<p><strong>Colour alternation and et/tylene changes during ripening tobacco leaves cultivar Madura and its effect to the quality of slice Madura tobacco</strong></p><p>The colour change and elhylene production in the leaves of Madura tobacco (Nicotiana tabacum) during ripening was studied at "Labora¬ torium Biokimia Pusat Antar Universitas Pangan dan Gizi Universitas Gadjahmada Yogyakata" and "Laboratorium Inti dan Atom Jurusan I'isika, FMIPA Universitas Gadjahmada Yogyakata". The change of colour was measured with Chrommameter CR-200. while the production of ethylcne, ACC (1-aminocyclopropanc-l-carboxylic acid) and MACC (malonyl-ACC) were measured with Photoaccuslic Spectroscopy, from the sample of 100 kg tobacco leaves cv. Jepon grown from April to September 1995 in Plakpak, Pcgantenan, Pamekasan, East Java. The experiment was designed as a completely randomized design in three replicates. The leaves samples were taken randomly from the mature middle leaves Results showed that endogenous ethylcne production al the irst day al a level of 169 ppb. was able to initiate ripening. Conversion percentage of ACC to ethylcne for 8 days ripening increased from 7.7 up lo 61.4 %. F tests least signiicantly different (1%). showed that yellow intensity signiicantly increased on the second day. This indicated thai ripening process was stated on the second day. On the other hand green intensity significantly decreased at the ifth day, thus no chlorophyl degradation. Brightness was signiicantly observed on Ihe third day of ripening, meaning that ripening stated on the third day. Based on the three criteria, the best ripening period was from the third lo the ilth day. This implies that the farmers will have three day periods of ripening which can be arranged to overcome the shotage of man power for slicing the leaves.</p>

Abstrak.  Terong belanda merupakan buah berasa asam yang khas, namun memiliki warna yang kurang menarik. Disisi lain buah  bit mempunyai warna yang menarik, karena pada buah bit terkandung pigmen betalain yang dapat menghasilkan warna merah dan ungu. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh konsentrasi CMC dan penambahan buah terong belanda dan bit terhadap mutu organoleptik sorbet. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan faktor perbandingan buah terong belanda dan bit (P1 = 1:1, P2 = 2:1 dan P3 = 3:1) dan konsentrasi CMC ( C1 = 0%, C2 = 0,25%,  C3 = 0,50 % dan C4 = 75 %) dengan total  24 satuan percobaan. Hasil analisis menunjukkan penambahan proporsi terong belanda cenderung meningkatkan nilai organoleptik aroma dan rasa, sedangkan peningkatan konsentrasi CMC cenderung meningkatkan nilai organoleptik warna, rasa dan tekstur. Sorbet dengan perlakuan terbaik berdasarkan analisis keseluruhan diperoleh dengan menggunakan buah terong belanda:bit(2:1) dengan respon uji hedonik untuk warna 4,53 (agak suka), aroma 4,23 (netral), rasa 4,40 (agak suka) dan tekstur 4,63 (agak suka). Abstract. Terong belanda is a sour-taste typical fruit, but it has a less attractive color. On the other hand, beetroot has an interesting color because it contains betalain pigment producing red and purple colors. The purpose of this study was to determine the effect of CMC concentration and the addition of terong belanda and beetroot on the organoleptic quality of sorbet. This study used a Completely Randomized Design (CRD) with the ratio of terong belanda and beetroot factor (P1 = 1:1, P2 = 2:1 and P3 = 3:1) and CMC concentration factor (C1 = 0%, C2 = 0.25 %, C3 = 0.50% and C4 = 75%) with two replicates creating a total of 24 experimental units. The results showed that the addition of terong belanda tended to increase the proportion of aroma and taste organoleptic values, while the increase in the concentration of CMC tended to improve the color, taste and texture organoleptic values. The best Sorbet was obtained using the ratio of terong belanda and beetroot (2:1) having the following hedonic characteristics: 4.53 (a bit like) color, 4.23 (neutral) aroma, 4.40 (rather like) flavor and 4.63 (a bit like) texture.

The present study was conducted to polyploidy possibility induction of two Iranian endemic mint (Mentha mozaffarianii) ecotypes. For this purpose, three experiments were done. The first experiment was factorial, based on completely randomized design with three factors and three replications that rhizomes were used for treatment. The first factor including different colchicine concentrations (0, 0.025, 0.05, 0.1 and 0.2% that 0 as control). The second factor including two Mentha ecotypes (Ecotype A: Kamarej region and Ecotype B: Pirmohlat region) and the third factors consist of two soaking time (6 h and 12 h). In second experiment, apical meristem was treated. The factorial experiment based on randomized completely design with two factors and five replications. The factors including different colchicine concentrations (0, 0.035, 0.07, 0.15, 0.3 and 0.7%) and two ecotypes. In the third experiment, colchicine as combined with irrigation was applied. For this purpose, a factorial experiment in randomized complete design with two factors (colchicine concentrations: 0, 0.025, 0.012, 0.006% and two mint ecotypes) and three replications was conducted. At the end of all experiments, survival rate and tetraploidy percentage (by morphological change, stomata traits, flow cytometry and chromosome counts) were measured. The results showed that different treatment had significant effects on survival percent on all experiments and increasing of colchicine concentration caused decreasing plants survival. On the other hand, tetraploidy changes only in the first experiments were observed. Only in 0.025% colchicine treatment with 6 h soaking time on ecotype A, 12.66% tetraploidy was identified. Totally, it is seems that Mentha mozaffarianiihardly response to colchicine for tetraploidy induction.
