Approaches to Modeling Potato Leaf Appearance Rate [PDF]

open access: yesAgronomy Journal, 2006
Two approaches quantifying potato (Solanum tuberosum L. cv. Kennebec) leaf appearance rates were evaluated: a thermal time approach using the phyllochron, and a nonlinear temperature response approach using a modified β distribution function. Leaf appearance measurements at six temperature treatments (14/10, 17/12, 20/15, 23/18, 28/23, and 34/29°C ...

Incorporating a chronology response into the prediction of leaf appearance rate in winter wheat. [PDF]

open access: yesAnnals of Botany, 2003
The prediction of leaf appearance rate (LAR) is an important part of many crop simulation models. Most wheat simulations models assume that LAR is affected by temperature and photoperiod. This assumption ignores the fact that seed reserves contribute to a greater LAR of the first two leaves and that the LAR of subsequent leaves decreases as a result of

Simulating leaf appearance in a maize variety

open access: yesBioscience 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 ...

An analysis of leaf growth in sugar beet. II: Leaf appearance in field crops

open access: yesAnnals of Applied Biology, 1985
SUMMARYThe influence of season, and certain agronomic treatments (irrigation, nitrogen fertiliser, density of planting and sowing date) on leaf number were analysed in a series of sugar‐beet crops grown during the five seasons 1978‐82. Leaf appearance was a linear function of thermal time (accumulated temperature above 1°C) and could be described by ...

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

open access: yesPlants, 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

open access: yesPlants, 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

Overexpression of PtoCYCD3;3 Promotes Growth and Causes Leaf Wrinkle and Branch Appearance in Populus

open access: yesInternational Journal of Molecular Sciences, 2021
D-type cyclin (cyclin D, CYCD), combined with cyclin-dependent kinases (CDKs), participates in the regulation of cell cycle G1/S transition and plays an important role in cell division and proliferation.

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

open access: yesتنش 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 ...
