This article-based thesis focuses on the formation of vocational knowing within adult and upper secondary floristry education in Sweden. Three articles explore classroom interaction and assessment actions; a fourth considers changes in vocational subject matter during the period 1990–2015. While the first three articles draw on empirical data in the form of video and audio recordings in combination with participant observation, the fourth is based primarily on material-based interview data. All four articles share a sociocultural perspective on educational practice (Wertsch, 1998; Säljö, 2011, 2013) and a relational view of knowing (e.g., Carlgren, 2015; Molander, 1996), in combination with the use of conversation analysis (Goodwin &amp; Heritage, 1990; Sahlström &amp; Melander, 2010) as a tool to illuminate the formation of vocational knowing. The interaction between teacher, student, and floral arrangement is foregrounded to facilitate analysis of the formation of vocational knowing. The results contribute to our understanding of the schooling of the gaze (Goodwin, 1994; Grasseni, 2009, 2011) as appropriated by participants in the interaction. Floristry vocational knowing is shown to evolve in the temporal dimension, encompassing (a) financial and aesthetic values, (b) verbal and non–verbal communication, (c) botanical material and tools, and (d) making. The respective roles and interrelations of these four components of vocational knowing in floristry are discussed. The contribution of the thesis is twofold. First, these articles contribute to the understanding of vocational education through close appraisal of the formation of vocational knowing. Second, in exploring the previously under-researched field of Swedish floristry vocational education, the thesis bridges a gap in existing knowledge of the evolution of Swedish vocational education. As floristry education is little researched internationally, the thesis also contributes to the wider body of international research. / <p>At the time of the doctoral defense, the following papers were unpublished and had a status as follows: Paper 3: Submitted.

Entender os mecanismos de defesa das plantas de crisântemo em resposta à deficiência hídrica é importante no processo produtivo desta cultura. O objetivo neste trabalho foi determinar a resposta da transpiração e do crescimento foliar, de cultivares de crisântemo (Dendranthema grandiflora Tzvelev.), ao conteúdo de água disponível em substrato, representado pela fração de água transpirável em substrato (FATS). Foram realizados dois experimentos, no setor de floricultura do Colégio Politécnico da UFSM, utilizando-se o delineamento inteiramente casualizado, sendo um no fim da primavera de 2011, com aplicação dos tratamentos a partir de 09/12/2011 - e um no inverno de 2012, com aplicação dos tratamentos a partir de 07/07/2012. As plantas foram cultivadas em vasos de 2,8 litros, preenchidos com substrato e dispostos no interior de uma casa de vegetação com controle de temperatura. As cultivares de crisântemo utilizadas foram a Cherry White (de vaso), Repin Bronze (de corte), Apple Valley (de vaso) e Calábria (de corte). A FATS, a transpiração e o crescimento foliar foram determinados diariamente durante o período de imposição da deficiência hídrica em cada experimento. A FATS crítica no crisântemo que começa a afetar a transpiração, indicativo do início do fechamento estomático, é de 0,63 para a cultivar Cherry White; 0,60 para a cultivar Repin Bronze; 0,53 para a cultivar Apple Valley; e 0,51, para a cultivar Calábria. A redução do crescimento foliar inicia com um valor de FATS crítica de 0,67 para a cultivar Cherry White; 0,69 para a cultivar Repin Bronze; 0,59 para a cultivar Apple Valley e 0,54, para a cultivar Calábria. As cultivares Cherry White e Repin Bronze apresentam maior tolerância ao déficit hídrico do que as cultivares Apple Valley e Calábria. O crescimento foliar começa ser reduzido com um valor de FATS crítica maior do que o valor de FATS crítica em que a transpiração começa a ser reduzida. A deficiência hídrica afeta negativamente as variáveis de crescimento e de desenvolvimento de cultivares de crisântemo. / Understand the defense mechanisms of plants of chrysanthemum in response to water stress is important in the production process of this crop. The objective of this study was to determine the response of the plant to transpiration and leaf growth of chrysanthemum cultivars (Dendranthema grandiflora Tzvelev.), related to the available water content in the substrate, represented by the fraction of transpirable substrate water (FTSW). Two Greenhouse experiments were conducted in the flower sector of the Polytechnic College UFSM, using a completely randomized design. One started end of spring of 2011, with application of treatments on 09/12/2011 and the second in winter 2012, with application of treatments on 07/07/2012. Plants were grown in 2.8 liter pots filled with substrate and arranged inside a greenhouse with temperature control. The chrysanthemum cultivars were Cherry White (potted), Repin Bronze (for cut), Apple Valley (potted) and Calabria (for cut). The FTSW, transpiration and leaf growth were determined daily during the period of imposition of water deficit in each experiment. The threshold FTSW for Chrysanthemum that begins to affect transpiration, is an indicative of early stomatal closure and was 0.63 for the cultivar Cherry White, 0.60 for Repin Bronze, 0.53 for Apple Valley and 0.51, for Calabria. Leaf growth began to be reduced at a threshold FTSW of 0.67 for Cherry White, 0.69 for Repin Bronze, 0.59 for Apple Valley and 0.54, for Calabria. Cultivars Cherry White and Bronze Repin proved to be more tolerant to water deficit than the cultivars Apple Valley and Calábria. The reduced leaf growth starts with a threshold FTSW value larger than the threshold FTSW value related to reduced transpirations. The water deficit negatively affected the variables of growth and development of the chrysanthemum cultivars.

One spring afternoon in 1631, the Norwich Society of Florists held a feast to celebrate and display its exquisite flowers. The celebration included an entertainment written just for the occasion—Ralph Knevet's quirky play about a war among flowers. Early modern florists were not the sort of people who sold cut flowers in shops; rather, they were experts in floriculture who applied this knowledge to cultivate new flowers. Norwich was already renowned for its gardens, but flowers soon became even more significant. Rhodon and Iris was performed just before tulipomania, a frenzy of tulip cultivation lasting from c.1634 – 1637. During this period, florists grew elaborate multi-coloured flower bulbs that sold for extremely high prices. In other words, the florists' feast and Knevet's play emerged when flowers were important to the economy and identity of Norwich. My thesis presents an open-access, digital critical edition of Rhodon and Iris encoded in TEI-P5. This edition offers an old-spelling transcription of the 1631 playbook, a modernized text with annotations, and a critical introduction. Responding to the need for more editions of non-canonical early modern plays, my research widens the otherwise Shakespeare-centric canon and helps make more early modern drama accessible to student readers. Rhodon and Iris also merits critical attention on its own grounds: an example of Caroline occasional drama, the play experiments with convention and offers a rare glimpse into the Society of Florists. My thesis approaches the play with special interest in editorial praxis, ecotheory, and the history of floriculture. The florists' feast delighted audiences and participated in a tradition of floral celebrations—one reaching, at least, from the ancient Roman ludi Florales to the modern Netflix series The Big Flower Fight. / Graduate / 2021-06-26
