The objective of this study was to compare the responses of five Jerusalem artichoke genotypes (JA60, JA125, JA5, JA89, and HEL65) to three water regimes (100% available water (AW; field capacity), 50% AW, and 25% AW) for inulin content and inulin yield. The experimental results showed that water regimes and Jerusalem artichoke genotypes were significantly …

Effect Of Different Irradiation Sources And Doses On Haploid Embryoinduction In Altinbas (Cucumis Melo L. Var. Inodorus) Melons, Bariş Dal, Nebahat Sari, İlknur Solmaz

Turkish Journal of Agriculture and Forestry

In vivo induction of parthenogenesis using an irradiated pollen technique provides successful results in melon and accelerates breeding by shortening the time for obtaining 100% homozygous lines. Gamma rays (cobalt-60) are usually used for the pollen irradiation, although it is difficult to find a suitable source for irradiation. Haploid technology is widely used in melon breeding programs, so there is a need to find alternative sources for pollen irradiation. This study was performed to compare the efficiency of different irradiation sources to induce haploid embryos. One dose of cobalt-60 (300 Gy), two different doses (200 Gy and 300 Gy) of …

Private Market Alternatives For Maintaining Wetland Viability In Coastal Louisiana: A Double-Hurdle Approach, Hua Wang

LSU Doctoral Dissertations

The coastal zone of Louisiana contains more than three million wetland acres, or about 40 percent of the nation’s total. Since 1930, Louisiana has experienced a net loss of over 1,900 square miles of coastal wetlands. Currently at risk are the remaining coastal wetlands, 80 percent of which are under private ownership. The acceptance of private wetland owners to restoration programs and their participation in these programs are critical if future coastal restoration efforts are to be successful. Gaining the cooperation by the coastal landowners, however, is complicated by the fact that while the public benefits accruing from wetland protection …

Utah Air Quality: Pm 2.5, Randy Martin, Roger Coulombe, Roslynn Brain

All Current Publications

Particulate matter two-point-five (PM_2.5) is a tiny suspended particle of air pollution that can penetrate deeply into our lungs and potentially enter the bloodstream. The 2.5 unit means that the particles are smaller than 2.5 micrometers (a micrometer is one millionth of a meter). In Cache Valley and along the Wasatch Front, these tiny particles form and accumulate to unhealthy levels when air is trapped in the bottom of the valley during cold winter days.
