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.

Moisture content (%) of Leymus chinensis during seed development in 2009 (09MC) and 2010 (10MC). The moisture content decreased with seed development, and the minimum appeared at 36 DAPA for both years. Error bars indicate the standard error from means of MC at P=0.05 (n=8).

BIO017780F3: Moisture content (%) of Leymus chinensis during seed development in 2009 (09MC) and 2010 (10MC). The moisture content decreased with seed development, and the minimum appeared at 36 DAPA for both years. Error bars indicate the standard error from means of MC at P=0.05 (n=8).

Mentions: The moisture content was also affected by seed age (Table 2). As the seed developed, the moisture content decreased and the minimum value appeared at 36 DAPA for both years (Fig. 3). In addition, the electrical conductivity of the seed leachate also decreased as the seed developed, especially at 6 and 9 DAPA. The value reached a steady state at 27 and 30 DAPA in the two experimental years. A two-way ANOVA showed that the electrical conductivity of the seed leachate was significantly affected by the year and the seed age (Table 2, Fig. 4).Fig. 3.
