<p>The use of young seed rhizomes became one of the obstacles in large white ginger (JPB) cultivation. Young ginger rhizomes rapidly shrank and decrease their viability. The experiment was aimed to study growth patterns, biochemical changes, and physiology of ginger plants to produce good quality rhizome seeds.  JPB rhizome seeds used were 9 months old, have been stored for 2 weeks after harvest, weighed 30-40 g with 2-3 buds, healthy, and given seed treatment. The rhizomes were planted in growth medium in polybags (60 cm x 60 cm). The study was conducted by direct observation, repeated 4 times, consisting of 50 plants per replication.  Observations were made on the plant growth patterns (plant height, stem length, tillers number, leaves number); rhizome development (fresh weight, branch rhizomes number, moisture content, and dry weight during growth); starch and hormonal content (IAA, gibberellin, ABA and cytokinin) of the rhizomes; and viability of rhizome seeds (growth rate, seed height, and dry weight). The results showed that the rhizomes of the 7-month-old ginger after planting (MAP) has entered the ripening phase, the rhizome morphology was optimal, and the starch content was not different from the rhizome seeds at 8 and 9 MAP. In addition, physiologically, the rhizome's growth potential was maximal (100%), growth rate (4.3% etmal<sup>-1</sup>), and seed height (33.8 cm) were better than 8 MAP (80%, 2.9% etmal<sup>-1</sup>, 33.7 cm) and 9 MAP (70%, 2.3% etmal<sup>-1</sup>, 29.4 cm).  This study indicated that ginger rhizomes harvested from 7 months old plants can be used for seeds.</p>

ABSTRAK<br />Kalium merupakan unsur hara yang paling banyak diserap oleh<br />tanaman jahe dibandingkan N dan P. Produktivitas tanaman akan menurun<br />apabila kekurangan unsur hara K, karena K mempunyai fungsi penting<br />pada proses fotosintesis, aktifitas enzim, metabolisme karbohidrat, protein<br />dan sebagai transport ion. Penelitian dilakukan di Kebun Percobaan<br />Sukamulya sejak Januari sampai Mei 2010. Tujuan penelitian ini adalah<br />untuk mengetahui pengaruh pemberian pupuk KCl terhadap pertumbuhan,<br />hasil, serapan hara, dan mutu rimpang jahe muda. Perlakuan disusun<br />dalam rancangan acak kelompok dan diulang 4 kali. Perlakuan yang<br />dicoba terdiri atas delapan perlakuan pupuk KCl yaitu; 0, 50, 100, 150,<br />200, 250, 300, dan 350 kg/ha. Jarak tanam yang digunakan adalah 50 x 60<br />cm, dengan populasi 100 tanaman/plot. Contoh tanaman diambil pada<br />umur 4 BST, sebanyak 5 tanaman setiap satuan perlakuan. Peubah yang<br />diamati adalah, tinggi tanaman, jumlah anakan, bobot segar rimpang,<br />bobot kering rimpang dan tanaman, kadar minyak atsiri, pati, serat, hara<br />N, P dan K. Hasil penelitian menunjukkan bahwa tinggi tanaman, bobot<br />segar rimpang, bobot kering batang+daun dan bobot kering rimpang<br />meningkat secara nyata dengan meningkatnya perlakuan pupuk KCl.<br />Tinggi tanaman, bobot segar rimpang, bobot kering batang+daun tertinggi<br />dicapai pada perlakuan pupuk KCl dosis 350 kg/ha, masing-masing adalah<br />86,88 cm, 272,51 g/tanaman, dan 27,46 g/tanaman. Peningkatan bobot<br />kering batang+daun dan bobot segar rimpang berkorelasi positif dengan<br />meningkatnya pemupukan KCl sampai dosis 350 kg/ha, membentuk<br />persamaan linier (r = 0,610 tn dan 0,643 tn ) dengan tingkat kepercayaan<br />masing-masing P = 0,987** dan 0,99**. Kadar serat rimpang meningkat<br />membentuk persamaan kuadratik (R 2 = 0,792*) dengan peningkatan<br />pemupukan KCl sampai dosis 350 kg/ha, dengan tingkat kepercayaan P =<br />0,997**. Serapan hara N, P dan K berkorelasi positif dengan peningkatan<br />pemupukan KCl sampai dosis 350 kg/ha. Serapan N membentuk<br />persamaan linier (r = 0,541 tn ) dengan tingkat kepercayaan P = 0,977**,<br />serapan P membentuk persamaan kuadratik (R 2 = 0,798*) dengan tingkat<br />kepercayaan P = 0,992**, dan serapan K membentuk persamaan kuadratik<br />(R 2 = 0,643 tn ) dengan tingkat kepercayaan P = 0,947**.