In order to estimate the correlation between pollen viability, germination and the morphological traits, 15 Saintpaulia genotypes were analysed. Pollen viability was obtained by staining with potassium iodide (25%) and germination was estimated using solid nutrient medium (15% sucrose, 85% humidity, 22 °C temperature). Several morphological traits such as number of flowers, diameter of leaves rosette, number of leaves, length and width of leaves and petiole length were evaluated to determine growth indices. The results obtained indicated that ‘Hot Pink Bell’ genotype achieved the highest number of flowers and the largest diameter of leaves rosette. Genotypes ‘Tomahawks’ and S. grotei recorded the highest number of leaves. Higher width of leaves values was obtained in ‘Aloha Orchid’, while genotype ‘Park Avenue Blue’ was noted for a high length of leaves. Positive correlations were recorded among viability and germination in S. jonantha, S. rupicola and S. grotei. Significant positive correlation was registered between pollen viability and the number of flowers, but also between germination and the number of flowers per plant. The results indicated a possible correlation between viability, germination capacity and the morphological traits in most genotypes studied.

Garlic (Allium sativum L.) a clonally propagated bulbous crop, is of high medicinal value owing to its sulphur-containing compounds. Although asexually propagated, garlic depicts wide genetic diversity in agro-morphological traits and biochemical composition. A study was conducted to dissect the extent of genetic divergence among 625 Indian garlic genotypes considering 21 agro-morphological traits. Pooled analysis exhibited significant variation among accessions for various morphological traits. Ward’s clustering method clustered germplasm collection into three distinct groups. Clustering pattern did not correspond with geographical origin of accessions. Strong and positive correlation of marketable yield with plant weight with leaves (r = 0.83), plant weight without leaves (r = 0.84), average bulb weight (r = 0.50), plant height (r = 0.58), pseudostem length (r = 0.59), number of leaves (r = 0.54) and weight of fifty cloves (r = 0.49) was recorded. These traits will be useful for direct selection in crops like garlic. Principal Component analysis minimised 21 components up to 12 vectors which measured nearly 90% variation. Conservation of such vital and diverse garlic genotype is prerequisite to assure successful selection breeding programme.

AbstractRosa x odorata (sect. Chinenses, Rosaceae) is an important species distributed only in Yunnan Province, China. There is an abundance of wild variation within the species. Using 22 germplasm resources collected from the wild, as well as R. chinensis var. spontanea, R. chinensis ‘Old Blush’ and R. lucidissima, this study involved morphological variation analysis, inter-trait correlation analysis, principal component analysis and clustering analysis based on 16 morphological traits. This study identified a high degree of morphological diversity in R. x odorata germplasm resources and the variation coefficients had a distribution range from 18.00 to 184.04%. The flower colour had the highest degree of variation, while leaflet length/width had the lowest degree of variation. Inter-trait correlation analysis revealed that there was an extremely significant positive correlation between leaflet length and leaflet width. There was also a significant positive correlation between the number of petals and duration of blooming, and the L* and a* values of flower colour were significantly negatively correlated. Principal component analysis screened five principal components with the highest cumulative contribution rate (81.679%) to population variance. Among the 16 morphological traits, style length, sepal width, flower diameter, flower colour, leaflet length and leaflet width were important indices that influenced the morphology of R. x odorata. This study offers guidance for the further development and utilization of R. x odorata germplasm resources.

Abstract Anthemis L. is a genus of aromatic flowering plants in the family Asteraceae and is native to Iran. In this research, 62 accessions of four chamomile species including Anthemis tinctoria, A. triumfetti, A. haussknechtii and A. pseudocotula were evaluated for morphological traits. Four experiments were conducted using a randomized complete block design with three replications at the Research Institute of Forest and Rangeland, Tehran, Iran in 2011. Data were collected for the morphological traits for all of the species and essential oil content for A. triumfetti and A. pseudocotula. The results showed that plant height was positively correlated with canopy area for all of the species except A. triumfetti (p < 0.01). There were positive correlations between flower number with plant height and canopy area in both A. tinctoria and A. haussknechtii (p < 0.01). Fresh and dry weight were positively correlated with canopy area and plant height in all of the species (p < 0.01), except A. tinctoria for canopy area and A. triumfetti for plant height. GDD had a positive correlation with canopy area for A. triumfetti (p < 0.05). There was a positive correlation between essential oil yield and plant height, fresh and dry weight in A. triumfetti and A. pseudocotula (p < 0.05). Using cluster analysis (Ward method), the accessions of A. triumfetti, A. tinctoria, A. haussknechtii and A. pseudocotula were grouped into 3, 2, 4 and 2 clusters, respectively. The results of cluster analysis separated the accession based on shoot yield, morphological traits and maturity. In some items, the accessions within each cluster were coordinated with their geographical provenance.

