1. The intensified red skin color of Red McClure potatoes, produced by treating growing plants with the sodium salt of 2,4-D at rates of 1/3 and 1 pound per acre, persisted throughout a 6-month storage period. 2. Treatment produced potatoes with a significantly lower average weight of sprouts and with significantly more sprouts than the controls. 3. When… (More)
Treatment of growing Red McClure potato plants with 2,4-D at a rate of one-half pound per acre produces tubers with significantly higher protein content and with a significantly higher specific gravity.
It can therefore be confidently stated that if there are nitrates present in the tubers, the amount is less than 0.1 mg. nitrate per liter or 0.163 per cent potassium nitrate on a dry weight basis. This is much less than the 1.5 per cent toxicity level set for nitrates. Therefore, it can be concluded that Red McClure potatoes, from plants which have been… (More)
Treatment of Red McClure potato plants with low concentrations of the sodium salt of 2,4-D results in an increase of free glutamic acid and a decrease of 11 other amino acids. Possible mechanisms of 2,4-D action have been discussed in relation to these facts.
