Perakitan varietas baru anggrek dari Phaleonopsis memerlukan tetua dengan sifat tertentu yang disesuaikan dengan permintaan pasar. Keberhasilan perakitan varietas baru ditentukan oleh hubungan kekerabatan antar anggrek yang digunakan sebagai tetua sehingga diperlukan karakterisasi. Karakterisasi morfologi anggrek hybrid juga diperlukan untuk menentukan dan membedakan penampakan morfologi antar anggrek. Tujuan penelitian yaitu untuk menentukan keragaman morfologi anggrek Phaleonopsis spesies dan hybrid berdasarkan nilai Indeks Shanon dan menentukan hubungan kekerabatan berdasarkan nilai similaritasnya. Penelitian dilakukan di tiga kebun anggrek yang ada di Yogyakarta yaitu Kebun Anggrek Balelawang, Titi Orchids, dan Kebun Anggrek Mas Jogja. Penelitian ini menggunakan metode observasional deskriptif yaitu pengamatan langsung di lapangan terhadap lima belas anggrek Phaleonopsis berdasarkan Panduan Karakterisasi Anggrek dari Balai Tanaman Hias. Hasil pengamatan morfologi tanaman dan bentuk bunga anggrek diubah menjadi data biner. Penentuan keragaman diketahui melalui perhitungan Indeks Shanon dan hubungan kekerabatanya diketahui menggunakan software Numerical Taxonomy and Multivariate Analysis System (NTYSYS) Spc 21. Berdasarkan karakter morfologinya menunjukkan nilai Indeks Shanon sebesar 2,70 yang diklasifikasikan dalam keragaman sedang. Hubungan kekerabatan Phaleonopsis spesies dan hybrid membentuk dua kelompok dengan nilai similiaritasnya 0,48.

Phenetic Analysis and Distribution of Claoxylon in the Lesser Sunda Islands. Floribunda 6(5): 167–174.  — The genus Claoxylon A.Juss. in the Lesser Sunda Islands (LSI) was reviewed. Eleven species were recognized in Lesser Sunda Islands. Records of C. capillipes and C. fulvescens were extended to the Bali Island. Based on distribution of Claoxylon in LSI, Bali has the highest number of species (7 species), while Wetar shows the least number of species (only 1 species). A phenetic analysis was using Numerical Taxonomy and Multivariate Analysis System (NTSYS-pc) version 2.11a and distribution mapping using Quantum GIS version 2.4. Based on 14 morphological characters grouped Claoxylon species in LSI into three groups. All Claoxylon in LSI belong to section Indica and Affinia.

This study examined the nature and amount of feedback that more successful and less successful high school varsity volleyball coaches gave to their starting and nonstarting volleyball players. Two of the four coaches studied were considered more successful and two were considered less successful, based on previous regular season win-loss percentages. Players of all the coaches (N=41) were also used as subjects and identified as having either a starting or nonstarting role on the team. All subjects were observed on three occasions for 30 minutes per observation during regular season practice. The Cole Descriptive Analysis System (Cole-DAS) was used to observe coach augmented feedback as it was given to individual players in response to skilled performance. A 2 × 2 multivariate analysis of variance was used to describe the effects of (a) success of the coach, (b) role of the player, and (c) both success of the coach and role of the player on the dependent variables of coach augmented feedback. Results indicated that successful coaches varied considerably from less successful coaches in the types of feedback given to their players. Starting players were also found to receive significantly more audio, audiovisual, and immediate terminal feedback than nonstarting players.

The amount of DNA varies widely in 20 shrubby Oxalis species analyzed, ranging from 1.76 pg in O. alstonii to 33.00 pg in O. dispar. This wide variation in DNA content coincided with a wide variation in chromosome size and shape. Numerical taxonomy methods showed that this variation in chromosome size and shape in shrubby Oxalis is mainly due to extra DNA. It was also possible to arrange the 20 species examined in six different groups on the basis of karyotypic similarities.Key words: Oxalis, DNA content, chromosome evolution, multivariate analysis.

Abstract Numerical taxonomic study of the genus Crotalaria L. in Nigeria was conducted to identify and differentiate some of the species of the genus Crotalaria using numerical taxonomy based on quantitative and qualitative characters. Field work was conducted, where different species were collected and analyzed using multivariate analysis. The results showed that all the collected species are distinct at Euclidian distance of 0.41 in the cluster analysis with Cophenetic correlation (r)=0.964. The ordination analysis based on the results of the PCA, separated the specimens into 7 groups corresponding to the result of cluster analysis. The first two components of the PCA account for 81.5%. The length of petiole, width of leaflet and length of fruit contributed more to showing delimitation among the species.

