Suboptimal Winter Chilling Impedes Development of Acrotony in Apple Shoots

Unfrozen Water in Apple Shoots as Related to Their Winter Hardiness.

development of feminist poetics in adrienne rich

اشعار ریچ، به عنوان اشعاری که همیشه در حال تغییر و دگرگونی هستند، تجسمی از رشد و دگرگونیِ انسان هستد. پایان نامه ی حاضر، با تمرکز بر روی مراحل سیر شعری ریچ از تغییری در دنیا به عکس هایی فوری از یک عروس، سپس به شیرجه به درون کشتی شکسته و در نهایت به صبری عجیب مرا تا اینجا آورده، به بررسی این مراحل در قالب نظر شوالتر در رابطه با سه مرحله ی پیشرفت ادبی زنان یعنی مرحله ی زنانه، زن گرا و زن محور می پ...

The role of acrotony in reproductive development in Picea.

The expression of acrotony (i.e., the increasing size of comparable lateral shoots toward the apex of the main shoot) was similar among first-order shoots borne along previous-year leaders of young Picea glauca (Moench) Voss, Picea mariana (Mill.) B.S.P. and Picea rubens Sarg. trees. The position and nature (i.e., whether cones, second-order shoots or non-flushed buds) of lateral axes borne alo...

Anthocyanin accumulation in apple and peach shoots during cold acclimation

Experiments were conducted to investigate the effects of low temperatures on anthocyanin accumulation in apple and peach shoots. The anthocyanin concentration in both the apple and peach shoots increased rapidly during cold acclimation reaching the peak value in early December. The anthocyanin might be accumulated in shoots as a result of leucoanthocyanidin conversion. When apple and peach shoo...

Divergence of the diapause transcriptome in apple maggot flies: winter regulation and post-winter transcriptional repression.

The duration of dormancy regulates seasonal timing in many organisms and may be modulated by day length and temperature. Though photoperiodic modulation has been well studied, temperature modulation of dormancy has received less attention. Here, we leverage genetic variation in diapause in the apple maggot fly, Rhagoletis pomonella, to test whether gene expression during winter or following spr...
