Abstract
Nowadays, nets play an irreplaceable role in the production of many fruit species due to the extreme weather conditions caused by climate changes and the high-quality demands of consumers.
Not so long ago, a new technology emerged, namely photoselective and anti-insect nets.
In addition to providing basic protection (from hail, wind, excessive solar radiation, etc.), photoselective nets allow spectral manipulation of transmitted light, thus promoting the desired photomorphogenic responses of plants, while anti-insect nets provide protection against certain pests by creating mechanical barrier.
The main objective of this study was therefore to determine whether red and white photoselective anti-insect nets (mesh size 2.4×4.8 mm) differ in their effect on vegetative, generative traits and bioactive properties of peach ´Suncrest´. The study was conducted in a peach orchard in Vratiinec, northern Croatia.
Data were analysed using the T-test in SAS Ver. 9.4 statistical software (SAS Institute, NC). Statistically, significant differences were obtained for the following traits: leaf petiole length, fruit weight, width, radius, and volume, L*, a*, b*, C* and h° fruit ground colour parameters and a/b, CCL, COL, CIRG1 and CIRG2 fruit ground colour indexes and for total fruit polyphenol content.
For the other vegetative (trunk cross-sectional area, length, internode length, thickness and density of internodes of the one-year shoot, as well as leaf blade length, width, surface and shape index), morphological (fruit length, shape index and endocarp weight), productive (yield, yield efficiency, fruit flesh ratio and density, share of decayed fruit), basic quality (L*, a*, b*, C* and h° fruit additional colour parameters and a/b, CCL, COL, CIRG1 and CIRG2 fruit additional colour indexes, fruit firmness, total soluble solids, titratable acidity and total soluble solids/titratable acidity ratio) traits and bioactive properties (fruit antioxidant potential ABTS and DPPH, β-carotene content and total anthocyanin content) no significant differences were obtained.
