The poor growth and chlorosis suffered by lupins when grown on fine-textured alkaline soils appears primarily related to Fe deficiency which is affected by the level of HCO3-; and CaCO3 in the soil.Plants of Lupinus angustifolius were grown on an alkaline, sandy clay loam which was either acidified or limed. Additionally, plants received either adequate water (field capacity) or excess water to adjust the aeration of the soil.Plant growth was closely related to the concentration of Fe within the young leaves. Liming the soil or watering above field capacity reduced the Fe concentrations in shoots, induced chlorosis and reduced growth. Chlorosis and reduced growth was not caused by Mn deficiency, even though treatments that reduced growth also reduced Mn concentrations in shoots.The lime chlorosis disorder in lupins therefore is primarily caused by an inability of the plants to obtain Fe in calcareous soils and not caused by Mn deficiency or by inactivation of Fe within the shoots.

Variation exists between lupins and peas and between species of lupins in their performance on fine-textured alkaline soils. Two species of lupins (Lupinus angustifolus, L. cosentinii) and peas (Pisum sativum) were grown on a fine-textured alkaline soil under conditions conducive to Fe deficiency to determine whether differences between species could be related to susceptibility to Fe deficiency.Treatments induced severe Fe deficiency and markedly reduced growth of L. angustifolius, had only a moderate effect on L. cosentinii, and had no effect on P. sativum. Poor growth and symptoms were closely related to Fe concentrations within the leaves of plants.Lupins and peas therefore vary markedly in their tolerance to Fe deficiency, which is possibly related to their ability to produce reactions around their roots which make Fe available for uptake.

Lupins differ in their efficiency to utilize Fe3+ in soils containing CaCO3. Most lupin species are susceptible to Fe deficiency. The objective of this study was to screen different lupin species, including introduced cultivars and wild types collected in Israel, for susceptibility to Fe deficiency. In a greenhouse experiment, inoculated seedlings, 7 to 10 days old, were planted in 1 L pots filled with a mountain rendzina soil from Emek Haela (pH=7.3, CaCO3- 45%), or with a brown-red sandy-loam soil from Rehovot (pH=7.7) not containing CaCO3. On the calcareous soil, susceptible lupin plants from day 7 onward showed various degrees of chlorosis, suggesting Fe deficiency, which at a later stage caused reduction of growth, necrosis of the leaf tissue, leaf abscission and ultimately death of the plants. Soil application of FeEDDHA resulted in an immediate remedy of the deficiency symptoms. No deficiency symptoms were observed on plants growing on the sandy-loam soil lacking CaCO3. Ranking of lupins based on visual symptoms of Fe deficiency and on chlorophyll concentration of young leaves relative to their tolerance to soil lime was as follows (location of source plants in brackets). Very good: Lupinus pilosw (Emek Haela), L. cosentinii cv. Erregulla and L. angustifolfus cv. Yorrel. Moderate L. angustifolius cv. Illyarrie. Low L. palaestinus (Gesher Haziv), L. albus cv. L221, L. angustifolius (Gesher Haziv). Very low: L. angustifolius (Givat Brenner), L. palaestinus (Rehovot). The need for further exploration of wild lime-resistant genotypes is emphasized.

Relationships diagnostic of manganese (Mn) deficiency in Lupinus angustifolius were examined in growth chamber experiments by studying the effects of Mn supply on plant growth and on photosynthesis and Mn concentrations in young leaves and whole shoots. A critical Mn concentration in youngest fully expanded leaves (YFEL) of 30 8g/g dry matter was found to be diagnostic of reduced dry matter production. A similar critical concentration was found for whole shoots, and the criteria were consistent over a wide range of ontogeny until at least early flowering. A less sensitive criterion of Mn deficiency was that for chlorophyll 'a' fluorescence characteristics of YFEL's (17 8g/g in YFEL), which estimates photosynthetic dysfunction in relation to Mn supply. The distal segments of lupin leaves best reflected changes in fluorescence in relation to their Mn status. The prognosis of impending Mn deficiency in maturing lupin plants was also examined in field and growth chamber experiments by studying the effects of Mn supply on the relationships between the concentrations of Mn in plant components at anthesis, and the subsequent appearance of Mn deficient ('split') seed on maturing plants. The absence of Mn deficient seed in main axis and first-order lateral inflorescences of maturing lupins could be predicted by Mn concentrations in stems at anthesis of >20 8g/g. Manganese concentrations of buds, leaves and tissues containing a high proportion of leaf, were found to be poor predictors of subsequent Mn deficiency in maturing lupins.

