Effects of Diet and Humidity on Drosophila suzukii Flight Performance

Creator:: Wong, Jessica S.
Abstract:: Drosophila suzukii is a global and economically significant pest of berries and other soft fruits. This insect can survive and reproduce under a wide variety of environmental conditions and with a substantial number of cultivated and wild hosts. Management of D. suzukii is commonly done with chemical control strategies. However,...

Effect of floricane number on primocane growth, yield components, and cold hardiness in 'Marion' trailing blackberry

Creator:: Cortell, Jessica M.
Abstract:: In spring of 1993 and 1994, mature 'Marion' (Rubus sp.) plants were pruned to 0, 4, 8, and 12 floricanes. An additional treatment of 0 floricanes with early (30 cm) primocane pruning was included. Primocane growth was measured from emergence in April until growth cessation at the end of October....

Study of Arabidopsis thaliana seed development : occurrence of germinability

Creator:: Hewitt, Jessica
Abstract:: Seed germination sensu stricto is defined as the physiological events before the radicle tip ruptures the covering tissues. The ability of the radicle to elongate (or germination potential) is observed in developing embryos prior to completion of seed maturation. When embryos at early developmental stages, such as globular, heart, torpedo...
