[Physiological responses and tolerance to drought stress of different watermelon genotypes.].

With the continuous drought stress treatment to 12 pot-grown watermelon genotypes originated from different regions, the influence of drought stress on plant height, root length, fresh mass and dry mass was studied, and the physiological responses of these genotypes to drought stress were compared. Drought resistance of these watermelon genotypes was preliminarily determined according to the drought injury, and then confirmed by membership function evaluation method. We found that the watermelon genotypes exhibited great difference in drought tolerance based on the occurrence of drought injury and the degree of injury severity.

[Effects of soil compaction stress on the growth and nitrogen metabolism of cucumber roots].

Taking cucumber cultivar 'Jinchun 4' as test material, a pot experiment was conducted to study the effects of soil compaction stress on cucumber root growth, respiration rate, activity, and nitrogen metabolism at different development stages. Two treatment were installed, i. e.

[Effects of soil compaction stress on respiratory metabolism of cucumber root].

A pot experiment with cucumber cultivar "Jingchun 4" was conducted to study the effects of soil compaction stress on the respiratory metabolism of cucumber root. Two treatments were installed, i.e.

[Study on treatment of iron-deficiency anemia by shengxuening].

Objective: To observe the therapeutic effect of shengxuening (SXN) in treating iron-deficiency anemia (IDA) and to explore its molecular mechanism on iron metabolism balance regulation.

Methods: Patients with IDA were randomly divided into the treated group and the control group, 50 in each group. They were treated with SXN (0.
