[Method] Paraffin section technique combined with field investigation method were adopted to conduct com- parative analysis of shoot histomorphology and phenological phases between two Io- quat varieties, ＇Chuanzao Loquat＇ and ＇Zaozhong 6＇. [Result] ＇Chuanzao Loquat＇ branched out and unfolded leaves about half to a month earlier than ＇Zaozhong 6＇; both the flowering and fruiting phases of ＇Chuanzao Loquat＇ were three months earlier than a precocious variety, ＇Zaozhong 6＇; the proportions of epidermis, cortex parenchyma, vascular tissue and medulla were 3.7%, 14.5%, 15.9% and 65.9%, re- spectively, in spdng shoots of ＇Chuanzao Loquat＇, and 3.1%, 42.5%, 6.9% and 47.5%, respectively, in ＇Zaozhong 6＇. [Conclusion] In terms of phenological phases, ＇Chuanzao Loqua＇ is earlier than ＇Zaozhong 6＇, a currently widely planted precocious variety, and thus is an important germplasm resource of Ioquats.展开更多

The emphasis was made especially for the components (relief, climate, soils), having substantial impact on the growth and yield of citrus. Morpho-metric analysis (biometric indicators, end of fetal maturity, starting of maturity, frost resistance, etc.) of frost resistant Tangerine-Tiakhara Unshiu from Japan and Saadreo and Adreula (Early ripe) has been conducted. For the application of landscape multifactor (multi-component) method, which takes into account the role of each component in the spread of citrus, the most important parameters are the following: relief (dismemberment, slope, aspect), climate (temperature inversions, sum of active temperatures, hydrothermal coefficient, etc.), soil conditions. Using this method and morphometric analysis, it became possible ranking of frost resistant tangerine (GIS-technologies) based on the landscape, the result of which has been determined that the frost resistant tangerine varieties in western Georgia has a high yield in the higher subtropical zone.展开更多
