Apple Fruit Growth and Maturity are Affected by Early Season Temperatures

P138: Are Depression and Anxiety Affected by Adenosine A2A Receptors?

Adenosine acts as neuromodulator in the brain, which its involvement in a wide range of brain processes and diseases has been studied, such as epilepsy, sleep, anxiety, panic disorder, Alzheimer’s disease, Parkinson’s disease and schizophrenia. Adenosine receptors have been detected: A1R, A2AR (A2AR), A2BR, and A3R. A1R and A2R inhibit cAMP production, while A2AR and A2BR stimulate cAMP product...

Apple Maturity Discrimination and Position

The most crucial problem of apple harvesting robot is to get the exact location and the maturity degree of the target. A system of apple maturity discrimination and positioning based on the multi-spectral technology and laser triangulation ranging principle is researched. Signal transmission, signal reception, signal processing, the CPU processing and several PC components are involved in the s...

Shade effects on growth, flowering and fruit of apple

Light is a critical resource needed by plants for growth and reproduction. A major portion of the apple (Malus x domestica Borkh.) tree’s canopy is subjected to shade during most daylight hours each day and such shade may affect productivity. The current research determined effects of morning, afternoon, and all-day shading on processes that are significant to orchard productivity. In 1996 ‘Gin...

Early-season predation on aphids by winter-active spiders in apple orchards revealed by diagnostic PCR.

Aphids are major pests in apple orchards, debilitating the crop and spreading disease. We investigated whether early-season predation by canopy spiders may be effectively controlling aphid numbers in three organic orchards. For this purpose, we monitored the aphid population dynamics from the winter eggs to colony stages and compared this to spider abundances and rates of predation on aphids de...
