در خاک های آهکی فسفر معمولا به صورت ترکیباتی نامحلول با کلسیم همراه بوده و گیاه غالبا از نظر جذب فسفر در این خاک ها دچار مشکل می باشد. به نظر می رسد برخی از ریز جانداران خاک نظیر باکتری های حل کننده فسفات (psb) و قارچ های میکوریزی آربوسکولار (am) قادر باشند با استفاده از مکانیزم های مختلف، فسفر را از شکل غیر قابل استفاده به شکل محلول و قابل استفاده تبدیل کنند. به منظور بررسی نقش باکتری های حل ک...

Maize was domesticated from teosinte, a wild grass, by approximately 6300 years ago in Mexico. After initial domestication, early farmers continued to select for advantageous morphological and biochemical traits in this important crop. However, the timing and sequence of character selection are, thus far, known only for morphological features discernible in corn cobs. We have analyzed three gen...

The domestication of maize (Zea mays ssp. mays) from its wild ancestor (Zea mays ssp. parviglumis) led to a loss of genetic diversity both through a population bottleneck and through directional selection at agronomically important genes. In order to discriminate between those effects and to investigate the nature of the domestication bottleneck, we analyzed nucleotide diversity data from 12 ch...

In this research, leaf area prediction model was developed for some leaf-used maize (Zea mays L.) cultivars namely Coluna, Luce, Maveric, Ranchero, TTM-813, Zamora and RX-788 grown in Black Sea region of Turkey. Lamina width, length and leaf area were measured without destroying the leaf to develop the models. The actual leaf areas of the plants were measured by PLACOM Digital Planimeter and mu...
