Nondestructive optical method for plant overall health evaluation

In vivo measurements of the optical properties of plant leaves, by spectrophotometric methods, could potentially provide very useful information for the assessment of the plant’s health. This paper describes a novel experimental set-up that enables continuous measurements of the optical reflection and transmission coefficients of broad-leaved plants. The optical spectral characteristics of leaves, in the broad wavelength range, are often a discussed topic in the scientific literature. Nevertheless, to the best of our knowledge, the real-time spectral analyses of the leaf haven’t been reported so far. Monitoring the evolution of the plant activity in real-time has resulted in the graph of the spectral Circadian rhythm as a function of time. The set-up was tested on Phaseolus vulgaris and the results of the measurements are presented and discussed

Tortula canescens Mont. was found for the first time in Basilicata (Matera city ‘Sasso Barisano’). The distribution of this species is restricted to Europe and the Mediterranean area. The discovery of this species is interesting because it is located in a habitat where it is more common to find T. muralis

During a bryological survey of the Marmore Waterfall, the species Fissidens rufulus and Barbula bolleana was identified and constitutes the first record for the Umbria Region. Conocephalum salebrosum at Sass Negher, province of Belluno, near Serrai di Sottoguda Natural Reserve constitutes the first record of for the Veneto Region
