Abstract

Mahagony is one of plants that could fill the needs of wood in Indonesia. The need of wood recently reached 10 million m3 per year. Basically Mahagony plants were very well associated with endomycorrhizal, but there was study that showed the Mahagony plants were able to associated with ectomycorrhizae spore. The aims of this studied were to determine the effected of ectomycorrhizae on Mahagony plant seedlings and the best dose of ectomycorrhyzae inoculation to improved the growth of Mahagony plants. This study was carried out in the greenhouse of the Faculty of Agriculture, University of Lampung on October 2017 - March 2018. The method used is completely randomized design with 4 treatments, 5 replications and 5 units of each experimental unit so that the entire plant amount were 100 experimental units. The dosage applied in this research were 0 ml/polybag, 10 ml / polybag, 20 ml / polybag and 30 ml / polybag. Parameters observed in this study were leaf area, height, diameter, number of leaves, root length, percentage of colonization, and dry weight. The research data obtained then analyzed using a homogenity test, Bartlett test and then proceed with smallest real difference test. The results showed that giving of ectomycorrhizae at a dose of 20 ml/polybag and 30 ml/polybag significantly affected to have higher percentage of colonization than the dose of 10 ml/polybag which is equal 0.67% to 0.84%. In leaf area parameter, the application of ectomycorrhizae with dossages of 30 ml.polybag, significantly showed the lowest leaf area compare to other treatments. It conclude that mahagony plants were not compatible with ectomycorrhizae there for percentage of inoculation in mahagony plants seeds was low and could not help plant grow.

Abstract

Kondisi lahan yang kritis merupakan masalah yang banyak ditemukan dalam upaya pengembangan hutan tanaman.Permasalahan ini dapat ditangani dengan menggunakan bahan bahan pembenah tanah yang alami seperti mikoriza dan asam humat.Penelitian ini dilakukan untuk melihat pengaruh penambahan mikoriza jenis Scleroderma sp dan asam humat terhadap pertumbuhan semai Merbau.Penelitian ini diacak menggunakansusunan RAL Faktorial, yang terdiri dari dua faktor, yaitu konsentrasi asam humat dan dosis Scleroderma sp. Dosis Scleroderma sp yang digunakan sebanyak  0 ml dan 20 ml, sedangkan konsentrasi asam humat yang digunakan sebanyak 0 ppm, 1500 ppm, 2000 ppm dan 2500ppm. Data yang diperoleh kemudian dianalisis menggunakan analisis varian dan dilanjutkan dengan uji Duncan.Penelitian ini menunjukkan pengaruh aplikasi asam humat yang  secara nyata meningkatkan tinggi, diameter, dan berat kering total semai merbau. Inokulasi mikoriza secara nyata meningkatkan diameter dan berat kering total.Sedangkan interaksi asam humat dan mikoriza secara nyata meningkatkan persen kolonisasi, luas daun, berat kering pucuk, dan panjang akar.Penambahan asam humat 2000 ppm dan mikoriza 20 ml memberikan nilai terbaik untuk pertumbuhan semai merbau dan kolonisasi mikoriza.

Abstract

Community forest of Bina Wana is one of the forest areas in West Lampung which is divided into three land covers namely primary forest, agroforestry, and annual crops. The differences amoung the land cover affect the ecological role, therefore it is important to figour out the carbon stock in order to determine the potential of environmental services. The purpose of the study was to find out the important values index and carbon stock in community forest of Bina Wana. Sampling was taken using the cluster sampling method based on differences in land cover classes. Carbon stock was estimeted by using allometric equations and biomass calculation. The result of the research showed that the highest important values index in primary forest for tree phase was Joho (Terminalia bellirica) (53,35%), for pole phase (24,23%), sapling (171,18%) and understorey (67,08%), namely Tenam species (Shorea platiclados).  The highest important values index on agroforestry was Cempaka (Michelia champaca) (54,37%) to tree, Pulai (Alstonia scholaris) (120,48%) to pole, Coffee (Coffea canephora) (214,45%) to sapling, and Wedusan (Ageratum conyzoide) (105,68%) to understorey. As with the annual crop land, only rice plants (Oryza sativa) (200%) were found in the understorey phase. The average carbon stock for primary forest were (284,15 tons / ha), agroforestry (74,89 tons / ha) and annual crops (1.42 tons / ha) with total carbon stock of fore whole area was (360,46 tons / ha)
