To produce large elephant garlic (Allium ampeloprasum L.) bulbs in the southeastern United States, stock cloves must be planted in the fall. During extremely cold winters, however, winter survival rates can be very low. A 2-year study was undertaken to examine practices to increase winter survival rates. Two clove sizes (≤20 g or >20 g), three nitrogen rates (112, 224, and 336 kg/ha), and three planting methods (flat, mulched, and hilled) were tested in a RCB design with four replications. For all planting methods, cloves were set in a shallow trench and covered with soil to ground level. This was also the flat treatment. For the mulched treatment, 7 cm of straw was spread on top. For the hilled treatment, soil was mounded 10 to 15 cm high over the ground level. Cloves were planted in early October and harvested in mid-June. Use of large planting stock cloves increased winter survival rates during the harsh winter, but had no effect during the mild winter. Both years, winter survival was reduced with the flat treatment. Yields of marketable bulbs were 4 to 5 times higher when >20 g cloves were planted than when ≤20 g cloves were used. Nitrogen rate and planting method had no effect on yields. The >20 g cloves also produced larger bulbs than the smaller cloves. Of the three planting methods, the flat treatment produced the smallest bulbs. Bulbs were much larger following the mild winter than the harsh winter.

Abstract Tibetan hulless barley (“qingke” in Chinese) is a valuable food in Tibet. Purple qingke (PQK) and black qingke (BQK), two special pigmented types of hulless barley, have traditionally been widely cultivated and consumed in Tibet for thousands of years. The composition and contents of anthocyanins of two cultivars are unknown. This study aimed to explore the composition and contents of anthocyanins of two cultivars and their antioxidant capacities. Six anthocyanins were identified by ultra-performance liquid chromatography-quadrupole-time of flight mass spectrometry from barley, most of the anthocyanins were acylated by malonyl group. The total anthocyanin contents ranged from 141 to 2,304 μg/g in PQK and from 248.7 to 2902.9 μg/g in BQK. Furthermore, qingke has strong antioxidant activity against DPPH, ABTS˙+, and FRAP. Qingke may be useful for treating or preventing diseases caused by the overproduction of radicals.
