“…Osawa (18) also stated that stimulative effects of 1000 or 2000 ppm NaCI on the vegetative growth of such crops, pak-choi, cabbage, radish, chinese cabbage, celery and tomato might be due to Na in most cases. Similar results were noted by other investigators (9,12,21). Salt tolerance values should also be considered in the portion of the plant to be marketed.…”

“…For example, it has been reported that salinity delays germination, but does not appreciably reduce the final percentage of germination (12,16,19). In the present experiments diluted sea water containing 2000 ppm Cl decreased the percentage of tomato seed germination 6 days after starting the test, but did not affect the final percentage of germination 12 days after starting the test.…”

“…These Cl concns were lower than those that resulted in maximum growth of tops in each culture. The effect of salinity on fruit yields does not always parallel vege- tative growth (12,17). Nieman (15) considered that photosynthetic activity per unit leaf area was not suppressed by NaCI and photosynthate is generally not a limiting factor in the growth of salt-stunted plants.…”

Experiments were conducted to determine the effect of diluted sea water on the germination, growth and yield of tomatoes. 1) The germination percentage of tomato seeds decreased even at 100 ppm Cl 2 days after the test was started. The germination percentage in 6 days was not significantly different among 0 to 1000 ppm Cl. Yet, germination at 2000 and 3000 ppm Cl was 80.5 and 21.5%, respectively, and was significantly lower than among 0 to 1000 ppm Cl. 2) Transpiration rate of tomatoes transferred to diluted sea water with Hoagland's soln decreased with increasing sea water concns. 3) Tomato seedlings were grown in water culture with sea water diluted with Hoagland's soln for 40 days from the 2 leaf stage. The fresh wt of leaves was greater at 250 and 500 ppm Cl than that at 0 and 100 ppm Cl. The fruit wt was greatest at 0 ppm Cl. One plant died at 6000 ppm Cl. The osmotic potential of leaves decreased with increasing sea water concns. 4) Tomatoes were grown in sand culture with sea water diluted with Hoagland's soln. Chlorosis and necrosis occurred on the lower leaves at 2000 ppm Cl. These symptoms were markedly severe at 3000 ppm Cl and developed from lower to upper leaves. One plant died during the growing period at 3000 ppm Cl. Fresh wt of leaves and fruit yields decreased with increasing sea water concns. The leaf content of Cl and Na increased with increasing sea water concns. 5) Tomatoes were grown in soil culture with sea water diluted with tap water. The marginal necrosis in lower leaves was found at the higher concn of sea water. However, plants did not wither even at 3000 ppm Cl. Fresh wt of leaves and fruit yields decreased as sea water concns increased. The content of N, P, K, Na, Mg and Cl in the leaves tended to increase with increasing sea water concns. The content of Cl, exchangeable Na and Mg, and EC value of the soil increased as sea water concns increased.

“…O efeito da salinidade sobre a massa de matéria seca das raízes, da parte aérea e sobre a área foliar foi consistente com os resultados obtidos em outros estudos, nos quais o excesso de NaCl nos substratos reduziu o crescimento e o desenvolvimento dessas variáveis em várias espécies de interesse agronômico (Lunin et al, 1961;LaHaye & Epstein, 1971;Greenway & Munns, 1980;Cramer & Läuchli, 1986;Zaffaroni et al, 1988;Salim, 1989;Akhavan-Kharazian et al, 1990;Andriolo et al, 2005;Lima & Bull, 2008 notadamente devido ao aumento da espessura das célu-las, ocorrido por um possível ajuste osmótico, resultante da concentração de solutos, contribuindo para expansão celular e manutenção do turgor (Sanchez Blanco et al, 1991;Mahmood & Quarric, 1993). Esse resultado também pode ser justificado admitindo-se a possibilidade de ocorrência de um ajustamento mecânico devido ao aumento da extensibilidade da parede celular, contrabalanceando a redução do turgor celular, mantendo a taxa de crescimento da folha, como verificado por Newmann et al (1988) (Araújo et al, 1994).…”

