“…3) Black seeds are sensitive to light, salinity, temperature and their interaction (Li et al, 2008a) and remain dormant in saline soils. Similar results have been reported in Atriplex sagittata (Mandák and Holmanová, 2004), rape seed (Zhang et al, 2006), and S. salsa and S. aralocaspica (Li et al, 2008b;Wang et al, 2008).…”

“…Recent reports showed that A. centralasiatica produces two types of seeds, brown and black seeds, and the difference in the two types of seeds was mainly in seed coat (Li et al, 2008a). The seed coat has been suggested to influence storability in some species, such as rapeseed (Zhang et al, 2006), Suaeda salsa (Li et al, 2008b) and S. aralocaspica (Wang et al, 2008), because of differences in thickness and water absorbing ability.…”

The effect of cold stratification, seed coat scarification and plant hormones on germination of black and brown seeds of Atriplex centralasiatica under saline conditions was investigated. Cold stratification increased the germination rate, but did not affect final germination percentage of either brown or black seeds. Seed coat scarification and fluridone (Abscisic acid [ABA] biosynthesis inhibitor) improved germination of both types of seeds under salinity stress. In both brown and black seeds, gibberellin, 1-aminocy-cloproane-1-carboxylate (the immediate precursor of ethylene) and 6-benzyladenine, had little effect on the germination under salinity. Paclobutrazol (inhibitor of gibberellin biosynthesis) and ABA did not affect germination in distilled water, whereas ABA inhibited germination in saline conditions for both types of seeds. Paclobutrazol inhibited the germination of black seed only under salinity. Black seeds were more sensitive to ABA than brown seeds in salinity stress. Brown seeds contained more active gibberellins than black seeds, although they contained a similar level of ABA. In conclusion, the production of black and brown seeds showed bet-hedging ecological strategies. Gibberellins in seeds and ABA in seeds and bracteoles were the main plant hormones that affected the germination of dimorphic seeds.

“…The yellow-seeded B. napus was also found to have some defects in seed germination and storage characteristics. The yellowseeded rapeseed (B. napus L.) genotype showed significant lower abilities to protect the embryo against adverse environmental conditions in artificial ageing, deteriorate at faster rate than black-seeded in radiation, have reduced field emergence when excessive water occurs in field production and have poor storage ability (Zhang et al 2006b;Chen et al 1997). …”

In this study, the correlations among these characters were investigated in 18 rapeseed (Brassica napus L.) accessions with different seed coat color. The results indicated that seed water uptake and flooding tolerance were significantly correlated with seed color and melanin pigment content of testa. The red or black-seeded accessions had higher melanin content in testa, showed slower water uptake and lower leakage and higher flooding tolerance. The majority of yellow-seeded rapeseed accessions which had low melanin pigments content in testa showed a rapid water uptake and higher leakage than the red or black-seeded, which led to imbibition damage and lower flooding tolerance. The results suggest that the yellow-seeded cultivars experienced poor field emergence and more serious pre-harvest sprouting in raining weather than the dark-seeded cultivars. Some yellow-seeded accessions showed a slow imbibition behavior and relative high flooding tolerance, indicated these accessions can be used as a genetic resource to improve the flooding tolerance and reduce imbibition damage for the yellow-seeded B. napus L.
