Resumen

Due to film-mulched cultivation and poor irrigation practices, low oxygen stress could be often caused in root zone in greenhouse, and has negative effects on crops growth. In this study, a barrel experiment was conducted to probe the effects of root zone aeration on tomato (Lycopersicon esculentum Mill) leaves, root systems and biomass accumulation, using calcium peroxide (CaO2) as oxygen release agent. The results show that i) root zone aeration has little effect on the number of leaves and leave chlorophyll content, while reduces leaf areas of per leave and per plant, ii) root zone aeration could promote the growth and development of roots through increasing the volume, absorption area, specific surface area and total length of tomato roots and iii) root zone aeration raises the biomass of tomato plants, which mainly manifests in the increase of stems and leaves, especially in leaves.

Resumen

When <em>Xanthium</em> lamina width is plotted versus leaf length during the entire period of growth, a straight line is obtained representing an allometric relationship with a regression correlation coefficient of 0.9973 a lamina width to length ratio of 0.502 ± 0.01 and chordate morphology. On the other hand, gibberellic acid treated plants yield a correlation coefficient of 0.9871 a lamina width to length ratio of 0.372 ± 0.0074 and lanceolate leaves. The fraction of leaf width to leaf length is a measure of lamina width reduction. Gibberellic acid alters the mechanism which controls the balance between the leaf length and the leaf width.

Resumen

An experiment was conducted at the University of Agriculture, Sub-campus Burewala Vehari during spring 2018 to investigate the most effective growth media for the growth of kinnow Mandarin seedlings along with highest potential of root, shoots, branches and leaves growth. The growing media is crucial for better plant growth and development. Seeds of Kinnow Mandarin were sown in twelve (12) different composite media (made from different proportions of peat moss, coco coir, compost, baggase, and soil) in CRD with three repeats. Data regarding germination of kinnow seeds and seedling quality parameters (Fresh weight, dry weight, seedling length, root shoot ratio, dry matter contents) were recorded during the experiment. The results proved that the peat moss was the most efficient among all the other growing media for producing the maximum number of leaves, shoot length, root length and seedling length while, compost was found to be a most effective medium for maximum seed germination. The composition in 1:1 of baggase + peat moss was most prominent to produce leaves with larger surface areas. Therefore, peat moss is an effective growth media among other growing media for Kinnow production.

Resumen

Yellow-leafed cultivars usually do not grow as vigorous as their green-leafed counterparts, which affect their use in landscapes. To breed Forsythia cultivars with both yellow leaves and vigorous growth, crosses between F. ‘Courtaneur’ (♀) and Forsythia koreana ‘Suwon Gold’ (♂) were conducted, and 52 F1 hybrid progenies with different leaf colors (green, chartreuse, and yellow) were obtained. The progenies were categorized into three groups [Yellow Group (YG), Chartreuse Group (CG), and Green Group (GG)] based on leaf colors. The growth index (GI) and the number of branches and leaves of YG progenies were significantly lower at 2%, 35%, and 34% of GG progenies. As the leaves changed from green to chartreuse and to yellow, chlorophyll content, leaf thickness, and chlorophyll fluorescence parameters decreased and the chloroplast structures were disintegrated gradually, which influenced the leaf photosynthetic activity and led to weak growth. Compared with yellow-leafed progenies, the leaf chlorophyll content and leaf thickness of chartreuse-leafed progenies were significantly higher at 71% and 9%. The chloroplast structure of stroma lamella of chartreuse-leafed progenies was relatively intact. Carboxylation efficiency (CE), photochemical efficiency of PS II (Fv/Fm), and the number of branches and leaves of GG progenies were significantly higher than YG progenies; however, they have no significant difference with CG progenies. The results were promising for breeding new forsythia cultivars from moderate growth and chartreuse leaves.

Resumen

In this work, the effects of double, triple and quadruple combinations of gibberellic acid, kinetin, 24-epibrassinolide and polyamines (cadaverine, putrescine, spermidine, spermine) on the stomata movements in the leaves of barley seedlings grown under saline conditions were studied. In the control seedlings, the stomata number, stomata index and stomata length increased in the upper surfaces of leaves in comparison with their lower surfaces. In addition, the epidermis cell number in the leaves of control plants were fewer in the upper surface than that in the lower surface, but the stomata were statistically in the equal width in both surfaces. As for the applyings, they generally decreased stomata number, stomata index, stomata length and epidermis cell number, while they increased the stomata width in the upper and especially in the lower surface according to the control. The growth regulators used may have served to adaptation of barley seedlings to saline conditions by causing a decrease in most of the mentioned parameters.

