Aqueous extract of cotton has allelopathic effect on Raphanus sativus, Brassica campestris, Lactuca indica, Brassica campestris, Echinochloa crusgall, Setaria viridis and Abutilon theophrasti and its inhibition effect gradually strengthens with increasing concentration. Aqueous extracts from stems, leaves and roots of cotton inhibit or accelerate seed germination and seedling growth, and activity of enzyme of seedling root of cotton. While aqueous extracts from stems and leaves of cotton are 0.02 gmL^(-1), root length, shoot length, lateral root number and dry weight of cotton respectively increase by 10.3%, 3.1%, 22.9% and 2.4% over the control. The above mentioned indexes are lower than the control by 34.4%, 39.2%, 40.6% and 19.0% respectively as the aqueous extracts are 0.1 gmL^(-1). At the same time, root activity and SOD activity decrease by 38.2% and 36.7%, while POD activity and MDA content increase by 52.3% and 36.5%. Growth indexes of plant receptors increase at low concentrations but decrease at high concentrations of aqueous extracts. The allelopathic effect of aqueous extract of stems and leaves is stronger than that of root.

The outer side of the tepals can be anything from deep red to orange red, and the inner side is most frequently creamy yellow or pink-red but you can also find the scarlet ones. Leaves are blue-green. The plant is a climbing semi-perennial - only the base of the stems is woody. Stems reach up to 3 m and twine around the supports by leaf petioles

The results showed that the POD activity was higher in the sporophyll than that in the stems and leaves in which the POD activities were weak from bottom to top in native plant. For the Japanese plant, the POD activities of the stems and leaves were the same in all positions. However, the activity was slightly higher in mid-portion of a leaf than that in stems. The high enzyme activities were observed in mid-bottom stems in the half-bred plant, and the activity was higher in bottom leaf than that in mid-top leaf.

结果表明：3个裙带菜群体的POD同工酶其孢子叶活力都相对强于其它部位；日本裙带菜茎和叶的各部位POD酶活力相同，但叶中部的酶活力稍强于茎；自育裙带菜茎底部和茎中部的POD酶活力较强些，而叶底部的酶活力较叶中部和顶部的强；本地裙带菜的茎和叶由底部到顶部POD酶活力逐渐变弱。

Laboratory bioassay was conducted to determine the antifungal activities from the root, stems and leaves extracts of Mirabilis jalapa. The results showed that the methanol extracts of Mirabilis jalapa roots and stems had better inhibition actions to mycelial growth of Alternaria kikuchiana Tanaka and Colletotrichum orbiculare.

GUS staining shows that GUS gene was expressed in stems, leaves, calyxes, stamens and siliques in transgenic Arabidopsis plants, with higher expression in green tissue such as stems, leaves, siliques, while invisible in roots, petals, and seeds. The data indicate that MPBQ MT gene promoter was likely to be expressed preferentially in green tissues such as stems, leaves, and young siliques.

GUS组织化学染色结果表明，在MPBQ MT启动子驱动下，报告基因GUS在拟南芥的茎、叶、花萼、雄蕊、种荚均有表达，且在茎、叶、种荚中表达量较高，而在根、花瓣和种子中则没有观察到GUS基因的表达，表明MPBQ MT基因可能仅在拟南芥幼嫩茎、叶、种荚等绿色组织中特异性高表达。
