LONDON, Oct. 12, 2016 /PRNewswire/ -- Photosynthesis is one of the plant relatively sensitive physiological metabolism reaction to salt stress. This experiment took two cucumber varieties Zhongnongda22 and Deltastar with different sensitiveness to salt stress as materials to study photosynthetic responses to salt stress.
The effects of cultured trough size (transaction width×depth is 20 cm×10 cm, 20 cm×15 cm, 20
cm×20 cm) and pot volume (diameter: 12 cm, height: 10 cm, volume: 1 L) on plant growth and development, water and fertilizer uptake and use, yields and quality of elevated cultivation of tomato (lycopersicon
esculentum mill.) were studied with the elevated closed-cycle cultivation system.
In order to study the effects of plant growth promoting rhizobacteria HG28-5 on cucumber growth and its rhizosphere microecology, this experiment sowed the cucumber seeds in trays after soaking them in HG28- 5 suspension. The quotas of emerging and seedling growth were examined to confirm its promotion effects on cucumber growth.
In order to definite a new disease observed on carrot roots and its pathogen species of Fusarium causing carrot root rot, this paper isolated the pathogen with tissue isolation method, inoculated the carrot slices, and carried out pathogenicity identification with morphology and molecular biology.
In order to clear the control effect of chemical prevention on tomato chlorosis virus (ToCV) disease and sift out chemical pesticides, the control effect of controlling Bemisia tabaci biotype Q by chemical pesticides were evaluated and the control effect of virus inhibitors on ToCV disease were conducted through field trial and PCR detection in the lab.
In order to explore the transformation of the production mode, and achieve high yield and high efficiency of corn, researchers analyzed the relationship between the increases of planting density and yield of corn, present situation of planting density and yield increasing effects of increasing planting density in different areas, and advantages of grain mechanical harvest technique.
Gibberellin (GA) plays an important role in plant growth and development. This paper reviews the research progresses made in the regulating mechanism of GA on tuber morphogenesis in higher plant.
Cold stress is one of the most important limited factors that affect the growth and development of crops. A series of complex morphological, physiological and molecular changes have been made in order to adapt and resist the low temperature stress.
In order to select high-quality oats cultivars suitable for the irrigation area of Ningxia Hui Autonomous Region and enrich forage grass resources in the region, 11 oat cultivars from abroad were grown in Pingji Fort area of Ningxia.
The effect of fenaminstrobin·difenoconazole·thiamethoxam 45% FSC on winter wheat emergence, plant quality, the main diseases and insect pests control effect and yield was studied in field experiment with Zhoumai27 as tested variety.
