Crop sensitivity to root zone salinity can vary over time, which lead severe damage when high coincides with soil salinity. The variation in of sunflower during its growth cycle is unknown. Two pot experiments were conducted sand culture a complete nutrient solution. Solutions flushed through pots excess maintain specified salt concentrations the In Experiment 1, salt-sensitive stages determine...

This study documents the flowering phenology and its potential consequences on a nursery pollination mutualism between a dioecious plant, in which honest male plants, but not cheating females, allow the specific pollinator to reproduce within inflorescences. Very few pollinators were found to emerge during plant anthesis, leading to a low (if any) potential benefit through pollen dispersal. Thi...

The frequency of heat events is likely to increase due global climate change, posing an increasing risk wheat production. To optimize crop management strategies for coping with future climates, it crucial quantify the high-temperature occurrence during cropping seasons. Here, sixty-six years (1955~2020) meteorological data reproductive growth were collected from six stations in Huaibei Plain An...

Plant breeding based on grain yield (GY) is an expensive and time-consuming method, so new indirect estimation techniques to evaluate the performance of crops represent an alternative method to improve grain yield. The present study evaluated the ability of canopy reflectance spectroscopy at the range from 350 to 2500 nm to predict GY in a large panel (368 genotypes) of wheat (Triticum aestivum...

Climatic warming is often predicted to reduce wheat yield and grain quality in China. However, direct evidence is still lacking. We conducted a three-year experiment with a Free Air Temperature Increase (FATI) facility to examine the responses of winter wheat growth and plant N accumulation to a moderate temperature increase of 1.5°C predicted to prevail by 2050 in East China. Three warming tre...

Plastic film mulching often increases the yield of winter wheat in Loess Plateau China, but physiological mechanisms are unclear, especially response to interaction between mulch and water supply. In this study, we investigated interactive effects initial soil (dry, moderate, wet), cover (plastic mulch, bare soil), seasonal conditions on dynamics dry matter partitioning, water-soluble carbohydr...

the aim of this experiment was the study of dry matter and nitrogen (n) accumulation, remobilization and harvest index in different wheat cultivars. five bread wheat cultivars (darya, kuhdasht, shiroudi, tajan and zagros) and two durum wheat cultivars (arya and dena) were studied under optimum growth conditions during 2008-2009 at research field of gorgan university of agricultural sciences and...

The effects of maize (Zea mays L.) phenology on establishment and adult emergence of the western corn rootworm (Diabrotica virgifera virgifera LeConte) and plant damage to maize was evaluated in field trials in 2001 and 2002 and in the greenhouse. Although neonate western corn rootworm larvae were able to initially establish on maize roots during anthesis and early reproductive stages, these ol...
