Nutrition of container‐grownRadermachera sinicaHemsl.

Abstract

Seedlings of Radermachera sinicaHemsl. were grown in peat/composted bark (7:3, v/v) medium to evaluate their response to five levels of nitrogen (N), phosphorus (P), potassium (K), and lime. R. sinica proved to be an adaptable species quite tolerant of nutrient extremes. There was a strong response to added N with an optimum at 300 g N/m 3 , equivalent to 85 g N/m 3 per month and a leaf N content of 2.5%. P, and more noticeably K, had little influence on foliage growth and consequently there were few nutrient interactions. Optimum P additions were at c. 200 g P/m 3 or a leaf P content of 0.35%, whereas high P fertilisation depressed foliage growth. The lime rate for optimum growth was at 6 kg/m 3 and pH 4.8.

Facile Bioself-Assembled Crystals in Plants Promote Photosynthesis and Salt Stress Resistance

“…Herein, cysteine (Cys) was employed to promote the formation of foliar Mo crystals in this study. As a model plant, Arabidopsis thaliana ( A. thaliana ) is widely employed in plant and agriculture studies, and the roots and fruit of Radermachera sinica ( R. sinica ) are edible and distributed throughout Europe and Asia and are even considered economic crops in some countries . Moreover, the sensitivity of R. sinica to leaf abscission is appropriate for foliar treatment. , Herein, Mo ions were bioself-assembled into micron-sized crystals in the mesophyll cells of R. sinica and A. thaliana , improving the salt stress resistance of these plants.…”
