Optimum harvest maturity for Leymus chinensis seed.

Lin J, Wang Y, Qi M, Li X, Yang C, Wang Y, Mu C - Biol Open (2016)

Bottom Line: At this date, the colours of the seed and lemmas reached heavy brown and yellow, respectively.Thus, Leymus chinensis can be harvested at 39 days after peak anthesis based on the changes in parameters.Colour identification can be used as an additional indicator to provide a more rapid and reliable measure of optimum seed maturity; approximately 10 days after the colour of the lemmas reached yellow and the colour of the seed reached heavy brown, the seed of this species was suitable for harvest.

Fresh weight (TSFW) and dry weight (TSW) of 1000 Leymus chinensis seeds during seed development in 2009 and 2010. Seed weight (both TSFW and TSW) increased with seed development. The maximum 1000-seed weight over the two years was at 33 DAPA and did not change significantly with further seed development. Error bars indicate the standard error from means of TSFW and TSW at P=0.05 (n=8).

BIO017780F2: Fresh weight (TSFW) and dry weight (TSW) of 1000 Leymus chinensis seeds during seed development in 2009 and 2010. Seed weight (both TSFW and TSW) increased with seed development. The maximum 1000-seed weight over the two years was at 33 DAPA and did not change significantly with further seed development. Error bars indicate the standard error from means of TSFW and TSW at P=0.05 (n=8).

Mentions: The changing rule of the 1000-seed weight of L. chinensis in 2009 was similar to 2010. The dry weight of L. chinensis seeds was significantly affected by the year, seed age and their interactions. Although the fresh weight was also significantly affected by the year and seed age, the influence of their interactions was not significant (Table 2). The seed weight increased with seed development, which was shown at 6-18 DAPA when the 1000-seed weight significantly increased due to the rapid accumulation of dry matter and the decreased moisture content (P<0.05). The maximum 1000-seed weight over the two years was at 33 DAPA and did not change significantly with further seed development (Fig. 2).Table 2.
