Physical, Chemical and Biological Properties of some Alternative Growing Substrates.
Peat represented the predominant constituent of growing media for soilless production in the last decades. However, due
to the high cost of extraction and future availability and sustainability, a worldwide search for alternative substrates has been developed,
focusing on secondary processing compounds or recycling wastes. In order to evaluate the suitability of new materials, organic
by-products, namely hemp fiber (2 particle sizes) and grape marc were studied and compared with peat and some rising substitutes: Coir
(3% fiber) and green compost. Methodology: Some of the main physical (particle size distribution, bulk density, water holding capacity
and air capacity), chemical (pH, electrical conductivity, ash, carbon, hydrogen, nitrogen and heavy metals content) and biological
properties (phytotoxicity) were analyzed. Results: All materials showed water holding capacity >40% (threshold considered sufficient
on the base of peat-related classification), except for coir and hemp with large particle size and marc that registered a poor water-holding
capacity (<40% retained water). The pH of the base materials was different with values ranging between 6.21 and 9.05. Compost and marc
showed high values of electrical conductivity and copper content (and heavy metals for green compost) and a possible negative influence
on germination of cress as resulting from the bioassay. Conclusion: Physical, chemical and biological properties of the materials suggested
that coir has the potential to partially or totally replace peat, whereas marc and compost require to be mixed with other materials or
properly select the source-of-origin materials before processing
Reproductive patterns of 1-year-old mixed shoots in different olive cultivars in Central Italy.
The increase of plant density in new olive orchard systems requires a deeper
investigation about plant architecture to understand growth, branching pattern and
yield and to select most suitable cultivars. The spatial arrangement of vegetative and
reproductive structures helps to explain the fruiting attitude of the plant at different
levels: the whole tree, the productive branch and the fruiting shoot. The objective of
the present study was to investigate the reproductive attitude of 1-year-old mixed
shoots in six olive cultivars grown in central Italy in order to determine inflorescence
and fruit distribution and identify correlations between vegetative-reproductive
variables. Results showed a differing inflorescence and fruit distribution along the
shoot axis: a higher number in the median-distal portion for the cultivars ‘Arbequina’,
‘Don Carlo’ and ‘Giulia’, in the median-basal portion for ‘FS17’ and more homogeneous
for ‘Arbosana’ and ‘Koroneiki’. A higher fruit number with increasing length of 1-yearold
mixed shoot was registered, but with a shallow slope relationship compared to the
number of flowers per shoot. After fruit set, the crop load remained constant until
harvest. Cultivars showed a different vegetative-reproductive pattern in the climatic
conditions of central Italy with differences between all cultivars. This study
contributes to understand the reproductive pattern of 1-year-old mixed shoot in olive,
suggesting a different suitability of the cultivars to different planting density systems
