Abstrak (Berisi Bastraknya saja, Judul dan Nama Tidak Boleh di Masukan)

Penelitian dilaksanakan di Laboratorium Benih dan Laboratorium Lapang Terpadu Fakultas Pertanian Universitas Lampung pada awal Agustus 2020 sampai awal Januari 2021 menggunakan 22 genotipe benih kenari (Canarium indicum L.) asal Maluku Utara. Percobaan I: Keragaman fisik benih beberapa genotipe kenari (Canarium indicum L.) asal Maluku Utara dengan pengamatan karakter morfologi benih, pengukuran dilakukan pada karakter kuantitatif dengan alat ukur dan karakter kualitatif dengan cara skoring. Pengukuran dilakukan berdasarkan Descriptors for walnut (1994) dimodifikasi dan khususnya benih. Percobaan II: Evaluasi viabilitas benih beberapa genotipe kenari dengan perlakuan perendaman air panas menggunakan Rancangan Acak Kelompok (RAK) Faktorial tiga ulangan dan dua faktor yaitu faktor pertama waktu perendaman air panas (tanpa perlakuan, 10 menit, dan 30 menit) dan faktor kedua 22 genotipe kenari. Percobaan III: Uji berbagai media untuk pertumbuhan bibit beberapa genotipe kenari (Canarium indicum L.) metode yang digunakan RAK-F terdiri dari dua faktor yaitu faktor media tanam (A) : media tanah Top soil, media tanah Top soil+ pupuk kotoran sapi (1:1) dan Cocopeat. faktor kedua 22 genotipe bibit kenari (G). Hasil penelitian Percobaan I: Hasil dendogram analisis UPMGA 22 genotipe berdasarkan 14 karakter morfologi dan agronomi memiliki persamaan ciri terdekat dalam hubungan kekerabatan yaitu genotipe Nge susara dan Nge jingga dengan nilai jarak koefisien sebesar 73,20 %. Sebaliknya hubungan kekerabatan terjauh berdasarkan kesamaan ciri yaitu genotipe Ifa daalus dengan Ifa wagol nilai jarak koefisien sebesar 22,04%. Percobaan II: genotipe G4 (Ifa maidetibo) memiliki nilai tertinggi pada variabel nilai delta, keberhasilan persemaian, kecepatan berkecambah, daya kecambah, tinggi kecambah, diameter kecambah dan jumlah daun pada perendaman 10 menit. Selanjutnya pada bobot batang basah, bobot batang kering, bobot daun basah, bobot daun kering, jumlah akar, bobot akar basah dan bobot akar kering perendaman 10 menit merupakan perlakuan terbaik. Percobaan III: genotipe G21 memiliki tinggi bibit tertinggi pada umur 5-20 HSTP, sedangkan umur 25 sampai 70 HSTP genotipe G20 pada media tanam tanah top soil + pupuk kotoran sapi yang tertinggi. Selanjutnya jumlah daun tertinggi pada umur 5 sampai 35 HSTP terdapat pada genotipe G4, sedangkan umur 40, 45 dan 70 HSTP genotipe G8. Selanjutnya genotipe G14 memiliki jumlah daun tertinggi pada umur 50 dan 55 HSTP, sedangkan umur 60 dan 65 HSTP jumlah daun tertinggi pada genotipe G9 media tanam tanah top soil + pupuk kotoran sapi. Diameter bibit tertinggi pada umur 5 sampai 70 HSTP terdapat pada genotipe G4. Kata Kunci : 22 genotipe benih kenari, perendaman, media tanam, agronomi, morfologi, bibit kenari, tanah top soil, cocopeat, pupuk kotoran sapi. The research was carried out at the Seed Laboratory and Integrated Field Laboratory, Faculty of Agriculture in University of Lampung from early August 2020 to early January 2021 using 22 genotypes of walnut (Canarium indicum L.) seeds from North Maluku. Experiment I: The physical diversity of seeds of several genotypes of walnut (Canarium indicum L.) from North Maluku by observing the morphology of the seed morphology. Measurements were made on quantitative characters using measuring instruments and qualitative characters. Measurements were made based on the modified Descriptors for walnut (1994) and particularly for seeds. Experiment II: Evaluation of seed viability of several walnut genotypes with hot water immersion treatment using a randomized block design (RAK) Factorial three replications and two factors, namely the first factor was hot water immersion time (without treatment (control), 10 minutes, 30 minutes) and the second factor 22 walnut genotypes. Experiment III: Test various media for seedling growth of several genotypes of walnut (Canarium indicum L.) The method used RAK-F consists of two factors, namely the first factor is planting media (A): soil media (control), soil media + cow dung fertilizer ( 1:1), Cocopeat and the second factor of walnut seed genotype (G). Research results Experiment I: The results of the UPMGA dendogram analysis of 22 genotypes based on 14 morphological and agronomic characters have the closest similarity in kinship characteristics, namely the genotypes of Nge susara and Nge jingga with a distance coefficient value of 73.20%. On the other hand, the farthest kinship based on the similarity of characteristics is the genotype Ifa daalus with Ifa wagol with a distance coefficient value of 22.04%. Experiment II: genotype G4 (Ifa maidetibo) had the highest value on the variables of delta value, nursery success, germination speed, germination, germination height, sprout diameter and number of leaves at 10 minutes immersion. Furthermore, on wet stem weight, dry stem weight, wet leaf weight, dry leaf weight, number of roots, wet root weight and dry root weight soaking for 10 minutes was the best treatment. Experiment III: genotype G21 had the highest seedling height at the age of 5-20 HSTP, while at the age of 25 to 70 HSTP genotype G20 in planting media of top soil + cow dung was the highest. Furthermore, the highest number of leaves at the age of 5 to 35 HSTP was found in the G4 genotype, while at the age of 40, 45 and 70 HSTP the G8 genotype. Furthermore, genotype G14 had the highest number of leaves at the age of 50 and 55 HSTP, while at the age of 60 and 65 HSTP the highest number of leaves was at genotype G9 with top soil + cow dung growing media. The highest seedling diameter at the age of 5 to 70 HSTP was found in the G4 genotype. Keywords: 22 genotypes of walnut seeds, immersion, planting media, agronomy, morphology, walnut seeds, top soil, cocopeat, cow manure.