Resumen

This article deals with using computer vision in the evaluation of the Lemna minor bioassay. According to the conventional method, the growth of Lemna minor mass is determined from the number of leaves grown. In this work, instead of counting individual leaves, we propose measuring the area occupied by the leaves using computer vision and compare the new approach with the conventional one. The bioassay is performed according to the ISO 20079 standard as a 168 h growth inhibition test; the aim of the experiment was to quantify the negative effects on the vegetative growth using two parameters—the number of leaves and the area occupied by the leaves. The method based on image processing was faster and also more precise since it enabled us to detect the negative effect of the tested substance on leave size, not only on their number. It can be concluded that the toxic effect has shown to be more significant when considering the leaves area rather than the number of leaves. Moreover, mistakes caused by human factor during leaves counting are eliminated using the computer vision based method.

Resumen

ABSTRACT: Formation of organ shape is an intriguing yet largely unanswered question in developmental biology. Shapes arise as a result of tightly controlled spatial variation in the rates and directions of tissue expansion over the course of development; therefore, quantifying these growth patterns could provide information about the underlying mechanisms of morphogenesis. Here we present a novel technique and computational tools for quantifying growth and shape changes in developing leaves, with a few unique capabilities. This includes the ability to compute growth from three-dimensional (3D) coordinates, which makes this the first method suitable for studying leaf growth in species or mutants with non-flat leaves, as well as small leaves at early stages of development, and allows us to simultaneously capture 3D shape changes. In the following, we apply these methods to study growth and shape changes in the first rosette leaf of Arabidopsis thaliana. Results reveal clear spatiotemporal patterns in growth rates and directionality, and tissue deformation maps illustrate an intricate balance involved in maintaining a relatively flat leaf surface in wild type leaves. Semi-automated tools presented make a high throughput of data possible with this method, and algorithms for generating mean maps of growth will make it possible to perform standardized comparative analyses of growth patterns between wild type and mutants and/or between species. The methods presented in this thesis will therefore be useful for studying leaf growth and shape, to further investigate the mechanisms of morphogenesis. RÉSUMÉ: Comment un organe acquiert sa forme particulière au cours du développement est une question intéressante mais largement non résolue. La forme d’un organe résulte de la façon dont les taux et directions de croissance de ses tissues varient dans l’espace et dans le temps. Quantifier les motifs de croissance est donc nécessaire pout élucider les mécanismes sous-jacents de la morphogenèse. Nous présentons ici une nouvelle méthodologie pour quantifier la croissance et les changements de forme dans les feuilles en développement. Cette méthodologie s’appuie sur le développement de nouvelles techniques expérimentales et de programmes informatiques, et présente des avantages uniques : la croissance de la surface des feuilles et le changement de forme peuvent être analysés en trois dimensions (3D), pour une longue période et de large déformations. De plus l’analyse de multiples échantillons permet de générer une cartographie moyenne des motifs de croissance à la surface des feuilles au cours de leur développement, ainsi qu’une description quantitative de la déformation des tissus sous l’effet de leur croissance. Dans cette thèse, nous présentons les résultats de croissance et de changements de forme de la première feuille de rosette d'Arabidopsis thaliana au cours de son développement. Les cartes moyennes de croissance révèlent des motifs spatio-temporels évidents tant pour les taux que pour les directions de croissance. De plus, la description de la déformation des tissus démontre l'équilibre complexe impliqué dans le maintien d'une surface relativement plane dans les feuilles. La méthode proposée et les logiciels associés permettra d’effectuer des analyses comparative de la croissance entre feuilles de type sauvage et feuilles de mutants aux formes altérées, afin d’élucider les mécanismes de la morphogenèse foliaire.

Resumen

How patterns arise from an apparently uniform group of cells is one of the classical problems in developmental biology. The mechanism is complicated by the fact that patterning occurs on a growing medium. Therefore, changes in an organism’s size and shape affect the patterning processes. In turn, patterning itself may affect growth. This interaction between growth and patterning leads to the generation of complex shapes and structures from simpler ones. Studying such interactions requires the possibility to monitor both processes in vivo. To this end, we developed a new technique to monitor and quantify vein patterning in a growing leaf over time using the leaves of Arabidopsis thaliana as a model system. We used a transgenic line with fluorescent markers associated with the venation. Individual leaves are followed in many samples in vivo through time-lapse imaging. Custom-made software allowed us to extract the leaf surface and vein pattern from images of each leaf at each time point. Then average spatial maps from multiple samples that were generated revealed spatio-temporal gradients. Our quantitative description of wild type vein patterns during leaf development revealed that there is no constant size at which a part of tissue enclosed by vasculature will become irrigated by a new vein. Instead, it seemed that vein formation depends on the growth rate of the tissue. This is the first time that vein patterning in growing leaves was quantified. The techniques developed will later be used to explore the interaction between growth and patterning through a variety of approaches, including mutant analysis, pharmacological treatments and variation of environmental conditions.

