“…These authors stated that floral analysis could be used to determine the nutritional status of crops at an early stage, since the mineral composition of flowers at full bloom is often related to the nutrient content (of the same nutrients) in leaves taken 120 days later. Flower analysis has now been developed for a number of fruit trees: pear Sanz and Montañés, 1995b;Sanz et al, 1994), peach (Belkhodja et al, 1998b;Igartua et al, 2000;Sanz et al, 1997a;Sanz and Montañés, 1995b), nectarine (Toselli et al, 2000), apple (Morales et al, 1998c;Sanz et al, 1998), walnut (Drossopoulos et al, 1996), olive (Bouranis et al, 1999), pistachio (Vemmos, 1999), almond (Bouranis et al, 2001), and citrus (Pestana et al, 2001b).…”

“…Iron is very abundant in most soils, and its availability to plants is only low in higher pH soils. Iron chlorosis occurs frequently in fruit trees such as peach (Igartua et al 2000), pear (Sanz et al 1994), and citrus (Pestana et al 2001). Affected leaves turn yellow while the leaf veins remain green.…”

Arbuscular mycorrhizal enhancement of iron concentration by Poncirus trifoliata L. Raf and Citrus reticulata Blanco grown on sand medium under different pH

The effect of the arbuscular mycorrhizal (AM) fungus (Glomus versiforme) on iron contents by two citrus rootstocks (trifoliate orange [Poncirus trifoliata L. Raf] and red tangerine [Citrus reticulata Blanco]) was studied in sand culture under different pH conditions. Seeds were sown in a mixed substrate (perlite/sand, 1:1 [v/v]) inoculated with or without mycorrhizal inoculum. The experiment was carried out at four pH levels by applying nutrient solution at pH 5.0, 6.0, 7.0, or 8.0 to P. trifoliata and pH 5.2, 6.2, 7.2, or 8.2 to C. reticulata. No AM colonization was found in uninoculated control (NM) and plants, and root colonization in AM plants was depressed under iron deficiency at high pH. Colonization by G. versiforme led to higher dry weights of shoots compared with NM treatments, suggesting that G. versiforme enhanced plant growth. Higher concentration of chlorophyll and active iron, lower ratios of P/Fe and 50(10P+K)/Fe were present in AM plants than NM treatments. Nevertheless, G. versiforme improved root Fe (III) chelate reductase activity of P. trifoliata and C. reticulata. The data indicate that plant uptake and translocation of iron were enhanced and AM fungi may be considered as a potential tool for bioremediation of citrus iron deficiency.

“…However, leaf analysis poses some drawbacks such as dilution effects and new approaches, like flower analysis, have been developed for highly profitable crops, namely almond (Bouranis et al, 2001), cherry (Jiménez et al, 2004), orange (Pestana et al, 2001), peach (Igartua et al, 2000;Sanz and Montañés, 1995), and pear (Sanz et al, 1994).…”

“…Since the mineral composition of flowers at full bloom is often related to the nutrient concentration in leaves taken later in the season, Sanz et al (1993) proposed methods based on the mineral composition of flowers to determine the nutritional status of crops at an early stage. Since then, flower analysis has been developed for many deciduous fruit trees, such as almond (Bouranis et al, 2001), cherry (Jiménez et al, 2004), orange (Pestana et al, 2001), peach (Igartua et al, 2000;Sanz and Montañés, 1995), and pear (Sanz et al, 1994).…”

The mineral concentration of flowers and the seasonal fluctuation of macro-[nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), and magnesium (Mg)] and micronutrients [iron (Fe), manganese (Mn), zinc (Zn), and copper (Cu)] in leaves of male, female, and hermaphroditic carob trees (Ceratonia siliqua L.) were studied. The nutrient dynamics were linked not only to phenological events, but also to the gender of the trees. The females were able to allocate more nutrients to leaves than male trees, even though male flowers were richer in particular elements such as N and Zn. The hermaphrodites supported the development of both inflorescences and fruits with a lower seasonal variation and a lower leaf nutrient concentration, as compared to the other genders, which may indicate a more efficient use of resources. Flowers had, in general, a higher concentration of N, P, and K, and a lower Mn concentration than in leaves. Flowers of the females had a lower nutrient concentration compared to males or hermaphrodites.
