Growth, as well as Leaf and Stem Anatomy in Periwinkle Plant as Affected by Certain Biotic and Abiotic Elicitors

Abiotic and biotic elicitors’ effects on secondary metabolites biosynthesis of periwinkle (Catharanthus roseus (Linn.) G. Don)

Based on recent statistical survey, the cancer is the third important factor in Iran mortality. Vinblastine and vincristine alkaloids are dominantly biosynthesized in the aerial parts of periwinkle, broadly applied for cancer treatment. Therefore, over production of these alkaloids by using the biotechnological approaches is inevitable. Since the terpenoid indole alkaloids (TIAS) biosynthesis p...

Sunflower morphology and yield as affected by foliar applications of plant growth regulators

Plant height of sunflower is a major agronomic trait affecting crop performance in the field and its adaptation to mechanical harvest. Field experiments were conducted to study the effect of foliar application of paclobutrazol (PBZ) at 12.5 g ai/ha, mepiquat chloride (MPC) at 25.0 g ai/ha and chlormequat chloride (CCC) at 1,500 g ai/ha in single or double applications on sunflower plant mor...

Growth of Rhizopus Suinus as Affected by Certain Growth Factors.

A relatively large amounit of w-ork has been done relevanit to definite comipounds which show growth-pronmoting aetivities. A review of the investigations dealing with the effects of these known growth factors for lower plants, exclusive of yeast, reveals several interesting aspects. The degree of the necessity of any factor referred to is liiiiited by the conditions of the test coniducted and ...

assessing metacognitive awareness and learning strategies as positive predictors in promoting l2 learners’ reading comprehension

the purpose of this thesis was to investigate how differently metacognitive, cognitive, and social/affective strategies affect l2 learners’ reading comprehension. to this end, the study employed a quasi-experimental design with a placement test as a proficiency test to find the homogeneity of groups. three classes were randomly selected as the experimental groups (n =90), and each class was tau...
