Nonphotosynthetic cells of higher plants depend on the supply of a carbon substrate, usually sucrose, for cellular metabolism. Typically this sucrose is synthesized in leaves from the products of photosynthesis. Because of the lack of light below ground, roots do not generally photosynthesize (we note the exception of certain mangrove species and members of the Orchidaceae), although many roots...

an experiment was conducted to study the effect on performance of silkworm bombyx mori l., when fed by leaves of different mulberry varieties a crd design with 12 tratments (including kamasari, kaeiryo ichinose, kaeerizhotezomigaeeshi, tachibana, ichinose, chekemaoha, yukishinogi, shin ichinose, wasemidori, roso, kenmochi, as well as some local varieties in 4 replications. the larvae were reare...

Abstract Plant breeding and seed technology are the two arms of crop improvement programmes. The ultimate goal any plant programme is to make available quality seeds new improved varieties in adequate quantity farmers. Modern techniques have enabled development with desired traits at a much higher pace than ever before, addressing challenges food nutritional security. A large number being bred ...

abstract during 2007 and 2008, a survey on species diversity of acari associated with pistachio trees and seasonal dynamics of the dominant injurious species was conducted in mahvelat region for the first time. 8 varieties of pistachio including akbari, owhadi, badami, barg siah, ghermez, kalah ghochi, germeh and momtaz, commonly grown in the region were compared in terms of infestation to the ...

BACKGROUND Gardeners and park managers seeking to support biodiversity in urban areas often plant ornamentals attractive to flower-visiting insects. There is a huge diversity of garden plant varieties, and some recommendations are available as to which are attractive to insects. However, these are largely not based on rigorous empirical data. An important factor in consumer choice is the range ...

irrigated barley is grown on about 50,000 hectares in the warm agro-climate zone in the south of iran. the average grain yield of barley in these areas is 2,000 kg/ha. wide adaptability and high grain yield stability are important assets for barley varieties to be grown by farmers. zahak barley cultivar was initially selected from international barley germplasm received from cymmit and based on...

Background: Genetically Modified (GM) foods are produced using genetic engineering. This survey attempted to identify the presence of GM rice varieties among some imported rice samples in Iran. Methods: From May to July 2016, a total of 50 samples of the imported rice to Iran were obtained, including 20 bulk rice samples from Bandar Abbas custom, Southern Iran and 30 retail rice samples from s...

in mulberry (morus sp.), grown for its foliage, which is the sole food for the silkworm (bombyx mori l.), evolving high yielding varieties is a long drawn and laborious process. one of the important selection parameter that has significant positive correlation with leaf yield is total shoot length [tsl] of the mulberry plant. measuring the length of all the shoots of the test genotypes to get t...
