Cell walls of asparagus after harvest.

Asparagus (cv. Limbras 10) spears were harvested and stored in perforated plastic bags for 2-72 h at room temperature. The data suggest that wall accumulation (particularly pectin) continues to occur during the first 24 h after harvest. Some fluctuation in molecular weights of wall polysaccharides also occurs over this time, primarily of pectin in the tip of the spear and hemicellulose (including xyloglucan) in the main axis of the spear. It is suggested that harvest-related changes in asparagus cell walls are initially manifest as a slowing down and eventual cessation of wall accumulation, rather than extensive wall breakdown. This response tends to reflect the immature nature of the spear at harvest, and suggests that textural deterioration seen after harvest is not, initially at least, linked to wall integrity.
