Moisture stress conditioning, potassium nutrition, and tolerance of Salvia splendens 'Bonfire' to moisture stress
… Salvia splendens 'Bonfire‘ as influenced by moisture stress conditioning (MSC - exposing plants to 4 sublethal dry-down cycles) and potassium (K) nutrition. Plants were fertilized with one of six K rates: 25, 75, 150, 300, 450, and 600 ppm as KCl in experiment one. Seven weeks after seeding …

Yield and water-relation responses of soybeans to single and multiple periods of soil-moisture stress
… physiological and yield responses to water stress were studied in a movable weather (rainout) shelter facility at Ames, Iowa, during the summer of 1978. Soil-moisture deficits were induced in six combinations of three stress periods during reproductive growth to investigate the possibility …

The effect of seaweed concentrate on turfgrass growth, nematode tolerance and protein synthesis under moisture stress conditions
… to determine the effects of salinity and moisture stress on the pathogenicity of root-knot nematodes (RKN) in turfgrass plants. The results indicated that RKN infection adversely affected both visual and functional parameters of bentgrass. Salinity and moisture stress further exaggerated …

Physiological response of loblolly pine seedlings to moisture-stress conditioning and their subsequent performance during water stress
The effect of moisture stress conditioning on the drought tolerance and performance of three open-pollinated families of loblolly pine (Pinus taeda I.) during water stress were investigated. Seedlings were subjected to prolonged sublethal drought treatments which included a watered control, a …

The influence of low moisture stress on the gas exchange and thylakoid activity of loblolly pine (pinus taeda) and aleppo pine (pinus halepensis)
… to determine the influence of sublethal water stress on the physiology of loblolly and Aleppo pine. Gas exchange characteristics, uncoupled thylakoid electron transport capacity, and needle osmotic potentials were measured. Seedlings of both species were watered only when their needle water …

Improving Soil Moisture Assessment of Turfgrass Systems Utilizing Field Radiometry
… using time-domain reflectometer (TDR) soil moisture sensors can decrease water usage. Still, TDR measurements are time-consuming and only cover small scales, leading to many locations being unsampled. Remotely sensed data such as the normalized difference vegetation index (NDVI) offer the …

Variation in Drought Tolerance Attributes Among Tepary Bean (Phaseolus acutifolius) Germplasm
… was evaluated before and after the soil moisture stress treatment which was imposed on the trial by withholding water for 21 days. A 6 x 7 rectangular lattice design replicated three times was used for evaluating 42 genotypes. The results showed that prior to soil moisture stress, there …

Drought-Tolerance Comparison of Aleppo Pine and Brutia Pine Seedlings
… sampled seedlings were subjected to water stress by withholding irrigation. During this period, foliage and root characteristics of seedlings not under moisture stress were recorded. Pinus halepensis showed the greater ability to endure moisture stress and to maintain a higher level of …

Development, implementation, and economic evaluation of an integrated pest management program for alfalfa in Virginia
… experiments evaluating the interaction of moisture stress and defoliation by AW larvae indicated that yield response of alfalfa to AW feeding is dependent on moisture stress levels. Field studies on the influence of AW feeding on alfalfa confirmed the importance of moisture stress in …

Greenhouse growth of Pinus x rigitaeda seedlings in response to water stress and correlations with 7 year plantation performance
… crosses were grown in a greenhouse under two moisture regimes. Water stress decreased growth in every case in every variable measured. Water stress also elicited some genetic differences in the pitch pine and loblolly pine that were not apparent under the non-stressed treatment. The major …

Mine soil properties influencing white pine (Pinus atrobus L.) growth in Southwest Virginia
… L.) trees were used to identify minesoil, plant moisture, and foliar nutrient properties influencing white pine growth on reclaimed mine sites in southwest Virginia. PRESSAll (SAS Views, 1984) was used to determine relationships between soil properties and growth, soil properties and functional …

Influence of temperature, soil moisture, and planting depth on germination and emergence of 'Packman' broccoli
… poor stand establishment. Temperature and soil moisture conditions in Southside Virginia during July and August are often less than favorable for seedling growth. Experiments were designed to test the temperature and moisture stress limits for germination and emergence of 'Packman' broccoli, …

The combined effects of fertilization and relative water limitation on tissue water relations, hydraulic parameters and shallow root distribution in loblolly pine (Pinus taeda L.)
… tissue-level responses in loblolly pine to soil moisture limitation in combination with fertilization as well as to more severe soil moisture limitation. We found that neither fertilization alone, nor fertilization in combination with soil moisture limitation resulted in changes to shoot tissue …
