; Righetti et al., 2007 ; Tanner, 1949 ) were evaluated to demonstrate how ratio-based assessments of CO 2 assimilation are strongly dependent on leaf size. Net photosynthetic rates (μmol·m −2 ·s −1 ) are usually expressed on a leaf-area basis. When we

Plant leaf area is an important determinant of light interception and consequently of transpiration, photosynthesis, and plant productivity ( Goudriaan and Van Laar, 1994 ). Plant physiologists and agronomists have demonstrated the importance of

canopy growth of greenhouse crops ( Fan et al., 2015 ; Zúñiga, 2014 ). In previous studies, models of leaf area, leaf number, growing degree days, and dry matter distribution ( Gijzen et al., 1998 ; Kahlen, 2006 ; Marcelis et al., 1992 , 1998 ; Uzun

in almond trees), flower induction is related to the spur leaf area in the previous year and fruit bearing decreases the probability that a spur can bear flowers in the next year in comparison with spurs with similar leaf area that did not bear fruits

, 1990 ; Tucker, 1977 ), and the factors involved in regulating axillary initiation and growth are not well understood. Leaf area distribution in a tomato canopy is important for maximizing plant photosynthetic capacity ( Wolk et al., 1983 ) and

the loss of papaya leaf area are wind damage, spider mites, powdery mildew, and senescence. The loss of leaf area from high winds can significantly reduce fruit growth and sweetness ( Zhou et al., 2000 ). Papaya leaves can range from 50 to 70 cm wide

As the Pacific Northwest fruit industry shifts to precision-based management strategies for their orchards, tools are needed to understand tree physiology in the orchard to optimize fruit quality. Leaf area index is the ratio between the summed area

In the horticultural crop production of leafy vegetables, it is of practical importance to monitor crop size indicators such as the leaf area index (LAI), leaf fresh weight (LFW), and leaf length (LL). LAI, defined as half the total leaf area per

The productivity of a crop depends on the ability of plant cover to intercept incident radiation; this is a function of the leaf area available, the architecture of the vegetation cover, and the efficiency of the conversion of energy captured by
