Abstract

Tulisan ini bertujuan untuk mengetahui variasi pertumbuhan dan daya pertunasan bibit meranti tembaga asal cabutan dari dua populasi dengan kondisi berbeda sebagai materi untuk pembuatan tanaman pangkas. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL) pola tersarang yang terdiri dari 2 faktor, yaitu asal populasi (Muara Wahau dan Berau, Kalimantan Timur) dan pohon induk (20 pohon induk dari Muara Wahau dan 14 pohon induk dari Berau). Dalam penelitian ini faktor pohon induk bersarang (nested) dalam faktor asal populasi. Hasil penelitian menunjukkan bahwa perlakuan asal populasi dan pohon induk berpengaruh sangat signifikan terhadap parameter  yang  diamati,  yaitu  tinggi,  diameter  batang,  jumlah  percabangan,  jumlah  tunas  dan  panjang  tunas. Populasi Muara Wahau menghasilkan rata-rata pertumbuhan tinggi, diameter batang, jumlah percabangan, jumlah tunas dan panjang tunas lebih baik dari populasi Berau. Bibit-bibit terbaik dalam pertumbuhan tinggi, diameter batang, jumlah percabangan, jumlah tunas dan panjang tunas didominasi oleh pohon induk dari populasi Muara Wahau.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh provenan dan komposisi media terhadap pertumbuhan stek pucuk pulai darat (Alstonia angustiloba Miq.) dengan teknik penunasan. Rancangan penelitian yang digunakan adalah Rancangan Acak Lengkap (RAL) yang disusun secara faktorial dengan 2 faktor, yaitu: provenan (Banten, Pendopo, Lubuk Linggau dan Solok) dan komposisi media (pasir, serbuk sabut kelapa, arang sekam, pasir : arang sekam (4:1) dan pasir : serbuk sabut kelapa (4:1)). Hasil penelitian menunjukkan bahwa interaksi perlakuan provenan dengan komposisi media tumbuh pengaruhnya tidak signifikan terhadap parameter pengamatan. Provenan Pendopo menghasilkan persen berakar (52,71%), jumlah akar (4,56 buah) dan panjang akar (2,40 cm) terbaik. Media pasir menghasilkan persen berakar (60,89%) dan jumlah akar (4,25 buah) terbaik. Media pasir : serbuk sabut kelapa (4:1) menghasilkan panjang akar (2,74 cm) terbaik.

Abstract

The aim of this experiment was to investigate effect of  media growth composition and NPK fertilizer dosage toward growth ability of A. angustoiloba from Pendopo Provenance, Muara Enim, South Sumatera. Completely Randomized Design of factorial with two factors (growth media composition and fertilizer dosage) and four levels of each factors were used. Four replications were used with five seedlings per replication. The effects of those treatments were evaluated through seedling height growth, stem diameter growth and number of leaves. The result showed that media composition variations gave very significant effect on height growth and number of leaves of  A. angustiloba seedling for 4 months. The best height growth was produced of top soil + compost (1:1) media (48,51 cm) and the best number of leaves was produced of top soil media (19,89). The fertilizer dosage variations gave very significant effect on height growth, stem diameter and number of leaves of  A. angustiloba seedling for 4 months. The best height growth (49,58 cm), stem diameter (5,93 mm) and number of leaves (20,24) were produced by 1 g NPK fertilizer dosage. Interaction of media composition and fertilizer dosage gave significant influence on height growth and stem diameter of  A. angustiloba seedling for 4 months.The best height growth (52,7 cm) was produced by interaction of top soil + compost (1:1) media and 1 g dosage of NPK fertilizer and the best stem diameter (6,5 mm) was produced  by interaction top soil and 0.5 g dosage of NPK fertilizer.

Abstract

The aim of this experiment was to investigate effect of population sources, media composition and NPK fertilizer dosage toward sprouting ability of Alstonia angustiloba Miq. Cutting. This experiment was arranged in completely randomized design with factorial setting. The research used 3 factors, I,e.population sources (banten, Pendopo, Lubuk Linggau and Solok); media compositions (top soil, top soil : Compost : husk charcoal 3 : 2 : 1, top soil : compost : husk charcoal 4 : 2 : 1, Top soil : compost :husk charcoal 5 : 2 : 1 and top soil : compost : husk charcoal 6 : 2 : 1) and NPK fertilizer dosage (0g,5 g. 10 g, 15 g and 20 g). The results showed that media composition variantions did not give significant effect on parameters measured. The best of length and diameter of sprouts, number of nodus and number of leaves were significantly produced by 20 g NPK fertilizer dosage. Pendopo popupation significantly produced the best length sprouts, while Banten population produced the best number of nodus and Lubuk Linggau population produced the best diameter sprouts and the highest number of sprouts. Interaction of NPK fertilizer dosage and population sources gave significant influence on number of sprouts, whit the best interaction was 10 g dosage of NPK fertilizer vs Lubuk Linggau population (1.79).
