The Impact

Idesia polycarpa, Igiri tree, is a deciduous ornamental tree with 10 to 20 cm (4 to 8 in) long panicles of yellow-green flowers in spring and summer, maturing to ornamental orange-red berries in fall and winter. There are limited vegetative propagation protocols established for I. polycarpa. The objective of this study was to evaluate the effectiveness of different timing and auxin concentration combinations on rooting success of shoot tip cuttings. In 2009, there were nine collection dates of softwood cuttings during the summer and three indole-3-butyric acid (K-IBA) concentrations of 0, 5,000, and 10,000 mg·L−1 (PPM). Increasing the K-IBA rate to 10,000 mg·L−1 resulted in higher rooting percentages for most collection dates, though rooting percentage did not exceed 32% for any given treatment combination. The date cuttings were taken did not affect rooting percentage. Cuttings that did not receive K-IBA did not root. In 2010, the impact of cutting harvest date (softwood in June and semi-hardwood in September) and the effect of K-IBA rate (0, 10,000, and 20,000 mg·L−1) on rooting was determined. There was no statistical difference between the two higher concentrations, but both improved rooting versus the nontreated control, which did not root. Softwood cuttings showed a higher rooting percentage and greater root length compared to semi-hardwood cuttings.

Marcotting is a method of vegetative propagation which still finds its relevance in the present day forest management and routine practice to produce viable seedlings for the regeneration of Ternstroemia cameroonensis. There is dearth of information regarding the propagation of T. cameroonensis by marcotting. Hence effects of phytohormone application (Indole-3-acetc acid, Indole-3-butyric acid) and alternative sources (coconut water) on the propagation of T. cameroonensis by marcotting were investigated in the Lebialem Highlands. Mortality rates, number of roots, root length as well as marcotts position in the crown was evaluated. The propagation trials were carried under natural environmental conditions. Marcotts had an overall survival percentage of 35.41%. Those established at the middle of the crown had the highest survival percentage (15.27%) followed by those at the lower (11.80 %). Also marcotts established on branches with larger diameter (4-6 cm) and shorter length (50 cm) had the highest survival percentage (20.13 and 19.44 respectively). Again marcotts treated with IBA and CW had the best performance compared to other pre-treatments. According to the result, T. cameroonensis can be amenable through marcotts.

In a study of stock plant etiolation and stem banding, stem cuttings of upright European hornbeam (Carpinus betulus L. `Fastigiata') were taken at 2-week intervals over 4 months following budbreak and rooted under intermittent mist for 30 days. Percent rooting and root counts declined with increasing cutting age. Stock plant etiolation and stem banding increased percent rooting and root counts throughout the study, with the combination of both treatments yielding the best rooting. In nontreated stems, > 75% rooting was achieved only within 4 weeks of budbreak. Etiolation and stem banding resulted in rooting ≥ 75% up to 3 months after budbreak. In two shading studies, stock plants were grown in a glass greenhouse under 0%, 50%, 75%, or 95% shade, or initially etiolated (100% shade) for 1.5 days. Cuttings were taken after 2.5 and 60 days and treated with IBA concentrations ranging from 0 to 4.9 mm before rooting under intermittent mist for 30 days. Percent rooting increased proportionally to the degree of shading, with a maximum response at 95% shade. Cuttings taken at 60 days were less responsive to etiolation and shading than those harvested at 25 days. Auxin concentration interacted with shading to yield, at 95% shade and 3.7 mm IBA, the highest rooting percentage and the greatest root counts and lengths. Light exclusion by etiolation, stem banding, or shading can extend the cutting propagation season by increasing rooting responses and increasing the sensitivity of stem cuttings to exogenously applied auxin. Chemical name used: 1H-indole-3-butyric acid (IBA).

Rooting Response

The influence of time of year, cutting position, and auxin concentration, formulation, and solvent on rooting of stem cuttings of shantung maple (Acer truncatum Bunge) was investigated in seven experiments. Softwood, semi-hardwood, second-flush softwood, and hardwood stem-tip cuttings were compared. Semi-hardwood cuttings [15 cm (6 in) in length] rooted best (55%). Auxin treatments [indole-3-butyric acid (IBA) or the potassium (K) salt of IBA (K-IBA)] ranged from 0 to 15,000 ppm (0 to 1.5%). Generally, rooting percentage decreased as auxin concentration increased. Cutting position (terminal or subterminal), auxin formulation (liquid or powder), and auxin solvent [water or ethanol:water (1:1 v/v)] did not affect percent rooting. Mean root number and mean root length were unaffected by all treatments. Results suggest shantung maple roots best from semi-hardwood cuttings treated with auxin at concentrations of 0 or 2,500 ppm (0.25%).

Significant Factors

Cupressus cashmeriana is an ornamental evergreen conifer with little published information on vegetative propagation. Two experiments were conducted to determine the effects of cutting type and auxin concentration and form on adventitious rooting. Experiment 1 evaluated three cutting treatments (softwood, hardwood, and mallet) and four auxin treatments consisting of 0, 2500, 5000, and 10000 ppm potassium salt of indole-3-butyric acid (K-IBA). Experiment 2 evaluated the same cutting types as experiment 1 and auxin treatments consisted of 5000 ppm K-IBA, 5000 ppm naphthalene acetic acid (NAA), 2500 ppm K-IBA in combination with 2500 ppm NAA and zero auxin applied. In both experiments, rooting of softwood and hardwood cuttings was significantly higher than mallet cuttings. Treatment of cuttings with different rates and types of auxin lead to inconclusive results, which indicate auxin may not be beneficial for rooting of C. cashmeriana. This research suggests that the age of plant material is one of the most significant factors for successful rooting C. cashmeriana.

