Abstract

Growth pattern and nutrient uptake of Echinacea purpureaEchinacea purpurea or purple cone flower, belongs lo Aslcraceac family which grown naturally in Noth America. The plant known as is Ihe number one Immune herbs in the world, since it has a greal potential lor improving and developing leukocyte cell activity. Recently, Echinacea has been evalualcd/tcsled as adjuvant in cancer therapy, AIDS and chronic exhaustion. Echinacea purpurea is more potential for immunity improvement lhan those of other herbal medicine. Therefore, the study on its growlh rale, growth pattern, and nutrient uptake in a new tropical environmental condition is very important in order lo suppot its cultivation technology, lo identify the growth pattern, growlh rale, nutrient uptake, and simplisia quality. A ield trial had been conducted in Cipanas at 1 100 m above sea level (asl) in 1999-2000. Plot size was 4x3 m, and plant spacing was 50 x 40 cm. Ten samples was taken from each growth stage of the plants. The growth stages were (I) vegetative I (VI) at I month alter planting (map), (2) vegetative 2 (V2) al 1 .5 map, (3) generative I (Gl) at 2 0 map, (4) generative 2 (G2) at 2.5 map. (5) generative 3 (G3) at 3.0 map. and (6) generative 4 (G4) al 3.5 map. The results of the research showed thai growth rate, nutrient uptake of N, P. K. Mg. and S linearly increased in line with Ihe increase of plan! ages The highest dry weight accumulation was found on aerial part of plant (slem I leal), and the lowest was occurred on root pat. The amount of dry weight accumulation was 75.72 g/plnul. and nutrient uptake oIN, P. K.Ca, Mg, and S. respective!) was 1529.1. 1 40.01. 1943.25, 654.59. 358.66. and 88.57 mg/plant.

Abstract

Morphological and physiological characteristics of Vinca at di fferent water stress levelsVinca (Vinca rosea L.) is one of the important medicinal crops as the sources of raw materials for traditional medicines. Its alkaloid is believed can reduce the risk of cancer, blood tension and diabetes diseases. Recently, vinca is only grown as ornamental plant in the garden, therefore, its cultivation methods is limited, especially its water stress tolerance, lite purpose of this experiment was to study the effect of water stess on the morphological and physiological characteristics of vinca. A pot experiment was conducted in the plastics house of the Research Institute for Spice and Medicinal Crops from November 1997 to March 1998. Factorial experiment consisted two factors and three replications was arranged in a randomized block design. Ihe irst factor consisted of two vinca varieties, those wee white flowers (WFV) and red flowers of vinca (RFV). While 4 different levels of water stress i.e., (I) 100% ield capacity (FC), (2) 80% FC, (3) 60% FC, and (4) 40% FC were used as the second factor. Parameters used for evaluating the effect of teatment consisted of morphological characteristics such as (I) plant height, (2) number of primary branches, (3) number of leaves, (4) leaf area (5) dry weight of stem, (6) dry weight of leaf, (7) dry weight of flowers and (8) dry weight of roots, and physiological characteristics observed including: (I) percentages of opened stomata and (2) free proline content of leaf. Results showed that interaction between varieties and water stress did not significantly affect the morphological nor physiological characteristics. Varieties significantly affected the morphological characteristics (except plant height), however they did not signiicantly affect physiological characteristics. Water stress significantly affected the morphological (except dry weight of roots) and free proline contents. Under 80% FC, vinca produced the highest growth and dry weight of plant however, the plant growth and dry weight wee inhibited under 60 and 40% FC. Under 40% FC, percentages of opened stomata deceased signiicantly. Moeover, proline content in the leaves signiicantly increased by water stess treatments.

Abstract

ABSTRAKPengembangan   serai   wangi  memerlukan   ketersediaan   benih bermutu. Sampai saat ini, informasi standar mutu benih serai wangi masih terbatas. Penelitian ini bertujuan untuk mengetahui viabilitas benih serai wangi dengan jumlah ruas dan panjang batang yang berbeda sebagai dasar penyusunan Standar Nasional Indonesia (SNI). Penelitian dilakukan di rumah kaca Balai Penelitian Tanaman Rempah dan Obat (Balittro) dari Mei sampai Juni 2013 dengan menggunakan benih serai wangi klon G 2. Percobaan disusun secara faktorial dengan tiga faktor dan diulang empat kali dalam Rancangan Acak Kelompok (RAK). Faktor pertama adalah jumlah ruas stolon: (1) satu dan (2) dua. Faktor kedua adalah ukuran panjang batang semu: (1)15, (2) 20, dan (3) 25 cm. Faktor ketiga adalah periode penyimpanan: (1) 0, (2) 3, (3) 6, (4) 9, dan (5) 12 hari. Parameter yang diamati meliputi kadar air, daya tumbuh, serta bobot basah dan kering.  Hasil  penelitian  menunjukkan viabilitas  benih  serai  wangi dipengaruhi oleh jumlah ruas stolon dan panjang batang. Benih dengan dua ruas dan panjang batang 25 cm mempunyai viabilitas lebih baik dibandingkan satu ruas dan panjang 15 cm. Sampai 12 hari penyimpanan di suhu kamar, benih masih segar dengan daya tumbuh 83,75%.Kata kunci:  Cymbopogon  nardus  L.,  jumlah  ruas,  panjang  batang, penyimpanan, viabilitas ABSTRACTEffect of Internodes Number and Stems Length on Viability of Citronella Seeds (Cympobogon nardus L.) Development of citronella required the availability of good quality seed. Presently, standard information of citronella seed quality is not available. The research aims to study the viability of citronella seeds from different internodes number and stem length as the basic for preparing Indonesian National Standards. The experiment was conducted in the green house  of  the Indonesian Spice and Medicinal Crops Research Institute (ISMECRI), from May until June 2013, by using citronella clones G 2. Factorial experiment with three factors and four replications was arranged in a Randomized Completely Block Design (RCBD). The first factor was  internodes numbers: (1) one and (2) two. The second factor was stem length: (1) 15, (2) 20, and (3) 25 cm. The third factor was storage periods: (1) 0, (2) 3, (3) 6, (4) 9, and (5) 12 days. Parameters observed included seeds moisture content, seeds germination, fresh, and dry weight. The results of experiment indicated that viability of citronella seeds was affected by stolon internodes number and stem length. Seeds with two internodes and stem length 25 cm has better viability than with one of internode and 15 cm   of stem   length.   Up to 12 days storage at room temperature, the seeds were still fresh with the germination 83.75%.Keywords:  Cymbopogon nardus  L.,  internodes number,  stem length, storage, viability
