The relationships within the <em>Alpine-Dinaric</em> and cultivated populations of the genus <em>Iris</em>, <em>Pallidae</em> series, have been analysed. Seven morphological characteristics (stem length, length of the largest leaf, greatest width of the largest leaf, length of the smallest leaf, greatest width of the smallest leaf, the number of leaves and the number of flowers) and seven leaf anatomical (length and width of stomata, length and width of epidermal cells, number of stomata and epidermal cells per mm'- and length of styloids) have been used for this purpose. Relationships between populations were analysed by methods of multivariate statistics (Cluster, PCA and MST analyses). The results of Cluster and PCA analyses showed that, owing to leaf anatomical features, five main groups of the populations could be distinguished within the <em>Pallidae</em> series. Four of them belong to the species <em>L. pallida</em>, <em>L. cengialti</em>, <em>L. illyrica</em> and <em>I. pseudopallida</em>. The MST analyses showed that the fifth group contained mixed populations of <em>I. illyrica</em> and <em>I. pseudopallida</em>. The results point at the lack of taxonomic usefulness of the leaf anatomical features analysed and indicate that they caused successive geographical differentiation of the populations of the <em>Pallidae</em> series.

The relationships within the Alpine-Dinaric and cultivated populations of the genus <em>Iris</em>, Pallidae series, have been analysed by methods of multivariate statistics (Cluster, PCA and MST analyses). The bases for multivariate analyses were seven morphological characteristics (stem length, length of largest leaf, greatest width of the largest leaf, length of smallest leaf, greatest width of the smallest leaf, the number of leaves and the number of flowers) and relative chromosome length for 12 chromosome pairs. In spite of two similar looking isolated populations (Stara Baška and Konavle), the presence of four groups within the series was established, to which a species status can be ascribed: <em>I. pallida</em> Lam. separated as a horticultural species, /. <em>cengialti</em> Ambr. - endemic in Alpine region, /. <em>illyrica</em> Tomm. - endemic to the northern Adriatic Littoral and <em>I. pseudopallida</em> Trinajstić - endemic to the southern Adriatic Littoral. To differentiate the established groups, in PCA analysis the most significant features turned out to be: relative chromosome length of eleventh and tenth chromosome pairs, the length of the smallest leaf, relative chromosome length of the seventh chromosome pair and length of the stem.

The growth and flowering of ‘Rupert’ and ‘Ronina’ lachenalia (Lachenalia) in a greenhouse environment were manipulated by varying planting times and flurprimidol treatments. Bulbs were planted in November, December, January, and February. At each planting date, the following flurprimidol treatments were tested: soaking the bulbs before planting (15 and 30 mg·L−1) or a single foliar spray (15, 30, 45, and 60 mg·L−1). The results showed that foliar application of flurprimidol was ineffective in controlling inflorescence stem height and inflorescence length; only soaking bulbs of ‘Rupert’ in flurprimidol at the concentration of 30 mg·L−1 shortened the inflorescence stem height. Moreover, soaking bulbs in the concentration of 30 mg·L−1 may be recommended for potted lachenalia production, as shorter and wider leaves were obtained and every planted bulb emerged and flowered. The later the date of planting of the bulbs, the more quickly the plants began to flower. As planting time was delayed, inflorescence stem length and leaf length decreased, and the number of florets and leaf width increased. Soaking the bulbs in the retardant (30 mg·L−1) delayed the emergence of flowers for 5–6 days, but the retardant did not affect the number of leaves or the number of florets per inflorescence. Regardless of the factors applied, the two cultivars of lachenalia differed with respect to each of the analyzed traits.

<p>Vanda Orchid is one of the most popular ornamental plants. Orchids have slow growth. One way to overcome this weakness is by using gamma-ray irradiation. This research aimed to study the morphological characters of various radiation doses resulting from the crossing of the Vanda Orchid. This study was carried out by observing the characters of vegetative growth for each plant on 0 Gy, 10 Gy, 20 Gy, 30 Gy, 40 Gy, and 50 Gy doses of gamma irradiation treatments. The observed variables were the increase in plant height, leaf length, root length, number of roots, number of leaves, leaf width, and leaf color. The results showed that the dose of gamma-ray irradiation were able to increase plant height. 10 Gy and 20 Gy, gamma-ray irradiation doses, resulted in discolored yellowing of orchid leaves. The discoloration of orchid leaves to light green occurs at irradiation doses of 30 Gy, 40 Gy, and 50 Gy. The morphological characteristics of <em>Vanda</em> sp. hybrid results gamma irradiation are high at dose 10-40 Gy.</p><p> </p><p>Keywords:<strong> </strong>characteristics; morphological; orchid.</p>

