Fruit of 85 varieties of Pakistani dates were collected throughout the harvest season. Appropriate Performa was designed to write the scientific and commonly used properties. These properties included fruit color at Khalal stage, shape, size (length & diameter), color & height of perianth, fruit group (soft, semi-dry, dry), edible stage and the micropyle position and split (wide, narrow, deep)....

this study investigated the effectiveness of heat treatment (50°c, 60°c and 70°c for 1 h and 2h at 75-80% rh) and cold treatment (0°c and-5°c for 24h and 48h) in the control of storage pests in zahedi and piyarom dates. before and after each treatment, the number of surviving adults, larvae, pupae and eggs were recorded and the percentage of infestation was calculated. the dates were treated at...

The effect of photoperiod and growing degree days (GDD) on dry matter and dry matter partitioning in Jerusalem artichoke was investigated during 2008-09 and 2009-10. Three Jerusalem artichoke genotypes (CN-52867, JA-89 and HEL-65) were planted in 15 day-intervals between with thirteen different dates (September 20 to March 20) atKhon Kaen University,Thailand. Jerusalem artichoke genotypes ...

in order to determine probable effects of sowing dates on partitioning coefficient of dry matter to different organs (leaf, stem and reproductive organs) in different wheat varieties (koohdasht, zagros and tajan) an experiment with crbd design and four replications was conducted. 5 sowing dates were included (29 december, 2007, 30 january, 2 march, 27 march, 1may, 2008). in order to quantify pa...

frost occurrence during plant growth created special conditions to evaluate the effects of planting date on dry matter content and agronomical characteristics of potato cultivars influenced by natural frost in field conditions. a split-plot experiment with three replications was carried out to compare three planting dates, as main plot, from 1 to 21 november with 10 day intervals and four culti...

in order to evaluate a better sowing date of chickpea cultivars in dry land conditions, a factorial experiment in randomized complete block design with four replications was carried out at research station of bahar (hamadan province) during 2005-2006 cropping season. two planting time included winter and spring and four chickpea cultivars (cvs.) including one local (check) and three improved cv...

background and objectives: sugar beet (beta vulgaris l.) is the major crop in khorasan province which is mainly grown in spring. however, autumn sowing has a lot of advantages including lower crop water requirement and higher water use efficiency. accordingly, this research was performed to compare the yield of storage organ in spring and autumn-sown sugar beet and determine the most appropriat...

The spatial patterns of the variability of the appearance dates of the honey bee Apis mellifera L. (Hymenoptera: Apidea) and the small white Pieris rapae (L.) (Lepidoptera: Pieridae) were investigated in Spain. A database of more than 7,000 records of the dates of the first spring sightings of each species in more than 700 localities from 1952-2004 was used. Phenological data were related to sp...
