Drought stress may alter protein synthesis in turfgrasses. The objectives of this study were to investigate physiological changes associated with the synthesis of dehydrin and a cytosolic-heat shock protein (HSC 70) in response to drought s...
Vehicle-Mounted Optical Sensing: An Objective Means for Evaluating Turf Quality [0.03%]
车载光学传感：评价草坪质量的一种客观手段

Bermudagrass, Cynodon dactylon (L.) Pers., suffers periodic severe winter-kill throughout much of its area of use in the contiguous USA. A research goal is to increase freeze tolerance in cultivars to lessen the risk of such damage. An iden...
Cupule Removal and Caryopsis Scarification Improves Germination of Eastern Gamagrass Seed [0.03%]
Eastern gamagrass种子发芽通过杯状体去除和籽粒处理得以改善
X. Tian,A. D. Knapp,K. J. Moore et al.
X. Tian et al.
Eastern gamagrass (Tripsacum dactyloides L.) is a warm-season, perennial grass with high palatability and productivity. However, poor stand establishment, often due to seed dormancy, limits its widespread use. Seed dormancy is often caused ...
Soybean mosaic virus (SMV) and the SMV Resistance Gene (Rsv(1)): Influence on Phomopsis spp. Seed Infection in an Aphid Free Environment [0.03%]
大豆花叶病毒（SMV）及其抗性基因（Rsv(1)）对无蚜环境下的种子感染的影响研究
Gwen Koning,Dennis M. TeKrony,Said A. Ghabrial et al.
Gwen Koning et al.
Infection of soybean [Glycine max (L.) Merr.] plants with Soybean mosaic virus (SMV) has been reported to enhance Phomopsis spp. infection, which reduces seed quality. The timing and incidence of SMV infection depends largely upon the level...
Radiation Use Efficiency and Biomass Production in Soybean at Different Plant Population Densities [0.03%]
不同密度下大豆群体的辐射截获效率与干物重关系研究
Larry C. Purcell,Rosalind A. Ball,J. D. Reaper rd et al.
Larry C. Purcell et al.
As population density (POP) increases in a soybean [Glycine max (L.) Merr.] crop, maximum light interception (LI) occurs earlier in the season. Earlier canopy closure would be expected to increase the cumulative radiation intercepted. We hy...
Use of Spectral Radiance to Estimate In-Season Biomass and Grain Yield in Nitrogen- and Water-Stressed Corn [0.03%]
基于光谱辐射估算氮素和水分胁迫下玉米生长季生物量及籽粒产量
S. L. Osborne,J. S. Schepers,D. D. Francis et al.
S. L. Osborne et al.
Current technologies for measuring plant water status are limited, while recently remote sensing techniques for estimating N status have increased with limited research on the interaction between the two stresses. Because plant water status...
The Effect of Plant Height on Tan Spot on Durum Wheat in Southern Saskatchewan [0.03%]
