Paclobutrazol and Reduced Humidity Improve Resistance to Wilting of Micropropagated Grapevine

Relationships between leaf conductance to CO2 diffusion and photosynthesis in micropropagated grapevine plants, before and after ex vitro acclimatization.

In vitro-cultured plants typically show a low photosynthetic activity, which is considered detrimental to subsequent ex vitro acclimatization. Studies conducted so far have approached this problem by analysing the biochemical and photochemical aspects of photosynthesis, while very little attention has been paid to the role of leaf conductance to CO(2) diffusion, which often represents an import...

the usefulness of mycorrhizal fungi to mitigate weaning stress in micropropagated grapevine plantlets

abstract large-scale mortality of in vitro raisedplantlets occurred during acclimatization, i.e. glasshouse hardening, and later at field transfer still has remained as a significant bottleneck in micropropagation. the usefulness potential of some arbuscular mycorrhizal fungi (amf) to minimize mortality rate of three commercial grape rootstock genotypes during glasshouse acclimatization was stu...

Resistance of Aerosolized Bacterial Viruses to Relative Humidity and Temperature.

The use of aerosolized bacteriophages as surrogates for hazardous viruses might simplify and accelerate the discovery of links between viral components and their persistence in the airborne state under diverse environmental conditions. In this study, four structurally distinct lytic phages, MS2 (single-stranded RNA [ssRNA]), ϕ6 (double-stranded RNA [dsRNA]), ϕX174 (single-stranded DNA [ssDNA]),...

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...
