[Effects of seed size and drought stress on the growth and physiological characteristics of seedlings].

The effects of seed size and drought stress on the growth and physiological characteristics of seedlings were investigated under shading conditions of a pot experiment in greenhouse. There were four treatments, including 80% field water content (FWC), 60% FWC, 40% FWC, and 20% FWC [CK, light drought stress (LDS), medium drought stress (MDS), and high drought stress (HDS), respectively]. The results showed that leaf area per plant, total dry mass, and root-shoot ratio of seedlings regenerated from large seeds (3.

Short-term effect of a negative colonoscopy in patients with functional constipation.

The yield of colonoscopy for neoplasia among patients with chronic constipation is very low. However, a negative colonoscopy may benefit these patients by decreasing anxiety and thereby alleviating constipation symptoms. We performed a prospective study to characterize the effect of a negative colonoscopy in patients with functional constipation.

Effects of seed traits and seed production on the seed predation and dispersal behavior of rodents.

To deeply understand the foraging behavioral strategies of the rodents in response to seeds of different sizes and tannin contents under different seed densities and its relationship with plant regeneration, field experiments were conducted to explore the effects of artificial seeds of different sizes (large and small) and tannin (T) contents (0%T, 2%T, 8%T, and 15%T) on seed predation and dispersal behavior of rodents during simulated non-mast and mast seeding year in Larix principis-rupprechtii plantation of Liupan Mountains in Ningxia. The results showed that seeds were consumed rapidly by rodents in non-mast seeding year but relatively slow in mast seeding year. No significant difference of in situ predation rate (ISPR) was observed between non-mast and mast seeding year.
