Fungi associated with apple and pear sooty blotch and flyspeck diseases in Guilan province, Iran

Sooty blotch and flyspeck occur on fruit surfaces and result in economic losses due to less attractive appearance. Sooty blotch fungi form dark mycelial mats whereas flyspeck fungal agents are well characterized with black, sclerotium-like bodies on fruit surface. Whilst more than 60 species have been reported in association with these two fungal diseases, thus far they have not been studied in...

extraction and acetylation of purified trypsin from bovin pancreas and study of some its physico-chemical properties

آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...

Chemical-Free Cotton Defoliation by; Mechanical, Flame and Laser Girdling

A novel new way to achieve chemical-free defoliation of cotton is discussed. The research found that by severing the phloem tissue on the main stalk, via a girdling operation, the operation stimulated the cotton plant to alter its growth into an early senescence pathway that resulted in the plant shedding its leaves and opening up all its bolls, leaving the plant in the perfect state for machin...
