In this study, we hve ompred fruit qulity, udrek rte nd florl ud s ffeted y windreks. And lso we surveyed severl mirolimte indies of kiwifruit orhrd depending on the overing mterils of rh-type windreks. METHODS AND RESULTS: Five different windrek mterils inluding polyethylene film (PE), lue- nd white-olored nets were tested in pipe-frmed rhtype kiwifruit vineyrds s the overing mterils. Photosynthetilly tive rdition (PAR), nnul men temperture (AMT) nd hill unit (CU) s well s fruit qulity were ompred mong the overing mterils. In -2 ll tretments, nnul PAR ws more thn 400 μmol m s -1, in whih kiwifruit lef ould reh its mximum photosynthesis, sine the leves were emerged. Annul men temperture ws greter in 0.1 mm-pe overing s muh s 1 2 thn other windreks. In CU lulted y three different models, ll windreks showed more *Corresponding uthor: Yong Bok Lee Phone: +82-55-772-1967; Fx: +82-55-772-1969; E-mil: ylee@gnu..kr thn 1400 CU tht is fully fulfilled CU for kiwifruit rest ompletion. There were no differene in udrek rte mong the overing mterils. Fruit weight ws hevier in 0.1 mm-pe nd white-net (4 mm) thn other windreks. CONCLUSION: Regrdless of the windrek mterils, the PAR quntity ws enough for kiwifruit photosynthesis. AndCUforkiwifruitrestompletionwsfullyhievedin ll tretments. However, with respet to fruit weight, quntity of PAR, nd AMT, et., It is highly reommended for kiwifruit growers to hoose 0.1 mm-pe nd white-net (4 mm) s for their windreks mterils.