Resumen

Variability in the relationship between tree leaf area (TLA) and selected stem measurements was examined in three Douglas-fir stands (Pseudotsuga menziesii (Mirb.) Franco, var. menziesii) that were less than 50 years-old, spaced to approximately 550 to 650 stems/ha, and differed in soil moisture and nutrients. Attention was given to the effect of mean annual ring width (MARW), cross-sectional area of the live bark (ALB - a surrogate measure of relative nutrient storage in the stem), and cross-sectional area of the most recent annual rings equal in number to the number of whorls in the live crown (ALC), on variability in the relationship between TLA and cross-sectional area of sapwood (ASW). At breast height, basal area, ASW, and cross-sectional area of sapwood plus live bark (ASWLB) were not linearly related to TLA, and linear regression equations using log transformed variables varied significantly between sites. Nonlinear regression equation for ASW at breast height was: TLA = 0.064ASẆ¹•³³ (I² = 0.856). Including D (the distance between breast height and the center of the live crown) in the nonlinear equation, did not significantly improve the regression. Tree leaf area prediction models using stem measures from the base of live crown (blc) had higher adjusted R² values than models using stem measures from breast height. At the blc, basal area, ASW, and ASWLB were linearly related to TLA (adjusted R² = 0.926, 0.908, and 0.934, respectively). Multiplying ASW by MARW did not improve the fit of the regression models. Multiplying ASW by ALB improved the linearity of the relationship of ASW at breast height to TLA. The best fitting TLA model overall used the product of ASW at blc and ALB at blc as the independent variable (adjusted R² = 0.967). The results indicate that research into the allometric relationship of TLA to stem measures should give consideration to more than hydraulic measures and include measures of bark function. At breast height and the blc, the independent variable ALC was linearly related to tree leaf area and had higher adjusted R² values than did ASW. In most trees the ALC stem measure was found to include a portion of heartwood area. The strong relationship between TLA and ALC suggests that a given transpiring leaf mass or area is related to a proportional amount of conducting stemwood and physical support stemwood. A quick alternative approach for estimating individual tree leaf area using photographs taken at fixed distance and angle from the target tree did not result in a reliable tree leaf area prediction technique. The difficulty of obtaining views of the tree crown which were not obstructed by adjacent tree crowns was the major obstacle. Using a fixed distance and camera angle was a problem because of variable tree heights. However, altering these fixed positions introduced additional variation into the tree leaf area estimation. Mean specific leaf area (SLA) varied significantly by site, needle age class, and crown position. Mean SLA per needle age class per branch can be predicted with 95% confidence and a 10% allowable error using six 10-needle samples.

Resumen

Physiological characteristics of three cotton genotypes were evaluated for their responses to plant aging under high and low planting density (HPD and LPD) treatments. In addition, the relationship of these physiological characteristics to fruit production were determined. Two genotypes are sympodia producing, "Pima S-6" (Gossypium barbadense L.) and "Deltapine 90" (DPL-90) (G. hirustum L.). The third, a "Cluster Selection" (G. barbadense L.) does not produce sympodia. These genotypes were grown on a Gila sandy loam soil at Tucson, Arizona in 1984 and 1985. Plant physiological characteristics were measured under field conditions at 5 intervals. Leaf physiological characteristics were determined at 7 different leaf ages. LPD treatment significantly reduced total dry weight (TDW), fruit dry weight (FDW), and leaf area index (LAI) in each genotype, but reductions were more pronounced in Pima S-6 and Cluster Selection in both seasons. However, LPD treatment significantly increased plant leaf area, but had no effect on specific leaf weight (SLW), petiole nitrate-nitrogen (Petiole NO₃-N) concentration, leaf area ratio (LAR), and fruiting index (FI), for all genotypes in both seasons. The aging patterns of all physiological characteristics were similar in both planting density treatments, regardless of genotype or season. Regression analyses showed that photosynthetic rate was curvilinearly correlated with leaf age (r² = 0.65 to 0.77, P < 0.01). However, petiole NO₃-N concentration decreased linearly with increasing leaf age (r² = 0.90 to 0.91, P < 0.01). Photosynthetic rate increased curvilinearly with increasing petiole NO₃-N concentration (r² = 0.61 to 0.79, P < 0.01). SLW was not correlated with leaf age, or other leaf physiological characteristics regardless of planting density treatment in 1985. TDW, FI, and LAI were directly related, while petiole NO₃-N concentration and LAR were inversely related to fruit production for all genotypes in both seasons. Multiple regression analyses showed that excluding planting density treatment effect, TDW, FI, and LAI were the most important variables incorporated for fruit prediction in both seasons.