Two species of Ornithogalum subg. Heliocharmos are present in North Africa: O. algeriense and O. kochii. These are often confused with O. umbellatum from Europe. Several populations covering the spread of variation of these species were studied biometrically using macromorphological characters. Multivariate analysis results suggest that O. kochii is close to the diploid cytotype of O. umbellatum. The diploid cytotypes are closer to the popyploid series of O. umbellatum than to O. algeriense. These results are discussed in relation to biogeography and evolution. Key words: Angiosperms, Hyacinthaceae, Ornithogalum, subg. Heliocharmos, numerical taxonomy, systematic, biogeography, flora of Marocco, flora of France. [Journal translation]

The objective was to distinguish between cultivars and evaluate genetic relatedness of poinsettia (Euphorbia pulcherrima) using two methods of DNA fingerprinting—DNA Amplification Fingerprinting (DAF) and Arbitrary Signatures from Amplification Profiles (ASAP). Eleven red poinsettia cultivars were studied, including `Celebrate 2', `Darlyne', `Freedom Red', `Lilo', `Nutcracker Red', `Peterstar Red', `Petoy', `Red Sails', `Supjibi', `V-14 Glory', and `V-17 Angelika'. Amplification was with 10 octamer primers. Gels were visually scored for presence or absence of bands. The 10 primers generated 336 bands. The average number of bands (≈1000 bp) per primer was 34 ranging from 19 to 43. Thirty-one percent of bands were polymorphic and distinguished between each cultivar. The number of unique profiles varied from two to nine. Genetic relationships were evaluated by SAHN cluster analysis based on the distance estimator of Jaccard using the NTSYS-pc program (Numerical taxonomy and multivariate analysis system, version 1.8). The resulting dendrogram closely agreed with known pedigree data. ASAP analysis was used to further assess cultivar identification of two cultivars that were genetically and morphologically similar. Markers were found that separated `Nutcracker Red' and `Peterstar Red'. ASAP analysis separated cultivars within the Freedom series that DAF failed to distinguish. Two cultivars in the Freedom series, `Jingle Bells' and `Marble', were characterized from other cultivars in the series with ASAP.

To investigate the effects of garment hue, garment value, and garment style on college recruiters' assessments of employment potential a 2 × 2 × 2 experimental design was used. Experimental conditions were based on recommendations from a commercial color analysis system to evaluate also the role of personal color analysis. Photographs were attached to questionnaires which contained seven employment potential statements. Factor analysis generated two employment potential factors, Leadership and Compatibility. Multivariate analysis of factor scores yielded a significant 2-way interaction for hue × value. Univariate F tests gave a significant effect for Compatibility. Generally, value appeared to have a greater influence on assessments of employment than did hue. There were no significant effects associated with style of garment. In addition, the results did not fully support the commercial color recommendations.

The objective was to distinguish between series of cultivars of Pelargonium xhortorum (zonal geranium), Pelargonium hybrids (seed geranium), and Pelargonium peltatum (ivy leaf geranium) using DNA amplification fingerprinting (DAF) demonstrating the utility of DAF for patent protection to prevent infringement of inventor's rights. Leaf tissue of 10 plants of each cultivar of seedling geranium was bulked for DNA extraction, and cutting and ivy geranium cultivars were bulks of five plants of each cultivar. Isolated DNA from different cultivars of a series were bulked together in their respective series. Seedling geranium series included Dynamo, Glamour, Multibloom, Orbit, Pinto, and Ringo 2000. Cutting geranium series included Designer and Showcase. Ivy geraniums were from the Guillou group. Amplification was with one of two octamer primers, followed by reamplifying with one of four different mini hairpin primers. Gels were visually scored for presence or absence of bands. The four primers generated 336 bands. The average number of bands (_1000 bp) per primer was 40. Twenty percent of bands were polymorphic and distinguished between each series of cultivars. Genetic relationships were evaluated by SAHN cluster analysis based on the distance estimator of Dice using the NTSYS-pc program (Numerical taxonomy and multivariate analysis system, version 1.8). Series were grouped according to species. Seedling geraniums were in one large group, the two cutting geraniums were grouped together and the ivy leaf geraniums were a separate branch.
