Effects of 5-aminolevulinic acid (ALA) on photosynthetic characteristics of tomato grown under suboptimal conditions were investigated to evaluate the potential value of ALA spraying in vegetables. Th...
Heating costs have become a problem for greenhouse tomato production because of the rapid increase in fossil fuel prices in recent years. To reduce fuel consumption without decreasing crop yields, it ...
Ascorbic acid content is an important factor in spinach (Spinacia oleracea L.) quality. In this study, we investigated the effects of the amount of solar radiation and temperature on the ascorbic acid...
‘Le Lectierpears treated with low-temperature (refrigerated storage) at 2–3°C for 0, 10, 30, 60, or 90 days after harvest showed changes in elasticity index, flesh firmness, fresh weight, peel color...
Effects of day and night temperatures and shading on the development of ovules and pea pods (Pisum sativum L. ‘kishu-usui’) were investigated during the entire winter cropping season. Percentages of u...
Effects of low light intensity due to shading during high and low temperature seasons on the flower-bud appearance and fruit setting of the parthenocarpic tomato ‘Renaissance’ were examined.
Effect of root zone temperature on bolting of Japanese bunching onion (Allium fistulosum L.) was investigated using a root zone temperature controlling apparatus. High root zone temperature promoted t...
Effects of air temperature and humidity in the greenhouse on the growth of semi-forced cucumber ‘Natsunokaori’. Air temperature of 30°C and 60% relative humidity promoted the development of fruit and ...
The temperatures of the head leaves of cabbage in a field can be higher than the air temperature during the day due to solar radiation. The decrease in freezing tolerance by solar radiation was confir...
The ralation between a temperature rise in the head leaves due to solar radiation and deacclimation was studied in a field using winter cultivated cabbages on 24 February 1997. The day was clear and t...
Effects of air temperature and humidity in the greenhouse on the growth of the fall-cropped cucumber ‘Natsunokaori’ were investigated. In pinching and wire-training cultivation, air temperature of 30 ...
The relationship between the sugar and vitamin C contents in spinach (Spinacia oleracea L) and komatsuna (Brassica campestris L) and the maximum, minimum and mean air temperatures during the cultivati...
Since the seeds of rootstock ‘Torero’ for eggplant have a poor germination rate, the effects of priming processing using some promoting chemicals, such as polyethylene glycol solution, were studied. W...
Bulbs of Allium caeruleum were stored at 5°C for 0, 3, 6, 9 or 12 weeks from 20 September, then planted in plastic containers in a greenhouse kept at min. 10°C or 15°C. None of the bulbs flowered when...
Mizunasu’ eggplants were grown in heated plastic houses kept at the minimum air temperature of 14°C, 16°C and 18°C. At 14°C, low temperature injuries were observed and marketable yield was remarkably ...
