Six Iranian accessions of Cucumis melo, including Inodorus, Cantalupensis, and Dudaim groups, were planted and then harvested at two harvesting stages including 21 and 28 days after anthesis for Dudaim group and 28 and 38 days after anthesis for Inodorus and Cantalupensis groups. At the time of harvest, we measured some quality parameters and appearance indices of fruits, such as the number of ...

Barley crop grown in semiarid areas may experience water deficit especially during grain filling that makes them more dependent on stem water-soluble carbohydrates (WSC). Fructans are the most important reserved carbohydrates. A pot experiment was undertaken at Shahid Chamran university in the duration of 2010-2011 growing seasons to investigate the accumulation and loss of WSC and the activity...

To estimate potential impact of climate change on wheat fusarium ear blight, simulated weather for the A1B climate change scenario was imported into a model for estimating fusarium ear blight in central China. In this work, a logistic weather-based regression model for estimating incidence of wheat fusarium ear blight in central China was developed, using up to 10 years (2001-2010) of disease, ...

The concentration of free indoleacetic acid (IAA) is high in cotton (Gossypium hirsutum L.) fruiting forms before anthesis, but is low at and for a few days after anthesis. Amide-linked and ester IAA were measured in fruiting forms at 9, 6, and 3 days before anthesis; at anthesis; and at 2, 4, 7, and 9 days after anthesis to determine if free IAA decreased because it was converted to a conjugat...

This study aimed to assess the chemical responses of forage watermelon fruit at different maturity stages or storage lengths, performing two experimental tests. In first test, four were assessed: 30, 45, 60, and 75 days after anthesis, with replicates. second fruits maintained under three lengths: T1D (harvest day), T3M (3 months harvest), T6M (6 eight Experimental design was completely randomi...

Regulatory processes controlling traits such as anthesis timing and whole-plant senescence are of primary importance for reproductive success and for crop quality and yield. It has previously been demonstrated that the presence of alleles associated with high grain protein content (GPC) at a locus on barley chromosome six leads to accelerated leaf senescence, and to strong (>10-fold) up-regulat...

The value of two heat sum methods, one linear (degree days > 5 degrees C) and the other curvilinear (period units), were assessed together with calendar days as predictors of the duration of microsporogenesis in seven natural stands of Norway spruce (Picea abies (L.) Karst.) and eleven natural stands of Scots pine (Pinus sylvestris L.). Microsporogenesis was divided into two subperiods: March 1...

In future climates, greater heat tolerance at anthesis will be required in rice. The effect of high temperature at anthesis on spikelet fertility was studied on IR64 (lowland indica) and Azucena (upland japonica) at 29.6 degrees C (control), 33.7 degrees C, and 36.2 degrees C tissue temperatures. The objectives of the study were to: (i) determine the effect of temperature on flowering pattern; ...

In the petals of some species of flowers, programmed cell death (PCD) begins earlier in mesophyll cells than in epidermal cells. However, PCD progression in each cell type has not been characterized in detail. We separately constructed a time course of biochemical signs and expression patterns of PCD-associated genes in epidermal and mesophyll cells in Lilium cv. Yelloween petals. Before visibl...
