“…Dry weight of leaves of Filiz 99 remained similar to control values with KNO 3 but decreased in experimental groups with potassium acetate, which caused more severe reduction in growth parameters of both cultivars than KNO 3 (Table 3). Our findings support other results for the salt-tolerant plant Salvadora oleoides (Ramoliya and Pandey 2002). The reduction in LDW may relate to decreasing carbon dioxide (CO 2 ) uptake due to inhibition of stomatal regulation accompanying decreases in leaf expansion and assimilation by the leaf cells and resulting in loss of weight.…”

“…The available studies also record decreases in chlorophyll content, number and length of internodes and nodes, and, related to this, number of flowers and reduction in weight of plant organs such as leaves, shoots, and roots. The development of roots has been decreased, and inhibition of lateral root development also occurred (Parida, Das, and Mittra 2004;Kaya et al 2003;Singh et al 2003;Ramoliya and Pandey 2002;Sairam, Rao, and Srivastava 2002;Bolarin et al 2001;Katerji et al 2000;Carvajal et al 1998;Rodriguez et al 2005;Turan et al 2009). However, not all of our results were consistent with the existing literature.…”

“…The available literature records that salt stress in various plants leads to reductions in growth parameters such as inhibition of plant height; reduction in number of leaves; inhibition of leaf extension and development (assimilation surface); thinner epidermal and mesophyll layers in leaves; decreased rate of CO 2 uptake; difficulties of stomatal regulation; reduction of transpiration rate, chlorophyll content, and cell division and development; reduction of internode numbers and internodal length; reduction of dry weights of plant organs, leaves, stems, and roots; and inhibition of lateral roots (Parida, Das, and Mittra 2004;Kaya, Erol, and David 2003;Singh et al 2003;Ramoliya and Pandey 2002;Sairam, Rao, and Srivastava 2002;Bolarin et al 2001;Katerji et al 2000;Carvajal et al 1998;Rodriguez et al 1997;Katerji et al 1994;Matsuda and Riazi 1981;Rizk and Normand 1969).…”

“…No entanto, com base nos dados de regressão, notase que a salinidade inibiu menos o crescimento radicular do que o da parte aérea, nas duas épocas analisadas, o que pode ser explicado pela necessidade que tem a planta de garantir uma maior superfície radicular para absorção de água, devido ao abaixamento do potencial osmótico da solução do solo. Alguns autores trabalhando com espécies diferentes, relatam maior sensibilidade da parte aérea em condições de estresse salino: algodoeiro (Meloni et al, 2001) e salvadora (Ramoliya & Pandey, 2002). Outros autores indicam ser mais sensível o sistema radicular: abacaxizeiro (Marinho et al, 1998) et al, 2002), possivelmente devido à constituição genética.…”

Resumo -A expansão da fruticultura no Nordeste brasileiro pode sofrer limitações, já que algumas áreas com elevado potencial de cultivo são abastecidas por água de qualidade insatisfatória. Considerando a potencialidade de cultivo da gravioleira (Annona muricata L.) na região e o fato de não existir dados sobre a produção de mudas enxertadas dessa espécie, sob estresse salino, conduziu-se este trabalho com o objetivo de avaliar os efeitos da salinidade da água de irrigação sobre o tipo 'Crioula' tendo 'Morada' como porta-enxerto. A água de irrigação de condutividade elétrica entre 0,5 e 5,5 dS m -1 foi preparada mantendo-se proporção equivalente a 7:2:1, entre Na:Ca:Mg, respectivamente; o delineamento foi em blocos casualizados, com quatro repetições, 54 plantas por parcela. Foram avaliados: germinação, formação do porta-enxerto (número de folhas, altura de plantas, diâmetro do caule, matéria seca de parte aérea e de raiz, área foliar e número de plantas aptas à enxertia) e número de enxertos vivos. A porcentagem de germinação da gravioleira não foi afetada pelo estresse salino, porém a velocidade de emergência e o acúmulo de fitomassa foram reduzidos com aumento da salinidade da água de irrigação. Pode-se usar água com até 1,5 dS m -1 de condutividade elétrica na formação de mudas de graviola.Termos para indexação: Annona muricata, salinidade, condutividade elétrica, água de irrigação. Germination and formation of grafted seedlings of soursop under saline stressAbstract -The expansion of fruit cultivation in Northeast Brazil may sometimes be restricted because areas of high potential are supplied with poor quality water. Considering the potential of soursop (Annona muricata L.) cultivation in the region and the inexistence of data on grafted seedlings of this specie under saline stress, this study was conducted to evaluate effects of irrigation water salinity on 'Crioula' type as the scion and 'Morada' as the rootstock. The irrigation water with electrical conductivity varying from 0.5 to 5.5 dS m -1 was prepared maintaining the equivalent proportion of 7:2:1 among Na:Ca:Mg, respectively; a completely randomized block design was used, with four replications and 54 plants per plot. The variables appraised were: germination, formation of rootstock (number of leaves, plant height, stem diameter, shoot and root dry matter, leaf area and number of graftable plants) and the number of alive grafts. The percentage of germination was not affected by salinity but the velocity of emergence and accumulation of dry matter reduced with the increase in salinity of irrigation water. In seedling formation, water with salinity up to 1.5 dS m -1 of electrical conductivity may be used.

Stress Responses in Plants

View full text Add to dashboard Cite

In field conditions the plants are most commonly subjected to simultaneous effects of multiple stresses. The mechanisms of plant tolerance to salinity and drought are physiologically connected and overlapping, but some aspects of physiology and metabolism may differ when in the experiment salt and water stress is used separately or both stresses are used simultaneously. Physiological and biochemical reactions of the plants under combined effect of the drought and salinity are unique, which cannot be directly extrapolated from respective responses to each of these stresses individually. Drought and salinity reduce individually the availability of water for plants. However, the presence of salt in the soil inhibits the rate of the development of drought, enabling the plant to survive in unfavorable period of short-term drought without violation of basic physiological functions. At increased NaCl concentration in the soil during the combined stress, basic physiological and biochemical functions of the plants remain constant until a critical threshold, after which the plants' productivity decreases dramatically. This article shows the features of the combined stress and its difference from the drought and salinity individually.
