Resumo: | The objective of this study was to determine the response of plant transpiration and leaf growth to the fraction of transpirable soil water (FTSW) in potato and cassava clones. Three experiments were conducted with potato, two of them were in Spring, with plantings on 08/20/2008 (BAT1) and on 10/20/2008 (BAT2), and one experiment in Fall, with planting on 03/25/2009 (BAT3). Two experiments were conducted with cassava, with plantings on 09/11/2009 (MAN1) and on 09/08/2010 (MAN2). The experiments were conducted in 8 liter pots filled with soil inside a plastic house. Two potato clones (Macaca and SMINIA 793101- 3) and two cassava clones (Fécula Branca and Fepagro RS 13) were used. Soil water, represented by the FTSW, transpiration and leaf growth were measured on a daily basis during the period of soil drying. The threshold FTSW that starts to affect transpiration, which is an indicator of stomata closure, was 0.38, 0.47 and 0.28 for the clone Macaca and 0.48, 0.51 and 0.32 for the clone SMINIA793101-3 in BAT1, BAT2 and BAT3, respectively, whereas leaf growth decreased at a greater threshold FTSW for Macaca . These results indicate that the clone SMINIA793101-3 is more tolerant to soil water deficit than Macaca . For cassava, the threshold FTSW for transpiration was 0.45 in the clone Fécula Branca and 0.50 in the clone Fepagro RS 13 . The onset of reduction in leaf growth was at a FTSW of 0.51 in the clone Fécula Branca and 0.49 in the clone Fepagro RS 13 .When data were separated in days with low and high vapor pressure deficit at 3PM, threshold FTSW for transpiration and leaf growth changed in both species and within each species. These results confirm the genetic variability available in each species and are a reminder on the complex genotype and environment relationships that characterize agricultural crops. |

Foram realizados três experimentos com a cultura da batata, sendo dois na primavera (cultivo de safra), com plantios em 20/08/2008 (BAT1) e 20/10/2008 (BAT2) e um no outono (cultivo de safrinha), com plantio em 25/03/2009 (BAT3), e dois experimentos com a cultura da mandioca com plantio em 11/09/2009 (MAN1) e 08/09/2010 (MAN2). Os experimentos foram conduzidos em vasos de 8 litros preenchidos com solo e dispostos no interior de um abrigo plástico telado. Os clones de batata utilizados foram Macaca e SMINIA793101-3 e os clones de mandioca foram Fécula Branca e Fepagro RS 13. A água disponível, representada pela FATS, a transpiração e o crescimento foliar foram medidos diariamente durante o período de imposição da deficiência hídrica em cada experimento. Para a cultura da batata a FATS crítica que começa a afetar a transpiração, indicativo do início do fechamento estomático, foi de 0,38, 0,47 e 0,28 no clone Macaca e 0,48, 0,51 e 0,32 no clone SMINIA793101-3, para os experimentos BAT1, BAT2 e BAT3, respectivamente, enquanto o crescimento foliar começou a ser reduzido com um valor de FATS crítica maior para o clone Macaca, indicando que o clone SMINIA793101-3 é mais tolerante ao déficit hídrico no solo que o clone Macaca. Para a cultura da mandioca, a FATS crítica em que a transpiração começa a ser reduzida foi de 0,45 para o clone Fécula Branca e 0,50 para o clone Fepagro RS 13. O crescimento foliar começou a ser reduzido quando a FATS atingiu valores de 0,51 no clone Fécula Branca e 0,49 no clone Fepagro RS 13. Quando os dados foram separados em dias com baixa e alta demanda evaporativa do ar, representada pelo déficit de pressão de vapor do ar às 15 horas, houve diferença na FATS crítica que começa a afetar a transpiração e o crescimento foliar para as duas espécies e dentro de cada espécie. Estes resultados confirmam a variabilidade genética disponível em cada espécie e são um lembrete da complexa relação entre genótipo e ambiente que caracteriza as culturas agrícolas.Coordenação de Aperfeiçoamento de Pessoal de Nível Superiorapplication/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em Engenharia AgrícolaUFSMBREngenharia AgrícolaSolanum tuberosum L.Manihot esculenta CrantzDéficit hídricoFechamento estomáticoMelhoramento genéticoUmidade crítica no soloSolanum tuberosum L.Manihot esculenta CrantzWater deficitStomata closurePlant breedingThreshold soil moistureCNPQ::CIENCIAS AGRARIAS::ENGENHARIA AGRICOLATranspiração e crescimento foliar de clones de batata e de mandioca em resposta à fração de água transpirável no soloTranspiration and leaf growth of potato and cassava clones as a function of fraction of transpirable soil waterinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisStreck, Nereu Augustohttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4721150P1Heldwein, Arno Bernardohttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4788078U3Righi, Evandro Zaninihttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4761177E5Streck, Lucianohttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4794800T6Alberto, Cleber Maushttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4236721E6http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4778883J9Lago, Isabel5003000000084005003005005005003003b01ed40-f2a9-4cc8-9109-59e6f482b05dfb614ee8-8c4e-4cfa-82f4-e62f4ca88c899a4eada9-2d44-42ce-8d75-16ec472d6005180119c4-a314-4536-9fe5-20fc56a0078be305ec61-3310-4c4e-8ebd-44b55f442451ed22747e-b107-4eae-869a-721f965c0198info:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALLAGO, ISABEL.pdfapplication/pdf11974177http://repositorio.ufsm.br/bitstream/1/3586/1/LAGO%2c%20ISABEL.pdf380997e2ad31a0bd333f60e6b178b017MD51TEXTLAGO, ISABEL.pdf.txtLAGO, ISABEL.pdf.txtExtracted texttext/plain183969http://repositorio.ufsm.br/bitstream/1/3586/2/LAGO%2c%20ISABEL.pdf.txt4176c102d2be80c21082d05aa4c8a547MD52THUMBNAILLAGO, ISABEL.pdf.jpgLAGO, ISABEL.pdf.jpgIM Thumbnailimage/jpeg5028http://repositorio.ufsm.br/bitstream/1/3586/3/LAGO%2c%20ISABEL.pdf.jpg0db876c6e05b4a181089876c2cc558d0MD531/35862022-03-02 16:54:31.204oai:repositorio.ufsm.br:1/3586Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2022-03-02T19:54:31Biblioteca Digital de Teses e Dissertações do UFSM - Universidade Federal de Santa Maria (UFSM)false |
