“…In leaf gas exchange, the most common effect of flooding stress is a reduction in leaf transpiration and stomatal closure (Blanke and Cooke, 2004;Yetisir et al, 2006;Atkinson et al, 2008;Bai et al, 2013). In avocado trees (Persea americana Mill.…”

Agriculture is severely impacted by water stress due either to excess (hypoxia/anoxia) or deficit of water availability. Hypoxia/anoxia is associated with oxygen (O 2 ) deficiency or depletion, inducing several anatomical, morphological, physiological, and molecular changes. The majority of these alterations are adaptive mechanisms to cope with low O 2 availability; among them, alterations in shoot length, aerenchyma formation and adventitious roots have been described in several studies. The aim of this review was to address the association between abscisic acid (ABA) and ethylene in function of water availability in plants. The major physiological responses to low O 2 are associated with changes in root respiration, stomatal conductance, photosynthesis, and fermentation pathways in roots. In addition, several changes in gene expression have been associated with pathways that are not present under normal O 2 supply. The expression of ethylene receptor genes is up-regulated by low O 2 , and ethylene seems to have a crucial role in anatomical and physiological effects during hypoxia/anoxia. During O 2 depletion, ethylene accumulation down-regulates ABA by inhibiting rate-limiting enzymes in ABA biosynthesis and by activating ABA breakdown to phaseic acid. With regard to water deficit, drought is primarily sensed by the roots, inducing a signal cascade to the shoots via xylem causing physiological and morphological changes. Several genes are regulated up or down with osmotic stress; the majority of these responsive genes can be driven by either an ABA-dependent or ABA-independent pathway. Some studies suggest that ethylene shuts down leaf growth very fast after the plant senses limited water availability. Ethylene accumulation can antagonize the control of gas exchange and leaf growth upon drought and ABA accumulation.

“…For decades, the rootstock has been used to provide resistance to plants against rising and falling temperatures (Rivero et al, 2003;Venema et al, 2008), is a good tool used to facilitate the ansortion of available mineral nutrient of the soil solution (Leonardi and Giuffrida, 2006), increase levels and synthesis of hormones (Dong et al, 2008), strengthens the crops so that they are able to develop in salinity conditions (Colla et al, 2010), improves the processes of the plant that help to make the use of water more efficient (Rouphael et al, 2008a), decrease uptake of persistent organic pollutant (COPs) or toxic chemical resistant compounds from cultivable soils (Otani and Seike, 2007), helps tolerate overwatering and waterlogging (Yetisir et al, 2006), improves the caracteristics of the fruit that give it greater commercial value (Proietti et al, 2008), and minimize the toxic effects as a result of high concentrations of copper, cadmium and boron (Savvas et al, 2009;Arao et al, 2008). Nevertheless, there is little published scientific information worldwide about the efficiency of nitrogen in crops that have been grafted (Djidonou et al, 2013;Du et al, 2016).…”

Nitrogen Use Efficiency and Yield in Response Graft Bell Pepper Cultivars

The aim of the current study was to evaluate the performance of nitrogen (N) efficient use by ‘Fascinato’ (F), ‘Jannette’ (J), ‘Orangela’ (O), and ‘Sweet’ (S) cultivars grafted onto ‘Terrano’ (T) and ‘Robusto’ (R) rootstocks. Such evaluation was achieved by analyses of physiological and biochemical variables involved in N metabolism between grafted and ungrafted plants. Our findings point out that grafted ‘Fascinato’ cultivar (F/T) registered greatest relative leaf chlorophyll content, total chlorophyll concentration, a higher NR activity than did graft ‘Janette’ cultivar (J/T). In addition, these results reveal high significance with the interaction variety*date for these variables (relative leaf Chl, total Chl and NR activity), during the months of fruit yield of grafted bell pepper cultivars. This situation suggest than the effect of grafting under the increased of crop yield depend on the type of variety, as resulted with grafted ‘Fascinato’ cultivar.

“…In both cases soils with high clay content and/or compaction due to agricultural practices are susceptible to soil waterlogging. These effects contribute to limiting water and air movement in the soil, generating oxygen (O 2 ) deficiency and carbon dioxide (CO 2 ) accumulation (Kozlowski, 1997;Núñez-Elisea et al, 1999;Jackson and Colmer, 2005;Yetisir et al, 2006) as well as changes in the soils chemical properties (Unger and Kaspar, 1994). The gas exchange between soil and atmosphere in a wellaerated soil is sufficiently rapid to impede O 2 deficiency and toxicity due to CO 2 excess or other gases.…”

Under transient waterlogging, a number of transformations in the soil are generated associated with lack of aeration, seriously affecting the root system. Significant progress has been reported on understanding the effects of lack of oxygen on the metabolism of the roots, although few studies have examined changes in the soil. Diverging conclusions about the degree of tolerance exhibited by plants exclude the effects of hypoxia and anoxia on physical-chemical soil properties under plant experiments. This review examines the main changes occurring in soil and roots due to transient soil waterlogging conditions. Parameters such as antioxidant capacity, nutrient uptake dynamics and regeneration and distribution of the root system are relevant for selecting rootstocks tolerant to soil waterlogging.