Several fruit trees are able to cope with iron (Fe) deficiency when grown in calcareous soils in the Mediterranean region, although information regarding well adapted slow-growing species is scarce, and the mechanisms activated by these species are not described in the literature. A crucial issue related to tolerance is the need to transport Fe over relatively long distances inside the plant. To evaluate the possible role of organic acids in the movement of Fe in tolerant plants, we studied the concentration of low molecular weight organic acids in several organs of 1-year old carob plants grown for 55 days in nutrient solutions without Fe (0 µM Fe) or with 1 µM Fe and 10 µM Fe. Roots, stems and leaves were harvested, and the biomass, Fe and organic acid contents quantified. Total leaf chlorophyll (Chl) was evaluated in young leaves over the experimental period and the activity of root ferric chelate-reductase (FC-R; EC 1.16.1.17) was determined after 35 days, when deficiency symptoms appeared. Iron chlorosis was observed only at the end of the experiment in plants grown in the absence of Fe, and these plants had a smaller DW of leaves and also significant greater activity of root FC-R. Iron deficiency (Fe0 and Fe1 treatments) induced significant changes in the concentrations of succinic, malic, citric and fumaric acids, which increased in roots, or in basal, middle and apical leaves. There were significant correlations between most organic acids (with the exceptions of 2-oxoglutaric and tartaric acids) and leaf Chl. Analysis of each type of leaf showed that more succinic and malic acids were present in young chlorotic leaves while the reverse was true for quinic acid. These changes in organic acids followed a root-to-foliage pathway that was similar in all leaf types and particularly evident in young chlorotic leaves. We hypothesised that it was associated with Fe transport from roots to aboveground tissues, as there were significant differences in Fe contents between treatments with and without Fe.

Major Factors

Soil type is an important factor affecting the growth of lupins. Successful lupin cultivation is generally restricted to deep, acid to neutral, coarse-textured soils. Very little is known about the factors affecting the performance of lupins on other soil types. This review attempts to define the major factors controlling the growth of lupins of fine-textured, alkaline soils, with a view to providing a focus for future research. Wild populations of the genus, as a whole, occupy soils of a wide pH and textural range (pH 4-8.5, texture ranging from coarse sands to fine clays), although the majority of populations are found on light soils of sandy loam or loamy sand texture with pH values between 5.5 and 7. Species within the genus have distinct preferences for soils of a narrower range than the genus as a whole. Commercially cultivated species appear to be adapted to a narrower range of soil types than the wild species. Iron nutrition, seedling emergence, and rooting pattern and phenology are the major factors influencing the performance of lupins on fine-textured, alkaline soils. Lupins appear to possess some mechanisms thought to enhance the availability of Fe, nevertheless they suffer severely from Fe deficiency. Conditions prevailing on fine-textured, alkaline soils (poor drainage and aeration, CaCO3) are frequently conducive to Fe deficiency. The epigeal pattern of emergence of lupins is unsuitable to fine-textured soils, particularly if crust formation occurs. The rooting pattern and phenology of lupins is better suited to deep sandy soils than shallow, fine-textured soils, and this exacerbates late-season water stress. A better understanding of these factors may allow breeding and management strategies to be developed which will extend lupin cultivation to a wider range of soils.

Abstract A description is provided for Xanthomonas campestris pv. graminis. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Lolium italicum, L. multiflorum, L. perenne, Dactylis glomerata, Festuca pratensis, and Trisetum flavescens. Single cases of natural infection of Agropyron repens, Phalaris arundinacea and Phleum pratense are also recorded (62, 241), but their status in the natural host range is unknown. In inoculation tests (Egli et al., 1975; Egli & Schmidt, 1982) the following were highly susceptible: Alopecurus pratensis, Dactylis glomerata, Festuca arundinacea, F. pratensis, F. rubra, Lolium loliaceum, L. multiforum, L. parabolicae, L. perenne, L. remotum, L. temulentum, Phleum arenarium and P. bertolonii. Showing much less susceptibility were Agrostis alba, Arrhenatherum elatius, Phleum alpinum, P. phleoides, P. pratense, Poa annua, P. compressa, P. fertilis, P. memoralis, P. pratensis and P. trivialis. Leyns et al. (61, 6162) found that Agrosas tenuis and Festuca ovina were moderately susceptible when inoculated. Egli et al. (1975) recorded doubtful symptoms on Hordeum vulgare and Triacum aestivam on inoculation, but consider that they are unlikely to be naturally infected. DISEASE: Bacterial wilt of forage grasses. Symptoms usually first noticed at the heading stage, when young leaves curl and wither, and shoots remain stunted or may die. Other plants will continue to make poor growth and produce small, distorted inflorescences. Chlorotic and necrotic zones form on the older leaves along long stretches of vascular bundles, often extending into the sheaths. Bacterial streaming may be seen under the microscope from the cut ends of vascular bundles of infected tissue mounted in water. GEOGRAPHICAL DISTRIBUTION: CMI Map 533, ed. 1, 1979 lists France, Germany, Switzerland and Wales, to which must be added Scotland (63, 2925), Belgium (61, 4199), Netherlands, Norway (62, 241), and New Zealand (62, 241). Possibly in USA (IL; 61, 5045) though this disease is currently attributed to a Rickettsia- like organism. TRANSMISSION: Within the crop transmission is presumed to be by the blades of mowing machines.

