Second Year Recovery of Hedgerow Walnuts from Sustained Deficit Irrigation
Hedgerow walnuts (cv. Chico) that were irrigated at 33 and 66% ETc from 1986-88 suffered marketable nut yield reductions of 32 and 50%. Upon returning these trees to full irrigation in 1989, tree growth and.water relations immediately recovered but yields were little changed. Harvest yields completely recovered this year (after two years of full irrigation). This indicates that hedgerow walnuts...
متن کاملA Leaf Lamina Compression Method for Estimating Turgor Pressure
A portable wiltmeter instrument to estimate leaf turgor pressure according to an adaptation of the flattening method was developed. In the instrument, a flexible inflating membrane presses the leaf against a flattening plate having small orifices surrounded by a finely engraved network of obtuse indentations through which air flow is delivered. During a measurement, as the compression builds up...
متن کاملSap Flow Response to Olive Water Stress: a Comparative Study with Trunk Diameter Variations and Leaf Turgor Pressure
The aim of this work was to evaluate the potential of used sap flow (SF), trunk diameter variation (TDV) and leaf turgor (LT) sensors for assessing water stress in a ‘Arbequina’ hedgerow olive orchard with 1667 trees ha. Measurements were made in control trees irrigated to replace 100% of the crop water needs, and in trees under two regulated deficit irrigation strategies, 60RDI and 30RDI, in w...
متن کاملThe impact of prolonged flood-irrigation on leaf gas exchange in mature pecans in an orchard setting
Woody perennials subjected to root oxygen-stress often respond with varying levels of reduced assimilation and leaf gas exchange. Yet in most of these studies, seedlings grown in pots were subjected to experimental conditions that rarely exist in nature for mature trees. To determine if flooding mature orchard-grown pecan (Carya illinoiensis (Wangh) K. Koch) results in a similar depressed photo...
متن کاملOlive (Olea europaea L.) leaf extract prevents motor deficit in streptozotocin-induced diabetic rats
Introduction:Olive leaves have been recommended in the scientific literature and traditional medicine as a cure for the treatment of diabetes and this plant has powerful antioxidants and neuroprotective effects. Here, we studied the possible effects of olive leaf extract (OLE) on motor deficits in diabetic neuropathy. Methods:The rotarod treadmill test was used to access motor coordination...
