The stockpiled forage canopy consists of tillers at different ages, which have specific development patterns. objective was to understand the Urochloa brizantha cv. Marandu during stockpiling period, by morphogenic evaluation ages. experiment conducted in a completely randomized design, split plot scheme, with four replications. Three ages (young, mature and old) two periods (initial final) wer...

A delay in the mechanical transplantation (MT) of rice seedlings frequently occurs in Huanghuai wheat-rice rotation cropping districts of China, due to the late harvest of wheat, the poor weather conditions and the insufficiency of transplanters, missing the optimum transplanting time and causing seedlings to age. To identify how delaying transplanting rice affects the agronomic characteristics...

We analysed the CAG repeat length in exon 1 of the androgen receptor gene in 59 idiopathic Japanese infertile males with oligozoospermia; 36 fertile males were also analysed as controls. The number of CAG repeats in infertile males ranged from 14 to 32 (mean 21.2+/-4.2), whereas the number of CAG repeats in fertile males ranged from 16 to 31 (mean 21.4+/-3.5). Among infertile males, six possess...

Superior plant architecture is a key means of enhancing yield potential in high yielding varieties. A newly identified recessive gene, named sd-c, controls plant height and tiller number. Genetic analysis of an F2 population from a cross between the semi-dwarf mutant and japonica cv. Houshengheng showed that the sd-c locus was flanked by SSR markers RM27877 and RM277 on chromosome 12. Thirty ni...

More efficient resource use, especially nitrogen (N) in agricultural fields could considerably reduce the losses and spillover effects on environment. Cereal-legume mixtures can lead to more uptake of growth-limiting resources, increase stabilize yields, due variation functional traits that facilitate partitioning niche space. Here we identify crop with optimal N use two selected cereal-legume ...

BACKGROUND This article analyzes several key issues in the debate: the acceptability of in vitro fertilization; regulation of assisted reproduction and the possibilities of reimbursement for assisted reproduction treatment in Lithuania. METHOD Two groups of respondents participated in the survey: fertile women and women with fertility disorders. 93 completed questionnaires from women with fer...

Tillering (branching) is a major yield component and, therefore, a target for improving the yield of crops. However, tillering is regulated by complex interactions of endogenous and environmental signals, and the knowledge required to achieve optimal tiller number through genetic and agronomic means is still lacking. Regulatory mechanisms may be revealed through physiological and molecular char...

Article info: Received: 30 April 2014 Accepted: 29 January 2015 ABSTRACT The trial was carried during 2011-2013 on the second experimental field of the Institute of Forage Crops – Pleven, Bulgaria. Eight generations (P1, P2, F1, F2, RC1 and each reciprocal generation) from a cross between the Shtambovii and Pleven 10 varieties were sown in this study. Five traits were evaluated: number of pods ...
