(1967) reasoned that since the lemming probably disappeared from the area about 10,000 yr ago, when postglacial warming began, the seeds were at least 10,000 yr old. In China, F. convolvulus is found in thickets in valleys and along stream banks, at 100-3600 m (Flora of China Editorial Committee, 2015). On the other hand, application of molybdenum to soil where plants of T. aestivum were growing reduced preharvest sprouting, but if phosphorus was applied along with molybdenum there was an increase in germination percentage (Modi, 2002).

Aphelenchoides fragariae (Ritzema Bos, 1891) Christie, 1932 in Lilium regale Wils,. The general importance of this weed is due to its ability to emerge throughout the growing season. Kazantseva AS; Tuganaev VV, 1972. Zubkov A F, 1987. Initially it is white, but gradually darkens over the two-week period the insect remains in this stage. It can be distinguished from the non-native and weedy Black-bindweed ( Fallopia convolvulus ) which has less distinct leaf veins and unbranched, sparser racemes of flowers which barely open, and it also lacks the ring of cilia hairs at the base of the ocreae. Pochvoznanie, Agrokhimiya i Rastitelna Zashchita, 22(3):118-124; 6 ref. By climbing up the crop, F. convolvulus causes lodging in grain crops (Neururer, 1961; Hume et al., 1983), and can cause harvesting problems when its vines wrap around moving parts of machinery (Forsberg and Best, 1964; Fabricius and Nalewaja, 1968).

Currently, it is listed as invasive in the Dominican Republic, Cuba, Australia, New Caledonia, and New Zealand (Webb et al., 1988; MacKee, 1994; Wilson, 2008; Acevedo-Rodriguez and Strong, 2012), but it is also ranked as a serious weed in 20 crops in more than 41 countries around the world (Holm et al., 1991).

After 20 yr of burial, 2986 seeds m−2 were identified by the germination method, with Rumex obtusifolius being dominant and Carex oxyandra, Poa pratensis and Viola grypoceras quite common (Tsuyuzaki and Goto, 2001). Seeds from plants of Senna obtusifolia watered at 1-, 2- and 7-day intervals with 25%-strength Hoagland’s solution did not differ significantly in germination (Tungate et al., 2002). Prior to flowering, F. convolvulus may be mistaken for Convolvulus arvensis, as both have twining greenish stems and leaves of similar shape.
