    Effect of different sowing densities on some characteristics of Isatis tinctoria L. and Isatis constricta Davis and on the recovery of indican
    (2007) Kızıl, Süleyman; Arslan, Neşet; Khavar, Khalid Mahmood
    The study reports the effects of four sowing densities (40 x 10, 40 x 20, 60 x 10 and 60 x 20 cm) on the agronomic characteristics of Isatis tinctoria and I. constricta under the rainfed conditions of South Eastern Anatolia. Wide row spacings of 60 x 10 or 60 x 20 cm were effective in obtaining maximum number of leaves per plant, leaf length, leaf width, petiole length, stem diameter, fruit length, 1000 fruit weight and 1000-seed weight. However, narrow row spacing (40 x 10 or 40 x 20 cm) led to maximum values of fresh and dry leaf yield 10 m -2, plant height, fruit yield and fruit length, minimum hull content, and the highest indican percentage and indican yield m-2. This information will be helpful for the economical cultivation of these plants under the rainfed conditions of South Eastern Anatolia.

    In Vitro Micropropagation of Fritllaria imperialis and F. persica using Different Portions of Leaf as Explant
    (Univ Agriculture, Fac Veterinary Science, 2024) Kizil, Suleyman; Khavar, Khalid Mahmood; Sesiz, Ugur
    Fritillaria imperialis and F. persica are important ornamental and medicinal plant species that grow naturally in large areas of the Middle East, Central, and Western Asia. These are counted as neglected crops and face lack of appropriate agronomic and biotechnological attention in development of propagation technologies. Therefore, the study aimed to micro propagate these two species using new explants of apical, middle, and basal portions of leaf from newly germinated seedlings for direct bulblet regeneration. The results testified the regeneration competency of the three explants of each species on six sets of naphthalene acetic acid (NAA) - benzyl aminopurine (BAP) modified Murashige and Skoog (MS) medium. The maximum number of 2.48 and 2.04 bulblets per explant on F. imperialis and F. persica was induced on basal portions of leaf on MS medium modified with 0.15 mg L-1 NAA+2.0 mg L-1 BAP and 0.1 mg L-1 NAA+2.0 mg L-1 BAP respectively. The regenerated bulblets were rooted on MS medium modified with 0.5 mg L(-1 )NAA and acclimatized in pots containing peat moss. Regardless of the explant types obtained from each species, all explants had the competence to regenerate new bulblets. A comparative analysis of morphological features of in vitro-grown plants with field-grown plants showed similarities. It was concluded that these methodologies could be exploited further for commercial micropropagation of both species without compromising the quality of the mother species.

    Introduction of economically important bulbous plants collected from wild flora in semi arid climatic conditions of southeastern anatolian region of turkey
    (International Society for Horticultural Science, 2015) Kızıl, Süleyman; Khavar, Khalid Mahmood; Arslan, Neşet
    Turkey has rich biodiversity due to its topography comprising of plains, plateaus and mountainous regions that has contributed to enrichment of its flora including bulbous plants. Many among these have potential for use in pharmaceutical and ornamental plant. However, owing to lack of proper research many among these have to be evaluated for commercial propagation yet. Leaves, bulbs and flowers among many of them are evaluated locally as salads, vegetables, to obtain products of pharmaceutical importance and flowers for use in cut flower and ornamental plant industries. The study aimed to find the suitable economically important plant geophytes that grow in the wild and could be successfully introduced into the Southeastern Anatolian climatic zones. The meet the objective, a field survey of bulbous geophytes of Southeastern and Eastern Anatolia was carried out during April-July periods of 2011 and 2012. The survey results indicated distribution of bulb geophytes at altitudes of 640-2651 m. The geophytes belonging to the genus Allium, Biarum, Bellevalia, Crocus, Eranthis, Fritillaria, Gladiolus, Hyacinthus, Iris, Ixillirion, Muscari, Narcissus, Ornithogalum, Sternbergia, Scilla, Tulipa, Ophyrs and Orchis were collected. After initial screening, it was decided to culture 40 species; the bulbs of these species were planted in the collection gardens of the Department of Field Crops, Dicle University, Diyarbakir for determination of many parameters including, flowering date, duration of flowering time and other agronomical characteristics important for bulbous species. The experimental results suggested that most of these geophytes among these have high domestication potential and could be evaluated for commercial production.
