In four experiments the major effect on ̄owering was that of temperature. Temperatures applied between 2 October and 20 February in ̄uenced the time of ̄owering of D. allwoodii, `Doris', while in D. alpinus, `Pike's Pink', temperatures applied over a longer period between 2 October and 11 March in ̄uenced the time of ̄owering. Keeping stock plants at low temperatures, before cuttings were taken, ...

In vitro shoot multiplication of Merton I. 793, a clonal apple rootstock, was achieved through terminal/axillary bud culture using Murashige and Skoog (MS) basal medium supplemented with 0.5-1.0 mg/L 6-benzyl amino purine (BA) and 0.1 mg/L indole-3-butyric acid (IBA). Time of collection of explants, duration of surface sterilents and growth regulators added in the medium influenced the survival...

Malus hupehensis is an excellent Malus rootstock species, known for its strong adverse-resistance and apomixes. In the present study, stem cuttings of M. hupehensis were treated with three types of exogenous hormones, including indole acetic acid (IAA), naphthalene acetic acid (NAA), or green growth regulator (GGR). The effects and mechanisms of exogenous hormone treatment and antioxidant enzym...

I explore the origins of the unphysical predictions from rooted staggered fermion algorithms. Before rooting, the exact chiral symmetry of staggered fermions is a flavored symmetry among the four "tastes." The rooting procedure averages over tastes of different chiralities. This averaging forbids the appearance of the correct 't Hooft vertex for the target theory.

N ov. 22, 2009, marked a significant milestone for Tamar Abell. It was the end of a 10-year ordeal that cost her family’s skilled nursing facility business more than $2 million in settlement costs and legal fees, not to mention numerous sleepless nights and hundreds of hours of paperwork. It began in the spring of 2000: After three decades of successfully owning and operating nursing facilities...

introduction: potential almond rootstock and thus main genetic sources for the breeding of its new rootstocks are almond itself, peach and plum, and these species cross-breeds almond is a source of resistance to limestone and to drought because of its roots, which reach deep layers of soil; it is also more resistant than peach to na and bo. asexual or vegetative propagation is a hereditable cha...

This study was designed to examine the effects of promoting substances on bud retention, rooting and plantlets survival of rooted cuttings on selected tree species using growth promoting substances. Stem cuttings were treated with rooting-promoting substances, planted in plastic pots filled with top soil and arranged using a completely randomized design (CRD) in a screen house. Stem cuttings of...

Phylogenetic rooting experiments demonstrate that two chloroplast genes from commelinoid monocot taxa that represent the closest living relatives of the pickerelweed family, Pontederiaceae, retain measurable signals regarding the position of that family's root. The rooting preferences of the chloroplast sequences were compared with those for artificial sequences that correspond to outgroups so ...

BACKGROUND AND AIMS The evolution of complex rooting systems during the Devonian had significant impacts on global terrestrial ecosystems and the evolution of plant body plans. However, detailed understanding of the pathways of root evolution and the architecture of early rooting systems is currently lacking. We describe the architecture and resolve the structural homology of the rooting system...
