Coastal Shorelines

The study site is currently retreating at a rate of 20 m y−1due to severe coastal erosion and found to be highly polluted as revealed from the water, sediment and biological analysis. In an attempt to prevent coastal erosion, 14,000Rhizophora mucronata(RM) trees were planted across a heavily eroded shoreline at Samut Sakhon, Thailand. The survival rate of RM was high at the landward area and decreased at the offshore area. The most landward plot showed the highest survival rate when measured 4 years after planting (63.5%), while only 26.7% of trees survived at the most offshore plot. NPK and coconut fiber were shown to be significantly effective to enhance initial tree growths in heavily eroded area.

Reintroduction of once existing red mangrove, Rhizophora mucronata trials were carried out in Abu Dhabi, United Arab Emirates. Propagules were procured from Pakistan and cultured in a greenhouse before they were planted alongside existing Avicennia marina forest in two sites of Abu Dhabi emirate, Abu Al Abyad and Ras Ghanada Islands. This study documents the present condition of the plants after 11 years of plantation. Long term survival rate was as high as 81% in Abu Al Abyad while Ras Ghanada experienced a very low survival rate at 10%, primarily due to external factors. In contrast, Ras Ghanada plants showed higher growth with the mean height stands at 2.06 m (SD ± 0.31m), while in Abu Al Abyad it is 1.53 m (SD ± 0.36 m). In Abu Al Abyad, more than one third (36.4%) of surviving plants showed reproductive phenology, whereas in Ras Ghanada it was only 10.3%, despite of greater height classes. Many Rhizophora were also noticed with well-developed stilt roots. This study showed that Rhizophora mucronata can be planted in Abu Dhabi, despite the Emirate's harsh climatic conditions.

Guludan technique becomes an alternative for mangrove rehabilitation in the disused fishponds. This technique has been implemented since 2005 on the coast of Jakarta. The wider application of this technique requires several studies in advance to see growth of the mangrove in the already planted guludan. This study aims to measure the growth of mangroves planted by guludan techniques, identify environmental factors that affect their mangrove growth, and analyze their relationship. Measurements were performed on 40 guludan samples which planted by Rhizopora mucronata in 2010 - 2013. Rhizopora mucronata grew well in the guludans, followed by Sonneratia caseolaris that grew naturally. Both were dominated by individuals in sapling phase. Meanwhile, environmental factors affecting mangrove growth were N-total, P, Mg, Ca, Na, clay texture, CEC, soil salinity, soil pH, and water level in the guludan.Keywords: guludan technique, mangrove rehabilitation, Rhizophora mucronata, Sonneratia caseolaris

Bruguiera gymnorrhiza is a mangrove species that can be used to rehabilitate mangrove forest. The information about the response of mangrove seedlings to the factors that affect its growth is needed to ensure its survival rate. This study aimed to examine the response of Bruguiera gymnorrhiza seedlings to the factors that affect its growth such as media and shade level. This research used a Completely Randomized Factorial Design (CRFD) with the treatments of growing media (A) and shade level (N) of 3 levels on each factor, that are mud (A0); mud and compost (A1); and mud, compost, sand (A2); also 0% shade (N0); 50% shade (N1); and 70% shade (N2) on the 3 months old seedlings. The results showed that the treatment of shade level significantly affected the growth response of B. gymnorrhiza seedlings, while the treatment of growing media and interaction of both treatments did not show a significant response. The 0% shade level gave the best growth response of B. gymnorrhiza seedlings. Keywords: Growth rate, light level, mangrove, rehabilitation, seedbed

Grafting is the most widespread vegetative propagation technique in cashew tree (Anacardium occidentale L.). Usually, cashew plant grafting are done on seedlings in plastic bags in nursery. In addition, to the low success rate, grafted plants have a low viability rate in field because main roots were broken during their transfer to the field. This study was carried out to evaluate the grafting success and survival rate of cashew seedlings planted in root trainer with different size (250 cc, 500 cc and 1000 cc). Each type of container was filled with two different growing substrates: coconut fiber and sawdust. Results showed that large size root trainers (1000 cc) have the highest percentage of graft success (96.67%). Rootstocks 45 days old presented the highest percentage of graft success in nursery (94.31%). The longest scions (12 cm) presented the minimum sprouting time (18.21 days). In the field, survival rate 100% of the grafted plants was recorded. In addition to the high survival rate ensured in field, root trainer is eco-friendly reusable and it light nature can prove a profitable technology for raising cashew elite plants regeneration.

