“…Hence, all these cultivars need pollens from other olive cultivars to produce a high yield in terms of fruit production. (Iqbal et al, 2019 b ). Huge olive orchards have been established in this region since the last decade which is mostly dominated by the Italian olive cultivars.…”

The final fruit yield is significantly correlated to fruit set which is directly dependent upon self-incompatibility (SI), pollination ability, extent of cross-compatibility among cultivars, and prevailing environmental conditions especially suitable temperature regimes during anthesis. Four Italian cultivars viz. Coratina, Frantoio, Ottobratica, and Leccino under the agro-climatic conditions of Pothwar (Pakistan) were included in these studies during the years of 2017 & 2018. Each variety exhibited different values for the initial fruit set, final fruit set, number of shotberries and extent of selfincompatibility index. The SI resulted through reciprocal crosses depicted that cv. Coratina (0.80), cv. Frantoio (0.67) and cv. Leccino (0.73) possessed partial self-incompatibility while cv. Ottobratica (0.43) was found completely selfincompatible in studied environmental conditions. Cross-compatibility results based on fruit set percentage indicated that the cultivars can efficiently pollinize other cultivars and set good fruit yield, however, the cultivars pairs Coratina/Frantoio was at top and pair of Ottobratica/ Leccino was at the bottom. Thus, the selection and plantation of suitable pollinizers in olive orchards is a prerequisite through which deficiency in fruit setting and attaining commercial yield in olive orchards could be achieved.

“…In the recent decade, olive farming has gained popularity because of its high socioeconomic value. In Pakistan, olive production project was established in the Potohar region, where more than 3,166 acres of olive plants were planted [ 28 ]. According to Pakistan Agricultural Research Council (PARC), total number of trees planted in Pakistan are now 2.95 million [ 29 ].…”

Morpho-anatomical determinants of yield potential in Olea europaea L. cultivars belonging to diversified origin grown in semi-arid environments

Plant performance is mainly estimated based on plant architecture, leaf features and internal microstructural changes. Olive (Olea europaea L.) is a drought tolerant, oil yielding, and medium sized woody tree that shows specific structural and functional modifications under changing environment. This study was aimed to know the microstructural alteration involving in growth and yield responses of different Olive cultivars. Eleven cultivars were collected all over the world and were planted at Olive germplasm unit, Barani Agricultural Research Institute, Chakwal (Punjab) Pakistan, during September to November 2017. Plant material was collected to correlate morpho-anatomical traits with yield contributing characteristics. Overall, the studied morphological characters, yield and yield parameters, and root, stem and leaf anatomical features varied highly significantly in all olive cultivars. The most promising cultivar regarding yield was Erlik, in which plant height seed weight and root anatomical characteristics, i.e., epidermal thickness and phloem thickness, stem features like collenchymatous thickness, phloem thickness and metaxylem vessel diameter, and leaf traits like midrib thickness, palisade cell thickness a phloem thickness were the maximum. The second best Hamdi showed the maximum plant height, fruit length, weight and diameter and seed length and weight. It also showed maximum stem phloem thickness, midrib and lamina thicknesses, palisade cell thickness. Fruit yield in the studied olive cultivars can be more closely linked to high proportion of storage parenchyma, broader xylem vessels and phloem proportion, dermal tissue, and high proportion of collenchyma.

Fruits of five different varieties of Olea europea were taken from the farms cultivated in Pothohar region of Pakistan. Oils were extracted using cold press technique. Different colored oils were obtained in different yields. Physicochemical parameters were carried out by American Oil Chemists Society (AOCS) official methods. Fatty acid profiles were calculated by gas chromatograph equipped with flame ionization detector, after methanolic esterification of olive oils. The most abundant of the fatty acids was oleic acid (62.1-70.15%). The yield percentages (15.3-17.7%), moisture contents (0.4-0.73%), refractive indices (1.4689-1.4691 at 20ºC, 1.4613-1.4615 at 40ºC, 1.4537-1.4540 at 60ºC), saponification value (188-191 mg KOH/g), colors measured by Lovibond tintometer (20Y/2-6 R), acid value (0.17-0.44 mg KOH/g), peroxide value (7.83-17.75 meq/Kg), free fatty acid value (0.08-0.22), iodine value (87-92) were determined. Olive cultivars from Pothohar region indicated very close characteristics to the standard olive oil recommended by International Olive Oil Council (IOOC). Characterized local olive cultivars can contribute as an import substitute of edible oil and a lot of foreign exchange can be saved, as well as lot can be earned by exporting it.
