Culturing excised root tips proves good model for early detection of salt stress

A study examined degrees of salt stress tolerance in species of the genus Prunus. Researchers studied the responses of isolated roots to salt stress in vitro in controlled culture conditions. Among other findings, the team discovered a significant inverse correlation between salt tolerance and starch accumulation in the maturation zone of root tips. The authors recommend the use of excised root cultures for rapid, early detection of salt stress tolerance in plants.

Darwin string thinner thins peach trees at bloom, drum shaker effective for green fruit

New research showed that a Darwin string thinner can effectively thin peach trees at bloom stage. Trials using trees trained to a perpendicular V system showed that a Darwin string thinner at 60% to 80% full bloom reduced crop load on scaffold limbs by 21% to 50% compared with a hand-thinned control. The study also reported that a spiked drum shaker can thin at bloom or at the green fruit (pit hardening) stage.

Pest infestation correlated to some high-quality fruit traits

Swiss scientists evaluated the relationship between insect resistance and apple fruit quality. The study used 250 progeny apple plants to relate fruit traits to infestation by major insect pests. Infestation by codling moth and green apple aphid was correlated to some quality-determining fruit traits, whereas infestation by other major apple herbivores was not related to the fruit traits. The results emphasized the need to consider pest resistance when breeding for high quality apple cultivars.

Researchers recommend best practices for commercial production in water-limited regions

Marketable yield, yield components, quality, and phenolic compounds of artichoke heads were investigated in response to three irrigation regimes and four nitrogen rates under subsurface drip irrigation. Results showed that irrigation was more effective than N management for optimizing artichoke yield. Time of harvest had the largest effect on artichoke nutritional quality, followed by deficit irrigation. The study will help introduce artichoke cultural practices into commercial production in water-limited regions of the southern United States.