Continuous irrigation of soils with untreated effluents can result in the accumulation and translocation of some metals in the soils and plants. Application of farmyard manure (FYM) to such soils may increase or decrease their availability and retention time. Calcareous soils contaminated with 100, 200, and 400mg kg–1 Ni, Zn, and Pb as chloride salts were used, and farmyard manure added (40g kg–1 for 90 days) with moisture contents at field capacity. Soil samples were drawn at 30 day intervals, and metals extracted with (AB-DTPA) C14H23NO3O10. With FYM application of 400 mg kg–1, Ni availability increased from 179 (day 30) to 240 mg kg–1(day 90); Zn from 163 (day 30) to 230 mg kg–1 (day 90), but, Pb decreased from 214 to 161 mg kg–1. FYM forms multi-dentate complex which greatly enhances the Ni and Zn solubility, and organic matter immobilizes Pb in the soil.

The Impact

Lime-induced chlorosis (LIC) is an important abiotic constraint affecting the growth and yield of grapevines growing in calcareous soils in the Mediterranean region, and the sensory properties of the produced wine. In the work presented herein, the impact of LIC on the nutritional status and chlorophyll content was assessed for eleven varieties and a clone (Merlot, Pinot Noir, Cabernet Sauvignon, Tempranillo, Parraleta, Moristel, Aglianico, Macabeo, Sauvignon, Chardonnay, and Riesling), grafted to the same rootstock (1103 Paulsen). Macro- and micronutrient contents were determined in the fruit set and veraison stages by petiole analyses, while chlorophyll content in young leaves was monitored by SPAD. Significant differences were detected amongst varieties for all nutrients (including Fe), and inverse relationships between Fe and P contents in the petiole and chlorophyll concentration in the young leaves were found. Regarding LIC resistance, the Fe and chlorophyll contents suggest that Cabernet Sauvignon, Tempranillo and Aglianico varieties would show the best performance, while Sauvignon would be the least tolerant.

Potato Growth

The enhancement of the actual low yields is the most important challenge regarding organic farming management. In this view, a valid tool may arise by the improvement of fertilization management and efficiency. In this regard, arbuscular mycorrhizal fungi (AMF) can play an important role, especially in low fertility soils such as calcareous ones, through a better nutrient uptake and by alleviating abiotic stresses. A replicated-space experiment was carried out to investigate the role of mycorrhizal-based inoculants combined with full or halved fertilizer doses on yield and physiological traits of three early potato cultivars organically grown in highly calcareous and alkaline soils. The results indicate that AMF symbiosis ameliorated, in comparison to the not-inoculated plants, the potato tolerance to limestone stress by enhancing the potential quantum efficiency of photosystem II (Fv/F0) and plant gas-exchange parameters (photosynthesis rate and stomatal conductance). Moreover, a significant improvement of marketable yield (+25%) was observed, mainly due to an increase of the number of tubers plant−1 (+21%) and, to a lesser extent, of average tuber weight (+10%). The AMF efficiency was higher applying halved fertilizer doses and in the location where soil conditions were unfavourable for potato growth. Moreover, the qRT-PCR highlighted that AMF colonization was similar in each location, demonstrating their tolerance to limestone, alkalinity and P stresses. These findings outlined that AMF are good candidate to bio-ameliorate calcareous soils and are very useful for improving potato yields under organic farming, limiting external fertilizers supply and environmental pollution.
