The purpose of this study was to investigate the effect of estrus synchronization to altrenogest regumate (progesterone), PMSG/hCG, and artificial insemination (AI) on galectin-3, FGF-9 gene and protein expression. The morpho-metrical parameters of the endometrium and the number of corpora lutea (CL) were recorded. RNA was isolated from endometrial, oviduct and ovary tissues of non-synchronized (Control; n = 7) and AI synchronized (regumate, PMSG/hCG; n = 7) sows. The total number of CL was higher (P<0.05) in pigs treated with regumate/PMSG/hCG. The content of gelactin-3 and FGF-9 mRNA in pre-embryonic development stages increased on particular days, in control and studied in regumate/PMSG/hCG administered pigs. Gelactin-3 and FGF-9 were affected by regumate/PMSG/hCG treatment in the both pre-embryonic development stages (P<0.001, P<0.05) and encdometrial tissue (P<0.001, P<0.01). The regumate/PMSG/hCG treatment resulted in elevated expression of gelactin-3 (P<0.001) and FGF-9 (P<0.005) in oviduct and ovary tissues in comparison to control sows. Moreover, oviduct amount of gelectin-3 mRNA was higher in regumate/PMSG/hCG sows in comparison to the control group (P<0.05), whereas, expression characteristics of gelactin-3 and FGF-9 were investigated by hematoxylin and eosin stained and immunohistochemical staining. The results showed that galectin-3 and FGF-9 were significantly shown in the endometrium, oviduct and ovary tissues of the regumate/PMSG/ hCG. Presented data show that exogenous hormones administration can affect gene and protein expression in the sow reproductive tract.

The effects of seed soaking treatment with the solutions of plant growth regulators IAA, GA3 and BAP on seed germination and shoot and bulb growth of Allium victorialis var. platyphyllum (Korean wild garlic) were determined. A significant variation in the seed germination rate was recorded at all treatments for various soaking periods. Maximum seed germination was obtained when seeds were soaked in IAA or GA3 solution at 200 mg L-1. The MAP treated seeds started to germinate after 3 months. Among treatments, IAA was found to be most effective in improving seed germination, but further seedling growth was not correlated to the soaking time. Seed soaking in IAA or GA3 solution enhanced further growth of seedlings compared with water control treatment. Shoot and bulb growth was highest in GA3 treatments.

Effects of nitrogen (N), phosphorous (P) and potassium (K) on the shoot and bulb growth of wild garlic (Allium victorialis var. platyphyllum) were studied by adopting in vitro culture. These macronutrients influenced the growth of both the shoot and bulb of garlic depending upon their application doses. A minimum of 3% potassium nitrate (KNO3) as a source of nitrogen was found to be critical for shoot elongation while higher concentrations were inhibitory. Garlic bulb growth was profuse on the usual KNO3 strength and sucrose (7%), followed by KNO3 (9.4 mM) supplement. On providing 41.22 mM ammonium nitrate (NH4NO3) as nitrogen source highest shoot growth was observed while 82.45 mM NH4NO3 as a source of nitrogen supported high bulb growth. With regard to potassium a good shoot growth was observed in medium that contained 0.31 mM KH2PO4 and 3% sucrose, while bulb growth was high on 2.5 mM KH2PO4 and 7% sucrose. These experiments may thus direct the development of excellent growth conditions for the commercial production of edible wild garlic.

This study aims to explore micrometeorological influences on particle growth by the experimental and statistical approaches. Characteristic meteorological conditions of the nucleation event were observed, and turbulence in the PBL seemed to play a role in particle growth. The major micrometeorological factors governing particle size growth in the PBL were instability (-z/L), friction velocity (u*), Bowen ration (B), and downward shortwave radiation (RsDN) as determined by a regression model. This result indicates that the geographical properties including land surface cover and geomorphology have strong influence on the aerosol size growth in PBL.