Selection of Phaseolus vulgaris L. varieties for tolerance to salt stress based on growth variablesThis study aimed to evaluate and select varieties of bean (Phaseolus vulgaris L.) for tolerance to salt stress and to identify, using bean varieties with different degrees of tolerance, variables to aid in the screening of salt-tolerant varieties, regardless of the mechanism used by the plant. The experiments were conducted in a greenhouse. Initially, 48 P. vulgaris varieties were evaluated (allocated in subplots) at two salinity levels (distributed in the plots): normal nutrient solution (NNS) at 0.81 dS m -1 and test solution (TNS) at 5.6 dS m -1 , which was obtained by adding NaCl in a randomized block design with four replications. The dry weight of aerial part was used to calculate the percentage of Neste estudo objetivou-se avaliar e selecionar variedades de feijoeiro (Phaseolus vulgaris L.) quanto à tolerância ao estresse salino e identificar, usando variedades de feijoeiro com diferentes graus de tolerância, variáveis que auxiliem na discriminação de variedades de feijoeiro quanto à tolerância a esse tipo de estresse, independentemente do mecanismo apresentado pela planta. Os experimentos foram realizados em casa de vegetação. Inicialmente foram avaliadas 48 variedades de P. vulgaris (alocadas nas subparcelas) em dois níveis de salinidade (distribuídos nas parcelas): solução nutritiva normal (SNN) a 0,81 dS m -1 e a teste (SNT) a 5,6 dS m -1 , obtida pela adição de NaCl no delineamento experimental em blocos casualizados, com quatro repetições. A partir da massa seca da parte aérea calculou-se a relação percentual de crescimento alcançada na SNT relativo à SNN das variedades, que variou de 138,7 a 54,1%, discriminando-as de acordo com o critério de Scott-Knott em duas populações: uma com 14 variedades mais "tolerantes" e outra com 34 variedades, onde ficaram agrupadas variedades "moderadamente tolerantes" e "sensí-veis". Para identificar variáveis de crescimento que permitam selecionar feijoeiros quanto à tolerância ao estresse salino duas variedades tolerantes (Vermelho e CNF 5574), uma medianamente tolerante (FT 83-86) e uma sensível (LM 30074), classificadas no experimento anterior, foram cultivadas em solução nutritiva com cinco níveis de salinidade (0,81; 2,7; 4,6; 6,5; e 8,4 dS m -1 ). Analisando-se a massa seca da raiz, do caule, do pecíolo, das folhas e da parte aérea, a área foliar e a área foliar específica, concluiu-se que a área foliar específica foi o índice que efetivamente mais contribuiu para a discriminação das variedades de feijoeiro quanto à tolerância à salinidade. Palavras INTRODUÇÃOÉ reconhecida a existência de diferenças genéticas na tolerância a sais entre espécies e variedades dentro de determinada espécie, Essas diferenças podem ser usadas para identificar plantas mais tolerantes ao estresse salino.O método convencional de multiplicação de plantas, segundo Epstein & Rains (1987), tem sido a seleção e o melhoramento de variedades para alta produtividade, resistência a doen...

“…The EC of the irrigation water was increased by adding a concentrated solution of synthetic sea water (Lunin et al, 1961) to reservoir tanks filled with tap water. This solution was added until the measured EC i (Markson conductance meter model 72) value coincided with the required EC i value.…”

Although the effects of salinity on yield of tomato (Lycopersicon esculentum Mill.) grown under arid and semiarid conditions are well known, little information is available on the effects of salinity on crops grown in more humid conditions. In Florida, availability of high-quality water for irrigation may be reduced because of increased domestic consumption and sea water intrusion. Two greenhouse studies were conducted to determine the influence of irrigation system and water quantity and quality on the growth of tomato and snap bean (Phaseolus vulgaris L.). Bean plant heights and weights were greater with drip irrigation than with subirrigation. Bean seed germination percentage, plant height, and shoot weight decreased linearly with an increase in electrical conductivity of irrigation water (ECi) from 1 to 4 dS·m-1. Tomato leaf water potential and plant height decreased linearly with increasing salinity. Tomato stem and leaf weights were greatest at the intermediate salinity (2 dS·m-1) during initial growth, and stem weights decreased linearly with increased salinity during flowering. With drip irrigation, concentration of N for both crops decreased and concentration of P increased with an increase in water application from 0.75 to 1.5 times the estimated evapotranspiration rate (ETa). Tomato and bean tissue Na concentrations increased linearly with increased salinity. Total fruit yield and average fruit weight decreased linearly in tomato, and marketable fruit yield decreased quadratically with increased salinity.
