Rowcover Modification Of Carbon And Mineral Nutrient Partitioning In Strawberry (Fragaria Ananassa, Duch), Karen Lynn Brownlee Gast
Rowcover Modification Of Carbon And Mineral Nutrient Partitioning In Strawberry (Fragaria Ananassa, Duch), Karen Lynn Brownlee Gast
Doctoral Dissertations
In cool temperature climates where plant growth may be limited by short growing seasons and low temperature stress rowcovers are being used to increase production of fruit and vegetable crops. Two field experiments were conducted to investigate how floating rowcovers applied during autumn, winter and spring affect plant growth and development. The first experiment, 1985-86, examined mineral nutrient and biomass partitioning in a short-day cultivar, 'Sparkle', and a day-neutral cultivar, 'Fern', in rowcovered and nonrowcovered plants in autumn. The second experiment, 1986-87 examined carbon, nitrogen and biomass partitioning over time in autumn and in spring and development of yield components …

Genetics And Physiology Of Cold Tolerance In Muskmelon (Cucumis Melo L), Mark Gordon Hutton
Doctoral Dissertations
Five hundred muskmelon accessions were evaluated for germinability at 15$\sp\circ$C and classified as cold germinable (CG) or non-cold germinable (NCG). Accessions meeting the following criteria were classified as CG: germination $>$80%, EI $\leq$ 240, HI $\leq$ 265, and CI $\leq$ 290. EI, HI, and CI are mean hours to emergence, hypocotyl elongation and cotyledon expansion respectively. Only 5% of the accessions examined were considered as CG.
Seedling growth of CG (PI 126156, PI 126197, and 'Persia 202') and NCG ('Delicious 51', 'Minnesota Midget', 'Old Time Tennessee', Russian 4141) muskmelon genotypes was compared. Seedlings were grown to 30$\sp\circ$C to the …
