The objective of this work is to evaluate the agronomic, phenological, nutritional quality and organoleptic characteristics of pistachios (Pistacia vera L.) based on the NDVI (Normalized Difference Vegetation Index) calculated in the phenological stage of nut filling from Sentinel satellite imagery. Based on this index, three pistachio tree orchards were studied and classified into two levels of vigour: high and low. The results obtained have discriminated the production per tree, which is strongly related to yield. Regarding the nutritional quality parameters, significant differences were not observed between vigour levels, although the most vigorous trees have shown nuts with a higher percentage of fibre and protein. In terms of phenology, there have not been differences between trees of different vigour, only a slight advance of some phenological stages has been observed in several high-vigour trees. Triangular tests have been made successfully to discriminate the origin of the dry nut and the vigour of the trees. In conclusion, for a given nut quality within a given orchard, the NDVI is a good index to classify different areas according to productive capacity and can be useful to apply variable management, irrigation and fertilization according to vigour.

Quantitative microbiological analysis by dilution plating method of pollen and additional male and female catkins, leaves of Betula verrucosa Ehrh. and its two cultivars: ‘Purpurea’ and ‘Youngii’ relatively of flowering period of Betula has been realized with the aim to provide new knowledge of the microbiological quality of anemophilous pollen for processing and its further application. Qualitative microbiological analysis with MALDI-TOF MS Biotyper was used in the identification of aerobic, anaerobic mesophilic bacteria and coliforms. Mixed microbiota was determined, consisting of aerobic (4.68–4.89 log cfu/g) and anaerobic (3.30–3.48 log cfu/g) mesophilic bacteria, lactobacilli (0–3.48 log cfu/g), coliform bacteria (0–4.57 log cfu/g), fungi and yeast (3.78–3.95 log cfu/g) on the pollen grains, that indicates acceptable quality in comparison with the microbiological quality parameters for bee pollen. Pantoea agglomerans was found associated with pollen of Betula verrucosa Ehrh. Recommendations on the collection of anemophilous pollen were established.

The effects of four mechanical pruning treatments [hedging, topping, hedging/topping, and hand-pruning (control)] on nut yield, nut quality, alternate bearing, and growth of 14-year-old female `Kerman' pistachio trees on Pistacia atlantica L. rootstocks were assessed. A single pruning was done before an “off,” or low-crop, year followed by retopping of those treatments incorporating topping the first year. Over 7 years, yields of hedged/topped and topped trees were equal to those of control trees, while hedged trees produced significantly less. The incidence of nonsplit shells and blank nuts were not affected by pruning. Nuts weighed more all years for hedged/topped and topped trees than for the others. Alternate-bearing indices within 7 years were lower for pruning treatments incorporating topping. Topping mitigated the fluctuating annual vegetative growth pattern and resulted in 27% of the shoots retaining buds through three successive alternate-bearing cycles after the year of treatment. Hedged/topped and topped trees had significantly less alternation in annual girth growth than control or hedged trees. These results demonstrated that two successive seasons of mechanical topping, started before the off year, produced changes in shoot growth, trunk growth, and bud retention that mitigated alternate bearing through three biennial cycles, without decreasing yield. Thus, severe annual hand-pruning could be used to prevent or minimize alternate bearing of pistachios.

<p><em>Fumaria parviflora</em> Lamk., is a valued herb in Ayurvedic medicine and is used as Parpata by majority of Ayurvedic practitioners amongst the other plant sources mentioned under the same common name. It is found in many parts of India from Indo-Gangetic plain and Nepal down to the Nilgiri Mountains. The whole plant is diuretic, diaphoretic, aperient, laxative and anthelmintic. It is used as antipyretic, blood purifier and in skin disorders. In the present study, physico-chemical parameters were established for identification of the drug. Protopine and <em>β</em>-sitosterol were quantified by validated HPTLC method, developed using precoated silica gel plates as a stationary phase and toluene: ethyl acetate: diethyl amine (7: 2: 1) and toluene: methanol (9.4: 0.6) as a mobile phase respectively. It is a diffuse, annual herb with thin winged stem; alternate leaf<strong><em> </em></strong>finely divided into small, linear lanceolate segments, small white or pink flowers with purplish tips. Microscopically root can be characterized by the presence of centrally located diarch primary xylem encircled by wide secondary xylem occupying major area and a narrow cork; stem by collenchymatous hypodermis, vascular bundle capped with lignified pericyclic fibres and hollow pith; leaf by vascular bundles with groups of sclerenchyma underneath the phloem and narrow spongy parenchymatous lamina. Powder<strong><em> </em></strong>can be typified by xylem vessels with varied thickening, lignified and thick walled testa and spherical pollen grains. The plant was found to be rich in alkaloids. The amount of protopine and <em>β</em>-sitosterol were found to be 0.47 – 0.50% w/w and 0.23 – 0.26% w/w.   The quality parameters and HPTLC method developed would serve as useful gauge in standardization of <em>Fumaria parviflora</em>.</p>
