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

Assessment of morphological attributes of Guava tree for design of a novel tunnel spraying system
The morphological attributes play a significant role in determining the level of applied insecticide by the existing spraying system. Therefore, this attempt was made to assess the various morphological attributes of guava tree such as leaf size, leaf ...

Estimating Leaf Area Index with Dynamic Leaf Optical Properties
Leaf area index (LAI) plays an important role in models of climate, hydrology, and ecosystem productivity. The physical model-based inversion method is a practical approach for large-scale LAI inversion.

Regional‐Scale Relationships of Leaf Area Index to Specific Leaf Area and Leaf Nitrogen Content
Specific leaf area (SLA) is an important link between vegetation water and carbon cycles because it describes the allocation of leaf biomass per unit of leaf area. Several studies in many vegetation types have shown that canopy SLA is closely related to canopy leaf nitrogen (N) content and photosynthetic capacity.

A General Leaf Area Geometric Formula Exists for Plants—Evidence from the Simplified Gielis Equation
Plant leaves exhibit diverse shapes that enable them to utilize a light resource maximally. If there were a general parametric model that could be used to calculate leaf area for different leaf shapes, it would help to elucidate the adaptive evolutional ...

Climate-change-related increases in the frequency and intensity of heatwaves affect viticulture, leading to losses in yield and grape quality. We assessed whether canopy-architecture manipulation mitigates the effects of summer stress in a Mediterranean ...

Spatial and temporal variations in leaf area index, specific leaf area and leaf nitrogen of two co-occurring savanna tree species [PDF]
Foliage growth, mass- and area-based leaf nitrogen concentrations (Nm and N a) and specific leaf area (SLA) were surveyed during a complete vegetation cycle for two co-occurring savanna tree species: Crossopteryx febrifuga (Afzel. ex G. Don) Benth. and Cussonia arborea A. Rich.
