Abstract
Climatic change-induced environmental stresses affect crop production. Drought is such a stress which affect crop production and landscaping adversely. Native plants are great for low water use landscaping and can adapt to the natural environment. USU Center for Water-Efficient Landscaping has released a list of native plants that can be used for this purpose. This study focuses on a native plant Ceanothus velutinus (snowbrush) which is an evergreen plant native to western North America. It thrives well in harsh conditions and can act as ornamental plant in low water use landscaping but is difficult to propagate under landscape conditions. Here, we are investigating the effect of microbes in the native soil of snowbrush on the cutting propagation and growth and development of snowbrush in greenhouse conditions. The effect of native soil on cutting propagation showed increased rooting and callusing (13.33%) and survival rate (7.5%) in treatment cuttings when compared to control rooting and callusing (3.125%)and survival rate(2.09%) under 50% native soil inoculation after two months of transplantation. The snowbrush plants from cuttings and seedlings in greenhouse conditions were grown in 1gallon pots inoculated with 200ml of native soil showed an improved growth, higher NO3 content (2.5 and 2.6 folds), higher number of secondary shoots (6.8 and 2.3 folds), and an increased plant width (3.3 and 1.3 fold) compared to control. The treated seedling plants also showed nodulation whereas no nodulation was observed in control. The microbial diversity analysis of the treated cuttings plants showed the presence of the same PGPR as in the native soil. These results showed a significant role of rhizosphere microbes in the improvement of cutting propagation and growth of snowbrush plants in greenhouse conditions. Further, we intend to develop a propagation method from snowbrush cuttings for low water use landscaping by identifying the PGPR in treatment plants.
