstract

Aluminum (Al) is one of the problems and is a factor inhibiting plant growth on soils with acidic pH. This study aims to examine the growth response of Eucalyptus pellita and Eucalypus Deglupta seedlings to Al exposure. This study used a completely randomized design (CRD) with one factor, where the Al concentration consisted of 5 levels, namely: 0 mM (control), 2 mM, 4 mM, 6 mM, and 8 mM with 3 repetitions each and each repetition consisted of 3 units of the plant. The results showed that Al treatment had a significant effect on the growth parameters of both plant types, except for the root dry weight parameter for E. deglupta. Increasing the Al concentration can reduce almost all growth parameters. The 4 mM Al concentration was able to increase the height growth, plant dry weight (roots and shoots), and tolerance index for the E. pellita species, while the Al 2 mM concentration was able to increase the root growth of E. deglupta plants. Almost all growth parameters for E. pellita species were higher than that of E. deglupta, except for the SPAD chlorophyll index. The concentrations of 6 mM and 8 mM were toxic to E. pellita and E. deglupta.

Abstract

The success of revegetation in the context of forest land rehabilitation and post-mining land reclamation is often often caused by constraints due to marginal land conditions, such as high acidity/alkalineity, low organic matter content, and low availability of macro nutrients. Mycorrhiza Biofertilizer (MB) is one alternative technology that has been reported to be able to increase the success of the rehabilitation. Forest farmers, as one of the actors in forest rehabilitation activities, do not yet have sufficient knowledge and skills in developing biofertilizer such as MB. The objectives of theis community services were to introduce and improve forest farmer about the MB, as well as to establish the demonstration plot for MB development. The result showed that field training and counseling on mycorrhiza and its benefits, as well as the manufacture of mycorrhizal biofertilizers have been carried out in Cisangku, Malasari village, Bogor Regency involving Forest Farmers Model Conservation Village (KTH MKK). The counseling and training were attended by 25 forest farmer participants. Based on the postest carried out after the implementation of counseling and training, there was an increase in farmers' knowledge about mycorrhizal and its benefits as well as procedures for developing mycorrhizal fertilizers. The participants wer also satisfied and increased their skill in preparing mycorrhizal culture materials and caring for their selves. The participating farmers were even willing to develop MB independently if they have sufficient skills and know the benefits. The increasing knowledge and skills of forest farmers had an impact on improving the quality of forest farmers in supporting forest rehabilitation and becomes an alternative of additional income.

Abstract

Sengon (Falcataria falcata) is one of the fast-growing forestry species with high economic value and is widely cultivated in Indonesia. However, a major challenge often encountered is the decline in seed viability and vigor during storage. To address this issue, biopriming technology using dark septate endophytes (DSE) fungi was applied as an invigoration method to improve the physiological quality of seeds.This study aimed to determine the effect of biopriming technology using DSE fungi on the viability and vigor of sengon seeds. The experimental design used was a Completely Randomized Design (CRD) with three treatments, namely without DSE (control), DSE isolate CPGS 3, and DSE isolate S-115, each replicated four times. The observed parameters included germination percentage, germination rate, germination speed index, vigor index, uniformity of germination, and seedling growth rate. Data were analyzed using analysis of variance (ANOVA), followed by Duncan’s Multiple Range Test (DMRT). The results of the study showed that the DSE CPGHS-3 and DSE S-115 treatments had a significant effect (p<0.05) on the parameters of Germination Power (88-89%) and Seed Growth Rate (8-9%/etmal), but no significant effect (p>0.05) on other seed vigor parameters, such as Germination Rate, Germination Rate Index, Vigor Index, and Seed Growth Simultaneity. The DSE CPGHS-3 strain tended to have a positive impact in the form of an increase in almost all vigor parameters, except for Seed Growth Rate which was constant. Meanwhile, DSE S-115 had a varying effect with a decrease in seed vigor on the Vigor Index and Seed Growth Simultaneity parameters compared to the control. The application of DSE as a biopriming agent to improve seed physiology needs to pay attention to the compatibility between the DSE strain and the type of plant seed.
