The analysis of correlation indicated that tobacco breeding with higher potassium content has the characteristics of higher stalk height, wider stalk circumference, longer leaf and more leaf number comparatively. The correlations between potassium content and nicotin among top, middle and bottom tobacco leaves were all negative. The correlation among potassium content and malondialdehyde,superoxide dismutase, conductance ratio; and protein, solubility sugar, chlorophyl and free water/bondage water were all attained marked level, however, the essence of correlation was different: the former was negative but the latter was positive. 4.The analysis of heterosis demonstrated there were different degree heterosis in the potassium content of tobacco leaf and other correlated characters, including agriculture, physiology and biochemistry.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
