Modeling of Shoot Elongation and Leaf Appearance in Potted Mulberry [PDF]

Plant Production Science, 2000
To predict mulberry growth, modeling of shoot elongation and leaf appearance of potted mulberries was attempted. Potted mulberries were grown in temperature-controlled phytotrons. Changes in the rates of mulberry shoot elongation and leaf appearance, and

Spring Wheat Leaf Appearance and Temperature: Extending the Paradigm? [PDF]

Annals of Botany, 2003
Extensive research shows temperature to be the primary environmental factor controlling the phyllochron, or rate of leaf appearance, of wheat (Triticum aestivum L.). Experimental results suggest that soil temperature at crown depth, rather than air temperature above the canopy, would better predict wheat leaf appearance rates.

Maize Leaf Appearance Rates: A Synthesis From the United States Corn Belt [PDF]

Frontiers in Plant Science, 2022
The relationship between collared leaf number and growing degree days (GDD) is crucial for predicting maize phenology. Biophysical crop models convert GDD accumulation to leaf numbers by using a constant parameter termed phyllochron (°C-day leaf−1) or ...

Simulating leaf appearance in a maize variety

Bioscience Journal, 2010
The calculation of leaf appearance rate (LAR) is an important part of many crop simulation models. The objective of this study was to evaluate and compare a linear model (the Phyllochron model) with a non-linear model (the Wang and Engel, WE, model) for ...

The Effect of Temperature on Leaf Appearance in Rice [PDF]

Annals of Botany, 1996
Temperature is the principal environmental determinant of crop leaf appearance. The objective of this study is to analyse whether there are different effects of day temperature (TD) and night temperature (TN) on main-stem leaf appearance in rice (Oryza sativaL.).

Relationship between Vessel Formation and Seasonal Changes in Leaf Area of Evergreen and Deciduous Species with Different Vessel Arrangements

Plants, 2021
To discuss the diversity of morphological traits and life strategies of trees, the functional relationship between leaf expansion and vessel formation must be clarified.

Wheat Developmental Traits as Affected by the Interaction between Eps-7D and Temperature under Contrasting Photoperiods with Insensitive Ppd-D1 Background

Plants, 2021
Earliness per se (Eps) genes are important to fine tune adaptation, and studying their probable pleiotropic effect on wheat yield traits is worthwhile. In addition, it has been shown that some Eps genes interact with temperature and therefore determining

Nitrogen nutrition index and morphogenesis in Alexandergrass of the Central Depression of Rio Grande do Sul

Ciência Rural, 2023
: This study assessed the nitrogen nutrition index, morphogenic characteristics and tiller structure of Alexandergrass (Urochloaplantaginea (LINK) Hitch) pasture submitted to different nitrogen (N) levels (zero, 150 or 300 kg ha-1 of N). The experimental

تأثیر سطوح شوری آب آبیاری با NaCl بر فیلوکرون و سرعت ظهور برگ ارقام جو [PDF]

تنش های محیطی در علوم زراعی, 2016
شوری منابع آب‌وخاک از مهم‌ترین مشکلات کشاورزی در مناطق خشک و نیمه‌خشک ایران است. برای بررسی تأثیر شوری آب آبیاری بر فیلوکرون و سرعت ظهور برگ ارقام جو، آزمایشی به‌صورت فاکتوریل در قالب طرح پایه بلوک‌های کامل تصادفی با سه تکرار در گلخانه دانشکده کشاورزی ...
