As one of the important materials in landscaping for flower terrace and border, Petunia hybrida needs high environmental conditions and its growth is seriously influenced by the drought. Silicon is considered to be a necessary element for plant growth, and soluble silicon can improve plant resilience. To improve the drought resilience of Petunia hybrida, the silicon transporter protein OsLsi1 and...
Degenerate primers were designed based on the conserved sequences of the Actin gene from other plants. Total RNA was extracted from the leaves of Iris lacteal var.chinensis Fisch.Koidz. Actin gene fragment was obtained by reverse transcription polymerase chain reaction (RT-PCR) and cloned into pMD18-T vector. The positive clone identified by PCR was sequenced. The sequencing result showed that the...
In order to study the alkali resistivity of VHA-c in Iris lacteal. (IrlVHA-c), the transgenic tobacco seedlings harboring IrlVHA-c gene from Iris lactea (T 0 ), the self-crossed progeny (T 1 ), and the non-transgenic lines of tobacco seedlings were grown in Hoagland nutrient solutions supplemented with 0, 100, 200, 300, 400 mmol • L −1 NaHCO 3 . The MDA content, CAT,...
Saponaria officinalis L. seeds were treated with different concentrations of chemical mutagen to determine the impact of media with various hormone concentrations on the induction of mutated (Saponaria officinalis L.) seeds' adventitious buds and rooting culture by using tissue culture technology. The results indicated that the optimum concentration of the chemical mutagen-EMS was 0.3%; the optimum...
Through analyzing the current urban greenbelt construction and relative issues during the development in northeastern parts in Harbin of China, some feasible solutions were proposed. In order to improve the urban ecological environment and upgrading the constructive level of the urban greenbelt along with the sustainable development in the future, the paper provided some solutions in details.
