Saffron is an aromatic herb appreciated for its olfactory qualities, but also for its medicinal contributions, having multiple pharmaceutical properties. The cultivation of saffron in Romania is rather little known, the scientific data obtained being of interest for farmers who want to start such a culture. In this paper two populations of saffron were studied, the bulbs being of the same origin and age, grown in two different localities in western Romania: Izvin and Cicir. Regarding the quality characteristics, the two cultures belong to quality categories 1 and 2, and analyses were determined on moisture, colouring power (crocin), aromatic power (safranal) and bitterness power (picrocrocin). From a quantitative point of view, the variability of morphological characters, the manifestation of morphological characters, the coefficients of corallance on characters such as: number of bulbs, total diameter of bulbs, diameter of dominant bulb, length of leaflet, leaf length, leaf width, number of leaves dominant bulb, petal length, petal width, petal number, stamen length, stigma length were determined.

The ornamentally important genus Adonis L. (Ranunculaceae) consists of about 30 species. In Iran, 8 species are recognized. The new classification system recognizes two subgenera, six sections, and six series for Adonis. The species differentiation within the genus is controversial due to morphological overlaps in different species and extensive morphological variation. Therefore, the aims of present study were: 1- Species delimitation within the Sect. Adonis based on morphological and molecular evidences and, 2- Studying the species relationship based on molecular phylogeny. Multivariate analyses of morphological and molecular (ITS and ISSR) data differentiated the Adonis species. PCA biplot analysis of morphological characters revealed morphological characters such as leaf arrangement; leaf length, flower diameter, petal length and width, calyx length, and pedicel length are of taxonomic implication in Adonis. Bayesian tree of ITS sequences revealed that the sect. Adonis is differentiated from the sect. Adonanthe. Based on ITS data, A. microcarpa showed close affinity to A. scrobiculata, while A. aestivalis, A. icrocarpa and A.dentata were close to each other.

The excessive use of agrochemicals in agriculture has been causing irreversible environmental impacts, from this point of view, organic farming appears as an economically viable alternative to minimize these impacts. So, the objective of this work was to evaluate the effect of different types organic fertilizers in the development and production of coriander harvested at different epochs. The experiment was conducted during the period from August to October 2016, in an area of the experimental farm of University of International Integration of Afro-Brazilian Lusophony. The experimental design was a randomized complete block design, in a 5 × 4 factorial scheme, consisting of five organic fertilizers and four harvesting epochs (28, 35, 42 and 49 days after planting-DAP) and five blocks. The variables stem diameter, plant height, root size, number of leaves, leaf length and productivity were evaluated. All the analyzed variables responded significantly by the F test, either for the qualitative factor, fertilizer sources, or the quantitative, epochs of evaluation. Regarding the cultivation epochs, when the first evaluation period (28 DAP) was compared with the last (49 DAP), it was verified that the variables presented linear responses over time, with increases of 34.4% for height , 29.5% for stem diameter, 37.07% for root length and 64.44% for production. In relation to the fertilizer sources, in general, the cattle manure provided a greater growth and production of the coriander plants, being therefore the most suitable for the cultivation.

Dendrobium is the most commonly grown tropical orchid species in India and Kerala. They are highly specific about their nutrient requirement. The use of bio-inoculants in crop production of ornamentals has opened up a new possibility of using them for improving the growth and yield of orchids. Hence the objective of study was to evaluate the response of Dendrobium cv. Yellow Splash to different kinds of bio-inoculants viz., AMF, Azospirillum and a microbial consortia PGPR Mix – 1 developed from KAU, along with 50, 100 and 150 ppm of benzyladenine. The experiment consisted of ten different treatments involving bio-inoculants and benzyladenine. Plant height and number of leaves were maximum in the plants inoculated with AMF along with 100 ppm benzyladenine. Treatment comprising of Azospirillum and 100 ppm benzyladenine was superior in terms of other morphological parameters like leaf breadth, leaf area and plant spread. Maximum leaf length and highest number of shoots were observed in plants inoculated with Azospirillumand 150 ppm benzyladenine. Considering the floral parameters, both quantitative and qualitative attributes were found to be superior in the treatment consisting of AMF along with 150 ppm benzyladenine. Highest root length was observed under the treatment AMF along with 100 ppm benzyladenine while number of roots and root volume were maximum in the plants inoculated with Azospirillum and 150 ppm benzyladenine. Plants inoculated with AMF and 100 ppm benzyladenine had highest chlorophyll content while highest stomatal frequency was observed under the treatment Azospirillum and 100 ppm BA. From the study it could be concluded that inoculation of Dendrobium orchids with bio-inoculants like AMF and Azospirillum can significantly improve the morphological characters of the plants which in turn influence the production of quality spikes.

A diallel cross of four cigar and one pipe tobacco was analysed for the following characters: (1) height before topping (2) height after topping (3) number of leaves (4) leaf width (5) leaf length (6) leaf angle and (7) days from transplanting to flower. The experiment was performed over three years with four replications. Analysis was done for general combining ability and specific combining ability. General combining ability was in all cases greater than specific combining ability, although there were some specific combining ability effects. The line Pennbel 69 showed very high positive general combining abilities for all characters while the line Petit Havane showed negative general combining abilities for these characters. Commercial production of F1 hybrids would not seem to be of any advantage for any of these characters with these parental lines.

