“…However, there was a strange phenomenon regarding apple roots in the region covered by white clover: in May, there were fewer roots than under monoculture conditions, but in July and October, apple developed many roots in this region. Cover crops can improve soil microbial activity thereby enhancing the nutrient release and affect of the root exudates on the content and accumulated amounts [38,39]. Therefore, we speculate that this was probably because the roots of white clover released some root exudates that activated soil nutrients, which led to the development of apple roots in this region forming a beneficial relationship.…”

Intercropping can introduce greater plant diversity and functional complementarity in an arable crop system but inter-and intracompetition can between intercropped crops. The rhizo-box was established of apple-white clover intercropped system to examine the competitive relationship between intercropped crops on the Loess Plateau. The results showed that the competitive relationship between intercropped crops was dynamic and changed with the crop competitiveness. Crop competitiveness was characterized by root development, although intercropping inhibited the development and nutrient accumulation aboveground of apple trunks and branches, intercropped apples still maintained a larger root system than under monoculture and the root morphology of intercropped apples changed significantly. White clover had lower competitiveness than apple at the beginning of the year, which was reflected in the inhibited development in May. However in July and October, intercropped white clover had more biomass and nutrient accumulation than under monoculture. ARTICLE HISTORY

“…Organic acids are important plant root exudates, which can regulate the osmotic balance of plant cells, intracellular pH and ionic concentration 20 . Root organic acids can interact with some metal ions, such as cadmium (Cd), aluminum (Al) 33 , gallium (Ga), copper (Cu), manganese (Mn) and lead (Pb) 34 , chelated to form organometallic complexes 35 , thereby reducing the toxicity of metal ions to plants 36 . Therefore, root secretion of organic acids can be used as a special protective mechanism for plants to cope with acid stress.…”

Pinus massoniana Lamb. is one of the most sensitive species to acid deposition among forest woody plants, but differences in acid resistance among pine families still exist. It is of great significance to study the differences in acid resistance of Masson pine families and to analyze the physiological regulation mechanism of their acid resistance. In this study, the 100-day-old seedlings of 16 Masson pine families were treated with the simulated acid rain (SAR) at different pH levels (5.6, 4.5, 3.5 and 2.5) for 100 days to investigate the plant morphology, chlorophyll content, and root physiological responses. Results showed that pine family No. 35 maintained the good morphology, high chlorophyll content and organic acids secretion, and low plasma membrane permeability exposed to SAR, while family No. 79 presented the opposite. SAR not only increased the root plasma membrane permeability, but also induced an exudation of organic acids from the pine roots, and the test parameters changed sharply when the SAR pH was lower than 4.5. The results indicated that Masson pine could resist to acidic environment (pH 4.5–5.6), and family No. 35 had the acid resistance while the family No. 79 was sensitive to acid stress. The acid resistance diversity of different pine families had close relation with the root physiological processes, including the root plasma membrane permeability and organic acids secretion. For the future research, the natural genetic variation of Masson pine in response to acid stress and its acid resistance mechanism should be further studied.
