Almond trees grown on peach rootstock initially more productive

Rootstock Options for California Almond Orchards

Nemaguard has been the workhorse rootstock of the California almond industry for many decades. It is well adapted to the well-drained, non-calcareous loam and sandy loam soils common throughout the San Joaquin Valley. Nemaguard is vigorous, immune to rootknot nematode, compatible with all almond varieties, doesn’t sucker much, has decent anchorage and is easy to grow at the nursery. However, th...

Rootstock Effects on Pistachio Trees Grown in Verticillium dahliae-Infested Soil.

ABSTRACT In a field trial in soil infested with Verticillium dahliae, we compared the yield, growth, incidence of symptoms of Verticillium wilt, and mortality of two interspecific hybrid pistachio tree rootstocks (UCBI and PGII) with the standard rootstocks: the V. dahliae-resistant and susceptible Pistacia integerrima and P. atlantica, respectively. After 10 years, the trees were destructively...

Evolutionary Genomics of Peach and Almond Domestication

The domesticated almond [Prunus dulcis (L.) Batsch] and peach [P. persica (Mill.) D. A. Webb] originated on opposite sides of Asia and were independently domesticated ∼5000 yr ago. While interfertile, they possess alternate mating systems and differ in a number of morphological and physiological traits. Here, we evaluated patterns of genome-wide diversity in both almond and peach to better unde...

Alterations in Root Morphology of Rootstock Peach Trees Caused by Mycorrhizal Fungi

mechanism of drought stress tolerance of gf677 rootstock (peach and almond hybride) under in vitro conditions

mechanisms of drought stress tolerance of gf677 rootstock, peach and almond hybrid, (prunus persica × prunus amygdalus) were studied under in vitro conditions. plantlets of gf677 rootstock were subcultured into the murashige and skoog (ms) solid proliferation medium containing 1 mg/l ba (6-benzyladenine) and 0.1 mg/l naa (naphthaline acetic acid) in four drought stress levels 0 (control), 10, 2...
