The objective of this study was to determine the tolerance of daffodil (Narcissus poeticus L. c.v. “Ice Folies”) as a hyperaccumulator plant to nickel contaminated media. This research was carried out in a completely randomized plot experimental design with three replications in green house conditions. Four doses of nickel (control, 25 mg kg-1, 50 mg kg-1, 75 mg kg-1) were applied to each growing media having 500 g soil:sand mixture in  2:1 ratio. The distillate water was used in irrigation and Hoagland solution was applied for fertilization. At the end of the experiment, effects of nickel applications on leaf length, plant length, flower length (P<0.01) and flower diameter, stem diameter (P<0.05) were found significant, except leaf number and leaf length. The lowest first flowering time, full flowering time and first floret withering time were obtained in control and 75 mg kg-1 nickel application. The highest leaf length (341.60 mm), plant length (418.24 mm), flower length (70.74 mm) and stem diameter (7.63 mm) were obtained in 75 mg kg-1 nickel application. The highest flower diameter was found as 78.35 mm in 25 mg kg-1 nickel application. Generally, while the nickel doses increased flowering time, leaf length, plant length, flower length and flower diameter increased.

An experiment was carried out using eight double cross F1s (DCF1s) as lines and two testers to obtain sixteen Line ×Tester hybrids for the evaluation of major growth and flowering traits thereby to understand the breeding potentiality of the parental lines. The performance of growth and flowering traits of all twenty-six genotypes were evaluated in a randomized complete block design (RCBD) with three replications. The analysis of variance (ANOVA) showed all the genotypes were significantly different for all agro-morphological traits under study. The estimated general combining ability (GCA) effects showed that parent 5(P5), were superior for plant height, stem diameter, number of leaves, leaf length, days to flowering and attitude of floral axis followed by parent 2(P2) for leaf length, leaf width, days to flowering and attitude of floral axis and parent7 (P7) for number of flower, flower diameter, bud length and attitude for floral axis. Likewise; tester 1 found to be best combiner with significant GCA effect for almost all growth and flowering traits (except number of leaves). The plant height, leaf width, number of flower and attitude of floral axis showed prevailing additive gene action while stem diameter, number of leaves, leaf length, days to flowering, flower diameter and bud length indicated predominance of dominance gene action. We can conclude that parent P5, parent P2 and parent P7 can be used as good mother lines and the tester 1, as good donor for the seed production. SAARC J. Agri., 17(1): 175-187 (2019)

We investigated the effect of paclobutrazol as preplant bulb soaks on plant heightof Iris x hollandica cv. ‘Frans Hals’ and ‘Blue Magic’cultivars which were grownin pots. Bulbs of iris were soaked into gibberellin inhibitor paclobutrazol solutionat 0, 15, 30 ppm before planting. Effect of paclobutrazol on the flowering time,flower diameter and length, leaf length, plant height, flower life, and chlorophyllcontent of leaves were determined. The shortest plant height was obtained from the‘Blue Magic’ cultivar treated with 30 ppm paclobutrazol which gave plants with11.3 cm, 68% shorter than untreated control. ‘Frans Hals’ cultivar treated with 30ppm paclobutrazol was 20.9 cm and 50% shorter than control. In ‘Blue Magic’ and‘Frans Hals’cultivars the lower dose of 15 ppm paclobutrazol were also effectiveon height control with 11.8 and 21.5 cm plant height, respectively. This gibberellininhibitor also shortened the leaf length of iris cultivars. Paclobutrazol treatmentsresulted in higher chlorophyll content per unit area in the leaves. The highestchlorophyll content (57.00 CCI) was obtained from the ‘Blue Magic’ iris treatedwith 30 ppm paclobutrazol, while the control plants had 32.70 CCI chlorophyll intheir leaves. Chlorophyll content of ‘Frans Hals’ treated with 30 ppm paclobutrazolwere 52.87 CCI, while control plants of this cultivar were 28.80 CCI. Plantsapplied with paclobutrazol resulted with smaller flower diameter compared to thecontrol plants of both cultivars. The smallest flower diameter was obtained from 30ppm paclobutrazol treatment with 38.83 mm in ‘Blue Magic’ iris while the controlof this cultivar was 99.63 mm. The flower diameter of ‘Frans Hals’ cultivar treatedwith 30 ppm paclobutrazol was 109.1 mm, while the control one was 112 mm.

