K E Cushman
The role of ethylene in the development of constant-light injury of potato (Solanum tuberosum L.) and tomato (Lycopersicon esculentum Mill.) was investigated. In one study, silver thiosulfate (STS) was applied to the foliage of four potato ...
Yield and seed oil content response of dwarf, rapid-cycling Brassica to nitrogen treatments, planting density, and carbon dioxide enrichment [0.03%]
氮素供应、种植密度和二氧化碳浓度增加对矮小、快速繁殖甘蓝型油菜产量及籽仁含油量的影响
J Frick,S S Nielsen,C A Mitchell
J Frick
Effects of N level (15 to 30 mM), time of N increase (14 to 28 days after planting), and planting density (1163 to 2093 plants/m2) were determined for crop yield responses of dwarf, rapid-cycling brassica (Brassica napus L., CrGC 5-2, Genom...
Effect of chilling on the gravitropic response of 'Poinsett 76' cucumber (Cucumis sativus L.) radicles [0.03%]
冷害对红籽黄瓜品种(Poinsett 76)胚根向重力反应的影响
A Rab,M E Saltveit
A Rab
Germinating 'Poinsett 76' cucumber (Cucumis sativus) seeds are chilling sensitive, and subsequent radicle elongation is inhibited by exposure to nonfreezing temperatures below 10 degrees C. Reorienting germinated seeds with 5-mm-long radicl...
The Minitron system for growth of small plants under controlled environment conditions [0.03%]
一种在控制环境下培育小型植物的Minitron系统

C P Akers
The design and operation of a system is described in which small plants can be grown under controlled environment conditions. Important features of this "Minitron" system include precise control of temperature and CO2 concentration in a flo...
Effects of relative humidity and root temperature on calcium concentration and tipburn development in lettuce [0.03%]
相对湿度和根部温度对生菜钙浓度及叶尖端褐变的影响

Benzimidazoles are effective and widely used fungicides, but they may be phytotoxic. We studied the effects of a single drench application of six benzimidazoles and one acetanilide fungicide on photosynthetic gas exchange, growth, developme...
Growth and photomorphogenesis of pepper plants under red light-emitting diodes with supplemental blue or far-red lighting [0.03%]
在不同蓝光或远红光补充下的红色LED对辣椒生长和形态产生的影响
C S Brown,A C Schuerger,J C Sager
C S Brown
Light-emitting diodes (LEDs) are a potential irradiation source for intensive plant culture systems and photobiological research. They have small size, low mass, a long functional life, and narrow spectral output. In this study, we measured...
Tomato growth as affected by root-zone temperature and the addition of gibberellic acid and kinetin to nutrient solutions [0.03%]
根区温度及赤霉素和6-苄氨基嘌呤对番茄生长的影响
B Bugbee,J W White
B Bugbee
The effect of root-zone temperature on young tomato plants (Lycopersicon esculentum Mill. cv. Heinz 1350) was evaluated in controlled environments using a recirculating solution culture system. Growth rates were measured at root-zone temper...
Effects of artificial enclosure of young lettuce leaves on tipburn incidence and leaf calcium concentration [0.03%]
人工遮蔽对生菜叶片尖端烧伤及叶柄钙素浓度的影响
D J Barta,T W Tibbitts
D J Barta
The young developing leaves of 20-day-old lettuce plants (Lactuca sativa L. 'Buttercrunch') were enclosed by aluminized polyethylene sheaths to decrease transpiration and reduce Ca transport. The plants were grown in recirculating solution ...
Growth reponses of eggplant and soybean seedlings to mechanical stress in greenhouse and outdoor environments [0.03%]
温室及室外环境中的机械刺激对茄子和大豆幼苗生长的影响
