Table 1. Variations in trichome density, stomatal pore size, and stomatal density of Astragalus membranaceus leaves subjected to different water conditions over seven weeks.

Treatments	Trichome Density(No./mm2)	Stomata
		Pore size(μm)	Density(No./mm2)
C	15.1 ± 8.2 b	5.1 ± 1.6 a	301.9 ± 59.5 a
T1	36.7 ± 6.0 b	4.5 ± 1.1 b	252.0 ± 47.3 b
T2	39.3 ± 16.9 a	3.5 ± 0.8 c	234.6 ± 42.2 c

Data were analyzed using Tukey’s HSD test. Values are expressed as mean ± SD (n = 8 for trichomes and n = 20 for stomata). Means sharing the same letters are not significantly different (p < 0.05). Note: C represents field capacity; T1 represents 50~55% of available soil water content; and T2 represents 20~25% of available soil water content.