The aim of this research was to determine the optimum planting density for the production of high-quality cut flowers with desirable characteristics. 25 single-stem ornamental sunflower genotypes were planted at different densities and evaluated for flowering time, flower diameter, and stem circumference and length over a two-year production cycle. Three spacing patterns were used: 25 × 25 cm, 30 × 30 cm, and 70 × 30 cm, which led to the planting densities of 160 000, 90 000, and 60 000 plants/ha, respectively. The plant density had the most important effect on the stem circumference, flower diameter, and stem length (total variation 52, 60, and 58%, AMMI analysis) and a small effect on the flowering time (total variation 1%, AMMI analysis). Based on environment-focused scaling, all high-density environments could be suitable for the production of single-stem sunflower genotypes. The results demonstrated the adaptation of several sunflower genotypes G9, G11, G12, G21, and G22 as the most suitable based on the optimum flower diameter, stem circumference, and stem length. These results may lead to progress in growing ornamental sunflowers as a cut flower.

This study aimed to evaluate the growth characteristics of irrigated Vitória pineapple plants grown in semi-arid conditions and determine its developmental stages based on those characteristics. It was used a randomized block design with four replicates. The experimental treatments were: plant harvest at 270, 330, 390, 450, 510, 570, 690, 750, and 810 days after planting (DAP). The following variables were determined: plant height, stem diameter, D-leaf length, D-leaf fresh and dry mass, biomass production of plants and plant parts (organs), and vegetative biomass. Five phenological stages are proposed based on vegetative biomass production: < 20% biomass production (V1); 21-40% (V2); 41-60% (V3); 61-80% (V4); and > 80% (V5). The maximum growth rate for plant height, D-leaf length, and stem diameter was observed at the end of the phenological stage V1 (390-411 DAP), and at the end of stage V5 these plant traits had average values of 106, 82, and 7 cm, respectively. The maximum biomass accumulation rates were observed at stages V4 and V5, resulting in a final fruit yield and total fresh biomass of 72 t ha-1 and 326 t ha-1, respectively. Finally, we estimated that 80% of the accumulated biomass may remain in the field after fruit and slip harvest, and could be incorporated as plant residue into the soil.

Tetraploid landraces of wheat harbour genetic diversity that could be introgressed into modern bread wheat with the aid of marker-assisted selection to address the genetic diversity bottleneck in the breeding genepool. A novel bi-parental Triticum turgidum ssp. dicoccum Schrank mapping population was created from a cross between two landrace accessions differing for multiple physiological traits. The population was phenotyped for traits hypothesised to be proxies for characteristics associated with improved photosynthesis or drought tolerance, including flowering time, awn length, flag leaf length and width, and stomatal and trichome density. The mapping individuals and parents were genotyped with the 35K Wheat Breeders’ single nucleotide polymorphism (SNP) array. A genetic linkage map was constructed from 104 F4 individuals, consisting of 2066 SNPs with a total length of 3295 cM and an average spacing of 1.6 cM. Using the population, 10 quantitative trait loci (QTLs) for five traits were identified in two years of trials. Three consistent QTLs were identified over both trials for awn length, flowering time and flag leaf width, on chromosomes 4A, 7B and 5B, respectively. The awn length and flowering time QTLs correspond with the major loci Hd and Vrn-B3, respectively. The identified marker-trait associations could be developed for marker-assisted selection, to aid the introgression of diversity from a tetraploid source into modern wheat for potential physiological trait improvement.

The continuous destruction of our rainforest has threatened the existence of many useful and multipurpose plant species such as Tetrapleura tetraptera. To revert this situation, efforts must be made towards its sustainable use by encouraging reforestation which entails raising of seedlings for mass propagation of this crop. This study was aimed at comparing the effects of organic (chicken litter) and inorganic (NPK 15:15:15) fertilizers on seedling growth in four accessions of Tetrapleura tetraptera and hence determining fertilizer preference for this forest species. The Complete Randomized Design (CRD) was used in a factorial arrangement with four accessions and three fertilizer types in eight replicates. One month after transplanting, the fertilizers (organic and inorganic) were uniformly applied at the rate of 45 kg/hectare according to the experimental design. Data were collected monthly for a period of three months on plant height, stem diameter, leaf area, leaf length, member of branches, number of leaves, primary and secondary internode length per plant. Data on seedling emergence were also taken. Data collected were subjected to a two-way analysis of variance. Least significant difference (LSD) was used to separate significant means at p = 0.05. Result obtained revealed that the soil was rich in calcium, phosphorus and organic matter but low in nitrogen and potassium which were adequately complemented in mean days to seedling emergence in four accessions studied. Our findings also revealed that the organic (chicken litter) fertilizer did better (P<0.05) in all accessions than inorganic (NPK 15:15:15) fertilizer for all morphological traits studied. The performance of Cross River accession was outstanding as illustrated by the significant interaction obtained in most parameters. With chicken, litter fertilizer, Cross River accession produced the tallest plant (27.38 cm), largest leaf area (1.99 cm2), highest number of branches (20.13), highest number of leaves (66.75), longest stem diameter (0.93 cm), longest leaf length (1.94 cm), lowest primary (0.80) and lowest secondary (0.83) internode length. The use of organic fertilizers is therefore recommended for improved seedling growth of Tetrapleura tetraptera.
