“…When the experiment was conducted in the fall, the lowering of the osmotic potential in these species was much less than occurred during the summer. As confirmed by other authors (Niu et al, 2007a;Zollinger et al, 2005), results highlighted how environmental conditions could influence the response to salt stress: the higher temperature and irradiance typical of summer meant that plants became more stressed than in the fall, when all the species, except A. cana, maintained an acceptable visual quality. Species like S. coccinea, A. millefolium and G. aristata were considered highly salt tolerant, because they could be irrigated with a saline solution up to 4 dS m -1 under both summer and fall conditions, with little or no growth reduction.…”

“…L. angustifolia began to show leaf injury about 4 weeks after the start of saline irrigation, and died in the subsequent weeks at 6.4 and 12 dS m -1 . However, the importance of the nature of the salts present is illustrated by the results of Zollinger et al (2005), who reported that L. angustifolia survived at 8.3 dS m -1 when NaCl and CaCl 2 (2:1 molar ratio) were used for saline solution.…”

“…The same results were found for Nerium oleander grown in a pot and submitted to low water availability, which during the stress period exhibited symptoms of deficiency, but after the restricted water deficit, the plants returned to normal appearance (LENZI et al, 2009). The same may be said for other ornamental species such as Gallardia aristada and Leucanthemum x superbum that resumed their growth when watered once more (ZOLLINGER et al, 2006).…”

“…Increase in water deficit in the leaves of I. cairica during the period of stress proves this characteristic of drought tolerance. These characteristics are also present in other ornamental species considered resistant to drought periods, such as Penstemon barbatus, Penstemon x mexicali and Lavandula angustifolia (ZOLLINGER et al, 2006), and which are recommended for use in landscaping.…”

Green spaces require frequent watering, increasing the pressure on water resources. The use of native plants in landscaping reduces the risks of biological contamination, contributing to preservation of Brazilian biodiversity and provides the value of sustainability in urban green areas. Of these native plants, a restricted number are native lianas which are adapted to Brazilian climate and available on the market. In this regard, the selection and recommending of native plants which are efficient in use of water for planting in urban areas constitute an effective strategy for conservation of water resources. Thus, the purpose of this study was to evaluate the growth and development of I. cairica plants submitted to water deficit. For a period of 100 days after transplanting, plants of this species were grown with watered at pot capacity except for 30 days (from the 30 th to the 60 th day) when four water deficits (25, 50, 75 and 100% pot capacity) were applied. During all regimes of water deficiency applied, there was a 100% survival rate. After reestablishment of water regime the species recovered its growth, even that was submitted to the 25% of pot capacity. It testify that I. cairica is resistant to low water availability. Index terms:Morning glory, climbing plants, water stress, landscaping. RESUMOOs espaços verdes necessitam de irrigações freqüentes, aumentando a pressão sobre os recursos hídricos. A utilização de plantas nativas em paisagismo diminui os riscos de contaminação biológica, contribui para a preservação da biodiversidade brasileira e propicia a sua valorização sustentável em áreas verdes. Destas, um número restrito são de lianas nativas aclimatadas e disponíveis no mercado. Nesse sentido, a seleção e indicação de plantas nativas eficientes no uso da água para implantação em paisagismo constituem-se uma estratégia eficaz na conservação dos recursos hídricos. Assim, buscou-se avaliar o crescimento e desenvolvimento de plantas de Ipomoea cairica submetidas a déficit hídrico. Ao longo de 100 dias após o transplante, plantas dessa espécie foram cultivadas com irrigação em capacidade de vaso, exceto por 30 dias (do 31º ao 60º dia) quando se aplicou quatro regimes hídricos (25, 50, 75 e 100% de capacidade de vaso). Durante o período de deficiência hídrica, houve 100% de sobrevivência, em todos os regimes hídricos aplicados. Após o restabelecimento hídrico, a espécie retomou seu crescimento, mesmo a que foi submetida a 25% da capacidade de vaso. Isto prova que I. cairica é resistente a baixa disponibilidade hídrica.Termos para indexação: Ipoméia, trepadeiras, estresse hídrico, paisagismo.

“…This mechanism allows the plant to explore more soil volume to absorb water from deeper layers that are not afected by less developed roots. However, no relationship has been demonstrated between root/stem ratio and water deicit tolerance [19]. In addition, length or root density may have a direct relationship to this tolerance [20].…”

Alfalfa (Medicago sativa L.) is one of the most cultivated forage legumes in Morocco thanks to its great adaptation to the climatic conditions of this country, its high protein content and its ability to ix atmospheric nitrogen in symbiosis with rhizobia. Environmental stresses such as drought and salinity constitute a major factor limiting the symbiotic nitrogen ixation and legume productivity. In the last decades, this process has interested scholars in understanding the implication of these strains in legume stress tolerance in order to make these symbioses more eicient under diicult conditions. Seed osmopriming is a great technique in the amelioration of seed germination and seedlings growth in responses to several abiotic stress conditions. In this chapter, the efects of water deicit on the Moroccan alfalfa populations and their symbiotic association with rhizobia were discussed. Besides, osmopriming could make these symbioses more eicient especially under stress conditions.
