A disorder caused in the field and is related to climactic conditions, variety selection and mineral nutrition. Leaves with tipburn are unsightly and the damaged leaf margins are weaker and susceptible to decay. Ethylene injury. Due to exposure to low concentrations of ethylene gas which stimulates the production of phenolic compounds which in turn leads to brown pigments. Russet spots appear as dark brown spots especially on the midribs. Under severe conditions, russet spots are also found on the green leaf tissue and throughout the head.

The disorder is strictly cosmetic but makes the lettuce unmarketable. Ethylene contamination may occur from propane fork lifts, transport in mixed loads, or storage with ethylene-generating fruits such as apples, pears, etc. Brown Stain. The symptoms of this disorder on romaine lettuce heads are yellowish-reddish-brown large, depressed spots or stains. These are most noticeable on the midribs, and may darken and enlarge with time.

Visual symptoms of brown stain may occur less rapidly on Romaine than on iceberg lettuce. Pink rib. A disorder associated with heads that are overmature. Higher than recommended storage temperatures can also lead to a increased incidence of pink rib. In this disorder, the midribs take on a generalized pinkish coloration. Ethylene exposure does not appear to affect pink rib and low O 2 atmospheres do not control it.

Breakage of the midribs often occurs during field packing, especially on overmature romaine heads, and results in unsightly browning and increased susceptibility to decay. Product harvested early in the morning, when pulp temperatures are lower, is more susceptible to midrib cracking and breakage.
