Data Grouping

Vegetative development of 12-month-old Smooth Cayenne plants was observed as affected by planting position, slip pruning and slip size. Data taken included plant height, spread, leaf number and "D"-leaf weight, length, width and thickness. Results showed that vegetative development was not affected by planting in a vertical or inclined position. Plant height, number of green leaves, and "D" leaf weight were negatively affected when slip leaves were pruned although reduction in leaf area is supposed to affect fruit yield. There was no difference among the three pruning treatments. Size of slips showed highly significant differences in all variables observed with the exception of leaf width. Vegatative development was proportional to slip size even though climate and soil conditions were very favorable to growth and development. Growth was vigorous and succulent. Correlation coefficients between all variables studied were highy significant. Plant weight, slip weight, stem weight and stem diameter showed consistent correlation values. Mean comparisons present data grouping on two levels. Slip weight under 200 grams did not show good development.

Maturity Groups

In this paper we studied the variability and correlation of cabbage traits in different maturity groups. The study included early spring cabbages (planted in early spring, harvested in early summer) and autumn cabbages (planted in mid-summer, harvested in late autumn). Using coefficients of variation and correlation coefficients, we analyzed 17 cabbage traits in 35 commercially grown cultivars, F1 hybrids, and experimental F1 hybrids. The traits were analyzed separately for each maturity group. In the early cabbages, the coefficients of variation ranged from 4.8 to 44.2%. The calculated correlation coefficients differed between the two maturity groups. The early cabbages had 26 significant positive correlations. The positive correlations calculated among different traits of early cabbages defined this group fully and made it distinct from the late-maturing genotypes. Plant height and rosette diameter in the early genotypes were highly positively correlated with rosette weight, whole plant weight, head weight, usable portion of head, head height, and head diameter. Plant height and rosette diameter participate in the formation of active photosynthetic area in early cabbages. Rosette width in these genotypes provides a greater influx of light and heat, which results in greater head weight. Also, in early cabbages that have greater plant height, the leaf rosette will not lie on the cold surface of the ground in the spring. The activity of the cabbage plant is thus more focused towards the formation of larger head weight. Head volume in the late genotypes was highly positively correlated with rosette diameter, whole plant weight, head weight, usable portion of head, inner stem length, and head height. In late cabbages plant activity is directed towards the formation of head volume due to the longer duration of the growth period, larger leaves, and differences in climatic conditions.

Quantifying bone loss is important to decide the best treatment for patients with recurrent anterior glenohumeral instability. Currently, there is no standard method available to make a precise evaluation of the Hill–Sachs lesion and predict its engagement before the surgical procedure. This literature review was performed in order to identify existing published imaging methods quantifying humeral head bone loss in Hill–Sachs lesions. Searches were undertaken in Scopus and PubMed databases from January 2008 until February 2018. The search terms were “Hill-Sachs” and “measurement” for the initial search and “Hill–Sachs bone loss” for the second, to be present in the keywords, abstracts and title. All articles that presented a method for quantifying measurement of Hill–Sachs lesions were analysed. Several methods are currently available to evaluate Hill–Sachs lesions. The length, width and depth measurements on CT scans show strong inter and intra-observer correlation coefficients. Three-dimensional CT is helpful for evaluation of bony injuries; however, there were no significant differences between 3D CT and 3D MRI measurements. The on-track off-track method using MRI allows a simultaneous evaluation of the Hill–Sachs and glenoid bone loss and also predicts the engaging lesions with good accuracy.

Passionflower is a member of Passifloraceae family, it can be used as medicinal and ornamental plants in addition to its consumption as fruit in the world. Guava (Psidium guajava L.) fruits, which has a rich nutrient content, are consumed both fresh and processed. Passionfruit and guava plants, which can only be cultivated in temperate southern coasts in our country, have gained commercial importance because of the fruits' export potential, high medical importance and nutrient. This study was carried out to determine the effects of some bioactivator applications on the criteria of sapling growth and development of passionflower and guava plants. The experiment was conducted between 2018-2019 under greenhouse conditions. Saplings obtained from seed germination in Akdeniz University Faculty of Agriculture Research and Experiment Area were used as plant material. 3 different commercial preparations called Messenger, Crop-set and ISR-2000 were used as bioactivators. Plant height (cm), stem diameter (mm) and number of leaves (number / plant) were measured weekly, in order to determine the effect of the applications on the growth and development of saplings. At the end of the study, it was determined that the highest average plant height (10.17 cm), stem diameter (13.53 mm) were obtained in ISR-2000 application. The highest average plant height (11.93 cm), stem diameter (16.44 mm) and number of leaves (9.07 units / plant) were obtained from Messenger application in guava plant. When the results obtained are evaluated, it is recommended that ISR-2000 bioactivator can be applied in passionflower sapling cultivation and Messenger bioactivator can be applied for guava sapling cultivation.

