Abstract:
The effect of physiological age (shoot age at propagation) and site on microfibril angle was examined for seedlings (physiological age = 0 years) and cuttings (physiological age = 5-16 years) of Pinus radiata D. Don. Two trials were examined by measuring microfibril angle in alternate growth rings on breast height discs. In the first trial, two sites were compared for ll-year-old trees propagated from seedlings, and cuttings of comparable genotype, at 0 and 5 years physiological age, respectively. In the second trial, a single site was examined comparing 25-year-old trees propagated from open

The aim of the study was to determine changes in physiological indicators in lambs subjected to gentle stroking. The study included 40 three-week-old lambs (20 females of the synthetic prolific-meat (BCP) line and 20 females of the Świniarka (SW) breed). The animals were assigned to two control groups (n = 20) and two experimental groups (n = 20). Lambs from the experimental groups received treatment.

Climate change influences the ecological environment and affects the recruitment of plants, in addition to population dynamics, including Scots pine regeneration processes. Therefore, the impact of cover-dominant species extracts on the germination of pine seeds and morpho-physiological traits of seedling under different environmental conditions was evaluated. Increasing temperature reinforces the plant-donor allelochemical effect, reduces Scots pine seed germination, and inhibits seedling morpho-physiological parameters.

The effect of anti-EGF became less prominent as the treatment was started at later times: when it was given from day 7, no delay in eyelid opening was observed.

Problem statement. As individuals transition from middle age to old age, it is important for those in their middle age to adapt to and sustain a consistent level of physical activity. Aqua training can serve as a beneficial form of exercise for middle-aged women. Approach. This study investigates the effects of aqua aerobics on the physical and physiological parameters of women in their middle age. The study included 40 women (aged 35 to 45 years) from Kakching in Manipur, who were randomly assigned to either the experimental or control group. Methods. Over a 12-week period, the experimental g

Drought and flooding are some of the most common stressful conditions for plants. Due to the recent climate changes, they can occur one after another. This study is focused on the effect of antagonistic abiotic stress such as drought and flooding on the different metabolites from Ocimum basilicum leaves. Six-week-old plants of Ocimum basilicum were exposed to drought or flooding stress for 15 days, followed by antagonist stress for 14 days. The assimilation rates decrease drastically for plants under consecutive stresses from 18.9 to 0.25 µmol m−2 s−1 starting at day 3 of treatment. The stomat

Plants were harvested after 14, 16, 19, or 22 days of exposure. During Cu2+ treatment, shoots appeared healthy, but roots turned golden, with increased lateral branching and tip browning. Cultivars responded identically for all characteristics measured. Root Cu concentrations were >3000 μg·g−1 or 300 times the control after Cu2+ treatment. Shoot Cu concentrations (13 μg·g−1

However, it remains an open question whether the chronological age of the donor organism affects the effectiveness of the use of MSC.
