The article presents the results of studying of ripening and storage of the introduced apple cultivar fruits in terms of arid zone of Central Kazakhstan (Zhezkazgan Botanical garden). The results showed that apple cultivars considerably differ on ripening and storage terms. The dispersive and correlation analyses of data have shown that the weight of fruits depends on conditions of the vegetative period. The weight loss fruits of late ripening are significantly higher than the grade of the early period with a probability of 99 %.

This study was carried out at the research field of Tarbiat Modares University, Peykan Shahr, Tehran to determine the changes in the content and chemical compositions of essential oil of tulsi (Ocimum. sanctum L.) at three different growth stages including vegetative, flower bud formation and full flowering stages. The essential oils of the aerial parts were extracted by hydrodistillation method using Clevenger apparatus, and analyzed by GC and GC-MS. The hydro-distillation of the aerial parts of Ocimum. sanctum at the vegetative, flower bud formation, and full flowering stages yielded 0.95%, 0.87% and 1.3% (w/w) EO, respective¬ly. The main constituent of the EO from the vegetative stage were 1, 8-Cineole and β-bisabolen, while eugenol was found as the main compound of flower bud formation and full flowering developmental stages.

Deoiled cakes of Neem and Jatropha served as source of diversified nutrition for Pseudomonas flourescens when used as substrate for mass culturing of antagonist. The present investigation were undertaken to test the suitability of neem and Jatropha cakes for liquid Concentration and longevity of Pseudomonas flourescens in vitro. Increasing the dilution of stock of initial inoculums resulted in decrease of total viable counts of Pseudomonas flourescens was comparatively highest population (64.67×105) and (201.67×105) lesser after 15 days than after 7 days of inoculation on Neem and Jatropha cake concentration respectively.
