In this paper, it is proposed an irrigation control system able to use in an efficient way the water in greenhouses of heterogeneous plants without sacrificing the good condition of them, to accomplish this, firstly it is proposed a clustering of plants based on the irrigation needs and secondly implementation of a genetic algorithm that establishes the optimum watering times and waiting betwee...
Seedlings of Salix eriocephala Michx., Salix sericea Marsh., and their F1 hybrids were tested for their growth under contrasting water conditions. One-year old seedlings were grown in pots and subjected to one of two experiments, a scheduled-watering experiment (watered every 1, 4, 8, or 12 days) or a dry-down experiment (no watering after an initial period without water limitation). In the sch...
AMONG the many signs of hypothyroidism, puffiness of the eye-lids is a familiar feature of the facial appearance, but watering of the eyes is not usually reported as a prominent symptom. Recently we have seen five patients who presented to an oculist complaining of watering of the eyes in whom there was found evidence of hypothyroidism and whose symptoms were relieved by the administration of t...
The aim of present study was to evaluate the effects of drought stress on net photosynthesis rate (Pn), stomatal resistance, water use efficiency (WUE) and biomass (BM) of six maize (Zea mays L.) hybrids. Drought stress applied by withholding water supply at 4-5 leaf stage (S1, vegetative stage), anthesis (S2, reproductive stage), and dual stress condition (S3, combination of vegetative and rep...
Embolism formation and spread are dependent on conduit structure and xylem network connectivity. Detailed spatial analysis has been limited due to a lack of non-destructive methods to visualize these processes in living plants. We used synchrotron X-ray computed tomography (microCT) to visualize these processes in vivo for Juglans microcarpa Berl. saplings subjected to drought, and also evaluat...
Drought stress can seriously affect tuberization, yield and quality of potato plant. However, the precise molecular mechanisms governing potato stolon's response to drought stress and water supply are not very well understood. In this work, a potato (Solanum tuberosum L.) variant, Ningshu 4, was subjected to severe drought stress treatment (DT) and re-watering treatment (RWT) at tuber bulking s...
