Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
70 words
A method of increasing the resistance of plant tissue to damage caused by low temperature comprising applying to the plant tissue surfaces at ambient, non-freezing air temperatures at least about four hours prior to exposure to such low temperatures, not including subfreezing temperatures, an aqueous solution containing an amount of tetrahydrofurfuryl alcohol, tetrahydrofurfuryl amine or mixtures thereof effective to increase the resistance of the plant tissue to such low temperatures.
Claim 2
Independent Claim
70 words
A method of increasing the resistance of plant tissue to damage caused by low temperature comprising applying to the plant tissue surfaces at ambient, non-freezing air temperatures at least about four hours prior to exposure to such low temperatures, not including subfreezing temperatures, an aqueous solution containing an amount of tetrahydrofurfuryl alcohol, tetrahydrofurfuryl amine or mixtures thereof effective to increase the resistance of the plant tissue to such low temperatures.
