So the seedlings in the egg carton are fighting a serious uphill battle right from the start. In cucumber (Cucumis sativus), high lipoxygenase-1 (LOX-1) activity has been detected in the soluble fraction prepared from cotyledons of germinating seeds, and the involvement of this enzyme in lipid turnover has been suggested (K. Matsui, M. Irie, T. Kajiwara, A. Hatanaka [1992] Plant Sci 85: 23-3 Here are the seedlings in the barely alive egg carton: Here is a top view and side view of a plant just turning sickly. Dip your finger into the soil and check if it is moist or dry. Aphids secreted honeydew coats the leaf and hamper photosynthesis. Cucumber fruit shape is controlled by multiple genes and therefore exhibits quantitative inheritance2. An egg carton is just too shallow. Through our previous work, we discovered that 2 days post-anthesis (DPA) was the key time point at which various phenotypic and genotypic characteristics of cucumber fruits are determined. Help!
