BACKGROUND AND AIMS Previous studies have reported effects of pollen source on the oil concentration of maize (Zea mays) kernels through modifications to both the embryo/kernel ratio and embryo oil concentration. The present study expands upon previous analyses by addressing pollen source effects on the growth of kernel structures (i.e. pericarp, endosperm and embryo), allocation of embryo chem...
for sexual reproduction of allium hirtifolium, collected bulbs were planted in the field. in order to develop ovary embryo and seed setting, control self-pollination and natural open pollination took placed using honey bees under cages. ovary development and seed setting of a. hirtifolium extraordinary were affected by pollination and there was a significant difference between mean effect of se...
OBJECTIVE This investigation assessed the effect of serum estradiol levels on outcomes of in-vitro fertilization and embryo transfer (IVF) cycles. MATERIALS AND METHOD This was a retrospective cohort study of 1123 IVF cycles comparing impact of estradiol (E(2)) levels on follicular development, fertilization, embryo quality, implantation, pregnancy rate, miscarriage rate, and selected obstetr...
Aim: This study was conducted to explore the effect of serum anti-Mullerian hormone (AMH) level on in vitro fertilization (IVF) cycle outcomes. Material and Methods: A total 142 patients included this study, were divided into three groups according their AMH levels as Group 1: 5-10 ng/ml (n=108), 2: 10-15 (n=20), 3: >15 (n=14). Demographic characteristics recorded. The duration infertili...
Somatic embryos and plants were produced from mature and immature embryo derived callus of wheat. Immature embryo showed a better capacity for somatic embryogenesis and plant regeneration. Presence of 2, 4-D was shown to be essential for induction and maintenance of somatic embryogenesis. Organic nitrogenous additives (L-proline, L-asparagine and casein hydrolysate) marked an effect on somatic ...
In this paper, we studied polyetheneglycol (PEG) pretreatment effect on the mature embryo culture in vitro by using barley (Hordeum vulgare L.) seeds. Meanwhile, we analyzed and assayed its mineral element and endogenous hormone level. The experimental results were as follows: (1) PEG-6000 imbibition could obviously slow down the water timecourse absorbed by barley seeds; (2) 10% PEG-6000 treat...
