The effects of recent water stress on distribution of 14C-labelled photosynthate in loblolly pine (Pinustaeda L.) seedlings were examined. Leaves on a lateral branch were allowed to photosynthetically fix 14C, and 14C levels in seven biochemical fractions in the source leaves and in each of five other plant parts were determined 72 h later. Regardless of stress level, about 95% of the 14C originally presented was taken up and 60% was respired during the 72 h translocation period. Most 14C was found in exposed or source leaves and in the roots, with very little occurring above the level of the exposed branch. The bud and nonexposed leaves contained 1.2% or less of the seedling's 14C. As preexposure stress level increased, translocation to roots and other sinks decreased. Sugars contained most of the 14C in parts other than the bud and nonexposed leaves. The proportion of 14C in sugars in these parts increased as stress increased. Structural compounds contained less 14C as stress increased, indicating a lasting effect of stress on growth. In all cases, organic acids and amino acids contained very little 14C. Mild stress resulted in increased starch production in the source leaves relative to no stress, while severe stress reduced starch production.

The relationship between moisture stress and mineral soil tolerance was studied by placing 10 blueberry (Vaccinium) clones in a Berryland sand soil high in organic matter (Berryland) and a Galestown sandy clay loam soil (Galestown) and subjecting them to one of two moisture regimes. The Berryland and Galestown soils represent an excellent blueberry soil and a mineral soil, respectively. A moderate degree of water stress influenced biomass partitioning in blueberries in a similar manner as stress induced by culture on mineral soil. Berryland control plants on Berryland partitioned more biomass into leaves and produced more dry matter and leaf area than plants on Galestown or those moisture stressed. Net assimilation rate and relative growth rate were not significantly different between soil or moisture treatments. The primary reason for the reduction in absolute growth rate due to soil type or moisture stress was a significantly lower leaf area duration on Galestown soil and in-moisture stressed plants. Clones differed in instantaneous transpiration, leaf conductance, and apparent photosynthesis and the ability to partition biomass into various plant parts. By selecting for increased leafiness, a high photosynthetic rate, and a more energy efficient root system, improvement in mineral soil tolerance should be possible.

BACKGROUND: Prediabetes prevalence in the world is increasing, and is estimated to reach20.6% in 2025. Prediabetes prevalence in Indonesia is almost double the prevalence of diabetes mellitus. Prediabetes often does not cause symptoms, but has already started to occur with both microvascular and macrovascular complications in some patients. Stress is a disorder of the body and mind caused by changes and demands of life. Stress that occurs at this time, is part of the effects of modern life, and cannot be avoided, both in the work environment, and school, as well as family and society. In the state of stress the secretion of the hormone cortisol increases, which pushes the pancreas to produce insulin, so that there is an increase in blood sugar levels.OBJECTIVE: This study was conducted with the aim to know the relationship of stress level in prediabetes sufferer and know the description of stress level of prediabetes patient in Sleman Yogyakarta area.METHODS: This research was a quantitative studywith a cross sectional design, done in the working area of first health facility of Sleman Regency, Yogyakarta. Sampling was done by simple random sampling, and research subjects were patients in the working area of Puskemas in Sleman that fulfilled inclusion and exclusion criteria then examined.RESULTS: The mean age of the study subjects was 46.7 years (SD 11.02). The distribution of subjects of the study was 121 females (78.1%), and 34 males (21.9%). Based on a total of 155 respondents, 19 respondents (12.3%) were diagnosed with prediabetes based on TTGO results and 136 people (87.7%) had normal TTGO results. Based on a total of 155 respondents, 69 respondents (47.1%) had a mild stress level, 80 respondents (49%) moderate stress level and 6 respondents (3.9%) had severe stress level. The result of bivariate analysis showed that there was no correlation between stress level and prediabetes occurrence in Sleman Yogyakarta and p = 0.825 (CI 95%: 0.879-1.67) was not statistically significant (p>0.05). Prediabetes prevalence was 12.3% in the study population.CONCLUSSION: There was no correlationbetweenstress level with the occurrence of prediabetes in Sleman Yogyakarta area. Stress levels were moderate among prediabetes sufferers more than mild and severe stress levels.
