Effects of walnut/ compound planting on growth, fruit yield, quality of and soil properties.

Walnut and are important arbor and shrub fruit trees cultivated in the southwest mountainous area of China. Furthermore, those two species are compound cultivated in this area. In this study, we investigated the growth, yield, fruit quality, photosynthesis, and soil fertility of in a 7-year typical 'Qianhe 7'/ 'Guinong 5' compound planting pattern in Guizhou.

Within-visit and between-visit intra-individual blood pressure variability in an unselected adult population from rural China.

Objective: To assess the association between the variability of blood pressure (BP) readings within an initial clinic visit, the variability within subsequent visits and the variability between visits over 1 week in a general population.

Methods: This study included 1401 adult residents, who were not taking antihypertensive drugs, having BP measurements at three visits over 1 week. The difference between maximal and minimal BP readings (ΔBP), ΔBP/BPm (the mean BP value in a visit), the standard deviation (SD) and coefficient of variation (coefficient of variation = SD × 100/mean) of three BP values in each visit were used to estimate the within-visit BP variability (BPV).

The impact of changes in population blood pressure on hypertension prevalence and control in China.

In China, there are approximately 250 million adults who have hypertension with low rates of awareness, treatment and control. Changes in lifestyles at a population level have the potential to enhance or deteriorate the prevention and control of hypertension. We used data from a regional hypertension survey to examine the impact of 2/1 mm Hg decreases or increases in population blood pressure on hypertension prevalence, and rates of unawareness of the hypertension diagnosis, treatment, and control.

The usefulness of 24-hour blood pressure monitoring for the patients with atrial fibrillation: based on the variability of blood pressure parameters.

Objective: The aim of this study was to test whether ambulatory blood pressure monitoring (ABPM) in patients with atrial fibrillation is reliable as in patients with sinus rhythm.

Method: This study included 92 persistent atrial fibrillation patients (50% females; mean age 70.49 ± 11.

[Effects of different mulching materials on nitrate metabolism in soil of apple root-zone in summer and autumn.].

This study explored the effects of mulching straw mat, agricultural carpet, transparent-plastic film and horticultural fabric on nitrification-denitrification, nitrate reductase (NR), nitrite reductase (NiR), ammonium, nitrate and nitrite nitrogen in root-zone soil grown with three-year old apple trees (Malus domestica cv. Starkrimson) during summer and autumn. Results showed that the four treatments decreased nitrification intensity in summer soil, NiR activity in summer-autumn soil and the variation coefficient of nitrification-denitrification intensity and NR in both summer and autumn soil.

[Relationship between drought resistance and endogenous hormone content in different citrus species].

Eight plant seedlings of citrus species, Citrus tangerina, C. erythrosa, C. chuana, Poncirus trifoliate, C.

[Relationship between ascorbic acid accumulation and related enzyme activities in fruit of Rosa roxburghii Tratt].

Ascorbic acid (AsA) and sugar levels, together with activities of L-galactono-1,4-lactone dehydrogenase (GalLDH, a key enzyme in AsA biosynthesis in higher plant), AAO, AAP, MDAR and DHAR in fruit of Rosa roxburghii Tratt were measured during development. The result showed that AsA accumulated continually but with a slow, fast and slow accumulating rate in the R. roxburghii fruit during its development, in which the period from the end of June to the early of August was the most important period of AsA accumulation, since the AsA accumulated in this stage accounting for approximately 90% of the final level (Fig.