Superior Clones

Even though the Lavandula species may be propagated by seeds, it should not be the preferred propagation method because it causes a great lack of uniformity. On the other hand, asexually propagated lavender crops would provide more homogeneous crops, and clones from high quality plant material would increase the odds for obtaining a higher quality essential oil. However, problems such as poor rooting and restrict market availability for superior clones have been a problem in vegetative propagation of the Lavandula species. The objective of this work was to define which type and size of cutting is more adequate for cutting propagation of L. dentata, a very productive Lavandula species. Cuttings with 5, 8, 10 or 13 cm and from the apical or basal parts of stems cut from L. dentata stock plants were placed in Plantmax HT® filled polystyrene foam trays and kept under intermittent mist system for two months. Averages of root number, length of the longest root, fresh and dry root weight, and percentage of rooting were evaluated. Apical cuttings combined 97.9% rooting with an average of 13.2 roots per cutting and basal cuttings 93.7% rooting with 2.98 roots per cutting. Apical cuttings with at least 10 cm in length were considered the most adequate for cutting propagation of L. dentata.

Attempted to evaluate and compare the impact on quality of life of occupational and non-occupational ACD and to identify the most frequently involved allergens. A quality of life questionnaire was applied. We noted moderate impact on the quality of life of both groups, without a statistical difference. Our study corroborates previous general data on the prevalence of nickel sulphate and paraphenylenediamine as the most common allergens. Potassium bichromate was shown to be one of the main occupational allergens and thimerosal as the main non-occupational allergen in our sample.

The Impact

This study investigates the impact of emigration on the political behavior of citizens in Egypt. In particular, it argues that emigrants’ family members are more likely to vote for Salafi parties for several reasons, including the transfer of religious remittances by Egyptian emigrants to the Gulf and the influence of transnational Salafi networks. In order to test our argument, we conducted an original public opinion survey with around 1100 individuals between January 12, 2012 and January 25, 2012, just after the Egyptian parliamentary election. We find that individuals with family members who had emigrated to the Gulf voted heavily for Islamist parties, particularly the Freedom and Justice Party and the Nour Party. Further analysis shows that there is no statistical difference between individuals with and without emigrant family members in voting for the Muslim Brotherhood, while the Nour’s popularity among voters with emigrant family members is substantial and statistically significant. In particular, we find that the strongest support for the Nour came from individuals whose family members had immigrated to Saudi Arabia, whereas those whose family members had immigrated to other countries, including other Gulf countries, do not differ significantly from non-emigrant family members in their party preferences.

Warm Season Grasses

Perennial warm-season grasses including switchgrass (Panicum virgatum L.), big bluestem (Andropogon geradii Vitman), and Indiangrass (Sorghastrum nutans L.) have drawn interest as bioenergy feedstocks due to their high yielding capacity with minimal amounts of inputs under a wide range of environments, and their capability to produce multiple environmental benefits. Nitrogen (N) fertility and harvest timing are considered as critical management practices when optimizing biomass yield and the feedstock quality of these grasses. The objective of this investigation was to quantify the impact of N fertilizer rate, N timing and harvest date on warm season biomass dry matter yield. Research was conducted in 2014 and 2015 on a total of four field-plot locations situated in central and west-central Missouri. Nitrogen fertilizer was applied using dry ammonium nitrate at the rates of 0, 34, 67, and 101 kg ha-1 at two application times, all N early spring and split N (early spring and following 1st harvest). Harvest treatments were as follows: 1) one cut in September; 2) one cut in November; 3) one cut in June and a second in September; and 4) one cut in June and a second in November. Treatments were arranged in a split-plot design with N rate as the main plot and harvest as the sub-plot in arandomized complete block design. Both N and harvest date and their interactions impacted biomass yield at all four locations. Delaying harvesting until late fall or killing frost increased yield. November harvest in combination with N rates grater than or equal to 67 kg ha-1 year-1 produced higher yields compared to the control and 34 kg ha-1N treatments and other harvest timing strategies. Although N was needed to optimize yield, partial factor 24 productivity (PFP) of applied N was flat when N applied was greater than 34 kg ha-1. Nitrogen fertilization at 67 kg ha-1 per growing season provided an opportunity to maintain a balance between both yield and efficiency of N inputs. Results of this research highlight the interactions of N fertilization and harvest management have when optimizing yield of warm-season grasses grown as bioenergy feedstocks. List of acronyms: N, Nitrogen; PFP, partial factor productivity.

The Impact

An experiment was laid out to study the impact of eCO2 (550ppm), eT (+3ºC) and their interaction (eCO2+eT) on rooting behaviour of cuttings of three grape varieties- Thompson Seedless, Bangalore Blue, and Dogridge in FATE and OTC facilities. Observations were recorded at 50 and 80 days after planting (DAP) and root growth data was recorded and analysed using WinRHIZO root scanner and its software. Analysis revealed that, among the selected grape varieties, Thompson Seedless cuttings has shown highest number of roots, root volume and dry biomass under eCO2 and eCO2+ eT conditions, while total root length and root length density were highest with Bangalore Blue. Under eT condition, Bangalore Blue showed highest number of roots, total root length and root length density, while root volume and dry biomass was highest with Thompson Seedless. The per se values of root parameters under all conditions and their response to eCO2 was lowest with Dogridge. Though eT condition reduced all the root parameters, their performance improved under eCO2+ eT indicating the presence of higher concentration of CO2 reduced the ill effects of high temperature. Overall, eCO2 and eCO2+eT conditions improved root parameters of grape varieties, while eT reduced them as compared to their performance under ambient condition and varietal variation is significant.
