[Changes of growth and yield characters of five varieties (lines) of tea-applied chrysanthemum under different planting dates and pinching patterns].

To identify the high yield planting date and pinching pattern, we compared the yields of five new varieties (lines) of tea-applied chrysanthemum, the ‘Suju 10’, ‘Suju 12’, ‘Suju 13’, ‘CH1-44’ and ‘CH5-13’. A field experiment with split-split plot design was carried out. The main plot treatments including three (early, middle and late) planting dates, split-plot treatments including 5 new varieties (lines), and split-split-plot treatments including four different kinds of pinching schemes.

[Effects of crude toxin from Alternaria alternata on the growth and physiological metabolism of chrysanthemum 'Jinba' seedlings].

The chrysanthemum black spot caused by Alternaria alternata significantly reduced the quality and yield of chrysanthemum. The crude toxin secreted by A. alternata in the metabolic process have elopathic effects on plants, which is the main pathogenic factor for the occurrence of chrysanthemum black spot.

Identification of PA28β as a potential novel biomarker in human esophageal squamous cell carcinoma.

Esophageal squamous cell carcinoma (ESCC) is one of the most common and serious malignancies in China. However, the exact mechanisms of tumor formation and progression are unclear. As late diagnosis and poor therapeutic efficacy result in lower survival rates, identifying biomarkers for early detection, prognostic evaluation, and recurrence monitoring of ESCC is necessary.

Identification of chrysanthemum (Chrysanthemum morifolium) self-incompatibility.

There has been a heated argument over self-incompatibilityof chrysanthemum (Chrysanthemum morifolium) among chrysanthemum breeders. In order to solve the argument, we investigated pistil receptivity, seed set, and compatible index of 24 chrysanthemum cultivars. It was found that the 24 cultivars averagely had 3.

Factors affecting quantity of pollen dispersal of spray cut chrysanthemum (Chrysanthemum morifolium).

Background: Spray cut chrysanthemum is a vital flower with high ornamental value and popularity in the world. However, the excessive quantity of pollen dispersal of most spray cut chrysanthemum is an adverse factor during its flowering stage, and can significantly reduce its ornamental value and quickly shorten its vase life. More seriously, excessive pollen grains in the air are usually harmful to people, especially for those with pollen allergies.

Factors influencing fecundity in experimental crosses of water lotus (Nelumbo nucifera Gaertn.) cultivars.

Background: Breeding programs for the water lotus (Nelumbo nucifera) are hampered by an inability to account for variation in seed set associated with crosses between different cultivars. We studied seed set in two reciprocal crosses between lotus cultivars ('Guili' × 'Aijiangnan' and 'Molingqiuse' × 'Qinhuaiyanzhi') to obtain insights into factors that govern fecundity in these experimental hybrids. Pollen viability, stigma receptivity and embryo development were compared for each hybrid and reciprocal cross.

Pollen viability, pistil receptivity, and embryo development in hybridization of Nelumbo nucifera Gaertn.

Seed set is usually low and differs for different crosses of flower lotus (Nelumbo nucifera Gaertn.). The reasons remain unknown, and this has a negative impact on lotus breeding.

Effects of CO(2) enrichment on growth and development of Impatiens hawkeri.

The effects of CO(2) enrichment on growth and development of Impatiens hawkeri, an important greenhouse flower, were investigated for the purpose of providing scientific basis for CO(2) enrichment to this species in greenhouse. The plants were grown in CO(2)-controlled growth chambers with 380 (the control) and 760 (CO(2) enrichment) μmol · mol(-1), respectively. The changes in morphology, physiology, biochemistry, and leaf ultrastructure of Impatiens were examined.

[Application of spiral CT 3D reconstruction of rib fracture in clinical forensic practice].

Objective: To assess the clinical application of spiral CT 3D reconstruction in forensic diagnosis of rib fracture.

Methods: Thirty-five cases of rib fractures were collectively studied by X-ray, regular CT scan, and adoptive 3D reconstruction with spiral CT.

Results: Clear and stereoscopic images of rib fractures without interference of the surrounding soft tissue were obtained in all of 35 cases examined.
