5种禾本科草坪草种子的吸水特性
|
摘要
探寻禾本科草坪草种子动态吸水规律,以5种常见禾本科草坪草种子为材料进行吸水试验,并对其进行动态回归与相关性进行分析。结果表明:禾本科草坪草种子吸水量和吸水率随吸水时间延长而增加;单位时间内吸水量表现为前9 h变化幅度较大,平均增加幅度都在18.09%以上,9 h后增加幅度较小,都在9.36%以下;单位时间内吸水率增加幅度随时间延长呈现先升后降的变化趋势,0～9 h时间内增加幅度较大,平均增加幅度都在16.13%以上,9 h之后增加幅度降低在10.23%以下。高羊茅、匍匐剪股颖、草地早熟禾、无芒雀麦种子吸水率随吸水时间的回归模型为三次函数,多年生黑麦草的为对数函数,其相关性都达到极显著水平(P<0.01)。禾本科草坪草种子不同时间段的吸水量、吸水率均达极显著正相关(P<0.01),随时间延长相关性逐渐增大,但吸水量与吸水率间均未达显著相关(P>0.05)。变异分析表明,吸水量的变异系数以吸水4 h为最大(15.23%),而吸水率变异系数以吸水9 h为最大(14.88%)。因此,吸水4 h时的吸水量和吸水9 h时的吸水率可分别衡量禾本科草坪草种子吸水量和吸水率的基因型差异。
Five gramineous turfgrass seeds were used as materials to reveal the dynamic water absorption, and the dynamic regression and correlation were analyzed. The results showed that water absorption and water absorption rate of gramineous turfgrass seeds increased with the prolongation of water absorption time. The water uptake per unit time showed a large change in the first 9 h, with an average increase of more than 18.09%, and a small increase of less than 9.36% after 9 h. The increase range of water absorption per unit time increased first and then decreased with time. The water absorption rate per unit time showed a large change in the first 9 h, with an average increase of more than 16.13%, and a small increase of less than 10.23% after 9 h. The regression model of water absorption rate of tall fescue, creeping bentgrass, bluegrass and bromus inermis seeds with water absorption time was a cubic function, and perennial ryegrass was logarithmic function, the correlation reached a significant level(P<0.01). The water absorption and water absorption rate of grass seeds in different time periods were significantly positively correlated(P<0.01), and gradually increased with time, but there was no significant correlation between water absorption and water absorption rate(P>0.05). Variation analysis showed that the coefficient variation of water absorption was the largest at 4 h(15.23%), and the coefficient variation of absorption rate was the largest at 9 h(14.88%). Therefore, water absorption at 4 h and water absorption rate at 9 h could measure genotype differences of grass seeds respectively.
