Testing SiteFarm

Making Changes

Fruits and Nuts is considering moving its website from the ColdFusion service offered by ANR IT to SiteFarm provided by UC Davis IET. SiteFarm is built on Drupal 8, an open-source content management system written in PHP. This move has several advantages to it, the most important being the continuous security update and feature additions Drupal receives compared to ColdFusion. Check out Drupal's website for more information.

Improvements

  • SiteFarm is designed from the ground up to work as well on mobile devices as on a traditional computer screen
  • Better design: SiteFarm pages look modern, sleek, and ready for the future

Plums

plumsWho doesn't like plums? I sure do. Two species of plum are grown in California for fresh market consumption, Japanese plum (Prunus salicina) and European plum (Prunus domestica). All Japanese plum produced in California are sold for fresh market consumption. Only 2-3% of European plums* are sold as “sugar plums” for fresh markets, and the rest are dried as prunes (Day and Buchner 2012). Japanese plum (Prunus salicina) originated in China and was domesticated in Japan about 400 years ago. United States commercial cultivation began in the 1870’s in California (LaRue 1973). Currently, ninety five percent of domestic fresh plums are grown in California. Currently, ninety five percent of domestic fresh plums are grown in California. In 2014, 105,000 tons were produced on  20,000 California acres, a crop valued at $68,475,000. (Note: this does not include 50,000 acres of prunes.) Most plum production occurs in Tulare and Fresno counties within the San Joaquin Valley. Most plum production occurs in Tulare and Fresno counties within the San Joaquin Valley (USDA 2014).

Plum trees thrive in California’s Mediterranean climate with mild winters and hot, dry summers. Trees grow best in deep sandy loam soils with good drainage, but are tolerant of a wide range of soils. Plum flowers are morphologically similar to peach (perigynous anatomy) with white petals and smaller size (Rieger no date). Flowers and fruit are borne laterally on spurs, although a small number of flowers may be produced laterally on long shoots (see Pollination section for more information). These fruiting spurs live longer than almonds but not as long as apple spurs. For the details of flower anatomy, see Flower Anatomy & Pollination (under Orchard Management), in particular, the Summary Chart: Floral Biology & Pollination.
