Pengaruh Lama Perendaman Dan Konsentrasi Kalium Nitrat (KNO3) Terhadap Pematahan Masa Dormansi Biji Kopi Robusta (Coffea canephora)
نویسندگان
چکیده
Pembibitan kopi sering dihadapkan dengan masa dormansi biji yang disebabkan oleh kulit ari keras. Kalium nitrat (KNO3) dapat melunakkan dan mempermudah air masuk ke dalam biji, sehingga mempercepat proses metabolisme. Penelitian ini bertujuan untuk mengetahui pengaruh lama perendaman konsentrasi kalium terhadap pematahan robusta. Rancangan penelitian menggunakan Acak Lengkap Faktorial (RAL-F), faktor pertama (L) terdiri atas tiga taraf meliputi 12 jam (L1), 24 (L2), 36 (L3) kedua KNO3 (K) 4 0% (K0), 0.5% (K1), 1.0% (K2) 1.5% (K3). Faktor berpengaruh nyata kecambah normal (biji), abnormal daya berkecambah (%), potensi tumbuh maksimum waktu (hr). (%) Hasil menunjukkan bahwa terdapat interaksi antara efektivitas robusta.Kata kunci : dormansi, perendaman, konsentrasi, nitrat,

Determination Of Coffee Content In Coffee Mixtures
The Malaysian Food Regulations 1985 [1] states that coffee mixtures must contain not less than 50 percent coffee. Caffeine content of a coffee mixture is usually used to indicate its coffee level. In this study, coffee content of coffee mixtures was determined based on caffeine concentrations using High Performance Liquid Chromatography (HPLC). Caffeine recoveries from spiked standard coffee mi...
متن کاملIdentification and Analysis of Jasmonate Pathway Genes in Coffea canephora (Robusta Coffee) by In Silico Approach
BACKGROUND Coffea canephora is the commonly cultivated coffee species in the world along with Coffea arabica. Different pests and pathogens affect the production and quality of the coffee. Jasmonic acid (JA) is a plant hormone which plays an important role in plants growth, development, and defense mechanisms, particularly against insect pests. The key enzymes involved in the production of JA a...
متن کاملDevelopment of Genic and Genomic SSR Markers of Robusta Coffee (Coffea canephora Pierre Ex A. Froehner)
Coffee breeding and improvement efforts can be greatly facilitated by availability of a large repository of simple sequence repeats (SSRs) based microsatellite markers, which provides efficiency and high-resolution in genetic analyses. This study was aimed to improve SSR availability in coffee by developing new genic-/genomic-SSR markers using in-silico bioinformatics and streptavidin-biotin ba...

BACKGROUND AND AIMS Dehydrins, or group 2 late embryogenic abundant proteins (LEA), are hydrophilic Gly-rich proteins that are induced in vegetative tissues in response to dehydration, elevated salt, and low temperature, in addition to being expressed during the late stages of seed maturation. With the aim of characterizing and studying genes involved in osmotic stress tolerance in coffee, seve...
