浮萍 (Lemna gibba) 在内盖夫沙漠 12 平方米的浅水池塘中种植，从 1984 年 4 月开始连续种植 12 个月。月平均生长速度随一年中的季节变化。最低日产量为 2.6.+-.0.4 g 干重 m-2 day-1，是在 1 月份获得的。 9 月和 5 月获得最高日产量，m-2 day-1 干重为 7.9.+-.2.6 g，m-2 day-1 干重为 7.0.+-.1.2 g。仲夏（7 月）期间产量下降了 35%，4.8 .+-。 1.2 克干重 m-2 day-1。该年的平均率为 5.15.+-.1.7 克干重 m-2 day-1。植物的蛋白质含量为每单位干重 30% 至 38%。生长表现是根据当时的气候条件进行讨论的。
Duckweed, Lemna gibba, was grown in 12 m2 shallow ponds in the Negev desert, during 12 months of continuous cultivation, beginning April 1984. Average monthly growth rates varied with the season of the year. The lowest daily yield, 2.6.+-.0.4 g dry weight m-2 day-1, was obtained during January. Highest daily yields, 7.9.+-.2.6 g dry weight m-2 day-1 and 7.0.+-.1.2 g dry weight in m-2 day-1, were obtained during September and May. A 35% decline of the yield was seen during mid-summer (July), 4.8 .+-. 1.2 g dry weight m-2 day-1. The average rate for the year was 5.15.+-.1.7 g dry weight m-2 day-1. The protein content of the plants ranged form 30 to 38% per unit dry weight. Growth performance is discussed in relation to the prevailing climatic conditions.
