Abstract:

As a non-conventional biodiesel feedstock, false linseed [Camelina sativa (L.) Crantz] was investigated in a three-year field experiment testing the effects of two sowing times [winter (W) and spring (S)] and two plant densities [250,000 (D1) and 500,000 plants ha-1 (D2)] in the rainfed conditions of Southern Europe (Central Italy) aiming to find the oil optimal production conditions. The W sown crops showed a weak cold tolerance with a plant mortality of about 70% and a greater branching capacity, offsetting partially the yield losses. Seed yield varied from 0.67 to 1.32 t ha-1 (respectively in W D1 and S D2 as two year-average) and it was significantly lower in the W than in the S sown crops (0.64 vs 1.1 t ha-1). The oil content resulted higher in W than in S (36.6 vs 29.5%) and in D2 than in D1 (34.5 vs 32.2%). The most abundant fatty acid was the linolenic acid (25.0-38.2%), followed by linoleic acid (15.7-25.4%), while erucic (2.8-3.7%) and stearic (2.2-3.1%) acids resulted the fatty acids present at lower amounts. The oil composition got in W season was characterized by a higher content of linolenic acid (+22%) and a lower linoleic (-25%) than the S crop.
