agricultural practices always need accurate information about occurrence of particular developmental stages. data from planting dates trials conducted over the kabotar-abad agricultural research station, isfahan during 2003-2009 were used to develop models for estimating developmental stages duration of sofea safflower variety. to model duration of each developmental stage, duration of each dev...

1- introduction crop development is qualitative changes planned that led the plant to ripening. factors such as water available, nitrogen and photosynthetic materials are affected growth and development. under irrigated conditions expected that all of factors except climate elements be controlled. thus, only climate elements able to change of plant growth and development and under these conditi...

The effect of leachates of different phenological stages of Cassia occidentalis L. on Parthenium hysterophorus L. was studied. Seed germination, radicle length, plumule length and fresh and dry weight of Parthenium were recorded. Pigments and protein contents were also measured to evaluate relation between biochemical and biophysical parameters of Parthenium under stress. The leaf leachate of C...

in order to study adaptation ability of 15 commercial olive cultivars, this experiment was carried out using a randomized complete block design with three replication during the period from 2007 to 2009 in dry-warm climate of sar-pol-e-zehab dallaho olive station of kermanshah province. in this experiment, vegetative and reproductive traits were measured according to i.o.o.c. descriptors. flora...

in order to study fruit  quality changes in apple cultivar gala, related to ripening stage and storage time, an experiment was conducted in a split plot arrangement in randomized complete block design with four replicationsin the area of damavand– jaban for three years. five levels of sampling times in storage were assigned to main plots, and three levels of harvesting times were randomized in ...

Flowering of higher plants is orchestrated by complex regulatory networks through integration of various environmental signals such as photoperiod, temperature, light quality and developmental cues. In Arabidopsis, transcription of the flowering integrator gene FLOWERING LOCUS T (FT) that several flowering pathways converge to is directly regulated by more than ten transcription factors. Howeve...
