abstract an investigation was accomplished during 2007 and 2008 to test effect of hormonal treatment and cutting position on rooting of sebri , shekari and natanz cultivars of pear (pyrus pyrifolia.) the experimental design was a two way factorial in a completely randomized method and with pgr5 treatment (iba and iba with naa in four levels in the first year and four higher levels of iba in sec...

There is convincing evidence for the benefits of deep rooting, especially in relation to drought resistance (Lopes & Reynolds, 2010; Uga et al., 2013). Modelling has shown that greater root depth allows increased water uptake and higher yields (Lilley & Kirkegaard, 2011). Deep rooting is thought to be improved by combinations of traits that confer steeper growth and an ability to penetrate stro...

EFFECTS OF CARBON DIOXIDE ENRICHMENT AND IRRADIANCE ON EX VITRO ROOTING, ACCLIMATIZATION AND SUBSEQUENT GROWTH OF MICROPROPAGATED APPLE AND BLUEBERRY. Marvin Pritts and Dorcas Isuta*, Cornell University, Fruit and Vegetable Science Department. 134A Plant Science Building, Ithaca, NY 14850 Previous findings reveal that rooting and acclimatization of apple and blueberry plants is often difficult ...

Duplication-Transfer-Loss (DTL) reconciliation is a powerful and increasingly popular technique for studying the evolution of microbial gene families. DTL reconciliation requires the use of rooted gene trees to perform the reconciliation with the species tree, and the standard technique for rooting gene trees is to assign a root that results in minimum reconciliation cost across all rootings of...

According to EU legislation pigs must have access to rooting material, and the aim of the study was to quantify growing pigs’ preferences among six different rooting materials. The relative attractiveness of six rooting materials was assessed in an operant conditioning set-up using concurrent schedules of reinforcement. Twelve pigs were tested with all six combinations of the reference material...

Wild pigs were established around coastal Spanish settlements in California in the 1800s and expanded over the last century by hunting introductions, domestic releases, and natural dispersal. The current distribution of wild pigs is closely associated with oak woodlands where foraging and rooting by the species may impinge on many native species. Rooting disturbance by wild pigs may be especial...

Micropropagation of Kainth using nodal explants was carried out in tissue culture laboratory, Department of Fruit Science, Punjab Agricultural University, Ludhiana during 2011-13. The effect of various media {1/2 MS (M1), MS (M2) and WPM (M3)} and growth regulators (BAP, IBA and NAA) on establishment, proliferation and rooting was studied. Per cent necrotic culture was found to be influenced by...

These Most agricultural systems in the San Luis Valley of south-central researchers used the previous 1.10 version of NLEAP Colorado include rotations that have crops with different rooting that was capable of simulating the effect of management depths. The previous version of Nitrate L...

Testing of candidates as clones would greatly benefit breeding of Scots pine (Pinus sylvestris L.), but has not been applied because of vegetative propgation of the species is difficult. With a common interest in Scots pine breeding, forest research institutions from Sweden, Finland, and Latvia (Skogforsk, Metla, and Silava, respectively) joined in a collaborative project to develop pine cuttin...