Western Ghats provide asylum to several endemic plants. Exacum tetragonum Roxb. is one of the important endemic herbs inhabiting the hilly tracts and midlands of Kerala, the state of India located towards the south-western side of the Western Ghats. The plant is used for treating fever, stomach disorders, gout, diabetics, and eye diseases. It is also found associated with antioxidant, anti-inflammatory, anti-helminthic and anti-hyperglycemic activities. Correlation and association of characters of this important medicinal plant was analyzed based on the observations on thirteen salient morphological characters recorded from twenty three populations of the species distributed across Malappuram, Thrissur, Kozhikode and Palakkad Districts of Kerala State of India. All the characters studied such as plant height, number of leaves, number of flowers, number of inflorescences, leaf length, leaf breadth, peduncle length, pedicel length, internodal length, leaf area, mean stem girth, number of branches and fresh weight of plants showed statistically significant variations between the populations. Number of flowers showed significant positive correlation with the maximum number of characters (ten characters) whereas number of leaves showed significant positive correlation with the minimum number of characters (two characters). By factor analysis, two factors could be extracted and fresh weight of plant was found to be the lead character. Significant variability with regard to morphological characters indicates the strong genetic base of the plant species in the field. However, drastic changes in its habitat for various reasons can certainly cause severe threats to its continued existence and hence appropriate actions to conserve the natural habitats of this species are vital.

A field experiment was conducted at the research field of Sher-e- Bangla Agricultural University, Dhaka during the period from December 1, 2016 to January 11, 2017 to investigate the effect of gibberellic acid (GA3) on vegetative growth, morphological attributes and foliage (leaf) yield of coriander (Coriandrum sativum L.). The experimental treatments consisted of eight different doses of GA3 viz., 0 (distilled water spray), 5, 10, 15, 20, 25, 30 and 35 ppm. The variety Rosina (Pahuja Co., India) was used as planting material and different doses of GA3 were applied on the plants at 25 and 30 days after sowing. The experiment was laid out in Randomized Complete Block Design with three replications. GA3 had significant effect on vegetative growth, morphology, foliage yield and yield contributing characters of coriander. Plant height, number of leaves plant-1, leaf length, plant spread and single plant weight were found maximum from the application of GA3 at 20 ppm, which was closely followed by 25 ppm GA3. Application of GA3 at 20 ppm produced the highest weight of foliage m-2. A strong positive correlation of foliage yield was observed with plant height, number of leaves plant-1, leaf length, plant spread, single plant weight and weight of foliage m-2. Application of GA3 at 20 ppm gave maximum foliage yield (9.34 t ha-1) which was followed by GA3 at 15 ppm (8.46 t ha-1) and 25 ppm (8.06 t ha-1), and the minimum foliage yield was recorded from control (distilled water spray) (4.90 t ha-1). Application of GA3 at 20 ppm increased foliage yield over control by 47.54 %. A quadratic relationship between applied GA3 concentration and foliage yield was found; the regression equation was y = 4.87 + 0.375x – 0.009x2 from which it came up to be optimum dose of GA3 as 20.83 ppm.Res.

Performance of ‘Bilati Dhonia’ (Eryngium foetidum L.) grown under the shades of different tree species, namely guava, jackfruit, mango, jujube, and farmers’ practice (grown under artificial shade) was evaluated at the Agricultural Research Station, Raikhali, Rangainati Hill District during two consecutive years of 2004-05 and 2005-06. The results revealed that plant height, leaf length, number of leaves per plant and fresh weight per plant were significantly higher under the canopies of various trees and farmers’ practice than those grown under direct sun light. Different growth characters were better under the shades of jackfruit and guava trees than those of other species. Periods to first and 50% flowering under tree species were longer than that under direct sunlight. The highest fresh yield (mean of two years) of ‘Bilati Dhonia’ was found in the farmers’ practice (27.58 t/ha), which was similar to those under guava (27.31 t/ha) and jackfruit trees (27.51 t/ha).

ABSTRACT The banana crop stands out as an activity of great social and economic importance in Brazil, which occupies the fifth place in world production. Synthetic seed production is becoming promising for a micropropagation and in vitro conservation. The aim of the study was to analyze the conversion and growth of ‘Prata-anã’ banana’s microshoots clone Gorutuba from synthetic seed in MS medium and vermiculite, different substrates and concentrations of BAP (6-benzylaminopurine) associated with ANA (acetic naphthalene acid) in the constitution of its capsule were tested. The microshoots were immersed in the sodium alginate matrix (3%) and dripped in a solution of CaCl2.2H2O (100 mM) for complexation and then in KNO3 solution (100 mM) to decomplex. The experimental design was completely randomized in a 2 x 5 factorial design (substrate x BAP concentrations), containing different substrates (MS culture medium and vermiculite) and BAP concentrations (2.22, 4.44, 6.66, 8.88 and 13.32 µmol L-1) associated with NAA (naphthalene acetic acid) 0.54 µmol L-1, totaling 10 treatments, with 4 replicates, and that each replicate containing 5 seeds. The evaluations of conversion, number of leaves, leaf length, leaf height, number of roots, root length and oxidation were performed at 30 and 60 days.The use of the MS medium provided better growth results in relation to vermiculite as substrate, in which the different BAP concentrations did not differ from each other. It was found that, in MS culture medium, BAP concentrations above 8.88 µmol L-1 in the capsule composition are not indicated for microshoots growth.