The aim of the study was to determine the effect of pH and soil chemical composition on morphological traits of common tansy (<i>Tanacetum vulgare</i> L.). A two-year study was conducted based on observations, measurements and analyses of material collected from 24 stands in the following regions: Równina Włocławska (Włocławek Plain), Wyżyna Lubelska (Lublin Upland), Padół Zamojski (Zamość Depression), Działy Grabowieckie (Grabowiec Divide) Płaskowyż Suchedniowski (Suchedniów Plateau), Wysoczyzna Siedlecka (Siedlce High Plain) and Niecka Połaniecka (Połaniec Basin). Morphological traits of tansy shoots were determined: number of plants per clump, stem length, number of leaves per plant, total leaf length, petiole length, number of branches from the main stem, number of flower heads per corymb and flower head diameter. A soil analysis was performed determining the content of magnesium, potassium and phosphorus available for plants. The soil pH was also determined. The collected results indicate significant differentiation of the investigated samples, both in terms of morphological traits of the shoots and the chemical composition of the soils. A negative correlation was found between soil pH and number of leaves per shoot as well as number of branches per corymb. A positive correlation was noted between soil pH and total leaf length as well as between magnesium content and number of flower heads per corymb. The increased content of available phosphorus in the soil was associated with petiole shortening. A growth trend in the tansy shoot length was observed at larger amounts of available magnesium in the soil. On soils with low nutrient availability and a low pH, a reduced population density of the species in question was observed.

Italian zucchini is a very important crop due to its short cycle, high productivity and great market acceptance. The objective of this study was to evaluate the emergence and growth of Italian zucchini plants in substrates enriched with sewage sludge. The study was conducted in a greenhouse using Italian zucchini seeds purchased at a local commerce. The substrates were composed of dystrophic Yellow Red Latosol; sand and sewage sludge in the proportions of 0; 40; 80; 120 and 240 t ha-1, in a randomized block design. Each experimental plot was composed of twenty replicates. The following variables were analyzed: emergence, emergence velocity index, first leaf length, stem length, number of leaves, fresh and dry aerial plant part, volume and root dry mass. It was verified that the post-seminal growth of Italian zucchini is viable in maximum concentration of up to 398.56 t ha-1 of sewage sludge.


Cold mitigation mechanism at seedling stage is a primary requirement during Boro season as seedlings are raised during months of November and December. This study was conducted at the Sylhet Agricultural University's Agricultural and Biosystem Engineering lab in Sylhet during the 2018-19 academic year. The focus of this study is to mitigate the biotic and abiotic effect on germination and mat-type seedling growing during the Boro season. A two-factor design with three replications was used in the experiment. As abiotic stress control factors, six treatments were taken under two different thicknesses (0.04 mm and 0.08 mm) of white polythene sheds that covered day time only (12 hours) and day and night time (24 hours). Along with that two fungicides (Atavo and Autostin) and MoP fertilizer were used to control biotic stress on young seedlings raised in a plastic tray. Agronomical characteristics were measured in two intervals (after 15 and 30 days). The combined effect of 0.08 mm thick polythene shed and MoP treatment showed the highest value for seedling height (167.3 mm), a number of leaves (4), leaf length (99.8 mm), stem length (73.5 mm), and seedling density (18/cm2). Fungal infection was found lowest in 0.08 mm polythene covered day and night time. Seedling raised plastic trays are much more effective than the conventional way in terms of germination and quality. So, 0.08 mm thick white polythene was recommended as a covering mechanism and MoP as a treating mechanism for seedlings rising in cold weather of the Sylhet region.

AbstractPhenotypic variation and association between morphologic traits and geographic characteristics (latitude, longitude and elevation) were investigated for fifteen wild birdsfoot trefoil (Lotus corniculatus L.) populations collected from diverse natural stands in Slovakia. Considerable variation between populations was observed for morphological characteristics. According to principal component analysis, the attributes that appeared to be the major sources of diversity between these populations were growth habit, number of internodes, stem length, stem thickness, number of stems per plant and leaf length. The populations were classified into five morphologic cluster groups, corresponding to collecting sites with similar geographic characteristics. This study showed that most populations from locations with lower elevation tended to produce semi-prostrate plants with high number of long stems and with later flowering. The number of stems, number of internodes and stem length increased as the population collecting-site location moved west and south. The results may be useful for planning more effective collection and utilization of several wild populations.
