تأثير بعض معقمات البذار الفطرية في إنبات، و النمو الخضري، و إنتاجية القمح، (صنف شام 3)‎ في المخبر و الحقل

Abstract EN

This experiment was carried out in 2007 /2008 under laboratory and field conditions effect of seed treatment with fungicides: Vita Flo, Dividend, Raxil and Penncnol at three concentrate : recommendations concentration (1X), (2X) and (4X) on emergence, growth, content of chlorophyll and yield of wheat (var.

cham 3 ) Data ؛ndicate that the seed treatment with fungicides at the recommended concentration( 1X) significantly increased the percent emergence compared with control.

On the contrary, showed Vita Flo and Penncnol at (2X) significantly reduced percent emergence compared with control.

On the other hand, The present result recorded that used fungicides at (4X) significantly reduced the percent emergence in all treatments compared with control.

Results indicated that different treatments, gave different effects on seedling length of wheat var.

cham3 with different concentrations.

Vita Flo, Dividend and Raxil at 1X significantly increased on seedling length: (22cm, 23cm and 23 cm respectively), compared with the control.

On the other hand, data indicated that used seed treatment at 4X significantly reduced the dry weight of roots compared with control, no significant differences were found among treatments.

Data indicated that the application of fungicides as seed treatment of at 1X significantly increased the concentration of the photosynthetic pigments, i.e.

chlorophyll a, b, and the ratio a/b as compared with the control.

Data indicated that seed treatment with fungicide at 1X and 2 X significantly increased 1000 - kernel weight and grain yield compared with the control.

In contrast, fungicides at 4X significantly reduced 1000 - kernel weight and grain yield compared with the control.
