There is a general trend of biodiversity loss at global, regional, national and local levels. To monitor this trend, international policy processes have created a wealth of indicators over the last two decades. However, genetic diversity indicators are regrettably absent from comprehensive bio-monitoring schemes.
Here, we provide a review and an assessment of the different attempts made to provide such indicators for tree genetic diversity from the global level down to the level of the management unit. So far, no generally accepted indicators have been provided as international standards, nor tested for their possible use in practice. We suggest that indicators for monitoring genetic diversity and dynamics should be based on ecological and demographic surrogates of adaptive diversity as well as genetic markers capable of identifying genetic erosion and gene flow. A comparison of past and present genecological distributions (patterns of genetic variation of key adaptive traits in the ecological space) of selected species is a realistic way of assessing the trend of intra-specific variation, and thus provides a state indicator of tree genetic diversity also able to reflect possible pressures threatening genetic diversity. Revealing benefits of genetic diversity related to ecosystem services is complex, but current trends in plantation performance offer the possibility of an indicator of benefit. Response indicators are generally much easier to define, because recognition
and even quantification of, e.g., research, education, breeding, conservation, and regulation actions and programs are relatively straightforward. Only state indicators can reveal genetic patterns and processes, which are fundamental for maintaining genetic diversity. Indirect indicators of pressure, benefit, or response should therefore not be used independently of state indicators. A coherent set of indicators covering diversity?productivity?knowledge?management based on the genecological approach is proposed for application on appropriate groups of tree species in the wild and in cultivation worldwide.
These indicators realistically reflect the state, trends and potentials of the world?s tree genetic resources to support sustainable growth. The state of the genetic iversity will be based on trends in population distributions and diversity patterns for selected species. The productivity of the genetic resource of trees in current use will reflect the possible potential of mobilizing the resource further. Trends in knowledge will underpin the potential capacity for development of the resource and current anagement of the genetic resource itself will reveal how well we are actually doing and where improvements are required.

ABSTRACT.
Fertilizers application in irrigation water (Fertigation) is considered to be an efficient method of fertilizing fruit trees, but some information is needed on the relationship between irrigation depth and nitrogen (N). The objective of this work was to know the response of apple tree to different levels of irrigation depth based on maximum crop evapotranspiration (ET c) and N fertilization. The experiment was carried out in 2008-09 summer growing season of apple trees Malus x domestica Borkh 'Gala', with a row spacing of 4×1 m (2500 pl. ha -1), seven years old, on the M9 rootstock, in a silt loam soil. The experimental design was split plots with two factors, with four complete randomized blocks. A main plot was irrigation depth according ET c: 0% (only rainfall), 50, 75 and 100% of the ET c, and a submain plot was three N fertilization levels: 0, 110 and 220 kg N ha -1. Soil water content (0-20 cm of soil depth), leaf minerals content (N, P, K, Ca, Mg), trunk section diameter, fruit total number, fruit diameter, weight, colour and firmness were measured. Different leaf mineral contents for N, K and P according irrigation depth were observed at pre-harvest. Nitrogen fertilization, however, only affected the leaf N content. Results indicate that it was a significant differences in yield, fruit diameter and weight response to the supplemental irrigation application. Yield for irrigation at 100% ET c, reached 40 t ha -1 and, for non-irrigation plants 27 t ha -1. Fruit diameters average was 71.53 and 62.69 mm for 100% ET c and non-irrigation treatments, respectively; and there were 70.97 and 67.88 mm for 220 kg N ha -1 and non-nitrogen treatments respectively. The differences in N fertilization on yield and fruit quality variables were not observed. Nitrogen application rates only affected fruit diameter but not yield. MenosABSTRACT.
