The expression of many nuclear genes in plants is light regulated. We have examined the fluence-response, time-course, and reciprocity characteristics of four nuclear, blue-light-regulated transcripts in Pisum sativum L. var Alaska: Cab RNA, pEA207 RNA, pEA215 RNA, and pEA25 RNA. To avoid complications due to blue-light-induced transformation of phytochrome, we have adapted the procedure of mea...

Limited time for crop residue decomposition and complete seedbed preparation in double-cropping necessitates reduced tillage which is associated with its shortcomings. Information about seedbed preparation aspects in double-cropping of wheat and mungbean in Isfahan is lacking. For this reason, the effects of various seedbed preparation methods on growth, seed yield and yield components of mungb...

The growth and tuberization of potatoes (Solanum tuberosum L.) maintained for 6 weeks under four different regimes of continuous irradiance were compared to plants given 12 hours light and 12 hours dark. Treatments included: (a) continuous photosynthetic photon flux of 200 micromoles per square meter per second cool-white fluorescent (CWF); (b) continuous 400 micromoles per square meter per s...

Objective: Wheat is the most important crop in Iran. Self sufficiency in wheat production is one of the economic and food safety policies in the country. In spite of the efforts which have been made in this area, the mean of wheat yield in Iran is less than its world average. Methods: In order to identifying of the high yielding wheat lines with optimal characteristics and to determine the trai...
