“…Marinus and Bodlaender (1975) observed that foliar growth increased with temperature at low ten1peratures and Midmore (1984) andVander Zaag et al (1986) observed that foliar growth decreased with tetnperature at high temperatures. MacKerron and Waister (1985) linearly correlated leaf expansion from emergence to temperature above a base temperature of2.4 °C, Spitters (1987) and Spitters and Schapendonk ( 1990) used a similar approach with a base temperature of 2 °C.…”

Abstract. A model 'LINTUL-POT ATO' is described which bases total dry matter production on light use efficiency of intercepted light by a potato crop. The course of light interception by green leaves initially is temperature-sum dependent and is also steered by influences of daylength and temperature on assimilate partitioning. Dry matter allocation to the foliage, which determines the final length of the growing period, is determined by a day length and temperature dependent period between emergence and tuber initiation and subsequent partitioning of dry matter to the tubers. Once the tuber daily growth rate equals total crop dry matter accumulation, no more foliage is formed and the crop senesces faster at higher temperatures. The aim of this paper is to explain effects of temperature and daylength on total tuber production from the effects of these environmental factors on the underlying processes. The relative effect of temperature on rates of emergence, light use efficiency, tuber initiation and tuber growth, and, the effect of daylength on development rate until tuber initiation are represented quantitatively. Potential tuber production at some temperature and day length regimes is calculated exploratively and compared with results from the literature. The model can be used to simulate tuber dry matter production in specific environments and to select cultivars for such environments with suitable temperature and daylength reactions on tuber initiation and dry matter partitioning so as to maximise yields.

“…Crop senescence takes place earlier at higher temperatures (Menzel 1985a) although the total length of the growing period may last longer because the total period of leaf formation may increase (Marinus and Bodlaender 1975). Leaf longevity has been recorded to last between 1440 and 1760 ocd (Vos and Oyarzun 1987).…”

“…O maior desenvolvimento foliar aliado às condições de alta temperatura na casa-de-vegetação (estresse térmico), podem ter contribuído para a redução dos teores de amido e massa seca. O estresse térmico diminui os fotoassimilados disponíveis no desenvolvimento da planta e partição nos tubérculos (DAM et al, 1996;PRANGE et al, 1990), e reduz a translocação dos fotoassimilados para os tubérculos (HUGHES, 1974;MARINUS & BLODAENDER, 1975). Para os teores de açúcares redutores foi também verificada interação entre doses de boro e cultivares tanto no LV (Figura 7) como no CX (Figura 8).…”

RESUMOO trabalho foi desenvolvido com o objetivo de avaliar a produtividade e qualidade de tubérculos de batata em resposta ao boro em amostras de um Latossolo Vermelho (LV) e de um Cambissolo (CX). O delineamento experimental foi o de blocos casualizados, em esquema fatorial 4 x 2, constituído de quatro doses de boro (0,0; 0,75; 1,50 e 3,0 mg dm -3 ) e duas cultivares de batata (Asterix e Monalisa), com três repetições. Foram avaliados a produtividade, a massa seca, teores de amido, açúcares redutores e açúcares totais dos tubérculos. As doses crescentes de boro aumentaram a produtividade principalmente para a cultivar Asterix, cultivada no LV com a dose de 2,19 mg dm -3 de boro. No LV, a cultivar Asterix também apresentou maiores porcentagens de massa seca e amido nos tubérculos, enquanto os teores de açúcares redutores reduziram-se com o aumento de boro nas duas cultivares. No CX, a produtividade foi menor que no LV, provavelmente, devido ao alto teor de silte do solo que dificultou a formação dos tubérculos. A Asterix foi 108% mais produtiva e 37% mais exigente em boro, quando comparada à Monalisa. Termos para indexação:Solanum tuberosum L, micronutrientes, massa seca, amido, açúcares. ABSTRACTThe experiment was carried out in a greenhouse, using two soils Latosol (LV) and Cambisol (CX) to evaluate the effects of boron rates on yield and tubers quality for two potato cultivars, Asterix and Monalisa. The experimental design was a randomized blocks in a 4 x 2 factorial arrangement with three replications, using four boron rates (0.0, 0.75; 1.50 and 3.0 mg dm -3 ) and two potato cultivars (Asterix and Monalisa). Two soil types were used; Latosol and Cambisol. Yield, dry matter, starch, reducing sugars and total sugars tuber contents were evaluated. Increasing boron rates improved tuber yield, reaching maximum yield on Red Latosol at 2.19 mg dm -3 of boron. For Asterix cultivar, also presented the highest percentages of dry matter and starch in tubers on a Red Latosol. Reducing sugar content decreased with boron rates in Red Latosol. For both cultivars, in Cambisol, yield was lower than Red Latosol, due to the high silt content in Cambisol, making difficult tuber formation. Asterix cultivar presented 108% greater yield than Monalisa in Cambisol, although requiring 37% more boron.

“…LAFTA & LORENZEN (1995) constataram que plantas de batata cultivadas em câmaras de crescimento sob temperaturas do ar de 31/ 29ºC (dia/noite) apresentaram redução na produção de matéria seca de 44 a 72% depois de quatro semanas, em comparação com um regime de temperatura do ar de 19/17°C (dia/noite). Altas temperaturas do ar aumentam o período de crescimento das folhas, o que causa redução na taxa de translocação de carboidratos para os tubérculos (MARINUS & BODLAENDER, 1975). Temperaturas do ar acima da ótima resultam em plantas de batata mais altas, com elevada massa seca de hastes e folhas menores (PRANGE et al, 1990;LAFTA & LORENZEN, 1995), e reduzida produção de tubérculos em muitas cultivares (KHEDHER & EWING, 1985).…”

“…Em geral, para que ocorra a máxima taxa de desenvolvimento, a temperatura do ar deve estar entre 14 e 22°C (MARINUS & BODLAENDER, 1975). A temperatura média para a cultura da batata está entre 10 e 20°C, e a faixa ideal para a indução e o crescimento dos tubérculos e a produção de matéria seca está entre 15 e 20°C (ANTUNES & FORTES, 1981).…”
