“…Environmental factors and plant traits can influence seed viability and germination (Jing et al, 2007, Walck et al, 2011, Baskin and Baskin, 2014, Adie et al, 2019). Under favorable soil temperature and moisture conditions, viable seeds can germinate when they are nondormant (dormancy → nondormancy) (Ye et al, 2019, Wang et al, 2022), while unfavorable environmental conditions such as inappropriate temperature and darkness may induce nondormant seeds back into dormancy (nondormancy → dormancy) (Baskin and Baskin, 2014).…”

Environmental factors, such as temperature and moisture, and plant factors, such as seed position on the mother plant, can affect seed viability and germination. However, little is known about the viability and germination of seeds in different positions on the mother plant after burial in soil under natural environmental conditions. Here, diaspores from three positions on a compound spike and seeds from two/three positions in a diaspore of the invasive diaspore‐heteromorphic annual grass Aegilops tauschii were buried at four depths for more than 2 years (1–26 months) under natural conditions and viability and germination monitored monthly. Viability of seeds in each diaspore/seed position decreased as burial depth and duration increased and was associated with changes in soil temperature and moisture. Germination was highest at 2 cm and lowest at 10 cm soil depths, with peaks and valleys in autumn/spring and winter/summer, respectively. Overall, seeds in distal diaspore and distal seed positions had higher germination percentages than those in basal diaspore and basal seed positions, but basal ones lived longer than distal ones. Chemical content of fresh diaspores/seeds was related to diaspore/seed position effects on seed germination and viability during burial. We conclude that seeds in distal diaspores/seed positions have a ‘high risk’ strategy and those in basal positions a ‘low risk’ strategy. The two risk strategies may act as a bet‐hedging strategy that spreads risks of germination failure in the soil seed bank over time, thereby facilitating the survival and invasiveness of A. tauschii.

The optimum performance of the cowpea plant population in the field could be determined by their seed quality. The research aims to evaluate the seed quality of several cowpea local varieties after being stored in the form of seeds and pods. A total of 18 cowpea local varieties from East Java, West Nusa Tenggara, South Kalimantan, and West Sulawesi were evaluated for their seed vigor and viability after being stored for 30 and 60 days at room temperature using plant material in the form of seeds and pods. The seed multiplication was conducted in the field at Banyuwangi, and the seed quality test using sand media was carried out at the glasshouse of ILETRI Malang. The storage of cowpea in the form of pods and seeds for up to 30 days did not significantly affect the seed quality. Four local varieties (VU 0007, VU 0093, VU 0125, VU 0155) showed good viability at the storage of 30 and 60 days, respectively. The VU 0032 and VU 0076 have optimum viability after being stored for 60 days. The speed of the germination index (SGI) was not only describing the level of vigor but also able to show the type of plant material to be stored. The VU 0007, VU 0093, and VU 0155 were recommended to be stored in the form of seeds, meanwhile, the VU 0125 can be stored for up to 60 days in the form of seeds or pods. The morphological characters of sprouts, namely hypocotyl length, stem dry weight, and root dry weight, could be considered as a benchmark parameter for seed vigor of cowpea.
