Crescimento radicular e nutrição de cultivares de algodoeiro em resposta à calagem

Abstract: ROOT GROWTH AND MINERAL NUTRITION OF COTTON CULTIVARS AS AFFECTED BY LIMINGABSTRACT -Cotton root growth is under genetic control but can be decreased by soil factors as Al toxicity and low Ca levels. Lime was applied to a Dark-Red Latosol (sandy loam) with 10% of base saturation, to raise base saturation to 30, 50 and 70%, in order to study the effects of liming on root growth and mineral nutrition of cotton (Gossypium hirsutum L., v. latifolium Hutch), cv. IAC 20, IAC 22 e CNPA-ITA 90 cultivares. The experime… Show more

“…In the present experiment, root length was increased by K fertilization up to 45 mg kg -1 , but was decreased by liming (Figure 4). Rosolem et al (1998) observed an increase in cotton root length when soil Ca was raised to 16 mmol c kg -1 but total root length was decreased, probably due to Zn deficiency when lime increased soil Ca up to 26 mmol c kg -1 . Considering the highest K rate, both root lengths with and without lime decreased as compared with 45 mg kg -1 of potassium.…”

“…Rosolem et al (2000) observed that liming, by decreasing Al toxicity, caused an increase in cotton root length and surface, which would favour K uptake. Rosolem et al (1998) observed that not only cotton root length, but also root diameter was increased by liming, which can also affect the rate of K reaching the roots by diffusion.…”

“…Porém, segundo Caines & Shennan (1999), a relação entre o uso eficiente de Ca e o crescimento de planta é muito complexa e pode envolver vários controles fisiológicos, como a capacidade de retranslocação interna de Ca compartimentalizado em membranas e órgãos celulares de armazenamento como retículo endoplasmático, cloroplastos e vacúolo. No entanto alguns autores como Rosolem et al (2000), Wutke et al (2003) e Silva et al (2004), em seus estudos constataram maior crescimento e rendimento de cultivares de feijoeiro quando do suprimento de cálcio às plantas em comparação a tratamentos onde este nutriente foi omitido.…”

“…Já para Rosolem et al (2000) os valores de saturação do solo por bases que proporcionaram máximo crescimento radicular foram de 50% para a cultivar IAC 22 e de 70% para cultivar CNPA-ITA 90, explicitando resposta diferenciada entre cultivares. Os autores verificaram não haver deficiência de zinco na parte aérea das plantas, entretanto, tal deficiência foi observada no sistema radicular em função da calagem.…”
