Abstract

Jumlah buah muda per dompol menentukan tingkat persaingan antar buah dalam mendapatkan fotosintat.Tingkat persaingan tersebut akan berpengaruh terhadap pertumbuhan, kerontokan, dan kandungan nutrisi buahdalam suatu dompol. Tujuan penelitian adalahuntuk mengkaji pengaruh jumlah buah muda terhadap diameterbuah, bobot per buah, kerontokan buah, dan kandungan gula dan vitamin C.Penelitian surve ini menggunakantanaman jeruk yang berumur 3 tahun. Lokasi penelitian di Desa Karangdadap, Kecamatan Kalibagor, KabupatenBanyumas dengan ketinggian tempat sekitar 45 mdpl.Faktor yang diteliti adalah jumlah buah muda per dompol(1, 2, dan 3 buah). Perlakuan tersebut diulang 3 kali dalam setiap pohon, jumlah pohon yang diteliti sebanyak 10batang dari 12 pohon jeruk yang ada di lokasi penelitian. Variabel yang diamati meliputi jumlah buah retensi danbuah rontok per dompol,diameter buah, bobot per buah, kandungan gula, dan kandungan vitamin C. Hasilpenelitian menunjukkan bahwa antar jumlah buah muda per dompol yang diteliti tidak menunjukkan pengaruhterhadap diameter buah, bobot per buah, kerontokan buah, kandungan gula, dan kandungan vitamin C buah jeruk.Kerontokan buah jeruk untuk setiap dompol yang berisi 1 buah, 2 buah, dan 3 buah masing-masing mulai terjadi140, 70, dan 80 hari setelah fruitset; sedangkan tingkat kerontokannya adalah 4,0%, 13,0%, dan 14,7%Kata kunci: dompol, kerontokan, kandungan gula, vitamin CABSTRACTNumber of young fruits per cluster determine the competition level among fruits for getting photosynthate.This competition level influence growth, fruit drop, and nutrition content of fruit. The objective of this researchwas to study the effect of number of young fruits on fruit diameter, weight per fruit, fruit drop, and content ofglucose and ascorbic acid. Research used 3 years old orange tree of local variety. It was located at Karangdadapvillage, Kalibagor district, and Banyumas regency with about 45m asl altitude. The treatment was 3 levels ofnumber of young fruit per cluster : 1, 2, and 3. The observed variables were number of fruit drop and fruit retentionper cluster, fruit diameter, weight per fruit, content of glucose and ascorbic acid. The results of research showedthat number of young fruit did not influence fruit diameter, weight per fruit, fruit drop, content of sucrose andascorbic acid. Fruit drop of cluster having 1, 2, and 3 young fruits were occurred at 140, 70, and 80 days afterfruitset respectively and its level were 4,0%; 13,0%, and 14,7%.Keywords : cluster, fruit drop, content of glucose and ascorbic acid.

Abstract

Fruit drop potentially decreases the yield of durian, so it needs to be controlled. Its control canbe done better when information on pattern of fruit drop is available. This research examined fruit dropof different panicle positions of two durian varieties. Observed panicle positions i.e. bottom, central,and upper of a tree, observed varieties i.e. Kani, Monthong. Observed variables were percentage offlowery branch, number of flower panicle, total number of flowers, number of flowers per panicle, andfruit set. The objective of this research was to know the pattern of fruit drop and flowering of differentpanicle positions of two varieties of durian. The result of research showed that Kani had higher observedvariables than Monthong. Upper position of panicle had higher number of flower panicles and fruit setscompared to the other panicle positions. The highest total number of flowers was showed by panicle atupper position of Kani treeKey words: durian, panicle, fruit drop, Kani, Monthong ABSTRAKKerontokan buah berpotensi mengurangi hasil buah durian sehingga perlu dikendalikan.Pengendaliannyadapat dilakukan dengan baik apabila terlebih dulu diketahui pola kerontokan buahnya.Penelitian ini mengkajikerontokan buah pada dompol yang berbeda posisinya pada suatu pohon dari dua varietas durian. Posisi dompolyang diteliti yaitu bawah, tengah, dan atas pada suatu pohon, sedangkan varietas yang diteliti adalah Kani danMonthong. Variabel yang diamati meliputi persentase cabang berbunga, jumlah dompol bunga, jumlah bunga total,jumlah bunga per dompol, dan jumlah buah terbentuk.Penelitian bertujuan untuk mengetahui pola kerontokanbuah dan pembungaandari dompol yang berada pada posisi berbeda dua varietas durian. Hasil penelitianmenunjukkan bahwa Kani menghasilkan variabel pengamatan yang lebih tinggi dibandingkan Monthong.Dompolyang berada padaposisi atas dari suatu pohon menghasilkan jumlah dompol bunga dan jumlah buah terbentuk yanglebih tinggi dibandingkan posisi dompol lainnya. Jumlah bunga total tertinggi ditunjukkan oleh dompol yangberada pada posisi atas varietas Kani.Kata kunci: durian, dompol, kerontokan buah, Kani, Monthong

Abstract

Chrysanthemum is a strategic floriculture commodity to be developed. The growth and production of flowers is influenced by many factors including growing media and fertilization. This study aims to examine the effect of variations in planting media and concentrations of foliar fertilizer on the growth and yield of chrysanthemum. The study was conducted in a Completely Randomized Block Design with three replications. Treatment of planting media consisted of cow manure: husk charcoal: bamboo leaf humus (1:1:1), cow manure: husk charcoal: cocopeat (1:1:1), and cow manure: husk charcoal. : wood sawdust compost (1:1:1). Treatment of foliar fertilizer concentrations consisted of control (0 g/l); 2 g/l; 4 g/l; and 6 g/l. The data obtained were analyzed using the F test, if there was a significant variation, then proceed with the DMRT test at ? 5%. The results showed that the planting media treatment of cow manure: husk charcoal: bamboo leaf humus, had a better effect than other media, indicated by the variables of plant height, crown diameter, stem diameter, number of branches, number of flowers, flower diameter, flower initiation time, flower coloring time, and harvest time. The application of foliar fertilizer with doses of 6 g/l, 4 g/l, and 2 g/l gave higher yields of flowers than the control. A good combination treatment for flower yields was found in the combination of cow manure: husk charcoal: bamboo leaf humus planting media and leaf fertilizer concentration of 4 g/l which produced the highest number of flowers, while for growth was the combination of cow manure : husk charcoal: bamboo leaf humus planting media and leaf fertilizer concentration 2 g/l; cow manure: husk charcoal: cocopeat and leaf fertilizer concentration of 4 g/l; as well as cow manure: husk charcoal: cocopeat and the concentration of foliar fertilizer 6 g/l which gave the higher number of leaves.
