辽宁省审定的直立穗型水稻品种中，有2／3的品种直立穗型基因来自意大利古老品种巴利拉，而且与辽粳5号亲缘关系密切，遗传基础狭窄，异质性差，具有遗传脆弱性，容易造成因垂直抗性丧失而罹患大面积病虫害的不良后果。

The variation rates of four wheat lines were 2%~3%. The characters of SP1 variation plants at maturity stage also appeared big changes. SP1 variation plants had short growing period, high seed setting rate, loose plant-type and clavated spike-type. There were not consistent change in plant height, the number of spike grain and the weight of 1000 kernel among four lines.

In the cuttage of rose ,five stromata were adopted in order to study their influence on the growth of the branches. The result of the experiment shows that vermiculite can ensure the highest survival rate. In the experiment, epicormic branches are treated with IBA at different concentration. The result shows that 200mg/L IBA can also promote the epicormic branch to root. The rooting rate is 91.0%. Temperature plays an important role in rose cuttage.

研究了5种不同基质对多头玫瑰插穗扦插繁殖的影响，结果表明：不同基质扦插成活率不同，以蛭石最好；在试验中，用吲哚丁酸IBA不同浓度溶液处理扦穗，结果表明： 200mg/L吲哚丁酸IBA对多头玫瑰扦插生根有很大的促进作用，生根率为91%；温度对多头玫瑰的扦插也有很大的影响。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