Sage and mountain sage belong to Lamiaceae family which have commercial importance from medicinal and aromatic plants in Turkey. The aim of this study was to evaluate the effects of different doses of selenium in salinity conditions on the morphological characteristics of sage (Salvia officinalis L.) and mountain tea (Sideritis sp.). Four different doses of selenium (5, 10, 20, 40 mg/l) were applied in without salinity (0) and salinity (250 mM NaCl/l) medium. The experiment was carried out in the split plot design with three replications in the climate chamber room of the department of field crops. When the examined properties were evaluated; plant height changed between 15.56-23.85 cm, number of branches 10.50-12.78 number/plant, number of leaves 52.78-92.00 number/plant, fresh leaf weight 2.48-7.51 g/plant, dry leaf weight 0.48-3.32 g/plant, fresh root weight 1.52-7.16 g/plant, dry root weight 0.19-1.24 g/plant, root length 26.18-36.07 cm, fresh shoot weight of 1.13-7.15 g/plant and dry shoot weight 0.13-0.38 g/plant. In mountain tea, the properties were determined for plant height as 3.26-5.93 cm, for number of branches as 2.50-6.33 number/plant, for number of leaves as 28.22-91.14 number/plant, for fresh and dry leaf weights as 2.42-11,03 and 0.45-1.91 g/plant, for fresh and dry root weights as 0.71-3.97 and 0.18-0.74 g/plant, for root length as 14.78-33.26 cm, for fresh and dry shoot weights as 0.29-2.28 and 0.12-0.41 g/plant were determined. As a result of this study, 5 mg/l selenium application in salinity conditions in both plants has reached high values in terms of fresh leaf weights. In addition to this, it was found that selenium applications in salinity conditions had positive effects on dry leaf weight in sage and fresh root and fresh shoot weights in mountain tea. As a result of correlation analysis, positive correlations were found between dry leaf weight and other characteristics especially in mountain tea in terms of traits examined in both plants.

The central-north of Brazil is a region with strong presence of concrectionary soil, whose supposed disadvantages from the agronomic point of view, do not prevent their use in agriculture. However, more in-depth information about the behavior of crops of agricultural interest cultivated in this type of soil is few. Due to the observation of agricultural stands in this type of soil, it was hypothesized that plinthite ironstones concretions negatively interfere in the development of crops of agro-economic interest. The objective was to verify the growth and development of soybean cultivated in soil with the presence and absence of plinthite ironstones. Concretionary Petric Plinthosol were collected in the 0-0,20 m layer and part of the soil was sieved so that concretions larger than 3.10 mm in diameter were removed, thus leaving two treatments, soil with and without plinthite ironstones. Morphological evaluations were performed during their phenological phase. Soybean grown in soil without ironstones showed higher growth at 32 and 48 DAE and more leaflets when compared to soy crop grown in soil with ironstones. As for dry matter, soybean grown in soil without ironstones showed more values for aerial, root and total mass as well for aerial root rate when compared to soybean grown in soil with ironstones. Plinthite ironstones interfere with the growth and/or vegetative development of soybeans. Soybean has less vegetative development when grown in soil with plinthite ironstone concretions.

In field experiments performed in two localities (Smolice, Wrocław) 18 xenic hybrids of winter rye, two testers and standard cultivar Dańkowskie Złote, were analysed. The objects of detailed evaluations were 11 traits. For six of them arithmetic means (x), standard deviations (S), coefficients of variation (cv), coefficients of genetic diversity (h<sup>2</sup>), correlation coefficients were calculated. Moreover, analyses of variance were carried out and the effects of general (GCA) and specific (SCA) combining ability were estimated. The existence of quantitative xenia in hybrids was confirmed. It was shown that xenic hybrids, in respect to most of the analysed traits, were insignificantly inferior to the testers and the standard cultivar. However, the decrease of plant height has shown to be significant and a tendency to higher yield was observed.

This study aimed to evaluate different substrates to produce yellow passion fruit seedlings. For this purpose, an experiment was carried out in a greenhouse, from April to June 2016. A completely randomized design with five replications, in a 6 x 5 factorial scheme was used. The first factor was the alternative substrates (poultry, cattle and equine manure, sugarcane and coconut bagasse, and Organomais compost). The second factor was the replacement levels to the commercial substrate of Plantmax® (100:0, 75:25, 50:50, 25:75, 0:100). The seedling evaluation was carried out 42 days after sowing. The following variables were analyzed: length, width, and the number of leaves; plant height and shoot dry matter. A significant effect (P0.05) for the interaction between the factors was verified. The addition of 60% cattle manure and Organomais to the commercial substrate Plantmax® promoted greater length, width, and the number of leaves, plant height, and shoot dry matter accumulation in the yellow passion fruit seedlings.

In modern conditions, the need for cultivation of grain sorghum in regions with insufficient moisture is determined by its high yield and grain quality. For practical breeding, with the objective of assessing linkages 19 morphological and physiological traits model of the population including 15 varieties and 2 promising lines of grain sorghum that is created in the Russian Research and Design Technological Institute of Sorghum and Maize. The biochemical composition of the grain of the objects of research is presented graphically. A different degree of variation in the characteristics of grain sorghum was revealed: very strong (V> 40,0%) - productive bushiness, number of grains from 1 panicle; strong (20,0% <V <40,0%) - the width of the panicle, the extension of the panicle leg, the thickness of the upper internode, the area of the flag leaf, the area of the fourth on top of the leaf, the mass of the grain from 1 panicle; weak (V <10,0%) - the height of the plants after 30 days, the height of the plants during maturation. The group with an average degree of variation (10.0% <V <20.0%) includes all other signs measured in the experiment. Factor analysis was used to optimize, interpret the calculated matrix of correlation coefficients. In the analysis of the correlation coefficient matrix, hypothetical factors with a contribution of more than 5% to the accumulated variance are calculated. The first hypothetical factor is determined by the high effects of morphophysiological features. The second factor is largely due to the contribution of plant height 30 days after germination and the extension of the panicle legs. Plant height at maturity, weight of 1000 grains make the greatest contribution to the third factor. The width of the panicle makes the greatest contribution to the accumulated dispersion of the fourth factor. The fifth factor is determined by the effects of plant height at the beginning and end of vegetation, as well as the total contribution of all studied features.
