“…These differences may be of considerable agronomic importance during periods of moisture stress. The restriction of white clover roots to the surface of acid soils means the plant is prone to premature wilting during dry conditions compared to an acid-tolerant legume such as Lotus (Lowther, 1980). Better access to subsoil moisture would prolong growth of white clover as soils dried.…”

An aluminium (Al) tolerant genotype of white clover was compared with an Al susceptible genotype in artificial soil profiles in which exchangeable A1 increased with depth. The tolerant genotype had a greater proportion of its root mass deeper in the soil than the susceptible genotype. Nitrogenase activity showed a similar pattern. Shoot A1 concentration did not vary between the genotypes but root AI in the susceptible line was twice that in the tolerant genotype. Plant potassium content in the susceptible line was relatively less, probably in response to higher aluminium content.

“…Because the Altolerant clover selections had been shown to grow their roots deeper into Al-toxic soil (Crush & Caradus 1992), it was anticipated that the Altolerant clover lines would have an advantage over the Al-susceptible lines under dry conditions. This was based on Lowther's (1980) observation of white clover wilting and Lotus remaining turgid under dry conditions on these acid soils. The vigour score in March 1999 tended to indicate higher scores for the Al-tolerant clover selections under the prevailing dry conditions.…”

“…After cessation of the fertiliser applications, herbage yields and legume content were maintained at higher levels in the Lotus plots than in clover plots. On these acid soils white clover wilted in dry conditions, suggesting that clover roots were restricted to the surface by the soil acidity (Lowther 1980). Although Lotus can be intensively grazed and remain persistent when edaphic conditions limit growth of companion species (Scott & Mills 1981;Sheath 1981), it is vulnerable to frequent and/or severe grazing if competition from companion plants is increased (Sheath 1980).…”

Growth of 15 legumes was monitored for 3 years on 3 Otago upland soils with 11, 45, or 70 µg g -1 extractable soil aluminium (Al). Lotus pedunculatus and L. corniculatus produced the greatest dry matter over the 3 years, with L. pedunculatus producing superior yields at intermediate and high soil Al sites. Within white clover, types selected for Al tolerance produced similar yields to types selected for Al susceptibility, and four commercial white clover cultivars and an alsike clover (Trifolium hybidum). Caucasian clover (T. ambiguum) spread by rhizomes at the high Al site, but neither Lotus species spread from the planted row. Some white clovers showed limited spread. It is concluded that optimising performance of Lotus and Caucasian clover on these soils will be a more productive strategy than breeding for Al-tolerance in white clover. A00037

“…Neste estudo, esse cultivar apresentou também um sistema subterrâneo mais superficial, com raízes mais curtas e bifurcadas e sóboles densamente enraizados, características de plantas tolerantes a solos ácidos e de baixa fertilidade, conforme descrito por Wedderburn & Gwynne (1981), e de espécies adaptadas a solos pobres em fósforo e com alto teor de umidade (Lowther, 1980;Davis, 1981). As diferenças entre o comprimento e a distribuição das raízes explicam a maior persistência de Lotus, em comparação à alfafa, a solos rasos e mal drenados (Seaney & Henson, 1970), característica importante, especialmente na comparação de genótipos.…”

RESUMO -Este trabalho foi realizado com o objetivo de comparar cultivares de Lotus corniculatus L. (cv. São Gabriel, cv. ARS2620) e L. uliginosus Schkuhr (cv. Maku) por meio da análise do desenvolvimento morfológico. As plantas foram cultivadas em vasos, colhidas aos 90, 120, 150, 180 e 210 dias após a semeadura e avaliadas por medidas lineares e de peso, volume, área e contagem. Os dados foram submetidos à análise de regressão em função dos dias de crescimento. Os cultivares apresentaram a mesma tendência temporal quanto à estatura, ao volume radical e à massa seca (MS) aérea, mas diferiram quanto à grandeza das alterações. O acúmulo de MS (g/planta) foi superior nos cultivares Maku (15,0) e S. Gabriel (14,0) em relação ao cultivar ARS2620 (11,0). Os cultivares S. Gabriel, Maku e ARS2620 diferiram quanto ao diâmetro da planta (96,7; 80,7; 68,5 cm), ao diâmetro da coroa (6,5; 15,7; 8,1 mm), ao comprimento da massa radical (37,8; 29,2; 40,4 cm) e ao número de hastes da coroa (37,8; 29,2 e 40,4). O sistema subterrâneo foi mais vigoroso no cultivar Maku, que produziu mais MS de sóboles (16,3) em relação aos cultivares ARS2620 (4,7) e São Gabriel (2,0), mostrando ser potencialmente mais persistente em condições de pastejo. Palavras-chave: análise de crescimento, Lotus corniculatus, L. uliginosus, sóboles Morphological development of Lotus spp. with different growth habitABSTRACT -This work aimed to compare cultivars of Lotus corniculatus L. (cv. São Gabriel, cv. ARS2620) and L. uliginosus Schkuhr (cv. Maku) through the morphological development analysis. The plants were cultivated in pots and they were harvested at 90, 120, 150, 180, and 210 days after seeding being evaluated by linear, weight, volume, area, and count measurements. Data were submitted to regression analysis as a function of growth days. Cultivars had the same temporal trend for height, root volume, and shoot dry matter (DM), but differed in terms of the magnitude. The DM accumulation (g/plant) was greater for the cvs. Maku (15.0) and S. Gabriel (14.0) in relation to cv. ARS2620 (11.0). The cvs. S. Gabriel, Maku, and ARS2620 differed respectively for plant diameter: 96.7, 80.7, and 68.5 cm; crown diameter: 6.5, 15.7, and 8.1 mm; root mass extension: 37.8, 29.2, and 40.4 cm; crown stem number: 37.8, 29.2, and 40.4. The underground system was more vigorous in the cv. Maku, which produced more soboles MS (16.3) in relation to cvs. ARS2620 (4.7) and São Gabriel IntroduçãoO cornichão (Lotus corniculatus L.) é uma leguminosa forrageira de grande importância em diversos países, especialmente o Uruguai, onde é utilizada no melhoramento de extensas áreas de pastagens naturais. É uma espécie perene que pode persistir na pastagem por meio da sobrevivência da planta-mãe e por ressemeadura natural. A durabilidade é extremamente dependente do vigor e da sanidade da coroa, que se localiza entre a raiz e o caule, delimitada pelo nó cotiledonar (Marques-Ortiz et al., 1996). No Brasil, o único cultivar disponível comercialmente é o cv. São Gabriel, resultante de ...