Resumen

Several mechanisms have been proposed to explain the process of vein pattern formation in plant tissues. The most widely accepted amongst biologists is the canalization hypothesis, derived from pea root and stem experiments. According to this hypothesis, a signal, thought to be the phytohormone auxin, is transported polarly from cell to cell from the shoot to the root and is canalized progressively into narrow channels of high auxin fluxes that later differentiate to become vascular tissue. In this project, we set out to test whether auxin canalization drives vein pattern formation, using Arabidopsis thaliana mutants with increased auxin transport (max4-1, max3-9, max2-1 and max1-1). We predicted that the mutants would have distinct vein patterns and especially different angles between the primary and secondary veins, compared to the wild type. First rosette leaves of 15 plants per genotype were harvested for analysis each day from 7 to 17 days after sowing, giving a total of eight hundred twenty-five leaf samples to analyze. Venation patterns were extracted and analyzed using custom-made software written with Matlab. Overall, compared with the wild type, mutants with the highest auxin transport (max4-1 and max3-9) had different vein patterns at early developmental stages, confirming a role for auxin transport in vein patterning. However, veins of mutants and wild type connected at similar angles, which is not consistent with the auxin canalization hypothesis, as originally formulated.

Resumen

Since 2011, China has dramatically grown its robotics sector as part of its mission to achieve technological leadership. The Chinese government has encouraged this growth through incentives and, in some cases, subsidies. Patents in robotics have surged, particularly at Chinese universities; by contrast, private companies comprise the bulk of robotics patent filers around the world. China has also seen a corresponding growth in robotics purchasing and active robotics stock. This data brief explores the trends in robotics patent families published from China as a measure of robotics advancement and finds that China is on track to emerge as a world leader in robotics.

Resumen

The purpose of this review is to assist FCDO in understanding the evidence of impact and any valuable lessons regarding the effect equitable quality education can have on ‘open society’. The search revealed that there is a considerable volume of evidence which focuses on education’s ability to reduce poverty, increase economic growth, boost employability and achieve better health outcomes. There is less which focuses on the aspects of ‘open society’ as defined in this paper. The scope of this review was narrowed to focus upon areas of the ‘open society’ definition where the most evidence does exist, given the timeframe for the review. The scope was narrowed to focus on: democracy, civic engagement, and social cohesion. The review of the literature found strong evidence that equitable quality education can have a range of positive impacts on democracy (specifically, its institutions and processes), civic engagement and social cohesion. There is a considerable body of evidence which indicates that there is a correlation between equitable quality education and benefits to societies (more peaceful, higher levels of trust, greater participation in politics, etc). However, there was no clear evidence that investment in equitable quality education directly leads to positive societal outcomes. This is because there are so many other factors to account for in attempting to prove causation. The lack of rigorous studies which attempt to attribute causation demonstrates a clear evidence gap. It is important to note that education systems themselves are politicised and cannot be divorced from the political process. The extent to which education can impact positively on open society depends a great deal on the value education has within the political system in which it is operating.

Resumen

As the State of California continues to grow, demand for enhanced infrastructure such as roadways and highways escalates. In view of the current average highway lifespan of 15–20 years, the improvement of asphalt binders leads to material sustainability by decreasing required maintenance and increasing the lifespan of roadways. In the present investigation, enhancement of asphalt binder properties was achieved by different methods of mixing varying compositions of graphene nanoparticles with an SBS polymer and asphalt binder. Additionally, experimental evaluation and comparison of the rheological and mechanical properties of each specimen is presented. Graphene nanoparticles have attracted great curiosity in the field of highway materials due to their incredible rigidity, even in small quantities. Addition of as little as 1.0%nanoparticles in combination with polymers in an asphalt binder is expected to increase the rigidity of the material while also maintaining the beneficial polymer characteristics. Evaluation of the effect of the mixing design established that the methods for application of graphene to the polymer-modified asphalt binder are critical in the improvement of a roadway, resulting in resistance to premature aging and strain from constant road operation.

Resumen

The 12 northeastern states form a diverse region producing more than $21 billion yearly in agricultural commodities. The Northeast region contains the seven most densely populated states and leads the nation in direct-to-public farm sales. Animal agriculture is important, particularly dairy and poultry. About half of the field crops and pasture grown in the Northeast are for animal feed. Horticulture and perennial fruits are also a relatively large portion of total plant production. Overall, farms in the Northeast are usually smaller in size and organic production is higher i comparison to other regions. About 21% of land in this region is farmland (6% of the national total), and 62% of land is classified as timberland.