<br />Kata kunci : Zingiber officinale Rocs., pupuk KCl, pertumbuhan, mutu,<br />hasil jahe muda<br /><br />ABSTRACT<br />Potassium is the nutrient most absorbed by ginger compared to N<br />and P nutrients. Crop productivity will decline if it lacks of K nutrient,<br />because K has an important function in the photosynthesis of process,<br />enzyme activity, metabolisms of carbohydrates and proteins, and it also<br />functions as an ion transport. A study, conducted at Sukamulya<br />Experimental Station from January to May 2010, aimed at determining the<br />effect of KCl fertilizer application on growth, yield, nutrient uptake, and<br />quality of young ginger rhizomes. Treatments were arranged in a<br />randomized block design with four replicates. The treatments consisted of<br />eight KCl fertilizer dosages, namely: 0, 50, 100, 150, 200, 250, 300, and<br />350 kg/ha. Planting space used was 50 x 60 cm, with plants population of<br />100/plot. Five plants per treatment unit were sampled at the age of 4<br />months after planting. Variables observed were plant height, number of<br />tillers, rhizome fresh weight, dry weights of rhizomes and plants, contents<br />of essential oil, starch, fiber, and N, P, and K nutrients. The results showed<br />that plant height, rhizome fresh weight, stems + leaf dry weight, and<br />rhizome dry weight increased significantly in line with the increase in KCl<br />fertilizer dosages. The best results of plant height, rhizome fresh weight,<br />and dry weight of stem + leaf were achieved at the highest dosage of KCl<br />fertilizer (350 kg/ha). The measures were 86.88 cm, 272.51 g/plant, and<br />27.46 g/plant, respectively. Increase in dry weights of stem + leaf and<br />fresh rhizome were positively correlated with increasing fertilizer dosages<br />of KCl up to 350 kg/ha, forming a linear equation (r = 0.610 tn and r =<br />0.643 tn ) with P confidence levels of 0.987** and 0.99**, respectively.<br />Increase in fiber content of rhizomes formed a quadratic equation (R 2 =<br />0.792*) by increasing dosages of KCl fertilizer up to 350 kg/ha, with a P<br />confidence level of 0.997**. Uptakes of N, P, and K nutrients were<br />positively correlated with increases in KCl fertilizations up to 350 kg/ha.<br />Uptakes of N nutrient formed a linear equation (r = 0.541 tn ) with a P<br />confidence level of 0.977**, P uptakes formed a quadratic equation (R 2 =<br />0.798*) with a P confidence level of 0.992**, and uptakes of K also<br />formed a quadratic equation (R 2 = 0.643 tn ) with a P confidence level of<br />0.947**.<br />Key words: Zingiber officinale Rocs., KCl fertilizer, growth, quality,<br />young ginger rizhome

Perbanyakan tanaman teh dengan menggunakan setek satu daun saat ini merupakan cara yang umum untuk memenuhi kebutuhan bahan tanaman dalam jumlah yang banyak dengan waktu yang singkat. Salah satu syarat dalam perakitan klon teh unggul baru adalah kemudahan klon tersebut untuk diperbanyak secara vegetatif. Hal ini dikarenakan klon yang mudah diperbanyak secara vegetatif lebih disukai oleh para pekebun. Salah satu pengujian yang harus dilakukan dalam proses pemuliaan tanaman teh adalah uji perbanyakan vegetatif pada kandidat klon unggul baru. Penelitian ini bertujuan untuk mengetahui variabilitas kemampuan pertumbuhan dan beberapa komponen pertumbuhan benih setek dalam uji perbanyakan vegetatif. Penelitian dilaksanakan di Persemaian Pemuliaan Kebun Percobaan Pusat Penelitian Teh dan Kina Gambung. Percobaan menggunakan Rancangan Acak Kelompok (RAK) dengan 19 klon sebagai perlakuan yang diulang tiga kali, setiap perlakuan ditanam 52 benih setek. Hasil penelitian menunjukkan bahwa hampir seluruh variabilitas genetik pada karakter yang diamati tergolong dalam kategori luas, kecuali untuk karakter panjang akar, dan berat kering akar. Variabilitas fenotipik menunjukkan bahwa hampir seluruh karakter yang diamati tergolong dalam kategori luas, kecuali berat kering akar. Currently, propagation of tea plant using one leaf is a common way to fulfil the need of plant material in large quantity also short in time. One of requirements in assembling new superior tea clone is the easy of clone to be propagated vegetatively. Clone which is easy to propagate in vegetative way is apt more by the gardeners. One required test on tea plant breeding process is vegetative propagation test of new superior clone candidates. This research aimed to determine variability of growth ability and several growth components of cutting seed in vegetative propagation. The research was carried out in Breeding Nursery, Experimental Field of Tea and Cinchona Research Institute Gambung. The trial was set in Randomized Block Design (RBD) with 19 clones as the treatment which was repeated three times, each treatment consisted of 52 cutting seeds. The result showed that almost all genetic variability of characters observed were included to wide category, except for root length and root dry weight characters. Phenotypic variability showed that nearly all characters observed were comprised to wide category, except root dry weight.