The study was conducted to evaluate success indicators of the Philippine National Aquasilviculture Program (PNAP) – Mangrove Rehabilitation Project in Davao del Sur. The growth increment of mangroves(cm/day) and survival and the physico-chemical parameters of the different project sites were recorded. A questionnaire was employed to gather in socio-demographic profile, best practices employed, benefits and institutional factors. The study employed one shot sampling. The growth increments of mangroves in Punta Biao (0.0032 cm/day) was comparable with Bucana (0.0031 cm/day) but were significantly higher than the rest of the project sites.Sto. Rosario exhibited the lowest growth increment of 0.0007 cm/day. In terms of survival, Bucana and Punta Biao showed the highest survival rate of 96.87% and 99.62%respectively, while San Isidro obtained the lowest mean value of 13.71%. Two (2) types of area orientation found in the different project sites, midland and tidal/mud flats. Soil types were clay loam and sandy clay. High survival and high growth increment were observed in midland area with clay loam substrate while low survival observed in seaward areas with sandy clay substrate. The pH ranged from 6.46-7.23 while salinity ranged from 23ppt-35ppt.  Some of the contributing factors that influenced higher survival rate of PNAP Mangrove Rehabilitation Project in Davao del Sur include the used of matured mangrove propagates, staking prior to mangrove planting, regular monitoring at least every other day and carefully scraping epiphytes (e.g. barnacles and oysters) during mangrove’s early stage. This practices observed in all project sites regardless of percentage rate recorded.

ABSTRACT: Hippeastrum spp. are herbaceous species belonging to the family Amaryllidaceae, widely marketed worldwide as indoor plants. Aiming to characterize chemically and physically and to compare five substrates in acclimatization, micropropagated seedlings of Hippeastrum reticulatum var. striatifolium (Herb), with an average of four roots, two leaves and bulbs with a 4.7mm diameter, were transplanted to 50-cell polyethylene trays each containing the following substrates: T1 - vermiculite, T2 - carbonized rice husk (CRH), T3 - commercial (peat + vermiculite + CRH), T4 - coconut fiber, and T5 - composted Pinus bark. After transplantation, the trays were kept for 17 days at a greenhouse with intermittent irrigation by nebulization, and 80 days at a greenhouse on a bench with intermittent irrigation by capillarity. The experimental design was randomized blocks with seven replications and ten seedlings per plot. The acclimatization of seedlings was efficient for the substrates tested despite the differences verified by chemical and physical characterization. The mean survival rate was 96%. However, seedlings acclimatized in the T5 substrate showed a qualitative improvement due to a higher formation of roots, leaves and fresh matter.

For the implementation of commercial cultivation areas of heliconias, it is important to use pathogen-free seedlings and maintain the inherent characteristics of the hybrid plants to be cultivated. Thus, the objective of this work was to study a protocol for the in vitro propagation of the Heliconia bihai x Heliconia caribaea 'Jacquinii' hybrid and evaluate the plants survival rate during the acclimatization stage. Buds (explants) up to 5 mm long, originated from plantlets established in vitro were transferred to a ½ MS culture medium added by 0,5 mg L-1 of NAA combined with concentrations of 0.0; 0.5; 1.0; 1.5; 2.0 and 2.5 mg L-1 of 6-BA. Each treatment included 10 replications with one explant by replication, distributed at completely randomized design. After 100 days of growth under controlled conditions, rate of multiplication; plantlets length (cm) and cluster fresh and dry weight (g) were evaluated. Remaining plantlets were acclimatized in coconut fiber substrate to assess survival rate. In regards to the number of buds, the largest number of buds (four buds per explant) was verified in the absence of 6-BA, whereas in the presence of 6-BA, two to three buds per explant were observed. No significant differences were observed among 6-BA concentrations for plantlets length and cluster fresh weight. Plantlets survival rate during the acclimatization stage was 100%. Results from this study show that the MS culture medium added by 0.5 mg L-1 of NAA can be used for the in vitro propagation of the H. bihai x H. caribaea 'Jacquinii' hybrid

This study aims to determine the effectiveness of Rhizophora Mucronata’s bark extract in curing Vibrio harveyi infection in nile tilapia fish by challenge testing (in vivo test). It was conducted in October 2018-May 2019 at the Central Laboratory of Universitas Padjadjaran and Building-4 of Aquaculture and Hatchery Laboratory in the Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran. This research used microdilution method to determine the Minimum Inhibitory Concentration (MIC) value of R.mucronata’s bark extracts and laboratory experimental method with a Completely Randomized Design (CRD) model for challenge testing (in vivo) which consisted of 5 treatments and 3 replicates where the given treatment varied in concentrations. These various concentrations that were given started from A (0 ppm / control), B (16 ppm), C (32 ppm), D (48 ppm), and E (64 ppm). The observed parameters were inhibitory antibacterial activity for MIC and survival rate, as well as clinical symptoms and water quality for the challenge test. Survival Rate data of nile tilapia seedlings was analyzed by regression analysis. The observation results of MIC, MBC values, clinical symptoms and water quality were analyzed descriptively. The results showed the Minimum Inhibitory Concentration value of R.mucronata bark extract at a concentration of 6,250 ppm while its Minimum Bacteriocidal Concentration value at 50,000 ppm. The fish tolerance test results towards the extract (LC50 test) is 64 ppm. Differences in treatment produced results that have significant effects on survival rate. The use of Rhizophora Mucronata bark extract at a dose of 64 ppm resulted in the highest survival rate of Nile tilapia fish as high as 76.66%.