Fifteen strawberry germplasm collected from local and exotic sources were evaluated for different qualitative and quantitative characters. The germplasm showed variation for majority of the studied traits. Plant height during peak harvest ranged from 14.67 to 25.00 cm and FA 007 exhibited the tallest plants. The maximum number of leaves plant-1 was produced by FA 006 (46.67). The maximum number of runners plant-1 was obtained in FA 003 (68.67) followed by FA 004 (63.00), while the highest number of crown plant-1 was found in FA 007 (15.33) followed by FA 006 (14.67). Days to flowering varied from 48.33 to 102.30 among the germplasm and FA 008 required minimum (48.33) days for flowering. The germplasm FA 004 produced the highest number of flower trusses (35.50 plant-1) while it was the lowest in FA 010 (5.00 plant-1). The number of flowers plant-1 was found maximum in FA 003 (168.00 plant-1) and minimum in FA 010 (40.00 plant-1). Among the germplasm pollen viability varied significantly and maximum viable pollen was recorded in FA 010 (84 %), while it was lowest in FA 004 (12.00 %). The highest per cent fruit set was recorded in BARI Strawberry-1 (86 %) while, FA 013 (39 %) showed the lowest. Among the germplasm the highest yield plant-1 was recorded from FA 005 (737.70 g) followed by FA 006 (702.30 g) and was significantly higher than others while the lowest yield plant-1 was recorded from FA 013 (52.00 g), FA 014 (69.00 g), FA 009 (81.33 g) and FA 010 (121.30 g).

Vegetative parameters of eight M3 (third mutant generation) lines of sesame were evaluated under rain fed condition. The seeds of the lines were sown alongside their respective controls using a randomized complete block design. The eight lines were generated from three parental stocks: NCRIBEN-04E (V1), NCRIBEN-01M (V2) and NCRIBEN-03L (V3). The three parental stocks were exposed to different doses of gamma irradiation from cobalt-60 source. 04E-550-G2-3 had the highest plant height (57.40) at the 6th week which was significantly different (P<0.05) from the three checks. 03L-450-G2-2 had the highest petiole length (12.45cm) which was significantly different (P<0.05) from the checks except check three (12.25cm) which was not significantly different (P>0.05). 03L-450-G1-2 had the highest number of leaves (91) and consequently highest number of branches (5.60). Although the number of leaves were significantly different (P<0.05) from Check three (54.60), there was no significant difference (P>0.05) between the number of branches and check three (5.40). The results obtained for vegetative parameters of M3 lines of sesame suggests that some of the genotypes could be used as potential parents for future breeding programmes aimed at improving sesame lines.

The Relationship

In this paper, we analyze reliability, correlations, regression of employee obligations, compare employee regression, job satisfaction regression, and hierarchical regression analysis. As techniques for comparison of entrepreneurs and employees are significant for analysis of positive correlations between the determinants, we used 36 independent samples and 210 individuals. The findings reveal that: (1) The results of the research confirmed the existence of a statistically significant positive correlation between the determinants of job satisfaction and organizational commitment on one hand, and the work of entrepreneurs, on the other; (2) The results of the survey compare the relationship between entrepreneurs and employee job satisfaction and organizational commitment, adding a significant increase in the importance of the construct; (3) Entrepreneurship has a relative correlation in relation to job satisfaction, and organizational commitment, and thus increases the scope of tasks and efficiency of entrepreneurs; (4) Entrepreneurs show dominance over employee satisfaction and organizational commitment, when they predict the success of a group or organization and organizational civic behavior. We recommend that future researches examine the relationship among entrepreneurs and their relationship with employees, as well as job satisfaction and organizational commitment, in order to potentially compare them.

The effects of flurprimidol at the concentration of 7.5 i 15 mg×dm<sup>-3</sup> on the growth and flowering of <i>Pelargonium hortorum</i> 'Omega' were examined in the years 2003 and 2004. Pelargonium plants were sprayed either once or twice; 2 weeks after planting rooted seedlings - first, and next - 2 weeks later. At the beginning, the plants were grown in a greenhouse, and then in a foil tunnel. Flurprimidol at the concentration of 15 mg×dm<sup>-3</sup> increased the number of leaves and intensified their colour, but reduced the plant height and diameter, shortened peduncles lowering their decorative value. 7.5 mg×dm<sup>-3</sup> of the retardant had weaker effects on <i>Pelargonium</i> morphological traits, but resulted in more abundant flowering, compact and proportional conformation and high decorative value.

Abstract The paper mainly described the haematological values of a fresh water catfish Hetropneustes fossilis (Bloch.) in relation to its length and weight which are the prime basic factor of the differences in blood parameters of any living creature including fishes. The hematological parameters showed significant differences with increase in length and weight of the fishes. Differential leucocytes count did not showed any significant differences except macrophages and differential erythrocytes count showed significant differences only in macrocytes. All three groups (Length and weight) of fishes showed significant positive correlations for total erythrocytes count, hemoglobin, mean corpuscular hemoglobin and erythrocyte sedimentation rate while negative correlation was noted for mean corpuscular hemoglobin; mean cell volume. Among differential leukocytes count only neutrophil showed positive correlation, while other parameters did not show any significant correlation. In differential erythrocyte count only microcytes showed significant positive correlation.

The purpose of the research was to study the correlates of self-esteem, negative attention-seeking dependency, and passive-approval-seeking dependency in missionary boarding school and nonboarding school students. Self-esteem was positively correlated with perceived approval of others, parental and houseparental acceptance, and identification with parents. Negative attention-seeking dependency for males was correlated positively with paternal psychological control, while for females negative attention-seeking dependency was negatively correlated with paternal acceptance and identification with father. For females there were significant positive correlations between passive approval-seeking dependency and the variables of father acceptance, father psychological control, and identification with mother. Consensual religious orientation was negatively correlated with self-esteem, and committed religiosity was negatively correlated with negative attention-seeking dependency. There were no significant differences between the specific groups of early, late, and nonboarders on any of the relevant variables, although, for those who boarded, there was a significant positive correlation between number of years boarding and self-esteem.
