TAILIEUCHUNG - Combination of low oxygen and high carbon dioxide treatments alters sprouting of white asparagus

Our results suggest that controlling atmospheric O2 and CO2 concentrations around the rootstock during storage could be a new, effective method to alter the harvest period of white asparagus, including cultivation of fresh asparagus in a single cropping system with forcing culture. | Turkish Journal of Agriculture and Forestry Turk J Agric For (2016) 40: 450-455 © TÜBİTAK doi: Research Article Combination of low oxygen and high carbon dioxide treatments alters sprouting of white asparagus 1, 1 1 2 Hiroaki KITAZAWA *, Naoko HASEGAWA , Masayasu NAGATA , Machiko FUKUDA , 3 4 2 Shin-ichi WATANABE , Atsushi YAMASAKI , Atsuko URAGAMI 1 Food Engineering Division, National Food Research Institute, NARO, Tsukuba, Japan 2 Vegetable Production Technology Division, NARO Institute of Vegetable and Tea Science, Tsukuba, Japan 3 Horticulture Research Division, NARO Kyushu Okinawa Agricultural Research Center, Kurume, Japan 4 Field Crop and Horticulture Research Division, NARO Tohoku Agricultural Research Center, Morioka, Japan Received: Accepted/Published Online: Final Version: Abstract: A single cropping system with 1-year-old rootstocks by forcing culture has been proposed for white asparagus (Asparagus officinalis) production in Japan. To develop a method to control the sprouting period for such a cropping system, we investigated the effects of low oxygen (O2), high carbon dioxide (CO2), and a combination of these on the sprouting of asparagus spears, using a laboratory-scale test. We stored the rootstocks without soil for 6 weeks in six treatment conditions (20% O2, control; 20% O2 + 8% CO2; 20% O2 + 16% CO2; 8% O2; 8% O2 + 8% CO2; and 8% O2 + 16% CO2). After storage, we planted the rootstocks in pots with soil and investigated their yield performance for 20 weeks. Only the 8% O2 + 16% CO2 treatment applied during rootstock storage suppressed the sprouting of spears. The number of harvested spears and the yield of spears per plant in the 8% O2 + 16% CO2 treatment was higher than in control at the 16–20-week period, although the weight per spear did not differ. We suggest that the extension of sprouting after planting was due to the suppression of .
